Legal and Environmental Matters [Abstract]
Commiments and Contingencies	We maintain reserves for various contingent liabilities as follows: June 30, 2021 December 31, 2020 Environmental reserves $ 14 $ 14 Other reserves — — Total contingencies 14 14 Current portion (included in Accrued liabilities) (1) (1) Long-term portion (included in Other long-term liabilities) $ 13 $ 13 Estimates of our loss contingencies are based on various assumptions and judgments. Due to the numerous uncertainties and variables associated with these assumptions and judgments, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to contingencies and, as additional information becomes known, may change our estimates significantly. While no estimate of the range of any such change can be made at this time, the amount that we may ultimately pay in connection with these matters could materially exceed, in either the near term or the longer term, the amounts accrued to date. Our estimates of our loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may, from time to time, be deemed probable as a result of an insurer’s agreement to payment terms. Environmental Matters We maintain a reserve for undiscounted estimated environmental loss contingencies. This reserve is primarily for estimated future costs of remediation of hazardous or toxic substances at numerous sites currently or previously owned by the Company. Our estimates of our environmental loss contingencies are based on various assumptions and judgments, the specific nature of which varies considering the particular facts and circumstances surrounding each environmental loss contingency. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of the required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect assumptions and judgments as to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities. Due to the numerous uncertainties and variables associated with these assumptions and judgments, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to environmental loss contingencies and, as additional information becomes known, may change our estimates significantly. However, no estimate of the range of any such change can be made at this time. Other Proceedings From time to time, we and our subsidiaries are parties to certain legal proceedings. Based on the information currently available, management believes the resolution of such proceedings will not have a material adverse effect on our financial position, results of operations, cash flows, or liquidity.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. The shipping cost incurred by us to deliver products to our customers is recorded in cost of sales. The expected costs associated with our warranties continue to be recognized as an expense when the products are sold. Our businesses routinely incur customer program costs to obtain favorable product placement, to promote sales of products, and to maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for as deductions from net sales at the time the program is initiated. These reductions from revenue are recorded at the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through, and merchandising support. Management adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). We ship some of our products to customers’ distribution centers on a consignment basis. We retain title to our products stored at the distribution centers. As our products are removed from the distribution centers by retailers and shipped to retailers’ stores, title passes from us to the retailers. At that time, we invoice the retailers and recognize revenue for these consignment transactions. We do not offer a right of return for products shipped to the retailers’ stores from the distribution.

Earnings Per Share [Abstract]
Earnings per Share	EARNINGS PER SHARE Basic earnings per share is based upon the weighted-average number of shares of common stock outstanding. Diluted earnings per share is based upon the weighted-average number of shares of common stock outstanding, plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (stock options, stock-settled appreciation rights (SSARs), restricted stock units, and performance stock units) be excluded from the calculation of diluted earnings per share for the periods in which losses are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share (in millions, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Net income attributed to LP Weighted average common shares outstanding - basic 101 112 103 112 Dilutive effect of employee stock plans 1 1 1 1 Shares used for diluted earnings per share 102 113 104 113 Earnings per share: Basic earnings $ 4.93 $ 0.29 $ 7.90 $ 0.59 Diluted earnings $ 4.90 $ 0.29 $ 7.85 $ 0.58

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	NOTE 4. FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We are required to classify these financial assets and liabilities into two groups: (i) recurring—measured on a periodic basis, and (ii) non-recurring—measured on an as-needed basis. Trading securities consist of rabbi trust financial assets, which are recorded in Other assets in our Condensed Consolidated Balance Sheets. The assets of the rabbi trust are invested in mutual funds and are reported at fair value based on active market quotations, which represent Level 1 inputs. The assets of the rabbi trust were $6 million and $5 million at June 30, 2021, and December 31, 2020, respectively. We estimated our 3.625% Senior Notes due in 2029 (2029 Senior Notes) to have a fair value of $352 million as of June 30, 2021, based upon market quotations. Our 2029 Senior Notes and other long-term debt are categorized as Level 1 in the U.S. GAAP fair value hierarchy. Fair values are based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates. There were no outstanding amounts borrowed under our Amended Credit Facility as of June 30, 2021. During the three and six months ended June 30, 2020, we sold our auction rate securities (ARS) and recognized a $3 million gain on available for sale securities, which is included in Investment income in the Condensed Consolidated Statements of Income.

Redeemable Noncontrolling Interest	NOTE 8. REDEEMABLE NONCONTROLLING INTEREST Redeemable noncontrolling interest is interest in subsidiaries that is redeemable outside of our control either for cash or other assets. These interests are classified as mezzanine equity and measured at the greater of estimated redemption value or carrying value at the end of each reporting period. Net loss attributed to noncontrolling interest is recorded in the Condensed Consolidated Statements of Income. Any adjustments to the redemption value of redeemable noncontrolling interest are recognized in either net income or through accumulated paid-in capital, depending on the nature of the underlying security (preferred or common units). The components of redeemable noncontrolling interest are as follows: Beginning balance December 31, 2020 $ 10 Net loss attributed to noncontrolling interest (1) Ending balance June 30, 2021 $ 9

Debt Disclosure [Abstract]
Long-Term Debt	LONG-TERM DEBTThe following table summarizes our outstanding debt: June 30, 2021 December 31, 2020 2029 Senior Notes $ 350 $ — 2024 Senior Notes — 350 Amended Credit Facility — — Financing leases — 1 Unamortized debt costs (4) (2) Total 346 348 Less: current portion — — Long-term portion $ 346 $ 348 Senior Notes In March 2021, we issued $350 million of the 2029 Senior Notes. We may redeem the 2029 Senior Notes, in whole or in part, prior to March 15, 2024, at a redemption price equal to 100% of the principal amount thereof plus a “make-whole” premium set forth in the indenture governing our 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. On or after March 15, 2024, we may, at our option on one or more occasions, redeem all or any portion of these notes at the redemption prices set forth in the indenture governing the 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. The indenture governing the 2029 Senior Notes contains certain covenants that, among other things, limit our ability to grant liens to secure indebtedness, engage in sale and leaseback transactions and merge or consolidate or sell all or substantially all of our assets. If we are subject to a "change of control," as defined in the indenture, we are required to offer to repurchase the 2029 Senior Notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to, but not including, the date of purchase. The indenture governing the 2029 Senior Notes contains customary events of default, including failure to make required payments on the 2029 Senior Notes, failure to comply with certain agreements or covenants contained in the indenture, failure to pay or acceleration of certain other indebtedness and certain events of bankruptcy and insolvency. An event of default in the indenture allows either the indenture trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding 2029 Senior Notes to accelerate, or in certain cases, automatically causes the acceleration of, the amounts due under the 2029 Senior Notes. In September 2016, LP issued $350 million aggregate principal amount Senior Notes due 2024 (2024 Senior Notes). In February 2021, LP delivered to holders of the 2024 Senior Notes a conditional notice of redemption to redeem on March 27, 2021 all of the 2024 Senior Notes outstanding at a redemption price of 102.438% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date. The redemption notice became irrevocable on March 11, 2021, and the 2024 Senior Notes were fully redeemed on March 27, 2021. In connection with this redemption, LP recorded an early debt extinguishment charge of $11 million, recorded within Other non-operating items on the Condensed Consolidated Statements of Income, which included $9 million of redemption premium and $2 million of unamortized debt costs associated with these notes. Deferred debt costs are amortized over the life of the related debt using a straight-line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to Other non-operating items. During the six months ended June 30, 2021, $2 million of deferred debt costs were written off in association with the 2024 Senior Notes extinguishment, and we paid $4 million in debt issuance costs that will be deferred and amortized over the life of the 2029 Senior Notes. Credit Facility In June 2021, we entered into a third amendment (Third Amendment) to our revolving credit facility, dated as of June 27, 2019 (Credit Facility), with American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer, (as amended, the Amended Credit Facility). The Amended Credit Facility provides a revolving credit facility in the principal amount of up to $550 million, with a $60 million sub-limit for letters of credit. The revolving facility, pursuant to the Amended Credit Facility, terminates, and all loans made thereunder become due in June 2027. LP has granted a security interest in substantially all of its personal property to secure the Amended Credit Facility, and certain of LP’s existing and future wholly-owned domestic subsidiaries may guaranty our obligations under the Amended Credit Facility and, subject to certain limited exceptions, provide security through a security interest in substantially all the personal property of these subsidiaries. The Amended Credit Facility provides a release of security interest after obtaining an Investment Grade rating from any one of the Moody's, S&P, or Fitch. There are no outstanding amounts borrowed under the Amended Credit Facility as of June 30, 2021. Revolving borrowings under the Amended Credit Facility accrue interest, at our option, at either (a) a “base rate” plus a margin of 0.500% to 1.500% or (b) LIBOR plus a margin of 1.500% to 2.500%. The Amended Credit Facility also includes an unused commitment fee, due quarterly, ranging from 0.200% to 0.425%. The applicable margins and fees within these ranges are based on our ratio of consolidated EBITDA to cash interest charges. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (ii) the U.S. prime rate, and (iii) one-month LIBOR plus 1.0%. The Amended Credit Facility contains various restrictive covenants and customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder. The Amended Credit Facility also contains financial covenants that require us and our consolidated subsidiaries to have, as of the end of each quarter, (i) a capitalization ratio (i.e., funded debt less unrestricted cash to total capitalization) of no more than 57.5% and (ii) a minimum consolidated net worth of at least $475 million plus 70% of consolidated net income after December 31, 2019, without a deduction for net losses. In March 2020, LP entered into a letter of credit facility agreement (Letter of Credit Facility) with Bank of America, N.A., which provides for the funding of letters of credit up to an aggregate outstanding amount of $20 million, which may be secured by certain cash collateral of LP. The Letter of Credit Facility includes an unused commitment fee, due quarterly, ranging from 0.50% to 1.875% of the daily available amount to be drawn on each letter of credit issued under the Letter of Credit Facility. The Letter of Credit Facility is subject to similar affirmative, negative, and financial covenants as those set forth in the Amended Credit Facility, including capitalization ratio and minimum net worth covenants. As of June 30, 2021, we secured $13 million of outstanding letters of credit with cash collateral, included in Restricted cash in our Condensed Consolidated Balance Sheets. Deferred debt costs are amortized over the life of the related debt using a straight-line basis, which approximates the effective interest method. Included in such amortized amounts are deferred debt costs associated with our Amended Credit Facility, which are recorded within Other assets on our Condensed Consolidated Balance Sheets . During the three months ended June 30, 2021, we paid $2 million in debt issuance costs in connection with the Third Amendment that was deferred and will be amortized over the life of the Amended Credit Facility. As of June 30, 2021, we were in compliance with all financial covenants under the Amended Credit Facility (as well as the Letter of Credit Facility by such compliance).

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For interim periods, we recognize income tax expense by applying the estimated annual effective income tax rate to year-to-date results unless this method does not result in a reliable estimate of year-to-date income tax expense. Each period, the income tax accrual is adjusted to the latest estimate, and the difference from the previously accrued year-to-date balance is adjusted in the current quarter. Changes in profitability estimates in various jurisdictions will impact our quarterly effective income tax rates. The tax provision for income taxes for the six months ended June 30, 2021 and 2020, reflected an estimated annual tax rate of 24% and 26%, respectively, excluding discrete items discussed below. The total effective tax rate for the three and six months ended June 30, 2021, was 23%, compared to 37% and 30% for the comparable periods in 2020, respectively.

Asset Impairment Charges [Abstract]
Impairments of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETS We review the carrying values of our long-lived assets for potential impairments and believe we have adequate support for the carrying value of our long-lived assets. If demand and pricing for our products fall to levels significantly below cycle average demand and pricing, or should we decide to invest capital in alternative projects, or should changes occur related to our wood supply for our mills, it is possible that future impairment charges will be required. As of June 30, 2021, there were no indications of impairment. We also review from time to time potential dispositions of various assets, considering current and anticipated economic and industry conditions, our strategic plan, and other relevant factors. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.

Segment Reporting [Abstract]
Selected Segment Data	SELECTED SEGMENT DATA We operate in four segments: Siding, OSB, EWP, and South America. Our business units have been aggregated into these four segments based upon the similarity of economic characteristics, customers, and distribution methods. Our results of operations are summarized below for each of these segments separately as well as for the “Other” category, which comprises other products that are not individually significant. We evaluate the performance of our business segments based on net sales and Adjusted EBITDA. Accordingly, our chief operating decision maker evaluates performance and allocates resources based primarily on net sales and Adjusted EBITDA for our business segments. Adjusted EBITDA is a non-GAAP financial measure and is defined as income attributed to LP before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment attributed to LP, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, and other non-operating items.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. The shipping cost incurred by us to deliver products to our customers is recorded in cost of sales. The expected costs associated with our warranties continue to be recognized as an expense when the products are sold. Our businesses routinely incur customer program costs to obtain favorable product placement, to promote sales of products, and to maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for as deductions from net sales at the time the program is initiated. These reductions from revenue are recorded at the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through, and merchandising support. Management adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). We ship some of our products to customers’ distribution centers on a consignment basis. We retain title to our products stored at the distribution centers. As our products are removed from the distribution centers by retailers and shipped to retailers’ stores, title passes from us to the retailers. At that time, we invoice the retailers and recognize revenue for these consignment transactions. We do not offer a right of return for products shipped to the retailers’ stores from the distribution.

Earnings Per Share [Abstract]
Schedule of Earnings Per Share, Basic and Diluted [Table Text Block]	Basic earnings per share is based upon the weighted-average number of shares of common stock outstanding. Diluted earnings per share is based upon the weighted-average number of shares of common stock outstanding, plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (stock options, stock-settled appreciation rights (SSARs), restricted stock units, and performance stock units) be excluded from the calculation of diluted earnings per share for the periods in which losses are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share (in millions, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Net income attributed to LP Weighted average common shares outstanding - basic 101 112 103 112 Dilutive effect of employee stock plans 1 1 1 1 Shares used for diluted earnings per share 102 113 104 113 Earnings per share: Basic earnings $ 4.93 $ 0.29 $ 7.90 $ 0.59 Diluted earnings $ 4.90 $ 0.29 $ 7.85 $ 0.58
