Accounting Policies [Abstract]
BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Owens Corning, a Delaware corporation, is a leading global producer of glass fiber reinforcements and other materials for composite systems and of residential and commercial building materials. The Company operates within three segments: Composites, which includes the Company’s Reinforcements and Downstream businesses; Insulation and Roofing. Through these lines of business, Owens Corning manufactures and sells products worldwide. The Company maintains leading market positions in many of its major product categories. General On February 2, 2017, the Board of Directors declared a quarterly dividend of $0.20 per common share payable on April 3, 2017 to shareholders of record as of March 10, 2017. During 2016, the Company discovered an error in which certain Value Added Tax ("VAT") balances were inappropriately reported gross versus net in the Consolidated and Condensed Consolidating (Non-Guarantor Subsidiaries) Balance Sheets. We revised the December 31, 2015 balance sheet in these financial statements to correctly report the related VAT balances as either a net asset or a net liability. As of December 31, 2015, this resulted in a decrease to the previously reported Other current assets of $30 million , Other non-current assets of $24 million and Accounts payable and accrued liabilities of $54 million . These revisions were deemed immaterial to the current and prior periods and had no impact on the Consolidated and Condensed Consolidating Statements of Earnings or the Consolidated and Condensed Consolidating Statements of Cash Flows. During the fourth quarter of 2016, the Company adopted Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") No. 2016-09. This adoption resulted in the recognition of a previously unrecognized deferred tax asset as of January 1, 2016. Please refer to the accounting pronouncements section of Note 1, Note 16 and Note 20 for additional detail on this adoption. Basis of Presentation Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes refer to Owens Corning and its subsidiaries. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States. Principles of Consolidation The Consolidated Financial Statements of the Company include the accounts of majority-owned subsidiaries. Intercompany accounts and transactions are eliminated. Reclassifications Certain reclassifications have been made to the 2015 and 2014 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2016 . Use of Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Revenue Recognition Revenue is recognized when title and risk of loss pass to the customer and collectability is reasonably assured. Provisions for discounts and rebates to customers, returns and other adjustments are provided in the same period that the related sales are recorded and are based on historical experience, current conditions and contractual obligations, as applicable. Cost of Sales Cost of sales includes material, labor, energy and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Provisions for warranties are provided in the same period that the related sales are recorded and are based on historical experience, current conditions and contractual obligations, as applicable. Distribution costs include inbound freight costs; purchasing and receiving costs; inspection costs; warehousing costs; shipping and handling costs, which include costs incurred relating to preparing, packaging, and shipping products to customers; and other costs of the Company’s distribution network. All shipping and handling costs billed to the customer are included as net sales in the Consolidated Statements of Earnings. Marketing and Advertising Expenses Marketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications, which are expensed the first time the advertisement takes place. Marketing and advertising expenses for the years ended December 31, 2016 , 2015 and 2014 were $105 million , $98 million and $100 million , respectively. Science and Technology Expenses The Company incurs certain expenses related to science and technology. These expenses include salaries, building and equipment costs, utilities, administrative expenses, materials and supplies associated with the improvement and development of the Company’s products and manufacturing processes. These costs are expensed as incurred. Earnings per Share Basic earnings per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect the dilutive effect of common equivalent shares and increased shares that would result from the conversion of equity securities. The effects of anti-dilution are not presented. Cash, Cash Equivalents and Restricted Cash The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased. On the Consolidated Statements of Cash Flows, the total of Cash, cash equivalents and restricted cash includes restricted cash of $6 million as of December 31, 2016. On the Consolidated Balance Sheets, restricted cash is included in Other current assets. There were no restricted cash amounts for the previous time periods presented in the Consolidated Financial Statements. Restricted cash represents amounts received from a counterparty related to its performance assurance on an executory contract. These amounts are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion. Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is an estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered. Inventory Valuation Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at lower of cost or market and expense estimates are made for excess and obsolete inventories. Cost is determined by the first-in, first-out (“FIFO”) method. Investments in Affiliates The Company accounts for investments in affiliates of 20% to 50% ownership when the Company does not have a controlling financial interest using the equity method under which the Company’s share of earnings and losses of the affiliate is reflected in earnings and dividends are credited against the investment in affiliate when declared. Investments in affiliates are recorded in Other non-current assets on the Consolidated Balance Sheets and as of December 31, 2016 and 2015 , the total value of investments was $50 million and $54 million , respectively. Goodwill and Other Intangible Assets Goodwill assets are not amortized but are tested for impairment on at least an annual basis. In the current year, as part of the annual assessment, the Company used a quantitative approach to determine whether the fair value of a reporting unit was less than its carrying amount. As part of our testing process for goodwill the Company estimates fair values using a discounted cash flow approach from the perspective of a market participant. Significant estimates in the discounted cash flow approach are cash flow forecasts of our reporting units, the discount rate, the terminal business value and the projected income tax rate. The cash flow forecasts of the reporting units are based upon management’s long-term view of our markets and are the forecasts that are used by senior management and the Board of Directors to evaluate operating performance. The discount rate utilized is management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt rating and stock volatility, as measured by beta. The projected income tax rates utilized are the statutory tax rates for the countries where each reporting unit operates. The terminal business value is determined by applying a business growth factor to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, we would evaluate whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill impairment testing. Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include projected cash flows, discount rate, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Indefinite-lived intangible assets purchased through acquisition are generally tested qualitatively for impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years. Identifiable intangible assets with a determinable useful life are amortized over that determinable life. Amortization expense for the years ended December 31, 2016 , 2015 and 2014 was $25 million , $22 million and $21 million , respectively. See Note 5 to the Consolidated Financial Statements for further discussion. Properties and Depreciation Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation when assets are disposed of or otherwise retired. Precious metals used in our production tooling are included in property, plant and equipment and are depleted as they are consumed during the production process. Depletion typically represents an annual expense of less than 3% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of Earnings. For the years ended December 31, 2016 , 2015 and 2014 depreciation expense was $318 million , $278 million and $283 million , respectively. In 2016 , 2015 and 2014, depreciation expense included $19 million , $3 million and $1 million , respectively, of accelerated depreciation related to restructuring actions further explained in Note 11 to the Consolidated Financial Statements. In 2014, depreciation expense also included $3 million of impairment losses on held for sale assets. The range of useful lives for the major components of the Company’s plant and equipment is as follows: Buildings and leasehold improvements 15 – 40 years Machinery and equipment Furnaces 4 – 15 years Information systems 5 – 10 years Equipment 5 – 20 years Expenditures for normal maintenance and repairs are expensed as incurred. Asset Impairments The Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. This requires significant assumptions including projected cash flows, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Changes in management intentions, market conditions or operating performance could indicate that impairment charges might be necessary that would be material to the Company’s Consolidated Financial Statements in any given period. Income Taxes The Company recognizes current tax liabilities and assets for the estimated taxes payable or refundable on the tax returns for the current year. Deferred tax balances reflect the impact of temporary differences between the carrying amount of assets and liabilities and their tax basis. Amounts are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. In addition, realization of certain deferred tax assets is dependent upon our ability to generate future taxable income. The Company records a valuation allowance to reduce its deferred tax assets to the amount that it believes is more likely than not to be realized. In addition, the Company estimates tax reserves to cover potential taxing authority claims for income taxes and interest attributable to audits of open tax years. Taxes Collected from Customers and Remitted to Government Authorities and Taxes Paid to Vendors Taxes are assessed by various governmental authorities at different rates on many different types of transactions. The Company charges sales tax or Value Added Tax (“VAT”) on sales to customers where applicable, as well as captures and claims back all available VAT that has been paid on purchases. VAT is recorded in separate payable or receivable accounts and does not affect revenue or cost of sales line items in the income statement. VAT receivable is recorded as a percentage of qualifying purchases at the time the vendor invoice is processed. VAT payable is recorded as a percentage of qualifying sales at the time an Owens Corning sale to a customer subject to VAT occurs. Amounts are paid to the taxing authority according to the method and collection prescribed by local regulations. Where applicable, VAT payable is netted against VAT receivable. The Company also pays sales tax to vendors who include a tax, required by government regulations, to the purchase price charged to the Company. Pension and Other Postretirement Benefits Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover and medical costs. Derivative Financial Instruments The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. To the extent that a derivative is effective as a cash flow hedge, the change in fair value of the derivative is deferred in accumulated other comprehensive income/deficit (“OCI”). Any portion considered to be ineffective is reported in earnings immediately. To the extent that a derivative is effective as a fair value hedge, the change in the fair value of the derivative is offset by the change in the fair value of the item being hedged in the Consolidated Statements of Earnings. See Note 4 to the Consolidated Financial Statements for further discussion. Foreign Currency The functional currency of the Company’s subsidiaries is generally the applicable local currency. Assets and liabilities of foreign subsidiaries are translated into United States dollars at the period-end rate of exchange, and their Statements of Earnings and Statements of Cash Flows are converted on an ongoing basis at the monthly average rate. The resulting translation adjustment is included in accumulated OCI in the Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Equity. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the Consolidated Statements of Earnings as incurred. The Company recorded a foreign currency transaction loss of $2 million , $5 million and $4 million during the years ended December 31, 2016 , 2015 and 2014 , respectively. Accounting Pronouncements The following table summarizes recent accounting standard updates ("ASU") issued by the Financial Accounting Standards Board (the "FASB") that could have an impact on the Company's Consolidated Financial Statements: Standard Description Effective Date for Company Effect on the Consolidated Financial Statements Recently issued standards: ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)," as amended by ASU's 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20. This standard outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. Entities can adopt this standard either through a retrospective or modified-retrospective approach. January 1, 2018 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. We expect to complete our assessment in the second half of 2017 and plan to use the modified-retrospective method of adoption. Many of our customer volume commitments are short-term (as explained on pg. 5 of Item 1A Risk Factors) and contain single performance obligations. As a result, we do not expect many elements of this standard to be applicable to our business model. Under our current accounting policy (as described in Note 1 of the Consolidated Financial Statements), we recognize revenue when title and risk of loss pass to the customer and collectability is reasonably assured, and we estimate variable consideration based on historical experience, current conditions and contractual obligations. We believe our current variable consideration estimates are largely consistent with the new standard, but we are still analyzing potential quarterly timing differences for our consignment sales arrangements and customized products manufactured for customers. We are also still assessing the standard's new disclosure requirements, including the disaggregation of segment revenue. ASU 2016-01 "Financial Instruments - Overall (Subtopic 825-10)" This standard modifies certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The update eliminates certain disclosure requirements for financial instruments measured at amortized cost, requires that disclosure of financial instruments be based on an exit price notion, and requires separate presentation of financial assets and liabilities by measurement category and form of financial asset. January 1, 2018 We do not expect the adoption of this standard to have a material impact on our Consolidated Financial Statements. ASU 2016-02 "Leases (Topic 842)" The standard requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. The recognition and presentation of expenses will depend on classification as a finance or operating lease. Entities will adopt this standard through a retrospective approach. January 1, 2019 We are currently assessing the potential impact of this standard adoption on our financial reporting processes and disclosures. We believe that our adoption of the standard will likely have a material impact to our Consolidated Balance Sheets for the recognition of certain operating leases as right-of-use assets and lease liabilities. Our operating lease obligations are described in Note 8 of the Consolidated Financial Statements. We are in the process of analyzing our lease portfolio and evaluating systems to comply with the standard's retrospective adoption requirements. ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326)" This standard replaces the incurred loss methodology for recognizing credit losses with a current expected credit losses model and applies to all financial assets, including trade receivables. Entities will adopt the standard using a modified-retrospective approach. January 1, 2020 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. Our current accounts receivable policy (as described in Note 1 of the Consolidated Financial Statements) uses historical and current information to estimate the amount of probable credit losses in our existing accounts receivable. We have not yet analyzed our current systems and methods to determine the impact of using forward-looking information to estimate expected credit losses. ASU 2016-16 "Income Taxes (Topic 740)" This standard clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. January 1, 2018 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. Recently adopted standards: ASU 2014-15 "Presentation of Financial Statements - Going Concern (Subtopic 205-40)" This standard provides guidance on management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures in the event of such doubt. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2015-07 "Fair Value Measurement (Topic 820)" This standard removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. This standard permitted us to separately present certain assets in the pension plan assets table of Note 13 to the Consolidated Financial Statements. ASU 2015-16 "Business Combinations (Topic 805)" This standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2016-09 "Compensation - Stock Compensation (Topic 718)" This standard simplifies several aspects of the accounting for share-based payment transactions, but may increase volatility in income tax expense. All excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the income statement. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period, subject to normal valuation allowance considerations. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. Please refer to Note 20 of the Consolidated Financial Statements for a detailed explanation of the cumulative effect of adoption recognized on January 1, 2016 and the impact to our Consolidated Statements of Earnings. ASU 2016-15 "Statement of Cash Flows (Topic 230)" This standard addresses the presentation and classification of eight specific cash flow issues, including debt prepayment and extinguishment costs. Entities will adopt the standard using a retrospective method. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2016-18 "Statement of Cash Flows (Topic 230)" This standard requires that a statement of cash flows explain the change in the total of cash, cash equivalents and amounts generally described as restricted cash. Entities will adopt the standard using a retrospective method. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements.

DERIVATIVE FINANCIAL INSTRUMENTS	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with counterparties generally contain right of offset provisions. These provisions effectively reduce the Company’s exposure to credit risk in situations where the Company has gain and loss positions outstanding with a single counterparty. It is the Company’s policy to offset on the Consolidated Balance Sheets the amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master netting agreement. As of December 31, 2016 and 2015 , the Company did not have any amounts on deposit with any of its counterparties, nor did any of its counterparties have any amounts on deposit with the Company. The following table presents the fair value and respective location of derivatives and hedging instruments on the Consolidated Balance Sheets (in millions): Fair Value at Location December 31, 2016 December 31, 2015 Derivative assets designated as hedging instruments: Net investment hedges Cross currency swaps Other current assets $ 4 $ 4 Cross currency swaps Other non current assets $ 6 $ 6 Amount of gain recognized in OCI (effective portion) OCI $ 18 $ 14 Fair value hedges Interest rate swaps Other non current assets $ — $ 4 Cash flow hedges: Natural gas forward swaps Other current assets $ 4 $ — Amount of gain recognized in OCI (effective portion) OCI $ 4 $ — Derivative liabilities designated as hedging instruments: Cash flow hedges: Natural gas forward swaps Accounts payable and accrued liabilities $ — $ 5 Amount of loss recognized in OCI related to natural gas forward swaps (effective portion) OCI $ — $ 5 Amount of loss recognized in OCI related to foreign exchange contracts (effective portion) OCI $ — $ 1 Amount of loss recognized in OCI related to treasury interest rate lock (effective portion) OCI $ 1 $ — Derivative assets not designated as hedging instruments: Natural gas forward swaps Other current assets $ 1 $ — Foreign exchange contracts Other current assets $ 1 $ — Derivative liabilities not designated as hedging instruments: Natural gas forward swaps Accounts payable and accrued liabilities $ — $ 1 Foreign exchange contracts Accounts payable and accrued liabilities $ 2 $ — The following table presents the notional of derivatives and hedging instruments on the Consolidated Balance Sheets (in millions): Notional Unit of Measure December 31, 2016 Net investment hedges Cross currency swaps U.S. Dollars $ 250 Cash flow hedges: Natural gas forward swaps U.S. indices MMBtu 7 Natural gas forward swaps European indices MMBtu (equivalent) 1 The Company had notional amounts for derivative hedging instruments related to non-designated foreign currency exposure in U.S. Dollars primarily relative to Brazilian Real, Chinese Yuan, Indian Rupee, Japanese Yen, and South Korean Won for $106 million . In addition the Company had notional amounts for derivative hedging instruments related to non-designated foreign currency exposure in European Euro primarily relative to British Pounds and Russian Rubles for $28 million .

Cash Flow Hedges The Company uses forward and swap contracts, which qualify as cash flow hedges, to manage forecasted exposure to natural gas and electricity prices. The effective portion of the change in the fair value of cash flow hedges is deferred in accumulated OCI on the Consolidated Balance Sheets and is subsequently recognized in cost of sales on the Consolidated Statements of Earnings for commodity hedges, when the hedged item impacts earnings. Changes in the fair value of derivative assets and liabilities designated as hedging instruments are included in the Other non-cash line within operating activities on the Consolidated Statements of Cash Flows. Any portion of the change in fair value of derivatives designated as hedging instruments that is determined to be ineffective is recorded in other expenses, net on the Consolidated Statements of Earnings. The Company currently has natural gas derivatives designated as hedging instruments that mature within 15 months . The Company’s policy for natural gas exposures is to hedge up to 75 percent of its total forecasted exposures for the next two months, up to 60 percent of its total forecasted exposures for the following four months, and lesser amounts for the remaining periods. The Company's policy for electricity exposures is to hedge up to 75 percent of its total forecasted exposures for the current calendar year and up to 65 percent of its total forecasted exposures for the first calendar year forward. Based on market conditions, approved variation from the standard policy may occur. The Company performs an analysis for effectiveness of its derivatives designated as hedging instruments at the end of each quarter based on the terms of the contract and the underlying item being hedged. In June 2016, the Company entered into a $200 million forward U.S. Treasury rate lock agreement to manage the U.S. Treasury portion of its interest rate risk associated with the anticipated issuance of 10 fixed rate senior notes in 2016. The locked fixed rate of this agreement was 1.633% . In July 2016, the Company entered into a similar forward U.S. Treasury rate lock agreement for $100 million at a locked fixed rate of 1.490% . The Company designated these outstanding forward U.S. Treasury rate lock agreements, which would have expired on September 15, 2016, as cash flow hedges. The Company paid $1 million to settle these agreements in August 2016 upon issuance of its 2026 senior notes, effectively locking in the U.S. Treasury fixed interest rate in effect at the time the agreements were initiated. The $1 million fair value of these agreements will be amortized over the remaining life of the senior notes as a component of interest expense. Hedge ineffectiveness for these agreements was less than $1 million. Please refer to Note 12 of the Consolidated Financial Statements for further information on the issuance of the 2026 senior notes. As of December 31, 2016 , $4 million of loss included in accumulated OCI on the Consolidated Balance Sheets relate to contracts that will impact earnings during the next 12 months. Transactions and events that are expected to occur over the next 12 months that will necessitate recognizing these deferred gains include the recognition of the hedged item through earnings. Fair Value Hedges In the first quarter of 2016, the Company terminated the interest rate swaps designated to hedge a portion of its 4.20% senior notes due 2022 and received net settlement proceeds totaling $8 million . The swaps were carried at fair value and recorded as other assets or liabilities, with the offset to long-term debt on the Consolidated Balance Sheets. Changes in the fair value of these swaps and that of the related debt were recorded in Interest expense, net on the Consolidated Statements of Earnings. These proceeds were classified as cash provided by operating activities in the Consolidated Statements of Cash Flows. The $8 million fair value adjustment to debt will be amortized through 2022 as a reduction to interest expense in conjunction with the maturity date of the Company's 4.20% senior notes due 2022. Net Investment Hedges The Company uses cross currency forward contracts to hedge a portion of the net investment in foreign subsidiaries against fluctuations in foreign exchange rates. For derivative instruments that are designated and qualify as hedges of net investments in foreign operations, settlements and changes in fair values of the derivative instruments are recognized in Currency translation adjustment, a component of Accumulated OCI, to offset the changes in the values of the net investments being hedged. Any portion of net investment hedges that is determined to be ineffective is recorded in Other expenses, net on the Consolidated Statements of Earnings. Other Derivatives The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in other expenses, net on the Consolidated Statements of Earnings.

The Company expects the ongoing amortization expense for amortizable intangible assets to be $27 million in each of the next five fiscal years. The Company’s future cash flows are not materially impacted by its ability to extend or renew agreements related to its amortizable intangible assets. These costs are reported in Other expenses, net on the Consolidated Statements of Earnings. Goodwill and Indefinite-Lived Intangible Assets During 2016, goodwill increased by $173 million as a result of the acquisition of Interwrap Holdings, Inc. ("Interwrap"); see Note 7 for more details of this acquisition. The Company tests goodwill and indefinite-lived intangible assets for impairment as of October 1 each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The annual test performed in 2016 resulted in no impairment of goodwill.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS On April 21, 2016, the Company acquired all outstanding shares of InterWrap, a leading manufacturer of roofing underlayment and packaging materials, for approximately $452 million , net of cash acquired. This acquisition expands the Company’s position in roofing components, strengthens the Company’s capabilities to support the conversion from organic to synthetic underlayment and accelerates its growth in the roofing components market. Interwrap's operating results have been included in the Roofing segment of the Company's Consolidated Financial Statements since the date of the acquisition. During the year ended December 31, 2016, the Company recorded certain immaterial measurement period adjustments to the purchase price allocation which are reflected in the value of goodwill noted below. The Company's acquisition of InterWrap included intangible assets valued at $163 million . These assets consist of indefinite-lived trademarks of $59 million , customer relationships of $81 million with an estimated weighted average life of 25 years, and technology, including patented technology, of $23 million with an estimated weighted average useful life of 14 years. Goodwill is valued at approximately $173 million with $20 million expected to be tax-deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the InterWrap acquisition and will support continued market growth through conversion from organic to synthetic underlayment, as well as provide growth opportunities in lumber and metal packaging. Please refer to Note 5 for further information on these intangible assets. The acquisition also included inventory valued at $72 million . During the year ended December 31, 2016, the Consolidated Statements of Earnings included $182 million in Net sales attributable to the acquisition and a $10 million charge related to inventory fair value step-up in Cost of sales. The pro forma effect of this acquisition on earnings and revenue was not material. On July 26, 2016, the Company and Ahlstrom agreed to terminate the previously announced purchase agreement of the non-wovens and fabrics business of Ahlstrom due to challenges associated with obtaining regulatory clearance in Germany. In connection with the termination of the purchase agreement, the Company paid Ahlstrom a termination fee of approximately $3 million . The expense was included within Other expenses, net in the Consolidated Statements of Earnings in the third quarter of 2016.

During 2016, the Company recorded $18 million of charges for this restructuring, primarily comprised of accelerated depreciation. The Company expects to incur an immaterial amount of exit costs related to this restructuring in 2017. InterWrap Acquisition-Related Restructuring Costs Following the acquisition of InterWrap into the Company's Roofing segment, the Company took actions to realize expected synergies from the newly acquired operations. During 2016, the Company recorded $3 million of accelerated depreciation charges for this restructuring. The Company expects to incur an immaterial amount of exit costs related to this restructuring in 2017. 2014 Cost Reduction Actions During 2014, the Company took actions to reduce costs throughout its global Composites network, mainly through the decisions to close a facility in Japan and optimize a facility in Canada, in addition to other cost reduction actions. The Company also took actions in 2014 to streamline its management structure and reduce costs, resulting in the elimination of the Building Materials Group organizational structure. In 2016, the Company incurred $7 million of charges for this restructuring, c omprised of facility optimization costs, revision of estimated severance costs and a pension-related charge.

Interest on the notes is payable semiannually in arrears on February 15 and August 15 each year, beginning on February 15, 2017. A portion of the proceeds from these notes was used to redeem $158 million of our 2016 senior notes, together with a $2 million make whole call payment and $3 million of accrued interest. In connection with the redemption, the Company recognized a $1 million loss on extinguishment of debt, inclusive of the remaining unamortized financing fees, discount and interest rate swap fair value adjustment. The remaining proceeds were used to pay down portions of our Receivables Securitization Facility and for general corporate purposes. The Company issued $400 million of 2024 senior notes on November 12, 2014. Interest on the notes is payable semiannually in arrears on June 1 and December 1 each year, beginning on June 1, 2015. A portion of the proceeds from these notes was used to repay $242 million of our 2016 senior notes and $105 million of our 2019 senior notes. The remaining proceeds were used to pay down our Senior Revolving Credit Facility (as defined below), finance general working capital needs, and for general corporate purposes. The Company issued $600 million of 2022 senior notes on October 17, 2012. Interest on the notes is payable semiannually in arrears on June 15 and December 15 each year, beginning on June 15, 2013. The proceeds of these notes were used to refinance $250 million of our 2016 senior notes and $100 million of our 2019 senior notes and pay down our Senior Revolving Credit Facility. The Company issued $350 million of 2019 senior notes on June 3, 2009. On October 31, 2006, the Company issued $650 million of 2016 senior notes and $540 million of 2036 senior notes. The proceeds of these notes were used to pay certain unsecured and administrative claims, finance general working capital needs and for general corporate purposes. As of December 31, 2015, the $158 million in outstanding principal related to the 2016 senior notes was recorded in Long-term debt - current portion on the Consolidated Balance Sheets, along with with $2 million net in associated unamortized financing fees, discount, and interest rate swap basis adjustment. These senior notes were fully repaid in the third quarter of 2016, with a portion of the proceeds from the issuance of our 2026 senior notes. Collectively, the notes above are referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company. The Senior Notes are fully and unconditionally guaranteed by each of the Company’s current and future domestic subsidiaries that are a borrower or guarantor under the Company’s Credit Agreement (as defined below). The guarantees are unsecured and rank equally in right of payment with all other existing and future senior unsecured indebtedness of the guarantors. The guarantees are effectively subordinated to existing and future secured debt of the guarantors to the extent of the assets securing that indebtedness. The Company has the option to redeem all or part of the Senior Notes at any time at a “make-whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of December 31, 2016 . In the fourth quarter of 2011, the Company terminated all interest rate swaps designated to hedge a portion of the 6.5% senior notes due 2016. The swaps were carried at fair value and recorded as other assets or liabilities, with a fair value adjustment to long-term debt on the Consolidated Balance Sheets. The fair value adjustment to debt was fully amortized in the third quarter of 2016 as a reduction to interest expense in conjunction with the extinguishment of the 2016 senior notes in the same quarter. In the first quarter of 2016, the Company terminated the existing interest rate swaps designated to hedge a portion of the 4.20% senior notes due 2022 and received net settlement proceeds totaling $8 million. The swaps were carried at fair value and recorded as other assets or liabilities, with a fair value adjustment to long-term debt on the Consolidated Balance Sheets. The proceeds are classified as cash provided by operating activities in the Consolidated Statements of Cash Flows. The $8 million fair value adjustment to debt will be amortized through 2022 as a reduction to interest expense in conjunction with the maturity date of the 2022 senior notes. Senior Credit Facilities The Company has an $800 million multi-currency senior revolving credit facility that has been amended from time to time (the "Senior Revolving Credit Facility") with a maturity date in November 2020 and uncommitted incremental loans permitted under the facility of $600 million . The Company obtained commitments for $300 million of the $600 million of permitted incremental term loans in March 2016. As discussed further below, the Company subsequently borrowed $300 million on this commitment in April 2016 and fully repaid the $300 million of borrowings in September 2016. The Company may obtain new commitments for incremental term loans up to $600 million as permitted under the Senior Revolving Credit Facility. No subsequent amendments had an impact on current liquidity terms. The Company removed certain subsidiaries from the list of named guarantors in May 2016. As of September 30, 2016, the Company added additional subsidiaries to the list of named guarantors. The Senior Revolving Credit Facility includes both borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate or LIBOR plus a spread. The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a senior unsecured credit agreement. The Company was in compliance with these covenants as of December 31, 2016 . As of December 31, 2016, the Company had no borrowings on its Senior Revolving Credit Facility, $9 million of outstanding letters of credit, and had $791 million available under the facility. Term Loan During the first quarter of 2016, the Company obtained a Term Loan commitment for $300 million (the "Term Loan"), as allowed under its existing Senior Revolving Credit Facility. The Term Loan was a partially amortizing loan that required quarterly principal repayments, with a balloon repayment due in November 2020 for any outstanding borrowings. The Term Loan contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio, that the Company believes are usual and customary for a senior unsecured credit agreement. On April 20, 2016, the Company borrowed the $300 million available on the Term Loan at LIBOR plus a spread. These borrowings were used, in addition to borrowings on the Receivables Securitization Facility, to fund the acquisition of InterWrap. Please see Note 7 of the Notes to Consolidated Financial Statements for more information on this acquisition. In the third quarter of 2016, the Company repaid all outstanding borrowings on the Term Loan. Receivables Securitization Facility Included in long-term debt on the Consolidated Balance Sheets are amounts outstanding under a Receivables Purchase Agreement (the “RPA”) that are accounted for as secured borrowings in accordance with ASC 860, Accounting for Transfers and Servicing. Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $250 million RPA with certain financial institutions. The securitization facility was amended in January of 2015 to extend its maturity to January 2018. The Company has the ability to borrow at the lenders' cost of funds, which approximates A-1/P-1 commercial paper rates, plus a fixed spread. As of December 31, 2016, the Company had no borrowings on its Receivables Securitization Facility, $2 million of outstanding letters of credit, and had $248 million available on the facility. The Receivables Securitization Facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a securitization facility. The Company was in compliance with these covenants as of December 31, 2016 . Owens Corning Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers party to the RPA. Owens Corning Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of Owens Corning Receivables LLC’s assets prior to any assets or value in Owens Corning Receivables LLC becoming available to Owens Corning Receivables LLC’s equity holders. The assets of Owens Corning Receivables LLC are not available to pay creditors of the Company or any other affiliates of the Company or Owens Corning Sales, LLC. Debt Maturities The aggregate maturities for all long-term debt issues for each of the five years following December 31, 2016 and thereafter are presented in the table below (in millions). The maturities stated below are the aggregate par amounts of the outstanding senior notes and capital lease payments. Period Maturities 2017 $ 6 2018 6 2019 150 2020 6 2021 6 2022 and beyond 1,964 Total $ 2,138 Short-Term Debt At December 31, 2016 and December 31, 2015 , short-term borrowings were less than $1 million and $6 million , respectively. The short-term borrowings for both periods consisted of various operating lines of credit and working capital facilities. Certain of these borrowings are collateralized by receivables, inventories or property. The borrowing facilities are typically for one -year renewable terms. The weighted average interest rate on all short-term borrowings was approximately 5.4% for December 31, 2016 and 4.5% for December 31, 2015 .

PENSION PLANS

PENSION PLANS	12 Months Ended

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
PENSION PLANS	PENSION PLANS The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. In our U.S. plan, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants. In all of our Non-U.S plans, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits. During the second quarter of 2016, the Company recorded a $6 million pension curtailment gain related to 2015. This benefit was recorded in Cost of sales on the Consolidated Statements of Earnings and reduced General corporate expense and other in our Corporate, Other and Eliminations category. The effect of this error was not material to the current or any previously issued financial statements. The following tables provide a reconciliation of the change in the projected benefit obligation, the change in plan assets and the net amount recognized in the Consolidated Balance Sheets (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Projected Benefit Obligation Benefit obligation at beginning of period $ 1,092 $ 485 $ 1,577 $ 1,193 $ 571 $ 1,764 Service cost 7 3 10 8 4 12 Interest cost 44 18 62 44 19 63 Actuarial (gain) loss 5 75 80 (50 ) (19 ) (69 ) Currency (gain) — (46 ) (46 ) — (55 ) (55 ) Benefits paid (82 ) (21 ) (103 ) (101 ) (21 ) (122 ) Settlements/curtailments — (7 ) (7 ) — (7 ) (7 ) Other — 5 5 (2 ) (7 ) (9 ) Benefit obligation at end of period $ 1,066 $ 512 $ 1,578 $ 1,092 $ 485 $ 1,577 December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Plan Assets Fair value of assets at beginning of period $ 806 $ 379 $ 1,185 $ 883 $ 437 $ 1,320 Actual return on plan assets 47 53 100 (23 ) 2 (21 ) Currency (loss) — (29 ) (29 ) — (46 ) (46 ) Company contributions 50 13 63 47 13 60 Benefits paid (82 ) (21 ) (103 ) (101 ) (21 ) (122 ) Settlements/curtailments — (4 ) (4 ) — (7 ) (7 ) Other 1 2 3 — 1 1 Fair value of assets at end of period $ 822 $ 393 $ 1,215 $ 806 $ 379 $ 1,185 Funded status $ (244 ) $ (119 ) $ (363 ) $ (286 ) $ (106 ) $ (392 ) December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Amounts Recognized in the Consolidated Balance Sheets Prepaid pension cost $ — $ 5 $ 5 $ — $ 6 $ 6 Accrued pension cost – current — (1 ) (1 ) — (1 ) (1 ) Accrued pension cost – non-current (244 ) (123 ) (367 ) (286 ) (111 ) (397 ) Net amount recognized $ (244 ) $ (119 ) $ (363 ) $ (286 ) $ (106 ) $ (392 ) Amounts Recorded in Accumulated OCI Net actuarial loss $ (433 ) $ (129 ) $ (562 ) $ (431 ) $ (96 ) $ (527 ) The following table presents information about the projected benefit obligation, accumulated benefit obligation (“ABO”) and plan assets of the Company’s pension plans (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Plans with ABO in excess of fair value of plan assets: Projected benefit obligation $ 1,066 $ 310 $ 1,376 $ 1,092 $ 314 $ 1,406 Accumulated benefit obligation $ 1,066 $ 305 $ 1,371 $ 1,092 $ 311 $ 1,403 Fair value of plan assets $ 822 $ 192 $ 1,014 $ 806 $ 206 $ 1,012 Plans with fair value of assets in excess of ABO: Projected benefit obligation $ — $ 202 $ 202 $ — $ 171 $ 171 Accumulated benefit obligation $ — $ 187 $ 187 $ — $ 156 $ 156 Fair value of plan assets $ — $ 201 $ 201 $ — $ 173 $ 173 Total projected benefit obligation $ 1,066 $ 512 $ 1,578 $ 1,092 $ 485 $ 1,577 Total accumulated benefit obligation $ 1,066 $ 492 $ 1,558 $ 1,092 $ 467 $ 1,559 Total plan assets $ 822 $ 393 $ 1,215 $ 806 $ 379 $ 1,185 Weighted-Average Assumptions Used to Determine Benefit Obligation The following table presents weighted average assumptions used to determine benefit obligations at the measurement dates noted: December 31, 2016 2015 United States Plans Discount rate 3.95 % 4.20 % Expected return on plan assets 6.75 % 7.00 % Non-United States Plans Discount rate 3.14 % 3.88 % Expected return on plan assets 5.92 % 6.23 % Rate of compensation increase 4.25 % 3.97 % Components of Net Periodic Pension Cost The following table presents the components of net periodic pension cost for the periods noted (in millions): Twelve Months Ended December 31, 2016 2015 2014 Service cost $ 10 $ 12 $ 13 Interest cost 62 63 71 Expected return on plan assets (81 ) (84 ) (84 ) Amortization of actuarial loss 16 18 11 Settlement/curtailment (6 ) (3 ) — Other 2 1 — Net periodic benefit cost $ 3 $ 7 $ 11 Weighted-Average Assumptions Used to Determine Net Periodic Pension Cost The following table presents weighted-average assumptions used to determine net periodic pension costs for the periods noted: Twelve Months Ended December 31, 2016 2015 2014 United States Plans Discount rate 4.20 % 3.85 % 4.65 % Expected return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase N/A (a) N/A (a) N/A (a) Non-United States Plans Discount rate 3.88 % 3.60 % 4.45 % Expected return on plan assets 6.23 % 6.27 % 6.38 % Rate of compensation increase 3.97 % 4.01 % 3.94 % (a) Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010. The expected return on plan assets assumption is derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model is used to develop an expected range of returns on plan investments over a 20 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. The result is then rounded down to the nearest 25 basis points. Accumulated Other Comprehensive Earnings (Deficit) Of the $(562) million balance in OCI, $19 million is expected to be recognized as net periodic pension cost during 2017 . Items Measured at Fair Value The Company classifies and discloses pension plan assets in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. Plan Assets The tables in this section show pension plan asset fair values and fair value leveling information. The assets are categorized into one of the three levels of the fair value hierarchy or are not subject to leveling. Following our adoption of ASU 2015-07 on January 1, 2016, the assets that are not subject to leveling are investments that are valued using the net asset value per share (or its equivalent) practical expedient. We have applied this approach retrospectively to the 2015 tables for comparability. The fair value amounts presented in the "not subject to leveling" column are intended to permit reconciliation of the fair value hierarchy tables to the amounts presented for total pension plan assets. The following table summarizes the fair values and applicable fair value hierarchy levels of United States pension plan assets (in millions): December 31, 2016 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ 69 $ — $ — $ 50 $ 119 Domestic passive index — — — 71 71 International actively managed 81 — — 33 114 International passive index — — — 26 26 Fixed income and cash equivalents — Cash — — — — — Short-term debt — — — 26 26 Corporate bonds 200 25 — 28 253 Government debt 86 — — — 86 Real estate investment trusts 24 — — — 24 Absolute return strategies — — — 52 52 Real assets — — — 51 51 Total United States plan assets $ 460 $ 25 $ — $ 337 $ 822 December 31, 2015 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ 85 $ — $ — $ 36 $ 121 Domestic passive index — — — 51 51 International actively managed 79 — — 31 110 International passive index — — — 23 23 Fixed income and cash equivalents — Cash — — — 1 1 Short-term debt — — — 33 33 Corporate bonds 204 27 — 25 256 Government debt 88 — — — 88 Real estate investment trusts 25 — — — 25 Absolute return strategies — — — 52 52 Real assets — — — 46 46 Total United States plan assets $ 481 $ 27 $ — $ 298 $ 806 The following table summarizes the fair values and applicable fair value hierarchy levels of non-United States pension plan assets (in millions): December 31, 2016 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ — $ 1 $ — $ 28 $ 29 Domestic passive index — — — 1 1 International actively managed — 2 — 58 60 International passive index — — — 3 3 Fixed income and cash equivalents — Cash and cash equivalents — 36 — 1 37 Corporate bonds — 5 — 163 168 Government Debt — — — — — Absolute return strategies — — — 95 95 Total non-United States plan assets $ — $ 44 $ — $ 349 $ 393 December 31, 2015 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ — $ 2 $ — $ 22 $ 24 Domestic passive index — — — 1 1 International actively managed 39 5 — 18 62 International passive index — — — 25 25 Fixed income and cash equivalents — Cash and cash equivalents — 24 — 2 26 Corporate bonds — 11 — 138 149 Government Debt — — — — — Absolute return strategies — — — 92 92 Total non-United States plan assets $ 39 $ 42 $ — $ 298 $ 379 Investment Strategy The current investment policy for the United States pension plan is to have 38% of assets invested in equities, 3% in real estate, 6% in real assets, 47% in intermediate and long-term fixed income securities and 6% in absolute return strategies. Assets are rebalanced quarterly to conform to policy tolerances. The Company actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset mix for the non-United States pension plans varies by location and is based on projected benefit obligation and market dynamics. Estimated Future Benefit Payments The following table shows estimated future benefit payments from the Company’s pension plans (in millions): Year Estimated Benefit Payments 2017 $ 100 2018 $ 96 2019 $ 98 2020 $ 97 2021 $ 94 2022-2026 $ 460 Contributions Owens Corning expects to contribute $50 million in cash to the United States pension plan during 2017 and another $9 million to non-United States plans. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements. Defined Contribution Plans The Company sponsors two defined contribution plans which are available to substantially all United States employees. The Company matches a percentage of employee contributions up to a maximum level and contributes up to 2% of an employee’s wages regardless of employee contributions. The Company recognized expense of $38 million , $33 million and $34 million during the years ended December 31, 2016 , 2015 and 2014 , respectively, related to these plans. POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement. Salaried employees hired on or before December 31, 2005 become eligible to participate in the United States health care plans upon retirement if they have accumulated 10 years of service after age 45 , 48 or 50 , depending on the category of employee. For employees hired after December 31, 2005, the Company does not provide subsidized retiree health care. Some of the plans are contributory, with some retiree contributions adjusted annually. The Company has reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements. The Company implemented an Employee Group Waiver Plan ("EGWP") effective January 1, 2013 to manage its prescription drug benefits for certain retiree groups. The Company also negotiated with certain unionized employees to increase the eligibility age for retiree medical benefits and to eliminate the post- 65 retiree reimbursement account benefit for employees retiring on or after January 1, 2014. The following table provides a reconciliation of the change in the projected benefit obligation and the net amount recognized in the Consolidated Balance Sheets for the years ended December 31, 2016 and 2015 (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Projected Benefit Obligation Benefit obligation at beginning of period $ 230 $ 13 $ 243 $ 238 $ 16 $ 254 Service cost 2 — 2 2 — 2 Interest cost 9 — 9 8 1 9 Actuarial gain (15 ) — (15 ) (3 ) — (3 ) Currency gain — — — — (2 ) (2 ) Plan amendments — — — — — — Benefits paid (14 ) (1 ) (15 ) (15 ) (1 ) (16 ) Other — 1 1 — (1 ) (1 ) Benefit obligation at end of period $ 212 $ 13 $ 225 $ 230 $ 13 $ 243 Funded status $ (212 ) $ (13 ) $ (225 ) $ (230 ) $ (13 ) $ (243 ) Amounts Recognized in the Consolidated Balance Sheets Accrued benefit obligation – current $ (17 ) $ (1 ) $ (18 ) $ (17 ) $ (1 ) $ (18 ) Accrued benefit obligation – non-current (195 ) (12 ) (207 ) (213 ) (12 ) (225 ) Net amount recognized $ (212 ) $ (13 ) $ (225 ) $ (230 ) $ (13 ) $ (243 ) Amounts Recorded in Accumulated OCI Net actuarial gain $ (19 ) $ (4 ) $ (23 ) $ (4 ) $ (4 ) $ (8 ) Net prior service credit (12 ) — (12 ) (17 ) — (17 ) Net amount recognized $ (31 ) $ (4 ) $ (35 ) $ (21 ) $ (4 ) $ (25 ) Weighted-Average Assumptions Used to Determine Benefit Obligations The following table presents the discount rates used to determine the benefit obligations: December 31, 2016 2015 United States plans 3.80 % 4.00 % Non-United States plans 3.55 % 3.80 % Components of Net Periodic Postretirement Benefit Cost The following table presents the components of net periodic postretirement benefit cost (in millions): Twelve Months Ended December 31, 2016 2015 2014 Service cost $ 2 $ 2 $ 2 Interest cost 9 9 10 Amortization of prior service cost (4 ) (4 ) (4 ) Amortization of actuarial gain (1 ) (1 ) (2 ) Other 1 1 — Net periodic postretirement benefit cost $ 7 $ 7 $ 6 Weighted-Average Assumptions Used to Determine Net Periodic Postretirement Benefit Cost The following table presents the discount rates used to determine net periodic postretirement benefit cost: Twelve Months Ended December 31, 2016 2015 2014 United States plans 4.00 % 3.70 % 4.35 % Non-United States plans 3.80 % 3.70 % 4.45 % The following table presents health care cost trend rates used to determine net periodic postretirement benefit cost, as well as information regarding the ultimate rate and the year in which the ultimate rate is reached: Twelve Months Ended December 31, 2016 2015 2014 United States plans Initial rate at end of year 6.78 % 7.00 % 7.00 % Ultimate rate 5.00 % 5.00 % 5.00 % Year in which ultimate rate is reached 2025 2025 2024 Non-United States plans Initial rate at end of year 5.07 % 5.25 % 5.43 % Ultimate rate 4.70 % 4.70 % 4.70 % Year in which ultimate rate is reached 2019 2019 2019 The health care cost trend rate assumption can have a significant effect on the amounts reported.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS	PENSION PLANS The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. In our U.S. plan, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants. In all of our Non-U.S plans, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits. During the second quarter of 2016, the Company recorded a $6 million pension curtailment gain related to 2015. This benefit was recorded in Cost of sales on the Consolidated Statements of Earnings and reduced General corporate expense and other in our Corporate, Other and Eliminations category. The effect of this error was not material to the current or any previously issued financial statements. The following tables provide a reconciliation of the change in the projected benefit obligation, the change in plan assets and the net amount recognized in the Consolidated Balance Sheets (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Projected Benefit Obligation Benefit obligation at beginning of period $ 1,092 $ 485 $ 1,577 $ 1,193 $ 571 $ 1,764 Service cost 7 3 10 8 4 12 Interest cost 44 18 62 44 19 63 Actuarial (gain) loss 5 75 80 (50 ) (19 ) (69 ) Currency (gain) — (46 ) (46 ) — (55 ) (55 ) Benefits paid (82 ) (21 ) (103 ) (101 ) (21 ) (122 ) Settlements/curtailments — (7 ) (7 ) — (7 ) (7 ) Other — 5 5 (2 ) (7 ) (9 ) Benefit obligation at end of period $ 1,066 $ 512 $ 1,578 $ 1,092 $ 485 $ 1,577 December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Plan Assets Fair value of assets at beginning of period $ 806 $ 379 $ 1,185 $ 883 $ 437 $ 1,320 Actual return on plan assets 47 53 100 (23 ) 2 (21 ) Currency (loss) — (29 ) (29 ) — (46 ) (46 ) Company contributions 50 13 63 47 13 60 Benefits paid (82 ) (21 ) (103 ) (101 ) (21 ) (122 ) Settlements/curtailments — (4 ) (4 ) — (7 ) (7 ) Other 1 2 3 — 1 1 Fair value of assets at end of period $ 822 $ 393 $ 1,215 $ 806 $ 379 $ 1,185 Funded status $ (244 ) $ (119 ) $ (363 ) $ (286 ) $ (106 ) $ (392 ) December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Amounts Recognized in the Consolidated Balance Sheets Prepaid pension cost $ — $ 5 $ 5 $ — $ 6 $ 6 Accrued pension cost – current — (1 ) (1 ) — (1 ) (1 ) Accrued pension cost – non-current (244 ) (123 ) (367 ) (286 ) (111 ) (397 ) Net amount recognized $ (244 ) $ (119 ) $ (363 ) $ (286 ) $ (106 ) $ (392 ) Amounts Recorded in Accumulated OCI Net actuarial loss $ (433 ) $ (129 ) $ (562 ) $ (431 ) $ (96 ) $ (527 ) The following table presents information about the projected benefit obligation, accumulated benefit obligation (“ABO”) and plan assets of the Company’s pension plans (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Plans with ABO in excess of fair value of plan assets: Projected benefit obligation $ 1,066 $ 310 $ 1,376 $ 1,092 $ 314 $ 1,406 Accumulated benefit obligation $ 1,066 $ 305 $ 1,371 $ 1,092 $ 311 $ 1,403 Fair value of plan assets $ 822 $ 192 $ 1,014 $ 806 $ 206 $ 1,012 Plans with fair value of assets in excess of ABO: Projected benefit obligation $ — $ 202 $ 202 $ — $ 171 $ 171 Accumulated benefit obligation $ — $ 187 $ 187 $ — $ 156 $ 156 Fair value of plan assets $ — $ 201 $ 201 $ — $ 173 $ 173 Total projected benefit obligation $ 1,066 $ 512 $ 1,578 $ 1,092 $ 485 $ 1,577 Total accumulated benefit obligation $ 1,066 $ 492 $ 1,558 $ 1,092 $ 467 $ 1,559 Total plan assets $ 822 $ 393 $ 1,215 $ 806 $ 379 $ 1,185 Weighted-Average Assumptions Used to Determine Benefit Obligation The following table presents weighted average assumptions used to determine benefit obligations at the measurement dates noted: December 31, 2016 2015 United States Plans Discount rate 3.95 % 4.20 % Expected return on plan assets 6.75 % 7.00 % Non-United States Plans Discount rate 3.14 % 3.88 % Expected return on plan assets 5.92 % 6.23 % Rate of compensation increase 4.25 % 3.97 % Components of Net Periodic Pension Cost The following table presents the components of net periodic pension cost for the periods noted (in millions): Twelve Months Ended December 31, 2016 2015 2014 Service cost $ 10 $ 12 $ 13 Interest cost 62 63 71 Expected return on plan assets (81 ) (84 ) (84 ) Amortization of actuarial loss 16 18 11 Settlement/curtailment (6 ) (3 ) — Other 2 1 — Net periodic benefit cost $ 3 $ 7 $ 11 Weighted-Average Assumptions Used to Determine Net Periodic Pension Cost The following table presents weighted-average assumptions used to determine net periodic pension costs for the periods noted: Twelve Months Ended December 31, 2016 2015 2014 United States Plans Discount rate 4.20 % 3.85 % 4.65 % Expected return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase N/A (a) N/A (a) N/A (a) Non-United States Plans Discount rate 3.88 % 3.60 % 4.45 % Expected return on plan assets 6.23 % 6.27 % 6.38 % Rate of compensation increase 3.97 % 4.01 % 3.94 % (a) Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010. The expected return on plan assets assumption is derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model is used to develop an expected range of returns on plan investments over a 20 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. The result is then rounded down to the nearest 25 basis points. Accumulated Other Comprehensive Earnings (Deficit) Of the $(562) million balance in OCI, $19 million is expected to be recognized as net periodic pension cost during 2017 . Items Measured at Fair Value The Company classifies and discloses pension plan assets in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. Plan Assets The tables in this section show pension plan asset fair values and fair value leveling information. The assets are categorized into one of the three levels of the fair value hierarchy or are not subject to leveling. Following our adoption of ASU 2015-07 on January 1, 2016, the assets that are not subject to leveling are investments that are valued using the net asset value per share (or its equivalent) practical expedient. We have applied this approach retrospectively to the 2015 tables for comparability. The fair value amounts presented in the "not subject to leveling" column are intended to permit reconciliation of the fair value hierarchy tables to the amounts presented for total pension plan assets. The following table summarizes the fair values and applicable fair value hierarchy levels of United States pension plan assets (in millions): December 31, 2016 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ 69 $ — $ — $ 50 $ 119 Domestic passive index — — — 71 71 International actively managed 81 — — 33 114 International passive index — — — 26 26 Fixed income and cash equivalents — Cash — — — — — Short-term debt — — — 26 26 Corporate bonds 200 25 — 28 253 Government debt 86 — — — 86 Real estate investment trusts 24 — — — 24 Absolute return strategies — — — 52 52 Real assets — — — 51 51 Total United States plan assets $ 460 $ 25 $ — $ 337 $ 822 December 31, 2015 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ 85 $ — $ — $ 36 $ 121 Domestic passive index — — — 51 51 International actively managed 79 — — 31 110 International passive index — — — 23 23 Fixed income and cash equivalents — Cash — — — 1 1 Short-term debt — — — 33 33 Corporate bonds 204 27 — 25 256 Government debt 88 — — — 88 Real estate investment trusts 25 — — — 25 Absolute return strategies — — — 52 52 Real assets — — — 46 46 Total United States plan assets $ 481 $ 27 $ — $ 298 $ 806 The following table summarizes the fair values and applicable fair value hierarchy levels of non-United States pension plan assets (in millions): December 31, 2016 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ — $ 1 $ — $ 28 $ 29 Domestic passive index — — — 1 1 International actively managed — 2 — 58 60 International passive index — — — 3 3 Fixed income and cash equivalents — Cash and cash equivalents — 36 — 1 37 Corporate bonds — 5 — 163 168 Government Debt — — — — — Absolute return strategies — — — 95 95 Total non-United States plan assets $ — $ 44 $ — $ 349 $ 393 December 31, 2015 Asset Category Level 1 Level 2 Level 3 Not subject to leveling Total Equity Domestic actively managed $ — $ 2 $ — $ 22 $ 24 Domestic passive index — — — 1 1 International actively managed 39 5 — 18 62 International passive index — — — 25 25 Fixed income and cash equivalents — Cash and cash equivalents — 24 — 2 26 Corporate bonds — 11 — 138 149 Government Debt — — — — — Absolute return strategies — — — 92 92 Total non-United States plan assets $ 39 $ 42 $ — $ 298 $ 379 Investment Strategy The current investment policy for the United States pension plan is to have 38% of assets invested in equities, 3% in real estate, 6% in real assets, 47% in intermediate and long-term fixed income securities and 6% in absolute return strategies. Assets are rebalanced quarterly to conform to policy tolerances. The Company actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset mix for the non-United States pension plans varies by location and is based on projected benefit obligation and market dynamics. Estimated Future Benefit Payments The following table shows estimated future benefit payments from the Company’s pension plans (in millions): Year Estimated Benefit Payments 2017 $ 100 2018 $ 96 2019 $ 98 2020 $ 97 2021 $ 94 2022-2026 $ 460 Contributions Owens Corning expects to contribute $50 million in cash to the United States pension plan during 2017 and another $9 million to non-United States plans. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements. Defined Contribution Plans The Company sponsors two defined contribution plans which are available to substantially all United States employees. The Company matches a percentage of employee contributions up to a maximum level and contributes up to 2% of an employee’s wages regardless of employee contributions. The Company recognized expense of $38 million , $33 million and $34 million during the years ended December 31, 2016 , 2015 and 2014 , respectively, related to these plans. POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement. Salaried employees hired on or before December 31, 2005 become eligible to participate in the United States health care plans upon retirement if they have accumulated 10 years of service after age 45 , 48 or 50 , depending on the category of employee. For employees hired after December 31, 2005, the Company does not provide subsidized retiree health care. Some of the plans are contributory, with some retiree contributions adjusted annually. The Company has reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements. The Company implemented an Employee Group Waiver Plan ("EGWP") effective January 1, 2013 to manage its prescription drug benefits for certain retiree groups. The Company also negotiated with certain unionized employees to increase the eligibility age for retiree medical benefits and to eliminate the post- 65 retiree reimbursement account benefit for employees retiring on or after January 1, 2014. The following table provides a reconciliation of the change in the projected benefit obligation and the net amount recognized in the Consolidated Balance Sheets for the years ended December 31, 2016 and 2015 (in millions): December 31, 2016 December 31, 2015 U.S. Non-U.S. Total U.S. Non-U.S. Total Change in Projected Benefit Obligation Benefit obligation at beginning of period $ 230 $ 13 $ 243 $ 238 $ 16 $ 254 Service cost 2 — 2 2 — 2 Interest cost 9 — 9 8 1 9 Actuarial gain (15 ) — (15 ) (3 ) — (3 ) Currency gain — — — — (2 ) (2 ) Plan amendments — — — — — — Benefits paid (14 ) (1 ) (15 ) (15 ) (1 ) (16 ) Other — 1 1 — (1 ) (1 ) Benefit obligation at end of period $ 212 $ 13 $ 225 $ 230 $ 13 $ 243 Funded status $ (212 ) $ (13 ) $ (225 ) $ (230 ) $ (13 ) $ (243 ) Amounts Recognized in the Consolidated Balance Sheets Accrued benefit obligation – current $ (17 ) $ (1 ) $ (18 ) $ (17 ) $ (1 ) $ (18 ) Accrued benefit obligation – non-current (195 ) (12 ) (207 ) (213 ) (12 ) (225 ) Net amount recognized $ (212 ) $ (13 ) $ (225 ) $ (230 ) $ (13 ) $ (243 ) Amounts Recorded in Accumulated OCI Net actuarial gain $ (19 ) $ (4 ) $ (23 ) $ (4 ) $ (4 ) $ (8 ) Net prior service credit (12 ) — (12 ) (17 ) — (17 ) Net amount recognized $ (31 ) $ (4 ) $ (35 ) $ (21 ) $ (4 ) $ (25 ) Weighted-Average Assumptions Used to Determine Benefit Obligations The following table presents the discount rates used to determine the benefit obligations: December 31, 2016 2015 United States plans 3.80 % 4.00 % Non-United States plans 3.55 % 3.80 % Components of Net Periodic Postretirement Benefit Cost The following table presents the components of net periodic postretirement benefit cost (in millions): Twelve Months Ended December 31, 2016 2015 2014 Service cost $ 2 $ 2 $ 2 Interest cost 9 9 10 Amortization of prior service cost (4 ) (4 ) (4 ) Amortization of actuarial gain (1 ) (1 ) (2 ) Other 1 1 — Net periodic postretirement benefit cost $ 7 $ 7 $ 6 Weighted-Average Assumptions Used to Determine Net Periodic Postretirement Benefit Cost The following table presents the discount rates used to determine net periodic postretirement benefit cost: Twelve Months Ended December 31, 2016 2015 2014 United States plans 4.00 % 3.70 % 4.35 % Non-United States plans 3.80 % 3.70 % 4.45 % The following table presents health care cost trend rates used to determine net periodic postretirement benefit cost, as well as information regarding the ultimate rate and the year in which the ultimate rate is reached: Twelve Months Ended December 31, 2016 2015 2014 United States plans Initial rate at end of year 6.78 % 7.00 % 7.00 % Ultimate rate 5.00 % 5.00 % 5.00 % Year in which ultimate rate is reached 2025 2025 2024 Non-United States plans Initial rate at end of year 5.07 % 5.25 % 5.43 % Ultimate rate 4.70 % 4.70 % 4.70 % Year in which ultimate rate is reached 2019 2019 2019 The health care cost trend rate assumption can have a significant effect on the amounts reported.

These benefits include continuation of benefits such as health care and life insurance coverage. The accrued postemployment benefits liability at December 31, 2016 and 2015 was $14 million and $15 million , respectively. The net periodic postemployment benefit expense was $2 million for the year ended December 31, 2016 , and $1 million in each of 2015 and 2014 .

CONTINGENT LIABILITIES AND OTHE

CONTINGENT LIABILITIES AND OTHER MATTERS	12 Months Ended

Loss Contingency [Abstract]
CONTINGENT LIABILITIES AND OTHER MATTERS	CONTINGENT LIABILITIES AND OTHER MATTERS The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the “Environmental Matters”) are not material to the Company’s financial statements. Management believes that the ultimate disposition of the Proceedings and the Environmental Matters will not have a material adverse effect on the Company’s financial condition. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period. Litigation and Regulatory Proceedings The Company is involved in litigation and regulatory Proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable. Environmental Matters The Company has established policies and procedures to ensure that its operations are conducted in compliance with all relevant laws and regulations that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, discharges to water, management of hazardous materials, handling and disposal of solid wastes, and remediation of contaminated sites. All Company manufacturing facilities operate using an ISO 14001 or equivalent environmental management system. The Company’s 2020 Sustainability Goals require significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter and toxic air emissions. Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act ("RCRA"), and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of December 31, 2016 , the Company was involved with a total of 19 sites worldwide, including 7 Superfund sites and 12 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company. Remediation activities generally involve a potential range of activities and costs related to soil and groundwater contamination. This can include pre-cleanup activities such as fact finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above. At December 31, 2016 , the Company had an accrual totaling $4 million , for these costs. Changes in required remediation procedures or timing of those procedures, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.

STOCK COMPENSATION

STOCK COMPENSATION	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK COMPENSATION	STOCK COMPENSATION During the fourth quarter of 2016, the Company adopted FASB ASU No. 2016-09. Please refer to Note 20 for discussion of the income tax-related impact of this adoption. No other provisions of this ASU had a material impact on the Consolidated Financial Statements. 2016 Stock Plan On April 21, 2016, the Company's stockholders approved the Owens Corning 2016 Stock Plan (the "2016 Stock Plan") which replaced the 2013 Stock Plan. The 2016 Stock Plan authorizes grants of stock options, stock appreciation rights, restricted stock awards, restricted stock units, bonus stock awards and performance stock awards. At December 31, 2016 , the number of shares remaining available under the 2016 Stock Plan for all stock awards was 3.9 million . Stock Options The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four year vesting period. In general, the exercise price of each option awarded was equal to the closing market price of the Company’s common stock on the date of grant and an option’s maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers prior to 2014. Starting with the options granted in 2014, the volatility was based on the Company’s historic volatility. During 2016 and 2015, no stock options were granted. During 2014, 374,500 stock options were granted with a weighted-average grant date fair value of $19.05 . Assumptions used in the Company’s Black-Scholes valuation model to estimate the grant date fair value were expected volatility of 50.9% , expected dividends of 0% , expected term of 6.25 years and a risk-free interest rate of 1.9% . During the years ended December 31, 2016 , 2015 and 2014 , the Company recognized expense of $2 million , $4 million and $6 million , respectively, related to the Company’s stock options. As of December 31, 2016 , there was $2 million of total unrecognized compensation cost related to stock options. That cost is expected to be recognized over a weighted-average period of 1.09 years. The total aggregate intrinsic value of options outstanding as of December 31, 2016 , 2015 and 2014 was $16 million , $31 million and $16 million , respectively. The total aggregate intrinsic value of options exercisable as of December 31, 2016 , 2015 and 2014 was $13 million , $28 million and $15 million , respectively. Cash received from option exercises was $26 million , $21 million and $8 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Tax benefits realized from tax deductions associated with option exercises totaled $9 million , $4 million and $2 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.

Compensation expense for restricted stock is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the four year vesting period. Restricted stock is subject to alternate vesting plans for death, disability, approved early retirement and involuntary termination, over various periods ending in 2016. During the years ended December 31, 2016 , 2015 and 2014 , the Company recognized expense of $19 million , $17 million and $17 million , respectively, related to the Company’s restricted stock. As of December 31, 2016 , there was $29 million of total unrecognized compensation cost related to restricted stock. That cost is expected to be recognized over a weighted-average period of 2.53 years. The total grant date fair value of shares vested during the years ended December 31, 2016 , 2015 and 2014 , was $15 million , $17 million and $15 million , respectively.

All outstanding performance grants will fully settle in stock. The amount of stock ultimately distributed from the 2016 and 2015 grants is contingent on meeting internal company-based metrics or an external-based stock performance metric. The amount of stock ultimately distributed from 2014 and prior grants is contingent on meeting an external based stock performance metric. In 2016 and 2015, the Company granted both internal company-based and external-based metric PSUs. In 2014, the company granted external-based metric PSU's. Internal Company-based metrics The internal company-based metrics vest after a three -year period and are based on various company-based metrics over a three -year period. The amount of stock distributed will vary from 0% to 300% of PSUs awarded depending on performance versus the company-based metrics. The initial fair value for all internal company-based metric PSUs assumes that the performance goals will be achieved and is based on the grant date stock price. This assumption is monitored quarterly and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected term represents the period from the grant date to the end of the three-year performance period. Pro-rata vesting may be utilized in the case of death, disability or retirement, and awards if earned will be paid at the end of the three-year period. External based metrics The external-based metric vests after a three -year period. Outstanding grants issued in or after 2015 will be based on the Company's total stockholder return relative to the performance of the S&P Building & Construction Industry Index. Outstanding grants issued prior to 2015 are based on the Company's total stockholder return relative to the performance of the companies in the S&P 500 Index. The amount of stock distributed will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance. For all PSUs, respectively, during the years ended December 31, 2016 , 2015 and 2014 , the Company recognized expense of $16 million , $8 million and $6 million . As of December 31, 2016 , there was $16 million of total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.61 years. The total grant date fair value of shares vested during the years ended December 31, 2016 , 2015 and 2014 , was $3 million , $1 million and $1 million , respectively. 2016 Grant For the 2016 grant, the fair value of external based metric PSUs was estimated at the grant date using a Monte Carlo simulation that used various assumptions that include expected volatility of 26.55% , a risk free interest rate of 0.84% and an expected term of 2.91 years. Expected volatility was based on Owens Corning's most recent 2.91 years volatility. The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three -year performance period. For the 2016 grant, the fair value of the internal based metric PSUs was estimated using the grant date stock price and assumed that the performance goals will be achieved. This assumption is monitored each quarter and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted. This adjustment results in either reversing previous surplus compensation expense recognized or recognizing additional expense. 2015 Grant For the 2015 grant, the fair value of external based metric PSUs was estimated at the grant date using a Monte Carlo simulation that used various assumptions that include expected volatility of 29.2% , a risk free interest rate of 1.08% and an expected term of 2.90 years. Expected volatility was based on Owens Corning's most recent 2.90 years volatility. The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three -year performance period. For the 2015 grant, the fair value of the internal based metric PSUs was estimated using the grant date stock price and assumed that the performance goals will be achieved. This assumption is monitored each quarter and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted. This adjustment results in either reversing previous surplus compensation expense recognized or recognizing additional expense. 2014 Grant For the 2014 grant, the fair value of PSUs was estimated at the grant date using a Monte Carlo simulation that used various assumptions that include expected volatility of 36.0% , a risk free interest rate of 0.68% and an expected term of 2.90 years. Expected volatility was based on a benchmark study of our peers. The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three -year performance period.

The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six month period ending on May 31 and November 30 of each year. There were 2 million shares available for purchase under the ESPP as of its approval date. The Company recognized expense related to the ESPP of $3 million , $2 million and $2 million for the years ended December 31, 2016 , 2015 and 2014, respectively. As of December 31, 2016 , the Company had $1 million of total unrecognized compensation costs related to the ESPP. For the years ended December 31, 2016 , 2015 and 2014, our employees purchased 0.2 million shares at an average price of $41.99 , 0.2 million shares at an average price of $32.57 , and 0.2 million shares at an average price of $34.10 , respectively. Under the outstanding ESPP as of January 27, 2017 , employees have contributed $2 million to purchase shares for the current purchase period ending May 31, 2017.

Outstanding shares consist of issued shares less treasury stock. On October 24, 2016, the Board of Directors approved a new share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “2016 Repurchase Authorization"). The 2016 Repurchase Authorization is in addition to the share buy-back program announced April 19, 2012 (the 2012 Repurchase Authorization and collectively with the 2016 Repurchase Authorization, the "Repurchase Authorization"). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company’s discretion. During the year ended December 31, 2016, 4.8 million shares were repurchased under the Repurchase Authorization. As of December 31, 2016, 9.8 million shares remain available for repurchase under the Repurchase Authorization. For the year ended December 31, 2016 , the number of shares used in the calculation of diluted earnings per share did not include 0.1 million performance shares, due to their anti-dilutive effect. For the year ended December 31, 2015 , the number of shares used in the calculation of diluted earnings per share did not include 0.1 million performance shares and 0.6 million options to purchase common stock, due to their anti-dilutive effect. For the year ended December 31, 2014 , the number of shares used in the calculation of diluted earnings per share did not include 1.0 million options to purchase common stock, due to their anti-dilutive effect.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. Items Measured at Fair Value The carrying value of cash and cash equivalents, accounts receivable and short-term debt approximate fair value because of the short-term maturity of the instruments. Derivatives The Company executes financial derivative contracts for the purpose of mitigating risk exposure that is generated from our normal operations. These derivatives consist of natural gas swaps, interest rate swaps, cross currency swaps, and foreign exchange forward contracts, all of which are over-the-counter and not traded through an exchange. The Company uses widely accepted valuation tools to determine fair value, such as discounting cash flows to calculate a present value for the derivatives. The models use Level 2 inputs, such as forward curves and other commonly quoted observable transactions and prices. The following table summarizes the fair values, and levels within the fair value hierarchy in which the fair value measurements fall, for assets and liabilities measured on a recurring basis as of December 31, 2016 (in millions): Total Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Derivative assets $ 16 $ — $ 16 $ — Liabilities: Derivative liabilities $ 2 $ — $ 2 $ — The following table summarizes the fair values, and levels within the fair value hierarchy in which the fair value measurements fall, for assets and liabilities measured on a recurring basis as of December 31, 2015 (in millions): Total Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Derivative assets $ 14 $ — $ 14 $ — Liabilities: Derivative liabilities $ 6 $ — $ 6 $ — Items Disclosed at Fair Value Long-term debt The following table shows the fair value of the Company’s long-term debt as calculated based on quoted market prices for the same or similar issues (Level 2 input), or on the current rates offered to the Company for debt of the same remaining maturities: December 31, 2016 December 31, 2015 6.50% senior notes, net of discount, due 2016 — % 103 % 9.00% senior notes, net of discount, due 2019 114 % 116 % 4.20% senior notes, net of discount, due 2022 104 % 99 % 4.20% senior notes, net of discount, due 2024 102 % 100 % 3.40% senior notes, net of discount, due 2026 95 % — % 7.00% senior notes, net of discount, due 2036 118 % 105 % The Company determined that the book value of the remaining long-term debt instruments approximates market value.

The cumulative temporary differences giving rise to the deferred tax assets and liabilities are as follows (in millions): December 31, 2016 December 31, 2015 Deferred Tax Assets Deferred Tax Liabilities Deferred Tax Assets Deferred Tax Liabilities Other employee benefits $ 117 $ — $ 120 $ — Pension plans 146 — 156 — Operating loss and tax credit carryforwards 826 — 957 — Depreciation — 330 — 315 Amortization — 384 — 367 State and local taxes 5 — 6 — Other 62 — 62 — Subtotal 1,156 714 1,301 682 Valuation allowances (103 ) — (135 ) — Total deferred taxes $ 1,053 $ 714 $ 1,166 $ 682 During the fourth quarter of 2016, the Company adopted ASU No. 2016-09 “Compensation - Stock Compensation (Topic 718).” Under this standard, all excess tax benefits and tax deficiencies related to stock compensation will be recognized as income tax expense or benefit in the income statement. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period, subject to normal valuation allowance considerations. The standard is applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the year of adoption. As of January 1, 2016, we recorded a $14 million increase in Deferred income tax assets and Accumulated earnings. Please refer to our Consolidated Statements of Stockholders’ Equity for further information about this cumulative adjustment. For the twelve months ended December 31, 2016, the adoption of this standard resulted in a $4 million reduction of Income tax expense, substantially all of which related to the fourth quarter of 2016. Our interim quarterly financial information was not revised due to the immaterial impact on those previous quarters. The following table summarizes the amount and expiration dates of our deferred tax assets related to operating loss and credit carryforwards at December 31, 2016 (in millions): Expiration Dates Amounts U.S. federal loss carryforwards 2027 – 2032 $ 584 U.S. state loss carryforwards (a) 2017 – 2034 72 Foreign loss and tax credit carryforwards Indefinite 72 Foreign loss and tax credit carryforwards (a) 2017 – 2034 59 U.S. alternative minimum tax credit Indefinite 19 Other U.S. federal and state tax credits 2028 – 2034 20 Total operating loss and tax credit carryforwards $ 826 (a) As of December 31, 2016 , $17 million of U.S. state and $13 million of foreign deferred tax assets related to loss carryforwards are set to expire over the next three years . At December 31, 2016 , the Company had federal, state and foreign net operating loss carryforwards of $1.8 billion , $2.2 billion and $0.5 billion , respectively. In order to fully utilize our operating loss and tax credit carryforwards, the Company will need to generate federal, state, and foreign earnings before taxes of approximately $1.9 billion , $2.3 billion , and $0.5 billion , respectively. Certain of these loss carryforwards are subject to limitation as a result of the changes of control that resulted from the Company’s emergence from bankruptcy in 2006 and the acquisition of certain foreign entities in 2007. However, the Company believes that these limitations on its loss carryforwards will not result in a forfeiture of any of the carryforwards. Deferred income taxes are provided for temporary differences between amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured under enacted tax laws and regulations, as well as NOLs, tax credits and other carryforwards. A valuation allowance will be recorded to reduce deferred tax assets if, based on all available evidence, it is considered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. To the extent the reversal of deferred tax liabilities is relied upon in our assessment of the realizability of deferred tax assets, they will reverse in the same period and jurisdiction as the temporary differences giving rise to the deferred tax assets. As of December 31, 2016 , the Company had federal, state, and foreign net deferred tax assets before valuation allowances of $287 million , $44 million , and $111 million , respectively. The valuation allowance of $103 million as of December 31, 2016 is related to tax assets of $13 million and $90 million for certain state and foreign jurisdictions, respectively. Realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that the minimum level of taxable income will not be met within the next 12 months to reduce the valuation allowance of certain foreign jurisdictions. The valuation allowance of $135 million as of December 31, 2015 related to tax assets of $11 million and $124 million for certain state and foreign jurisdictions, respectively. The Company, or one of its subsidiaries, files income tax returns in the United States and other foreign jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years before 2013 or state and foreign examinations for years before 2008. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the gross unrecognized tax benefits balance may change within the next 12 months by a range of zero to $14 million . A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in millions): Twelve Months Ended December 31, 2016 2015 2014 Balance at beginning of period $ 84 $ 106 $ 155 Tax positions related to the current year Gross additions 1 1 2 Tax positions related to prior years Gross additions 19 2 10 Gross reductions (5 ) (18 ) (57 ) Settlements (1 ) (7 ) (1 ) Lapses on statutes of limitations — — (3 ) Balance at end of period $ 98 $ 84 $ 106 If these unrecognized tax benefits were to be recognized as of December 31, 2016 , the Company’s income tax expense would decrease by about $75 million . The Company classifies all interest and penalties as income tax expense. As of December 31, 2016 , 2015 and 2014 , the Company recognized $11 million , $8 million and $8 million respectively, in liabilities for tax related interest and penalties on its Consolidated Balance Sheets and $(1) million , $3 million and $2 million , respectively, of interest and penalty expense (income) on its Consolidated Statements of Earnings.

CONDENSED CONSOLIDATING FINANCIAL STATEMENTS	CONDENSED CONSOLIDATING FINANCIAL STATEMENTS The following Condensed Consolidating Financial Statements present the financial information required with respect to those entities which guarantee certain of the Company’s debt. The Condensed Consolidating Financial Statements are presented on the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the Company’s share of the subsidiaries’ cumulative results of operations, capital contributions, distributions and other equity changes. The principal elimination entries eliminate investment in subsidiaries and intercompany balances and transactions. In May 2016, the Company entered into an Acknowledgment and Agreement and Second Amendment to its Credit Agreement which, among other things, removed certain subsidiaries from the list of named guarantors. This amendment had no impact on the composition of the Company’s consolidated group and had no effect on the Consolidated Financial Statements including total stockholders' equity in Guarantor Subsidiaries. The Condensed Consolidating Balance Sheet was revised to present the financial statements of the Guarantor Subsidiaries and Nonguarantor Subsidiaries for December 31, 2015, based on this change in composition. The related increases (decreases) from this revision are shown in the table below (in millions): Description Parent Guarantor Subsidiaries Non-Guarantor Subsidiaries Eliminations Consolidated Due from affiliates - current $ — $ (287 ) $ — $ 287 $ — Investment in subsidiaries — (452 ) — 452 — Due from affiliates — — (739 ) 739 — TOTAL ASSETS $ — $ (739 ) $ (739 ) $ 1,478 $ — Due to affiliates - current $ — $ — $ (287 ) $ 287 $ — Due to affiliates — (739 ) — 739 — Total equity — — (452 ) 452 — TOTAL LIABILITIES AND EQUITY $ — $ (739 ) $ (739 ) $ 1,478 $ — During the second quarter of 2016, the Company discovered classification errors in the December 31, 2015 Condensed Consolidating Balance Sheet related to intercompany activity recorded in the Due from and Due to affiliates, Investment in subsidiary and Equity line items between and among the Parent, Guarantor Subsidiaries and Non-Guarantor Subsidiaries. These classifications errors had no effect on the Consolidated Financial Statements. The effect of correcting these classification errors was not material to the 2015 Condensed Consolidating Balance Sheet, and the related amounts presented as of December 31, 2015 have been revised. The related increases (decreases) from this revision are shown in the table below (in millions): Description Parent Guarantor Subsidiaries Non-Guarantor Subsidiaries Eliminations Consolidated Due from affiliates - current $ — $ (474 ) $ — $ 474 $ — Investment in subsidiaries (484 ) (569 ) (559 ) 1,612 — TOTAL ASSETS $ (484 ) $ (1,043 ) $ (559 ) $ 2,086 $ — Due to affiliates - current $ (484 ) $ — $ 10 $ 474 $ — Total equity — (1,043 ) (569 ) 1,612 — TOTAL LIABILITIES AND EQUITY $ (484 ) $ (1,043 ) $ (559 ) $ 2,086 $ — Additional domestic subsidiaries were added to the Credit Agreement as Guarantor Subsidiaries as of September 30, 2016. As a result, the Condensed Consolidating Financial Statements presented for previous periods were retrospectively revised based on the updated guarantor structure. The impact of this revision was not material to the periods presented. Guarantor and Nonguarantor Financial Statements The Senior Notes and the Senior Revolving Credit Facility are guaranteed, fully, unconditionally and jointly and severally, by certain of Owens Corning’s current and future wholly-owned material domestic subsidiaries that are borrowers or guarantors under the Credit Agreement, which permits changes to the named guarantors in certain situations (collectively, the “Guarantor Subsidiaries”). The remaining subsidiaries have not guaranteed the Senior Notes and the Senior Revolving Credit Facility (collectively, the “Nonguarantor Subsidiaries”).

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (POLICIES)	12 Months Ended

Accounting Policies [Abstract]
Business Description, General and Basis of Presentation	Description of Business Owens Corning, a Delaware corporation, is a leading global producer of glass fiber reinforcements and other materials for composite systems and of residential and commercial building materials. The Company operates within three segments: Composites, which includes the Company’s Reinforcements and Downstream businesses; Insulation and Roofing. Through these lines of business, Owens Corning manufactures and sells products worldwide. The Company maintains leading market positions in many of its major product categories. General On February 2, 2017, the Board of Directors declared a quarterly dividend of $0.20 per common share payable on April 3, 2017 to shareholders of record as of March 10, 2017. During 2016, the Company discovered an error in which certain Value Added Tax ("VAT") balances were inappropriately reported gross versus net in the Consolidated and Condensed Consolidating (Non-Guarantor Subsidiaries) Balance Sheets. We revised the December 31, 2015 balance sheet in these financial statements to correctly report the related VAT balances as either a net asset or a net liability. As of December 31, 2015, this resulted in a decrease to the previously reported Other current assets of $30 million , Other non-current assets of $24 million and Accounts payable and accrued liabilities of $54 million . These revisions were deemed immaterial to the current and prior periods and had no impact on the Consolidated and Condensed Consolidating Statements of Earnings or the Consolidated and Condensed Consolidating Statements of Cash Flows. During the fourth quarter of 2016, the Company adopted Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") No. 2016-09. This adoption resulted in the recognition of a previously unrecognized deferred tax asset as of January 1, 2016. Please refer to the accounting pronouncements section of Note 1, Note 16 and Note 20 for additional detail on this adoption. Basis of Presentation Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes refer to Owens Corning and its subsidiaries. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements of the Company include the accounts of majority-owned subsidiaries. Intercompany accounts and transactions are eliminated.
Reclassifications	Reclassifications Certain reclassifications have been made to the 2015 and 2014 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2016 .
Use of Estimates and Assumptions	Use of Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition Revenue is recognized when title and risk of loss pass to the customer and collectability is reasonably assured. Provisions for discounts and rebates to customers, returns and other adjustments are provided in the same period that the related sales are recorded and are based on historical experience, current conditions and contractual obligations, as applicable.
Cost of Sales	Cost of Sales Cost of sales includes material, labor, energy and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Provisions for warranties are provided in the same period that the related sales are recorded and are based on historical experience, current conditions and contractual obligations, as applicable. Distribution costs include inbound freight costs; purchasing and receiving costs; inspection costs; warehousing costs; shipping and handling costs, which include costs incurred relating to preparing, packaging, and shipping products to customers; and other costs of the Company’s distribution network. All shipping and handling costs billed to the customer are included as net sales in the Consolidated Statements of Earnings.
Marketing and Administrative Expenses	Marketing and Advertising Expenses Marketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications, which are expensed the first time the advertisement takes place.
Science and Technology Expenses	Science and Technology Expenses The Company incurs certain expenses related to science and technology. These expenses include salaries, building and equipment costs, utilities, administrative expenses, materials and supplies associated with the improvement and development of the Company’s products and manufacturing processes. These costs are expensed as incurred.
Earnings (Loss) per Share	Earnings per Share Basic earnings per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect the dilutive effect of common equivalent shares and increased shares that would result from the conversion of equity securities. The effects of anti-dilution are not presented.
Cash and Cash Equivalents	Cash, Cash Equivalents and Restricted Cash The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased.
Accounts Receivable	Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is an estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.
Inventory Valuation	Inventory Valuation Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at lower of cost or market and expense estimates are made for excess and obsolete inventories. Cost is determined by the first-in, first-out (“FIFO”) method.
Investments in Affiliates	Investments in Affiliates The Company accounts for investments in affiliates of 20% to 50% ownership when the Company does not have a controlling financial interest using the equity method under which the Company’s share of earnings and losses of the affiliate is reflected in earnings and dividends are credited against the investment in affiliate when declared.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill assets are not amortized but are tested for impairment on at least an annual basis. In the current year, as part of the annual assessment, the Company used a quantitative approach to determine whether the fair value of a reporting unit was less than its carrying amount. As part of our testing process for goodwill the Company estimates fair values using a discounted cash flow approach from the perspective of a market participant. Significant estimates in the discounted cash flow approach are cash flow forecasts of our reporting units, the discount rate, the terminal business value and the projected income tax rate. The cash flow forecasts of the reporting units are based upon management’s long-term view of our markets and are the forecasts that are used by senior management and the Board of Directors to evaluate operating performance. The discount rate utilized is management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt rating and stock volatility, as measured by beta. The projected income tax rates utilized are the statutory tax rates for the countries where each reporting unit operates. The terminal business value is determined by applying a business growth factor to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, we would evaluate whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill impairment testing. Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include projected cash flows, discount rate, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Indefinite-lived intangible assets purchased through acquisition are generally tested qualitatively for impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years. Identifiable intangible assets with a determinable useful life are amortized over that determinable life.
Properties and Depreciation	Properties and Depreciation Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation when assets are disposed of or otherwise retired. Precious metals used in our production tooling are included in property, plant and equipment and are depleted as they are consumed during the production process. Depletion typically represents an annual expense of less than 3% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of Earnings. For the years ended December 31, 2016 , 2015 and 2014 depreciation expense was $318 million , $278 million and $283 million , respectively. In 2016 , 2015 and 2014, depreciation expense included $19 million , $3 million and $1 million , respectively, of accelerated depreciation related to restructuring actions further explained in Note 11 to the Consolidated Financial Statements. In 2014, depreciation expense also included $3 million of impairment losses on held for sale assets. The range of useful lives for the major components of the Company’s plant and equipment is as follows: Buildings and leasehold improvements 15 – 40 years Machinery and equipment Furnaces 4 – 15 years Information systems 5 – 10 years Equipment 5 – 20 years Expenditures for normal maintenance and repairs are expensed as incurred.
Asset Impairments	Asset Impairments The Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. This requires significant assumptions including projected cash flows, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Changes in management intentions, market conditions or operating performance could indicate that impairment charges might be necessary that would be material to the Company’s Consolidated Financial Statements in any given period.
Income Taxes	Income Taxes The Company recognizes current tax liabilities and assets for the estimated taxes payable or refundable on the tax returns for the current year. Deferred tax balances reflect the impact of temporary differences between the carrying amount of assets and liabilities and their tax basis. Amounts are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. In addition, realization of certain deferred tax assets is dependent upon our ability to generate future taxable income. The Company records a valuation allowance to reduce its deferred tax assets to the amount that it believes is more likely than not to be realized. In addition, the Company estimates tax reserves to cover potential taxing authority claims for income taxes and interest attributable to audits of open tax years.
Taxes Collected From Customers and Remitted to Government Authorities and Taxes Paid to Vendors	Taxes Collected from Customers and Remitted to Government Authorities and Taxes Paid to Vendors Taxes are assessed by various governmental authorities at different rates on many different types of transactions. The Company charges sales tax or Value Added Tax (“VAT”) on sales to customers where applicable, as well as captures and claims back all available VAT that has been paid on purchases. VAT is recorded in separate payable or receivable accounts and does not affect revenue or cost of sales line items in the income statement. VAT receivable is recorded as a percentage of qualifying purchases at the time the vendor invoice is processed. VAT payable is recorded as a percentage of qualifying sales at the time an Owens Corning sale to a customer subject to VAT occurs. Amounts are paid to the taxing authority according to the method and collection prescribed by local regulations. Where applicable, VAT payable is netted against VAT receivable. The Company also pays sales tax to vendors who include a tax, required by government regulations, to the purchase price charged to the Company.
Pension and Other Postretirement Benefits	Pension and Other Postretirement Benefits Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover and medical costs.
Derivative Financial Instruments	Derivative Financial Instruments The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. To the extent that a derivative is effective as a cash flow hedge, the change in fair value of the derivative is deferred in accumulated other comprehensive income/deficit (“OCI”). Any portion considered to be ineffective is reported in earnings immediately. To the extent that a derivative is effective as a fair value hedge, the change in the fair value of the derivative is offset by the change in the fair value of the item being hedged in the Consolidated Statements of Earnings. See Note 4 to the Consolidated Financial Statements for further discussion.
Foreign Currency	Foreign Currency The functional currency of the Company’s subsidiaries is generally the applicable local currency. Assets and liabilities of foreign subsidiaries are translated into United States dollars at the period-end rate of exchange, and their Statements of Earnings and Statements of Cash Flows are converted on an ongoing basis at the monthly average rate. The resulting translation adjustment is included in accumulated OCI in the Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Equity. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the Consolidated Statements of Earnings as incurred.
Accounting Pronouncements	Accounting Pronouncements The following table summarizes recent accounting standard updates ("ASU") issued by the Financial Accounting Standards Board (the "FASB") that could have an impact on the Company's Consolidated Financial Statements: Standard Description Effective Date for Company Effect on the Consolidated Financial Statements Recently issued standards: ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)," as amended by ASU's 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20. This standard outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. Entities can adopt this standard either through a retrospective or modified-retrospective approach. January 1, 2018 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. We expect to complete our assessment in the second half of 2017 and plan to use the modified-retrospective method of adoption. Many of our customer volume commitments are short-term (as explained on pg. 5 of Item 1A Risk Factors) and contain single performance obligations. As a result, we do not expect many elements of this standard to be applicable to our business model. Under our current accounting policy (as described in Note 1 of the Consolidated Financial Statements), we recognize revenue when title and risk of loss pass to the customer and collectability is reasonably assured, and we estimate variable consideration based on historical experience, current conditions and contractual obligations. We believe our current variable consideration estimates are largely consistent with the new standard, but we are still analyzing potential quarterly timing differences for our consignment sales arrangements and customized products manufactured for customers. We are also still assessing the standard's new disclosure requirements, including the disaggregation of segment revenue. ASU 2016-01 "Financial Instruments - Overall (Subtopic 825-10)" This standard modifies certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The update eliminates certain disclosure requirements for financial instruments measured at amortized cost, requires that disclosure of financial instruments be based on an exit price notion, and requires separate presentation of financial assets and liabilities by measurement category and form of financial asset. January 1, 2018 We do not expect the adoption of this standard to have a material impact on our Consolidated Financial Statements. ASU 2016-02 "Leases (Topic 842)" The standard requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. The recognition and presentation of expenses will depend on classification as a finance or operating lease. Entities will adopt this standard through a retrospective approach. January 1, 2019 We are currently assessing the potential impact of this standard adoption on our financial reporting processes and disclosures. We believe that our adoption of the standard will likely have a material impact to our Consolidated Balance Sheets for the recognition of certain operating leases as right-of-use assets and lease liabilities. Our operating lease obligations are described in Note 8 of the Consolidated Financial Statements. We are in the process of analyzing our lease portfolio and evaluating systems to comply with the standard's retrospective adoption requirements. ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326)" This standard replaces the incurred loss methodology for recognizing credit losses with a current expected credit losses model and applies to all financial assets, including trade receivables. Entities will adopt the standard using a modified-retrospective approach. January 1, 2020 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. Our current accounts receivable policy (as described in Note 1 of the Consolidated Financial Statements) uses historical and current information to estimate the amount of probable credit losses in our existing accounts receivable. We have not yet analyzed our current systems and methods to determine the impact of using forward-looking information to estimate expected credit losses. ASU 2016-16 "Income Taxes (Topic 740)" This standard clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. January 1, 2018 We are currently assessing the impact this standard will have on our Consolidated Financial Statements. Recently adopted standards: ASU 2014-15 "Presentation of Financial Statements - Going Concern (Subtopic 205-40)" This standard provides guidance on management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures in the event of such doubt. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2015-07 "Fair Value Measurement (Topic 820)" This standard removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. This standard permitted us to separately present certain assets in the pension plan assets table of Note 13 to the Consolidated Financial Statements. ASU 2015-16 "Business Combinations (Topic 805)" This standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2016-09 "Compensation - Stock Compensation (Topic 718)" This standard simplifies several aspects of the accounting for share-based payment transactions, but may increase volatility in income tax expense. All excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the income statement. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period, subject to normal valuation allowance considerations. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. Please refer to Note 20 of the Consolidated Financial Statements for a detailed explanation of the cumulative effect of adoption recognized on January 1, 2016 and the impact to our Consolidated Statements of Earnings. ASU 2016-15 "Statement of Cash Flows (Topic 230)" This standard addresses the presentation and classification of eight specific cash flow issues, including debt prepayment and extinguishment costs. Entities will adopt the standard using a retrospective method. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements. ASU 2016-18 "Statement of Cash Flows (Topic 230)" This standard requires that a statement of cash flows explain the change in the total of cash, cash equivalents and amounts generally described as restricted cash. Entities will adopt the standard using a retrospective method. January 1, 2016 The adoption of this standard did not have a material impact on our Consolidated Financial Statements.
