Legal and Environmental Matters [Abstract]
Commiments and Contingencies	COMMITMENTS AND CONTINGENCIES We maintain reserves for various contingent liabilities as follows (dollar amounts in millions): June 30, 2023 December 31, 2022 Environmental reserves $ 27 $ 27 Other reserves 16 — Total contingencies 43 27 Current portion (included in Accounts payable and accrued liabilities) (17) (1) Long-term portion $ 26 $ 26 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. Other Proceedings From time to time, we and our subsidiaries are parties to certain legal proceedings. During the second quarter of 2023, we agreed to pay $16 million to resolve certain patent-related claims and to obtain certain patent rights, which is recorded within Other operating credits and charges. Based on the information currently available, management believes the resolution of such ongoing and future proceedings will not have a material effect on our financial position, results of operations, cash flows, or liquidity.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis for Presentation	NATURE OF OPERATIONS AND BASIS FOR PRESENTATION Nature of Operations Louisiana-Pacific Corporation and our subsidiaries are a leading provider of high-performance building solutions that meet the demands of builders, remodelers, and homeowners worldwide. Serving the new home construction, repair and remodeling, and outdoor structures markets, we have leveraged our expertise to become an industry leader known for innovation, quality, reliability, and sustainability. The principal customers for our building solutions are retailers, wholesalers, and home building and industrial businesses in North America and South America, with limited sales to Asia, Australia, and Europe. The Company operates 22 plants across the U.S., Canada, Chile, and Brazil through foreign subsidiaries, an d operates additional facilities through a joint venture. References to "LP," the "Company," "we," "our," and "us" refer to Louisiana-Pacific Corporation and its consolidated subsidiaries as a whole. During the year ended December 31, 2022, we sold our 50% equity interest in t wo joint ventures that produce I-joists, and we sold the remaining assets related to the Engineered Wood Product (EWP) segment. Accordingly, the results of our previously owned EWP segment have been presented as discontinued operations in our Condensed Consolidated Statements of Income for all periods presented. See "Note 7 –Discontinued Operations" for additional information. In May 2023, we acquired a manufacturing facility in Wawa, Ontario from Wawa OSB, Inc. a subsidiary of Forex Inc., for $80 million, financed by a combination of cash on hand and availability under the Amended Credit Facility (defined below). The manufacturing facility is expected to be converted into an LP® SmartSide® Trim & Siding mill. We are evaluating project schedules and market demand to determine when construction will begin. The facility will remain shut down until such time construction is completed. Basis for Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) for interim financial information. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal and recurring nature. These Condensed Consolidated Financial Statements and related Notes should be read in conjunction with our annual report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on February 21, 2023 (2022 Annual Report on Form 10-K). Results of operations for interim periods are not necessarily indicative of results to be expected for an entire year.

Disaggregation of Revenue [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE The following table presents our reportable segment revenues, disaggregated by revenue source. We disaggregate revenue from contracts with customers into major product lines. We have determined that disaggregating revenue into these categories depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. As noted in the segment reporting information in “Note 17 - Selected Segment Data” below, our reportable segments are Siding, Oriented Strand Board (OSB), and South America (dollar amounts in millions).

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, promote sales of products, and 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 estimation 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 centers.

Earnings per Share

Earnings Per Share [Abstract]
Earnings per Share	EARNINGS PER SHARE Basic earnings per share is based on 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 from continuing operations are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share (dollar and share amounts in millions, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Income (loss) from continuing operations $ (21) $ 348 $ 1 $ 769 Net loss attributed to non-controlling interest 1 — — 1 Income (loss) attributed to LP from continuing operations (20) 348 1 770 Income from discontinued operations, net of income taxes — 37 — 99 Net income (loss) attributed to LP $ (20) $ 384 $ 1 $ 868 Weighted average common shares outstanding - basic 72 81 72 83 Dilutive effect of employee stock plans — — — 1 Shares used for diluted earnings per share 72 81 72 84 Net income (loss) attributed to LP per share - basic: Continuing operations $ (0.28) $ 4.30 $ 0.02 $ 9.25 Discontinued operations — 0.46 — 1.18 Net income (loss) attributed to LP per share - basic $ (0.28) $ 4.76 $ 0.02 $ 10.43 Net income (loss) attributed to LP per share - diluted: Continuing operations $ (0.28) $ 4.28 $ 0.02 $ 9.19 Discontinued operations — 0.45 — 1.18 Net income (loss) attributed to LP per share - diluted $ (0.28) $ 4.73 $ 0.02 $ 10.36

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	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. The net carrying value of the 3.625% Senior Notes due in 2029 (2029 Senior Notes) was $347 million and $346 million as of June 30, 2023 and December 31, 2022, respectively.

Upon closing, the Company entered into the transition services agreement with the purchaser of the assets, pursuant to which the Company agreed to support the various activities of the EWP segment, which concluded during the three months ended March 31, 2023.

Goodwill and Intangible Assets Disclosure [Text Block]	GOODWILL AND OTHER INTANGIBLESGoodwill and indefinite-lived intangible assets are not amortized and are subject to assessment for impairment by applying a fair value-based test on an annual basis, or more frequently if circumstances indicate a potential impairment. The Company’s annual assessment date is October 1. During the three months ended June 30, 2023, we recorded impairment charges of $9 million related to developed technology and trademarks related to Entekra, which is discussed further in “Note 8 - Business Exit Charges.” Changes in goodwill and other intangible assets for the six months ended June 30, 2023, are provided in the following table (dollar amounts in millions): Timber Licenses 1 Goodwill Developed Technology Trademarks Beginning balance December 31, 2022 $ 40 $ 19 $ 15 $ 2 Impairment charges — — (7) (2) Amortization (8) — (1) — Ending balance June 30, 2023 $ 32 $ 19 $ 8 $ — 1 Timber licenses are included in Timber and timberlands on the Condensed Consolidated Balance Sheets.

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 from continuing operations for the six months ended June 30, 2023 and 2022, reflected an estimated annual effective tax rate of 34% and 25%, respectively, excluding discrete items discussed below. The total tax provision for the three and six months ended June 30, 2023 was $21 million and $22 million, compared to $116 million and $240 million for the comparable periods in 2022, respectively. The total effective tax rate for continuing operations for the six months ended June 30, 2023 was 95%, compared to 24% for the comparable period in 2022. The total tax provision as a percentage of income from continuing operations is significantly higher for the six months ended June 30, 2023 when compared to same period in 2022. This is primarily a result of a discrete tax expense of $22 million being recorded in the quarter ended June 30, 2023 relating to the change in indefinite reinvestment assertion on Chile and Brazil earnings described in “Item 2 - Management's Discussion and Analysis of Financial Conditions and Results of Operation”. We recognized net discrete tax expense of $15 million and discrete tax benefits of $9 million in the six months ended June 30, 2023 and 2022, respectively. The net discrete tax expense in the current year relates primarily to the second quarter change in management’s indefinite reinvestment assertion on Chile and Brazil earnings described in “Item 2 - Management's Discussion and Analysis of Financial Conditions and Results of Operation” of this quarterly report on Form 10-Q, while the net discrete tax benefit in the prior year primarily relates to excess tax benefits from stock-based compensation.

Asset Impairment Charges [Abstract]
Impairments of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETSWe review the carrying values of our long-lived assets for potential impairments and believe we have adequate support for the carrying values of our long-lived assets. If demand and pricing for our products fall to levels significantly below cycle average demand and pricing, 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, 2023, 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. During the three months ended June 30, 2023, we recorded impairment charges of $12 million and $3 million related to property, plant, and equipment and operating lease assets related to Entekra which were written down to fair value based on Level 2 inputs under ASC 820 using quoted market prices.

In November 2021, the Company initiated the termination of our frozen U.S. and Canadian defined benefit pension plans (collectively, the Plan), which would result in the full settlement of the Company's Plan obligations. During the year ended December 31, 2022, the Company liquidated substantially all of the Plan assets to fund lump-sum distributions to participants and purchase non-participating group annuity contracts. As a result, a substantial portion of the Plan was settled during the year ended December 31, 2022. During the three months ended March 31, 2023, the Company completed the termination of the Plan resulting in the recognition of non-cash, pre-tax charges of $6 million from Accumulated comprehensive loss to Other non-operating items in our Condensed Consolidated Statements of Income. Liquidation of remaining Plan assets in surplus of the defined benefit pension obligation will be made once the Plan satisfies all regulatory requirements, which is expected to be completed during 2023.

Segment Reporting [Abstract]
Selected Segment Data	SELECTED SEGMENT DATA We operate in three segments: Siding, OSB, and South America. Our business units have been aggregated into these three 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 segment Adjusted EBITDA (defined below). Accordingly, our chief operating decision maker evaluates performance and allocates resources based primarily on Net sales and segment Adjusted EBITDA for our business segments. Segment Adjusted EBITDA is defined as Income (loss) attributed to LP from continuing operations before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment attributed to LP, business exit charges, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, pension settlement charges, and other non-operating items. During the three months ended June 30, 2023, we updated our definition of Adjusted EBITDA to exclude other business exit charges not classified as exit operations. Business exit charges consist of inventory and other asset impairment and exit charges related to the exit of businesses not individually significant. We consider business exit charges to be outside the performance of our ongoing core business operations and believe that presenting Adjusted EBITDA excluding business exit charges provides increased transparency as to the operating costs of our current business performance. We did not revise prior years’ Adjusted EBITDA amounts because there were no significant costs similar in nature to these items.
