Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	NOTE 1 - ORGANIZATION Installed Building Products (“IBP”), a Delaware corporation formed on October 28, 2011, and its wholly-owned subsidiaries (collectively referred to as the “Company,” and “we,” “us” and “our”) primarily install insulation, waterproofing, fire-stopping, fireproofing, garage doors, rain gutters, window blinds, shower doors, closet shelving and mirrors and other products for residential and commercial builders located in the continental United States. The Company operates in over 180 locations and its corporate office is located in Columbus, Ohio. We have one operating segment and a single reportable segment. Substantially all of our sales are derived from the service-based installation of various products in the residential new construction, repair and remodel and commercial construction end markets from our national network of branch locations. Each of our branches has the capacity to serve all of our end markets. See Note 3, Revenue Recognition, for information on our revenues by product and end market. The COVID-19 pandemic has caused significant volatility, uncertainty and economic disruption. Many public health organizations and international, federal, state and local governments implemented measures to combat the spread of COVID-19 during portions of the first nine months of 2020 with some of these restrictions still in place as of the date of filing of this Quarterly Report on Form 10-Q. Some of these measures include restrictions on movement such as quarantines, “stay-at-home” orders and social distancing ordinances and restricting or prohibiting outright some or all forms of commercial and business activity. We do not believe the various orders and restrictions or COVID-19 itself significantly impacted our business in the first nine months of 2020. However, the extent to which COVID-19 will impact our future operations, customers, suppliers, employees and financial results is uncertain. The future impact of COVID-19 on our financial results depends on numerous factors including government actions and the resulting impact on construction activity, the effect on our customers’ demand for our services, and the ability of our customers to pay for our services.

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include all of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. The information furnished in the Condensed Consolidated Financial Statements includes normal recurring adjustments and reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations and statements of financial position for the interim periods presented. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) have been omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to prevent the information presented from being misleading when read in conjunction with our audited consolidated financial statements and the notes thereto included in Part II, Item 8, Financial Statements and Supplementary Data, of our Annual Report on Form 10-K 10-K”), Our interim operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected in future operating quarters. Note 2 to the audited consolidated financial statements in our 2019 Form 10-K Recently Adopted Accounting Pronouncements Standard Effective Date Adoption ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) January 1, 2020 This pronouncement and subsequently-issued amendments change the accounting for credit losses on available-for-sale ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 This ASU addresses concerns over the cost and complexity of the two-step one-step ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement January 1, 2020 This pronouncement amends Accounting Standards Codification (“ASC”) ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848) Effective upon issuance This pronouncement contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. The provisions of ASC 848 must be applied at a Topic, Subtopic or Industry Subtopic for all transactions other than derivatives, which may be applied at a hedging relationship level. The relief granted in ASC 848 is applicable only to legacy contracts if the amendments made to the agreements are solely for reference rate reform activities. We elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. Recently Issued Accounting Pronouncements Not Yet Adopted We are currently evaluating the impact of certain ASU’s on our Condensed Consolidated Financial Statements or Notes to Condensed Consolidated Financial Statements, which are described below: Standard Description Effective Date Effect on the financial statements or ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes This pronouncement simplifies the accounting for income taxes by removing certain exceptions to the general principles of Topic 740 and improves the consistent application of GAAP by clarifying and amending existing guidance. Annual periods beginning after December 15, 2020, including interim periods therein. Early adoption is permitted. We are currently assessing the impact of adoption on our consolidated financial statements.

Revenue Recognition

Revenue Recognition	9 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	NOTE 3 - REVENUE RECOGNITION Our revenues are derived primarily through contracts with customers whereby we install insulation and other complementary building products and are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. An insignificant portion of our sales, primarily retail sales, is accounted for on a point-in-time For contracts that are not complete at the reporting date, we recognize revenue over time utilizing a cost-to-cost cost-to-cost Our long-term contracts can be subject to modification to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new, or changes the existing, enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up Payment terms typically do not exceed 30 days for short-term contracts and typically do not exceed 60 days for long-term contracts with customers. All contracts are billed either contractually or as work is performed. Billing on our long-term contracts occurs primarily on a monthly basis throughout the contract period whereby we submit invoices for customer payment based on actual or estimated costs incurred during the billing period. On certain of our long-term contracts the customer may withhold payment on an invoice equal to a percentage of the invoice amount, which will be subsequently paid after satisfactory completion of each installation project. This amount is referred to as retainage and is common practice in the construction industry, as it allows for customers to ensure the quality of the service performed prior to full payment. Retainage receivables are classified as current or long-term assets based on the expected time to project completion. We disaggregate our revenue from contracts with customers by end market and product, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following tables present our revenues disaggregated by end market and product (in thousands): Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 Residential new construction $ 315,434 75 % $ 297,003 75 % $ 912,095 75 % $ 840,806 76 % Repair and remodel 28,625 7 % 25,029 6 % 75,702 6 % 71,254 6 % Commercial 76,427 18 % 74,417 19 % 223,959 19 % 198,338 18 % Net revenues $ 420,486 100 % $ 396,449 100 % $ 1,211,756 100 % $ 1,110,398 100 % Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 Insulation $ 268,292 64 % $ 253,311 64 % $ 779,045 64 % $ 710,005 64 % Waterproofing 33,272 8 % 32,781 8 % 89,855 7 % 84,024 8 % Shower doors, shelving and mirrors 29,282 7 % 27,011 7 % 85,199 7 % 77,828 7 % Garage doors 24,001 6 % 22,336 6 % 68,655 6 % 65,790 6 % Rain gutters 17,295 4 % 13,366 3 % 41,942 4 % 37,561 3 % Window blinds 12,166 3 % 10,615 3 % 34,651 3 % 30,780 3 % Other building products 36,178 8 % 37,029 9 % 112,409 9 % 104,410 9 % Net revenues $ 420,486 100 % $ 396,449 100 % $ 1,211,756 100 % $ 1,110,398 100 % Contract Assets and Liabilities Our contract assets consist of unbilled amounts typically resulting from sales under contracts when the cost-to-cost Contract assets and liabilities related to our uncompleted contracts and customer deposits were as follows (in thousands): September 30, December 31, 2020 2019 Contract assets $ 22,328 $ 22,138 Contract liabilities (11,237 ) (8,888 ) Uncompleted contracts were as follows (in thousands): September 30, December 31, 2020 2019 Costs incurred on uncompleted contracts $ 136,522 $ 110,818 Estimated earnings 75,338 61,185 Total 211,860 172,003 Less: Billings to date 196,640 155,599 Net under billings $ 15,220 $ 16,404 Net under billings were as follows (in thousands): September 30, December 31, 2020 2019 Costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) $ 22,328 $ 22,138 Billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) (7,108 ) (5,734 ) Net under billings $ 15,220 $ 16,404 The difference between contract assets and contract liabilities as of September 30, 2020 compared to December 31, 2019 is primarily the result of timing differences between our performance of obligations under contracts and customer payments. During the three and nine months ended September 30, 2020, we recognized $0.2 million and $7.7 million of revenue, respectively, that was included in the contract liability balance at December 31, 2019. We did not recognize any impairment losses on our receivables and contract assets during the three and nine months ended September 30, 2020 or 2019. Remaining performance obligations represent the transaction price of contracts for which work has not been performed and excludes unexercised contract options and potential modifications. As of September 30, 2020, the aggregate amount of the transaction price allocated to remaining uncompleted contracts was $71.3 million. We expect to satisfy remaining performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months. Practical Expedients and Exemptions We generally expense sales commissions and other incremental costs of obtaining a contract when incurred because the amortization period is usually one year or less. Sales commissions are recorded within selling expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

The Senior Notes will mature on February 1, 2028 and interest will be payable semi-annually in cash in arrears on February 1 and August 1, commencing on February 1, 2020. The net proceeds from the Senior Notes offering were $295.0 million after debt issuance costs. We used some of the net proceeds to repay a portion of our outstanding obligations (including accrued and unpaid interest) under our term loan credit agreement (as defined below) and to pay fees and expenses related to the entry into a new revolving credit facility described below. The indenture covering the Senior Notes contains restrictive covenants that, among other things, limit the ability of the Company and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue preferred stock; (ii) pay dividends on, redeem or repurchase stock; (iii) prepay subordinated debt; (iv) create liens; (v) make specified types of investments; (vi) apply net proceeds from certain asset sales; (vii) engage in transactions with affiliates; (viii) merge, consolidate or sell substantially all of our assets; and (ix) pay dividends and make other distributions from subsidiaries. Credit Facilities In December 2019, we amended and restated our $400 million, seven April 2025 In September 2019, we entered into a new asset-based lending credit agreement (the “ABL Credit Agreement”). The ABL Credit Agreement provides for an asset-based lending credit facility (the “ABL Revolver”) of up to $200.0 million with a five All of the obligations under the Term Loan and ABL Revolver are guaranteed by all of the Company’s existing restricted subsidiaries and will be guaranteed by the Company’s future restricted subsidiaries. Additionally, all obligations under the Term Loan and ABL Revolver, and the guarantees of those obligations, are secured by substantially all of the assets of the Company and the guarantors, subject to certain exceptions and permitted liens, including a first-priority security interest in such assets that constitute ABL Priority Collateral, as defined in the ABL Credit Agreement, and a second-priority security interest in such assets that constitute Term Loan Priority Collateral, as defined in the Term Loan Agreement. The ABL Revolver bears interest at either the Eurodollar rate or the base rate (which approximated the prime rate), at the Company’s election, plus a margin of (A) 1.25% or 1.50% in the case of Eurodollar rate loans (based on a measure of availability under the ABL Credit Agreement) and (B) 0.25% or 0.50% in the case of base rate loans (based on a measure of availability under the ABL Credit Agreement). The ABL Revolver also provides incremental revolving credit facility commitments of up to $50.0 million. The terms and conditions of any incremental revolving credit facility commitments must be no more favorable than the terms of the ABL Revolver. The ABL Revolver also allows for the issuance of letters of credit of up to $75.0 million in aggregate and borrowing of swingline loans of up to $20.0 million in aggregate. The ABL Credit Agreement contains a financial covenant requiring the satisfaction of a minimum fixed charge coverage ratio of 1.0x in the event that we do not meet a minimum measure of availability under the ABL Revolver. Vehicle and Equipment Notes We are party to a Master Loan and Security Agreement (“Master Loan and Security Agreement”), a Master Equipment Lease Agreement (“Master Equipment Agreement”) and one or more Master Loan Agreements (“Master Loan Agreements” and together with the Master Loan and Security Agreement and Master Equipment Agreement the “Master Loan Equipment Agreements”) with various lenders to provide financing for the purpose of purchasing or leasing vehicles and equipment used in the normal course of business. Each financing arrangement under these agreements constitutes a separate note and obligation. Vehicles and equipment purchased or leased under each financing arrangement serve as collateral for the note applicable to such financing arrangement. Regular payments are due under each note for a period of typically 60 consecutive months after the incurrence of the obligation. The specific terms of each note are based on specific criteria, including the type of vehicle or equipment and the market interest rates at the time. No termination date applies to these agreements. As of September 30, 2020, approximately $67.7 million of the various loan agreements was available for purchases of equipment. Total gross assets relating to our Master Loan and Equipment Agreements were $134.4 million and $130.2 million as of September 30, 2020 and December 31, 2019, respectively. The net book value of assets under these agreements was $66.2 million and $68.2 million as of September 30, 2020 and December 31, 2019, respectively. Depreciation of assets held under these agreements is included within cost of sales on the Condensed Consolidated Statements of Operations and Comprehensive Income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 9 - FAIR VALUE MEASUREMENTS Assets and Liabilities Measured at Fair Value on a Recurring Basis In many cases, a valuation technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. During the periods presented, there were no transfers between fair value hierarchical levels. Assets Measured at Fair Value on a Nonrecurring Basis Certain assets, specifically other intangible and long-lived assets, are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis as of September 30, 2020 and December 31, 2019 are categorized based on the lowest level of significant input to the valuation. The assets are measured at fair value when our impairment assessment indicates a carrying value for each of the assets in excess of the asset’s estimated fair value. Undiscounted cash flows, a Level 3 input, are utilized in determining estimated fair values. During each of the three and nine months ended September 30, 2020 and 2019, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. Estimated Fair Value of Financial Instruments Accounts receivable, accounts payable and accrued liabilities as of September 30, 2020 and December 31, 2019 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of certain long-term debt, including the Term Loan and ABL Revolver as of September 30, 2020 and December 31, 2019, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use Derivative financial instruments are measured at fair value based on observable market information and appropriate valuation methods. Contingent consideration liabilities arise from future earnout payments to the sellers associated with certain acquisitions and are based on predetermined calculations of certain future results. These future payments are estimated by considering various factors, including business risk and projections. The contingent consideration liabilities are measured at fair value by discounting estimated future payments to their net present value using the appropriate weighted average cost of capital (WACC). The fair values of financial assets and liabilities that are recorded at fair value in the Condensed Consolidated Balance Sheets and not described above were as follows (in thousands): As of September 30, 2020 As of December 31, 2019 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets: Cash equivalents $ 170,307 $ 170,307 $ — $ — $ 99,242 $ 99,242 $ — $ — Derivative financial instruments 1,759 — 1,759 — — — — — Total financial assets $ 172,066 $ 170,307 $ 1,759 $ — $ 99,242 $ 99,242 $ — $ — Financial liabilities: Contingent consideration $ 3,363 $ — $ — $ 3,363 $ 3,854 $ — $ — $ 3,854 Derivative financial instruments 129 — 129 — 9,446 — 9,446 — Total financial liabilities $ 3,492 $ — $ 129 $ 3,363 $ 13,300 $ — $ 9,446 $ 3,854 See Note 5, Investments, for more information on cash equivalents included in the table above. Also see Note 10, Derivatives and Hedging Activities, for more information on derivative financial instruments. The change in fair value of the contingent consideration (a Level 3 input) was as follows (in thousands): Contingent consideration liability - January 1, 2020 $ 3,854 Preliminary purchase price 2,000 Fair value adjustments (360 ) Accretion in value 532 Amounts cancelled (30 ) Amounts paid to sellers (2,633 ) Contingent consideration liability - September 30, 2020 $ 3,363 The accretion in value of contingent consideration liabilities is included within administrative expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income. The carrying values and associated fair values of financial assets and liabilities that are not recorded at fair value in the Condensed Consolidated Balance Sheets and not described above include our Senior Notes and investments. To estimate fair values of these items, we utilized third-party quotes which are derived all or in part from model prices, external sources or market prices.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NOTE 10 - DERIVATIVES AND HEDGING ACTIVITIES Cash Flow Hedges of Interest Rate Risk Our purpose for using interest rate derivatives is to add stability to interest expense and to manage our exposure to interest rate movements. During the nine months ended September 30, 2020, we used interest rate swaps to hedge the variable cash flows associated with existing variable-rate debt. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes and we currently do not have any derivatives that are not designated as hedges. As of September 30, 2020, we have not posted any collateral related to these agreements. During the three months ended September 30, 2020, we terminated our two existing interest rate swaps and our forward interest rate swap and simultaneously entered into a new forward interest rate swap beginning July 30, 2021. We settled the terminated swaps by making a cash payment of $17.8 million. This payment is classified within cash flows from operating activities within the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020, pursuant to company policy. The unrealized loss included in accumulated other comprehensive loss associated with the terminated swaps of $17.8 million at the time of termination will be amortized to interest expense over the course of the originally scheduled settlement dates of the terminated swaps. During the three and nine months ended September 30, 2020, we amortized $0.6 million of the unrealized loss to interest expense, net. The new forward interest rate swap has a beginning notional of $200.0 million, a fixed rate of 0.51% and a maturity date of April 15, 2030. Upon commencement, this forward swap will serve to hedge substantially all of the variable cash flows on our Term Loan until its maturity and if extended. The changes in the fair value of derivatives designated, and that qualify, as cash flow hedges are recorded in other comprehensive income, net of tax on the Condensed Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Condensed Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no such changes during the nine months ended September 30, 2020 or 2019. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense, net as interest payments are made on our variable-rate debt when the forward interest rate swap begins and as the unrealized loss on our terminated swaps is amortized. Over the next twelve months, we estimate that an additional $3.4 million will be reclassified as an increase to interest expense, net. LIBOR is used as a reference rate for our interest rate swap agreements we use to hedge our interest rate exposure. During the nine months ended September 30, 2020, we adopted ASU 2020-04,

Workers’ compensation known claims and IBNR reserves included on the Condensed Consolidated Balance Sheets were as follows (in thousands): September 30, December 31, 2020 2019 Included in other current liabilities $ 6,341 $ 6,777 Included in other long-term liabilities 12,575 10,874 $ 18,916 $ 17,651 We also had an insurance receivable for claims that exceeded the stop loss limit for fully insured policies included on the Condensed Consolidated Balance Sheets. This receivable offsets an equal liability included within the reserve amounts noted above and was as follows (in thousands): September 30, December 31, 2020 2019 Included in other non-current $ 1,857 $ 2,098 Retirement Plans We participate in multiple 401(k) plans, whereby we provide a matching contribution of wages deferred by employees and can also make discretionary contributions to each plan. Certain plans allow for discretionary employer contributions only. These plans cover substantially all our eligible employees. We recognized 401(k) plan expenses of $0.4 million and $0.5 million during the three months ended September 30, 2020 and 2019, respectively, and $1.6 million and $1.5 million during the nine months ended September 30, 2020 and 2019, respectively. These expenses are included in administrative expenses on the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income. Share-Based Compensation Common Stock Awards We periodically grant shares of our common stock to non-employee non-employee 3 In addition, we granted approximately 0.2 million and 0.1 million shares of our common stock to employees during the nine months ended September 30, 2020 and 2019, respectively. We recorded $1.0 million and $3.0 million of compensation expense associated with non-performance-based 3 During the nine months ended September 30, 2020 and 2019, our employees surrendered approximately 25 thousand and 45 thousand shares of our common stock, respectively, to satisfy tax withholding obligations arising in connection with the vesting of common stock awards issued under our 2014 Omnibus Incentive Plan. We recognized a tax shortfall of $0.3 million for the nine months ended September 30, 2020 and we recognized windfall tax benefits of $0.3 million for the nine months ended September 30, 2019 within the income tax provision in the Condensed Consolidated Statements of Operations and Comprehensive Income. As of September 30, 2020, we had $7.1 million of unrecognized compensation expense related to these nonvested common stock awards issued to non-employee Employees – Performance-Based Stock Awards During the nine months ended September 30, 2020, we issued under our 2014 Omnibus Incentive Plan approximately 0.1 million shares of our common stock to certain officers, which vest in two equal installments on each of April 20, 2021 and April 20, 2022. In addition, during the nine months ended September 30, 2020, we established, and our Board of Directors approved, performance-based targets in connection with common stock awards to be issued to certain officers in 2021 contingent upon achievement of these targets. Share-based compensation expense associated with these performance-based awards and prior performance-based grants was $0.9 million and $2.8 million for the three and nine months ended September 30, 2020, respectively, and $0.8 million and $2.3 million for the three and nine months ended September 3 As of September 30, 2020, we had $5.0 million of unrecognized compensation expense related to nonvested performance-based common stock awards. This expense is subject to future adjustments for forfeitures and is expected to be recognized over the remaining weighted-average period of 1.8 years using the graded-vesting method. See the table below for changes in shares and related weighted average grant date fair value per share. In addition, there are long-term performance-based restricted stock awards to be issued to certain employees annually through 2022 contingent upon achievement of certain performance targets. These awards are accounted for as liability-based awards since they represent a predominantly-fixed monetary amount that will be settled with a variable number of common shares and as such are included in other long-term liabilities on the Consolidated Balance Sheets. During the three and nine months ended September 30, 2020, we recorded $0.5 million and $1.2 million in compensation expense, respectively, associated with these performance-based awards, and we recorded $0.1 million in compensation expense during the nine months ended September 30, 2019. Employees – Performance-Based Restricted Stock Units During 2019, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards which were issued to certain employees in 2020 based upon achievement of a performance target. In addition, during the nine months ended September 30, 2020, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards to be issued to certain employees in 2021 based upon achievement of a performance target. These units will be accounted for as equity-based awards that will be settled with a fixed number of common shares. We recorded $0.1 million and $0.4 million in compensation expense associated with these performance-based units during the three and nine months ended September 30, 2020, respectively, and $0.2 million and $0.5 million for the three and nine months ended September 3 As of September 30, 2020, we had $0.3 million of unrecognized compensation expense related to nonvested performance-based common stock units. This expense is subject to future adjustments for forfeitures and is expected to be recognized on a straight-line basis over the remaining weighted-average period of 0.5 years. See the table below for changes in shares and related weighted average grant date fair value per share. Share-Based Compensation Summary Amounts and changes for each category of equity-based award were as follows: Common Stock Awards Performance-Based Stock Awards Performance-Based Restricted Stock Awards Weighted Awards Weighted Units Weighted Nonvested awards/units at December 31, 2019 152,882 $ 52.93 160,289 $ 50.49 13,186 $ 51.62 Granted 159,876 40.02 57,450 77.28 13,655 36.51 Vested (90,870 ) 49.69 (54,502 ) 51.43 (13,077 ) 51.50 Forfeited/Cancelled (4,023 ) 46.76 — — (491 ) 42.94 Nonvested awards/units at September 30, 2020 217,865 $ 44.93 163,237 $ 59.57 13,273 $ 36.51 We recorded the following stock compensation expense by income statement category (in thousands): Three months ended Nine months ended 2020 2019 2020 2019 Cost of sales $ 60 $ 97 $ 221 $ 280 Selling 45 48 154 149 Administrative 2,530 1,954 7,675 6,012 $ 2,635 $ 2,099 $ 8,050 $ 6,441 Administrative stock compensation expense includes all stock compensation earned by our administrative personnel, while cost of sales and selling stock compensation represents all stock compensation earned by our installation and sales employees, respectively. The difference between the sum of the expenses described above and the amount in the table is comprised of expenses related to immaterial nonrecurring awards. As of September 30, 2020, approximately 2.0 million of the 3.0 million shares of common stock authorized for issuance were available for issuance under the 2014 Omnibus Incentive Plan.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 13 - INCOME TAXES Our provision for income taxes as a percentage of pretax earnings is based on a current estimate of the annual effective income tax rate adjusted to reflect the impact of discrete items. During the three and nine months ended September 30, 2020, our effective tax rate was 25.8% and 26.2%, respectively. The rates were unfavorably impacted by separate tax filing entities in a loss position for which a full valuation allowance is required, resulting in no tax benefit for recognized losses. The rate for the nine months ended September 30, 2020 was also impacted by recognition of a shortfall tax from equity vesting.

Other Commitments and Contingencies From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows. During the year ended December 31, 2018, we entered into an agreement with one of our suppliers to purchase a portion of the insulation materials we utilize across our business. This agreement is effective January 1, 2019 through December 31, 2021 with a purchase obligation of $22.6 million for 2020 and $15.0 million for 2021. For the nine months ended September 30, 2020, we have satisfied $9.1 million of our purchase obligation under this agreement.
