Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	NOTE 1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION About PGT Innovations, Inc. PGT Innovations, Inc. (“PGTI”, “we,” or the “Company”), formerly named PGT, Inc., is a leading manufacturer of impact-resistant aluminum and vinyl-framed windows and doors and offers a broad range of fully customizable window and door products, as well as fully custom overhead garage doors. The majority of our sales are to customers in the state of Florida; however, we also sell products in many other states, the Caribbean, Canada, and in South and Central America. Our acquisition of Eco Enterprises ("Eco Acquisition") in February 2021 expands our range of product offerings in our major market of southeast Florida. We also have sales of products that are designed to unify indoor and outdoor living spaces, through our Western Windows Systems’ (“WWS”) division, and most of its sales are in the western United States. Our acquisitions of Anlin Windows and Doors ("Anlin") in October 2021 and Martin Door Holdings, Inc. ("Martin") in October 2022 expanded our presence in the west. The acquisition of Martin, which produces residential and commercial garage doors, expands the Company into building products adjacent to its portfolio of window and door brands. Products are sold primarily through an authorized dealer and distributor network. We began selling window and door products in the direct-to-consumer channel, a “factory-direct” sales model, through our acquisition of NewSouth Windows Solutions ("NewSouth") in February 2020. We were incorporated in the state of Delaware on December 16, 2003, as JLL Window Holdings, Inc. On February 15, 2006, our Company was renamed PGT, Inc. On December 14, 2016, we announced that we changed our name to PGT Innovations, Inc. and, effective on December 28, 2016, the listing of our common stock was transferred to the New York Stock Exchange (“NYSE”) from the NASDAQ Global Market and began trading on the NYSE under the ticker symbol of “PGTI”. We are headquartered in North Venice, Florida, where we have manufacturing operations, as well as two glass tempering and laminating plants and one insulated glass plant. We also have Florida-based manufacturing operations in Ft. Myers, Tampa, and the greater Miami area. Outside of Florida, we have manufacturing operations in Arizona, California and, more recently, Utah, with the acquisition of Martin. All references to PGTI or our Company apply to the consolidated financial statements of PGT Innovations, Inc. unless otherwise noted. Basis of Presentation These condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. Our condensed consolidated financial statements are unaudited; however, in the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the remainder of the current year or for any future periods. The Company’s fiscal three and nine months ended September 30, 2023 and October 1, 2022 consisted of 13 and 39 weeks, respectively. The condensed consolidated balance sheet as of December 31, 2022, is derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. The condensed consolidated balance sheet as of December 31, 2022, and the unaudited condensed consolidated financial statements as of and for the periods ended September 30, 2023, and October 1, 2022, should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 31, 2022, included in the Company’s most recent Annual Report on Form 10-K. The accounting policies used in the preparation of these unaudited condensed consolidated financial statements are consistent with the accounting policies described in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K. The preparation of financial statements in conformity with GAAP 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 materially differ from those estimates. We have two reportable segments: the Southeast segment and the Western segment. The Southeast reporting segment, which is also an operating segment, is composed of sales from our facilities in Florida. The Western reporting segment, also an operating segment, is composed of sales from our facilities in Arizona, Utah and California. See Note 15 for segment disclosures.

Revenue from Contract with Customer [Abstract]
Revenue Recognition and Contracts with Customers	NOTE 2. REVENUE RECOGNITION AND CONTRACTS WITH CUSTOMERS Disaggregation of Revenue from Contracts with Customers As discussed in Note 1, we have two reportable segments: our Southeast segment and our Western segment. The following table provides information about our net sales by reporting segment, product category and market for the three and nine months ended September 30, 2023 and October 1, 2022: Three Months Ended Nine Months Ended September 30, October 1, September 30, October 1, Disaggregation of revenue (in millions) : 2023 2022 2023 2022 Reporting segment: Southeast $ 302.9 $ 288.2 $ 873.0 $ 867.5 Western 97.0 97.6 288.7 283.5 Total net sales $ 399.9 $ 385.8 $ 1,161.7 $ 1,151.0 Product category: Impact-resistant $ 251.8 $ 227.7 $ 716.6 $ 688.5 Nonimpact-resistant 148.1 158.1 445.1 462.5 Total net sales $ 399.9 $ 385.8 $ 1,161.7 $ 1,151.0 Market: New construction $ 149.9 $ 160.9 $ 453.8 $ 484.3 Repair and remodel 250.0 224.9 707.9 666.7 Total net sales $ 399.9 $ 385.8 $ 1,161.7 $ 1,151.0 The Company’s Western segment includes both custom and volume products. This segment’s volume products are not made-to-order and are of standardized sizes and design specifications. Therefore, the Company’s assessment is that the Western segment’s volume products have alternative uses, and that control of these products passes to the customer at a point in time, which is typically when the product has been delivered to the customer. For the three months ended September 30, 2023 and October 1, 2022, the Western segment’s net sales of its volume products were $ 20.9 million and $ 26.6 million, respectively. For the nine months ended September 30, 2023 and October 1, 2022, the Western segment’s net sales of its volume products were $ 61.7 million and $ 82.6 million, respectively. Contract Balances Contract assets represent sales recognized in excess of billings related to finished goods not yet shipped and certain unused glass components not yet placed into the production process for which revenue is recognized over time. Contract liabilities relate to customer deposits at the end of reporting periods. At September 30, 2023 and December 31, 2022, those contract liabilities totaled $ 27.0 million and $ 39.1 million, respectively, of which $ 20.7 million and $ 33.4 million, respectively, are classified within accrued liabilities, and $ 6.3 million and $ 5.7 million, respectively, are classified as a reduction to the contract assets to which they relate. Contract assets, net, totaled $ 53.9 million at September 30, 2023 and $ 47.9 million at December 31, 2022, in the accompanying condensed consolidated balance sheets. Because of the short-term nature of our performance obligations, as discussed below, substantially all of our performance obligations are satisfied within the quarter following the end of a reporting period. As such, substantially all of the contract liabilities at December 31, 2022 were satisfied in the first quarter of 2023, and contract assets at December 31, 2022 were transferred to accounts receivable in the first quarter of 2023. Also, substantially all of the contract liabilities at September 30, 2023 will be satisfied in the fourth quarter of 2023, and contract assets at September 30, 2023 will be transferred to accounts receivable in the fourth quarter of 2023. Contract liabilities at September 30, 2023 represents cash received during the three-month period ended September 30, 2023, excluding amounts recognized as revenue during that period. Contract assets at September 30, 2023 represents revenue recognized during the three-month period ended September 30, 2023, excluding amounts transferred to accounts receivable during that period. Contract liabilities at December 31, 2022 represents cash received during the three-month period ended December 31, 2022, excluding amounts recognized as revenue during that period. Contract assets at December 31, 2022 represents revenue recognized during the three-month period ended December 31, 2022, excluding amounts transferred to accounts receivable during that period. Allowance for Credit Losses We measure all expected credit losses for financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. In the ordinary course of business, we extend credit to qualified dealers and distributors, generally on a non-collateralized basis. The Company maintains an allowance for credit losses which is based on management’s assessments of the amount which may become uncollectible in the future and is determined through consideration of our write-off history, specific identification of uncollectible accounts based in part on the customer’s past due balance (based on contractual terms), and consideration of prevailing economic and industry conditions, and may include anticipated unfavorable impacts of current macro-economic conditions on the businesses of our customers, such as dealers and distributors. As of September 30, 2023 and December 31, 2022, we had gross accounts receivable of $ 163.8 million and $ 173.8 million, respectively, and an allowance for credit losses of $ 14.5 million and $ 13.7 million, respectively.

Guarantees and Product Warranties [Abstract]
Warranty	NOTE 3. WARRANTY Most of our manufactured products are sold with warranties. Warranty periods, which vary by product components, generally range from 1 to 10 years ; however, the warranty period for a limited number of specifically identified components in certain applications is a lifetime. The majority of the products sold have warranties on components which range from 1 to 3 years . The amount charged to expense for warranties is based on management’s assessment of the cost per service call and the number of service calls expected to be incurred to satisfy warranty obligations on the current net sales. During the three months ended September 30, 2023, we recorded warranty expense at a rate of approximately 2.5 % of sales, which was higher than the rate during the three months ended October 1, 2022 of 1.8 % of sales. The increase in the warranty expense rate in the three months ended September 30, 2023, compared with the rate during the three months ended October 1, 2022, is a result of servicing a higher number of overall warranty claims in the third quarter of 2023, resulting in a higher level of service warranty expense, whereas the rate in the third quarter of 2022 was lower on average as there was a decrease in the use of higher-cost contract labor. During the nine months ended September 30, 2023, we recorded warranty expense at a rate of approximately 2.3 % of sales, which was slightly higher than the rate during the nine months ended October 1, 2022 of 2.0 % of sales. The following table summarizes current period charges, adjustments to previous estimates, as well as settlements, which represent actual costs incurred during the period for the three and nine months ended September 30, 2023 and October 1, 2022. The reserve is determined through assessing our claims history. Of the accrued warranty reserve of $ 16.0 million at September 30, 2023, $ 12.5 million is classified within accrued expenses as current liabilities on the condensed consolidated balance sheet at September 30, 2023, with the remainder classified within other liabilities as non-current liabilities. Of the accrued warranty reserve of $ 15.4 million at December 31, 2022, $ 12.4 million is classified within accrued expenses as current liabilities on the condensed consolidated balance sheet at December 31, 2022, with the remainder classified within other liabilities as non-current liabilities.

Inventory Disclosure [Abstract]
Inventories	NOTE 4. INVENTORIES Inventories consist principally of raw materials purchased for the manufacture of our products. We have limited finished goods inventory since the substantial majority of our products are custom, made-to-order and the revenue on these products, as well as the related cost, has been fully recognized upon completion of the manufacturing process. Finished goods inventory and work-in-progress costs include direct materials, direct labor, and overhead. All inventories are stated at the lower of cost (first-in, first-out method) or net realizable value.

Stock Based Compensation	NOTE 5. STOCK BASED-COMPENSATION Stock-Based Compensation Expense We record stock compensation expense over an equity award’s vesting period based on the award’s fair value at the date of grant. We recorded compensation expense for stock-based awards of $ 3.1 million for the three months ended September 30, 2023, of which $ 2.7 million is classified within selling, general and administrative expenses, and $ 2.7 million for the three months ended October 1, 2022, of which $ 2.3 million is classified within selling, general and administrative expenses. We recorded compensation expense for stock-based awards of $ 9.1 million for the nine months ended September 30, 2023, of which $ 7.8 million is classified within selling, general and administrative expenses, and $ 7.6 million for the nine months ended October 1, 2022, of which $ 6.6 million is classified within selling, general and administrative expenses. Portions of stock compensation expense not classified within selling, general and administrative expenses are classified within cost of sales. As of September 30, 2023, there was $ 22.6 million in total unrecognized compensation cost related entirely to restricted share awards, including time-vesting and those with performance conditions. These costs are expected to be recognized in earnings on an accelerated basis over the weighted average remaining vesting period of 2.2 years at September 30, 2023. All-Employee Grant On September 1, 2023, we issued 347,475 shares of restricted stock to all employees of the Company (the "All-Employee Grant") who do not participate in the Company’s long-term incentive plan. These shares are not subject to adjustment based on any performance or other criteria, but rather, cliff-vest on September 1, 2026, the third anniversary of the grant date, assuming the grantee is employed by the Company on that date. Employees were granted an amount of shares based on their years-of-service as of September 1, 2023, which included 50 shares to those employees who reached at least their one-year anniversary, 75 shares to those who reached at least their two-year anniversary, and 100 shares to those who reached at least their five-year anniversary. Any employee who had not yet reached their one-year anniversary as of September 1, 2023, will be eligible to receive a grant of 50 shares in a second grant to be made on September 1, 2024. The grant date fair value of the All-Employee Grant was $ 28.19 per share.

Business Combinations [Abstract]
Acquisition	NOTE 6. ACQUISITION MARTIN DOORS On October 14, 2022 , we completed the acquisition of the Martin Doors brand. The acquisition was done by WWS Acquisition, LLC, a Missouri limited liability company, indirectly wholly-owned by PGT Innovations, Inc., which acquired all of the shares of stock of Martin Door Holdings, Inc., a Utah corporation, headquartered in Salt Lake City, Utah, a custom manufacturer of overhead garage doors and hardware serving the Western U.S. (the "Martin Acquisition"), pursuant to that certain Share Purchase Agreement dated as of October 14, 2022 (the “Martin Purchase Agreement”). The fair value of consideration transferred in the Martin Acquisition was $ 188.5 million, composed entirely of cash, including $ 185.0 million for purchase price and $ 3.5 million in working capital adjustments, of which $ 2.8 million was estimated and paid at closing, and approximately $ 0.7 million was paid in the first quarter of 2023 upon finalization of the net working capital calculation. The cash portion of the Martin Acquisition was financed with borrowings under the revolving credit facility ("New Revolving Credit Facility") established under fifth amendment ("Fifth Amendment") to the 2016 Credit Agreement ("2016 Credit Agreement due 2027") of $ 98.4 million, with the remaining $ 90.1 million, which includes the approximately $ 0.7 million final net working capital adjustment paid in the first quarter of 2023, funded with cash on hand. Generally, cash on hand for the Martin Acquisition was provided by cash generated through operations. Purchase Price Allocation The preliminary estimated fair value of assets acquired, liabilities assumed and subsequent adjustments to that allocation as of our reporting date, are as follows : Initial Adjustments to Preliminary Accounts receivable $ 6,653 $ ( 194 ) $ 6,459 Inventories 9,543 ( 364 ) 9,179 Contract assets, net 5,242 — 5,242 Prepaid expenses and other assets 90 — 90 Property and equipment 11,422 ( 1,196 ) 10,226 Operating lease right-of-use asset 12,259 — 12,259 Intangible assets 91,900 — 91,900 Total assets acquired 137,109 ( 1,754 ) 135,355 Accounts payable ( 2,482 ) — ( 2,482 ) Accrued and other liabilities ( 1,270 ) 283 ( 987 ) Deferred tax liabilities ( 23,604 ) — ( 23,604 ) Operating lease liability ( 12,259 ) — ( 12,259 ) Total liabilities assumed ( 39,615 ) 283 ( 39,332 ) Net assets acquired 97,494 ( 1,471 ) 96,023 Goodwill 90,300 2,215 92,515 Fair value of consideration transferred $ 187,794 $ 744 $ 188,538 Consideration: Cash $ 187,794 $ 744 $ 188,538 Fair value of consideration transferred $ 187,794 $ 744 $ 188,538 The fair value of certain working capital related items, including Martin’s accounts receivable, prepaid expenses and other assets, and accounts payable and accrued and other liabilities, approximated their book values at the date of the Martin Acquisition. The fair value of inventory was estimated by major category, at net realizable value, which we believe approximates the price a market participant could achieve in a current sale. The substantial majority of inventories at the acquisition date was comprised of raw materials. The fair value of property and equipment and remaining useful lives were estimated by management, with the assistance of a third-party valuation firm, using the cost approach. Valuations of the intangible assets were done using income and royalty relief approaches based on projections provided by management, which we consider to be Level 3 inputs, with the assistance of a third-party valuation firm. During the nine months of 2023, we made immaterial adjustments to our purchase allocation relating to accounts receivable, inventories, property and equipment, and accrued and other liabilities. We incurred acquisition costs totaling $ 4.8 million relating to legal expenses, representations and warranties insurance, diligence, accounting and other services in the Martin Acquisition in the year ended December 31, 2022. Because the Martin Acquisition was an acquisition of stock, Martin's assets and liabilities retain their tax bases at the time of the acquisition. Therefore, none of the identifiable intangible assets or goodwill acquired in the Martin Acquisition are deductible for tax purposes. As of September 30, 2023, goodwill is estimated to be $ 92.5 million. Martin's goodwill is included as part of the Western reporting unit. We believe Martin's goodwill relates to the expansion of our footprint in a key, strategic market we have identified as a geographic area of growth for our Company, as well as being a key component of our strategy to expand into adjacent building material products, other than windows and doors. Pro forma results of operations, as well as net sales and income attributable to the Martin Acquisition are not presented as it did not have a material impact on our results of operations. Valuation of Identified Intangible Assets The valuation of the identifiable intangible assets acquired in the Martin Acquisition and our estimate of their respective useful lives are as follows: Initial Preliminary Useful Life Valuation (in years) (in thousands) Trade name $ 24,000 indefinite Customer relationships 52,700 15 Customer-related backlog (amortized in 2022) 400 < 1 Developed technology 14,600 3 - 14 Non-compete-related intangible 200 5 Intangible assets $ 91,900

Net Income Per Common Share	NOTE 7. NET INCOME PER COMMON SHARE Basic earnings per share (“EPS”) attributable to PGT Innovations, Inc. common stockholders for the nine months ended September 30, 2023, and the three and nine months ended October 1, 2022, is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Diluted EPS attributable to PGT Innovations, Inc. common stockholders for the nine months ended September 30, 2023, and the three and nine months ended October 1, 2022, is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding, including the dilutive effect of common stock equivalents computed using the treasury stock method and the average share price during the period. Basic EPS for the three months ended September 30, 2023, is computed by dividing net income attributable to common shareholders by the average number of common shares outstanding during the period. Diluted EPS for the three months ended September 30, 2023, is computed by dividing net income attributable to common shareholders by the average number of common shares outstanding, including the dilutive effect of common stock equivalents computed using the treasury stock method and the average share price during the period. Anti-dilutive securities excluded from the calculation of weighted average shares outstanding for the three and nine months ended September 30, 2023 and October 1, 2022 were insignificant.

Amortization expense relating to amortizable intangible assets for the nine months ended September 30, 2023 and October 1, 2022, was $ 19.8 million and $ 19.7 million, respectively. We perform our annual goodwill and indefinite-lived intangible asset impairment testing as of the first day of our fiscal fourth quarter of each year, and at interim periods if needed based on occurrence of triggering events. During the three and nine months ended September 30, 2023, we did not identify any events which we believe would trigger the need for tests for impairments of our indefinite-lived intangibles assets prior to our annual assessment date. However, in 2023, we have experienced challenging macro-economic conditions in the markets for our products of our Western segment. Although experiencing some improvement in the third quarter of 2023, should these conditions persist, when combined with potential increases in discount rates due to the rising interest rate environment in 2023, no assurances can be given that any future tests for impairment will indicate that it is more likely than not that the fair values of our indefinite-lived intangible assets will exceed their carrying values for the remainder of 2023. As of September 30, 2023 and December 31, 2022, the carrying value of our Southeast reporting unit goodwill is $ 228.3 million and $ 228.3 million, respectively. As of September 30, 2023 and December 31, 2022, the carrying value of our Western reporting unit goodwill is $ 234.3 million and $ 232.1 million, respectively.

The 2021 Senior Notes due 2029 are jointly and severally and fully and unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future restricted subsidiaries, other than any restricted subsidiary of the Company that does not guarantee the existing senior secured credit facilities or any permitted refinancing thereof. The 2021 Senior Notes due 2029 are senior unsecured obligations of the Company and the guarantors, respectively, and rank pari passu in right of payment with all existing and future senior debt and senior to all existing and future subordinated debt of the Company and the guarantors. The 2021 Senior Notes due 2029 were offered under Rule 144A of the Securities Act, and in transactions outside the United States under Regulation S of the Securities Act, and have not been, and will not be, registered under the Securities Act. The 2021 Senior Notes due 2029 mature on October 1, 2029 . Interest on the 2021 Senior Notes due 2029 is payable semi-annually, in arrears, which began on April 1, 2022, with interest accruing at a rate of 4.375 % per annum from September 24, 2021. We incurred financing costs relating to bank fees and professional services costs relating to the offering and issuance of the 2021 Senior Notes due 2029 totaling $ 8.7 million, which included a 1.25 % lender spread on the total principal value of the 2021 Senior Notes due 2029, or $ 7.2 million, and $ 1.5 million of other costs, all of which are being amortized under the effective interest method. As of September 30, 2023, the face value of debt outstanding under the 2021 Senior Notes due 2029 was $ 575.0 million, and accrued interest was $ 12.6 million. Proceeds from the 2021 Senior Notes due 2029 were used, in part, to redeem in full the $ 425.0 million of 2018 Senior Notes due 2026, including the related fees, costs, and the prepayment call premium of $ 21.5 million, representing 5.063 % of the $ 425.0 million face value then outstanding, prepay the outstanding term loan borrowings under the then existing 2016 Credit Agreement of $ 60.0 million and the related fees and costs, and finance our acquisition of Anlin (the "Anlin Acquisition") in the fourth quarter of 2021. The indenture for the 2021 Senior Notes due 2029 gives us the option to redeem some or all of the 2021 Senior Notes due 2029 at the redemption prices and on the terms specified in the indenture governing the 2021 Senior Notes due 2029. The indenture governing the 2021 Senior Notes due 2029 does not require us to make any mandatory redemptions or sinking fund payments. However, upon the occurrence of a change of control, as defined in the indenture, the Company is required to offer to repurchase the notes at 101 % of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase. We also may make optional redemptions at various premiums including a make-whole call at the then current treasury rate plus 50 basis points prior to October 1, 2024, then 102.188 % on or after August 1, 2024, 101.094 % on or after August 2025, then at 100.000 % on or after August 1, 2026. The indenture for the 2021 Senior Notes due 2029 includes certain covenants limiting the ability of the Company and any guarantors to, (i) incur additional indebtedness; (ii) pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments; (iii) enter into agreements that restrict distributions from restricted subsidiaries; (iv) sell or otherwise dispose of assets; (v) enter into transactions with affiliates; (vi) create or incur liens; merge, consolidate or sell all or substantially all of the Company’s assets; (vii) place restrictions on the ability of subsidiaries to pay dividends or make other payments to the Company; and (viii) designate the Company’s subsidiaries as unrestricted subsidiaries. These covenants are subject to a number of important exceptions and qualifications. 2016 Credit Agreement due 2027 On February 16, 2016 , we entered into the 2016 Credit Agreement. From 2016 to 2022, we entered into various amendments to the 2016 Credit Agreement, including the amendment in October 2022, as described below. On October 13, 2022, the Company entered into the Fifth Amendment of the 2016 Credit Agreement due 2027. The Fifth Amendment provides for, among other things, the New Revolving Credit Facility, which is a new five-year revolving credit facility in an aggregate principal amount of $ 250.0 million. The New Revolving Credit Facility refinances and replaces the previously existing $ 80.0 million revolving credit facility under the 2016 Credit Agreement due 2027. The Company’s obligations under the 2016 Credit Agreement due 2027 continue to be secured by substantially all of its and its direct and indirect subsidiaries’ assets, and is senior in position to the 2021 Senior Notes due 2029. Contemporaneously with the Fifth Amendment, the Company drew down $ 160.0 million of funds available under the New Revolving Credit Facility. Proceeds totaling $ 61.6 million from the $ 160.0 million drawdown were used to repay then existing term loan borrowings under the 2016 Credit Agreement totaling $ 60.0 million, plus accrued interest and fees totaling $ 1.6 million. As discussed below, the remaining $ 98.4 million of proceeds were used to fund the cash portion of the Martin Acquisition. The Company has made net repayments of the $ 160.0 million of initial borrowings under the New Revolving Credit Facility totaling $ 95.0 million through September 30, 2023. Interest on borrowings under the New Revolving Credit Facility is payable either quarterly or at the expiration of any Secured Overnight Financing Rate ("SOFR") interest period applicable thereto. Borrowings under the New Revolving Credit Facility accrue interest at a rate equal to, at our option, a base rate (with a floor of 100 basis points) plus a percentage spread (ranging from 0.75 % to 1.75 %) based on our first lien net leverage ratio or SOFR (with a floor of 0 basis points) plus a percentage spread (ranging from 1.75 % to 2.75 %) based on our first lien net leverage ratio. After giving effect to the Fifth Amendment, we pay a quarterly commitment fee on the unused portion of the New Revolving Credit Facility equal to a percentage spread (ranging from 0.25 % to 0.35 %) based on our first lien net leverage ratio. The Fifth Amendment also modifies the application of the financial covenant under the 2016 Credit Agreement such that testing will occur on a quarterly basis, and requires we maintain a first lien net leverage ratio of not more than 4.00 to 1.00 . We were in compliance with this covenant as of September 30, 2023. The 2016 Credit Agreement due 2027 includes certain covenants limiting the ability of the Company and any guarantors to, (i) incur additional indebtedness; (ii) pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments; (iii) sell or otherwise dispose of assets; (iv) enter into transactions with affiliates; (v) create or incur liens; (vi) merge, consolidate or sell all or substantially all of the Company’s assets; (vii) place restrictions on the ability of subsidiaries to pay dividends or make other payments to the Company; (viii) make investments and (ix) designate the Company’s subsidiaries as unrestricted subsidiaries. These covenants are subject to a number of important exceptions and qualifications. As of September 30, 2023, borrowings outstanding under the $ 250.0 million New Revolving Credit Facility totaled $ 65.0 million, and accrued interest was $ 252 thousand. There were $ 8.5 million in letters of credit outstanding. Availability under the New Revolving Credit Facility at September 30, 2023 totaled $ 176.5 million.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 11. INCOME TAXES The income tax provision for interim periods is comprised of tax on ordinary income provided at the most recent estimated annual effective tax rate, adjusted for the tax effect of discrete items. We estimate the annual effective tax rate quarterly based on the forecasted annual pre-tax results of our operations. The tax effects of items that are unrelated to current year ordinary income are recognized entirely as discrete items in the period identified, including share-based compensation, changes in tax laws and adjustments to the actual liability determined upon filing tax returns. We had income tax expense of $ 13.7 million for the three months ended September 30, 2023, compared with income tax expense of $ 10.1 million for the three months ended October 1, 2022. Our effective tax rate for the three months ended September 30, 2023, was 25.9 % , compared with 24.9 % for the three months ended October 1, 2022. We had income tax expense of $ 36.4 million for the nine months ended September 30, 2023, compared with income tax expense of $ 29.9 million for the nine months ended October 1, 2022. Our effective tax rate for the nine months ended September 30, 2023, was 25.7 % , compared with 24.8 % for the nine months ended October 1, 2022. Our income tax expense for the five months ended May 26, 2023, the date we acquired the 25 % share of Eco we previously did not own, and the nine months ended October 1, 2022, includes income tax expenses of $ 0.9 million and $ 1.0 million, respectively, relating to our 75 % share of the pre-tax earnings of Eco. Income tax expense in the three and nine months ended September 30, 2023, and October 1, 2022, includes discrete items of income tax expense relating to excess taxes from the lapses of restrictions on stock awards and adjustments to tax expense relating to research credit true-ups we made during the third quarter of each period. Income tax expense in the nine months ended October 1, 2022 also includes a refund from the state of Florida, received by the Company in the second quarter of 2022, relating to excess taxes received by the state in 2021, which was $ 584 thousand, benefiting tax expense by $ 462 thousand, net of its Federal tax effect. Excluding discrete items of income tax, the effective tax rates for the three months ended September 30, 2023 and October 1, 2022, would have been an income tax expense rate of 26.7 % and 26.2 % , respectively. Excluding discrete items of income tax, the effective tax rates for the nine months ended September 30, 2023 and October 1, 2022, would have been an income tax expense rate of 26.2 % and 25.7 % , respectively. During the first nine months of 2023, we made payments of estimated taxes totaling $ 39.7 million. During the first nine months of 2022, we made payments of estimated taxes, net of refunds, totaling $ 20.9 million.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	NOTE 12. FAIR VALUE Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A three-tier fair value hierarchy is used to prioritize the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. The accounting guidance concerning fair value allows us to elect to measure financial instruments at fair value and report the changes in fair value through earnings. This election can only be made at certain specified dates and is irrevocable once made. We do not have a policy regarding specific assets or liabilities to elect to measure at fair value, but rather we make the election on an instrument-by-instrument basis as they are acquired or incurred. During the three or nine months ended September 30, 2023 or October 1, 2022, we did no t make any transfers between Level 2 and Level 3 financial assets. We conduct reviews on a quarterly basis to verify pricing, assess liquidity, and determine if significant inputs have changed that would impact the fair value hierarchy disclosure. Fair Value of Financial Instruments Our financial instruments include cash and cash equivalents, accounts and notes receivable, and accounts payable and accrued liabilities, whose carrying amounts approximate their fair values due to their short-term nature. Our financial instruments also include borrowings under the 2016 Credit Agreement due 2027, as well as the 2021 Senior Notes due 2029, all classified as long-term debt. The fair value of borrowings under the 2016 Credit Agreement due 2027 approximated its carrying value due to its variable-rate nature, and were approximately $ 65.0 million and $ 76.4 million as of September 30, 2023, and December 31, 2022, respectively. The fair value of the 2021 Senior Notes due 2029 is based on debt with similar terms and characteristics and was approximately $ 531.9 million as of September 30, 2023, compared to a principal outstanding value of $ 575.0 million, and the fair value was approximately $ 480.8 million as of December 31, 2022, compared to a principal outstanding value of $ 575.0 million. Items Measured at Fair Value The following are measured in the condensed consolidated financial statements at fair value on a recurring basis and are categorized in the table below based upon the lowest level of significant input to the valuation (in thousands): Fair Value Measurements Assets (Liabilities) Quoted Significant Prices in Other Significant Active Observable Unobservable Markets Inputs Inputs September 30, 2023 Total (Level 1) (Level 2) (Level 3) Description Aluminum contracts $ 443 $ — $ 443 $ — MTP contracts ( 24 ) — ( 24 ) — $ 419 $ — $ 419 $ — Fair Value Measurements Assets (Liabilities) Quoted Significant Prices in Other Significant Active Observable Unobservable Markets Inputs Inputs December 31, 2022 Total (Level 1) (Level 2) (Level 3) Description Aluminum contracts $ — $ — $ — $ — MTP contracts 300 — 300 — $ 300 $ — $ 300 $ — See Note 13 for a description of the methods and assumptions used in the determination of the fair values of our aluminum forward and Midwest Transaction Premium (“MTP”) contracts, as well as the basis for classifying these assets and liabilities as Level 2.

Derivatives

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 13. DERIVATIVES Aluminum Contracts and Midwest Transaction Premium We enter into aluminum forward contracts to hedge the fluctuations in the purchase price of aluminum extrusion we use in production, and to hedge the fluctuations in the price of the delivery component of our aluminum extrusion purchases, known as the Midwest Transaction Premium, or MTP. Our contracts are designated as cash flow hedges since they are highly effective in offsetting changes in the cash flows attributable to forecasted purchases of aluminum and the related MTP. We record our aluminum hedge contracts at fair value, based on trading values for aluminum forward contracts. Aluminum forward contracts identical to those held by us trade on the London Metal Exchange (“LME”). The LME provides a transparent forum and is the world’s largest center for the trading of futures contracts for non-ferrous metals. The prices are used by the metals industry worldwide as the basis for contracts for the movement of physical material throughout the production cycle. Based on this high degree of volume and liquidity in the LME, we believe the valuation price at any measurement date for contracts with identical terms as to prompt date, trade date and trade price as those we hold at any time represents a contract’s exit price to be used for purposes of determining fair value. We record our MTP hedge contracts at fair value, based on the Platts MW US Transaction price per pound assessment, which has been a benchmark for decades in the North American aluminum industry. Platts surveys the North American market daily to capture trades, bids and offers on a delivered Midwest basis. Data is normalized to reflect the typical price per pound between the largest number of market participants, for delivery within 7 to 30 days from date of publication, net- 30-day payment terms, for typical order quantities, chemistries and freight allowances. The survey is extensive and encompasses both domestic and offshore producers, traders and brokers that are varied in scope. Based on the extensive nature of this pricing mechanism, we believe the Platts MW US Transaction price at any time represents a contract’s exit price to be used for purposes of determining fair value. Guidance under the Financial Instruments Topic 825 of the Codification requires us to record our hedge contracts at fair value and consider our credit risk for contracts in a liability position, and our counter-party’s credit risk for contracts in an asset position, in determining fair value. We assess our counter-party’s risk of non-performance when measuring the fair value of financial instruments in an asset position by evaluating their financial position, including cash on hand, as well as their credit ratings. We assess our risk of non-performance when measuring the fair value of our financial instruments in a liability position by evaluating our credit ratings, our current liquidity including cash on hand and availability under our revolving credit facility as compared to the maturities of the financial liabilities. We do not offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting arrangement. At September 30, 2023, the fair value of our aluminum forward contracts was in an asset position of $ 0.4 million. We had 18 outstanding forward contracts for the purchase of 13.2 million pounds of aluminum through June 2024, at an average price of $ 1.04 per pound, which excludes the Midwest premium, with maturity dates of between one month and nine months . At September 30, 2023, the fair value of our MTP contracts was de minimis. We had 1 outstanding MTP contract to hedge the Platts US MW Transaction price per pound for the delivery of 2.5 million pounds of aluminum through December 2023, at an average price of $ 0.21 per pound, with a maturity date of three months . We assessed the risk of non-performance of the Company and our counterparty to these contracts, as applicable, and determined it was immaterial and, therefore, did not record any adjustment to their fair values as of September 30, 2023. We assess the effectiveness of our aluminum forward and MTP contracts by comparing the change in the fair value of the forward contract to the change in the expected cash to be paid for the hedged item. The effective portion of the gain or loss on our aluminum forward contracts is reported as a component of accumulated other comprehensive income and is reclassified into earnings in the same line item in the income statement as the hedged item in the same period or periods during which the transaction affects earnings. We expect the amount of accumulated other comprehensive income of approximately $ 0.4 million in the accompanying condensed consolidated balance sheet as of September 30, 2023, to be reclassified to earnings within the next twelve months. The fair values of our aluminum hedges and MTP contracts are classified in the accompanying condensed consolidated balance sheets at September 30, 2023 and December 31, 2022, as follows (in thousands): Derivative Assets Derivative Liabilities September 30, 2023 September 30, 2023 Derivatives designated as hedging instruments under Subtopic 815-20: Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments: Aluminum contracts Other current assets $ 473 Accrued liabilities $ ( 30 ) MTP contracts Other current assets — Accrued liabilities ( 24 ) Aluminum contracts Other assets — Other liabilities — MTP contracts Other assets — Other liabilities — Total derivative instruments Total derivative assets $ 473 Total derivative liabilities $ ( 54 ) Derivative Assets Derivative Liabilities December 31, 2022 December 31, 2022 Derivatives designated as hedging instruments under Subtopic 815-20: Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments: Aluminum contracts Other current assets $ — Accrued liabilities $ — MTP contracts Other current assets 300 Accrued liabilities — Aluminum contracts Other assets — Other liabilities — MTP contracts Other assets — Other liabilities — Total derivative instruments Total derivative assets $ 300 Total derivative liabilities $ — The ending accumulated balance for the aluminum forward and MTP contracts included in accumulated other comprehensive income, net of tax, was an accumulated other comprehensive income of $ 0.3 million as of September 30, 2023, and was an accumulated other comprehensive income of $ 0.2 million at December 31, 2022.

Noncontrolling Interest [Abstract]
Reedemable Non-Controlling Interest	NOTE 16. REEDEMABLE NON-CONTROLLING INTEREST On February 1, 2021, we completed an acquisition of a 75 % ownership stake in Eco. The seller of Eco obtained the remaining equity interest in the newly formed company, Eco Enterprises. The seller’s redeemable non-controlling interest ("RNCI") was initially established at fair value. The agreement between PGT Innovations, Inc. and the seller provided the Company with a call right for seller’s equity interest during the third year following the acquisition date. If the Company did not exercise its right to call by the third anniversary, the agreement provided the seller with a put right which could have been exercised during the 15 -day period following the third anniversary. Effective on May 26, 2023, the Company exercised its call-right to purchase the remaining 25 % ownership stake in Eco it previously did not own. The redemption price of the remaining 25 % was calculated by the Company pursuant to the operating agreement based on the performance metric included therein, and was determined to be $ 37.5 million, which was agreed with by the seller. Subsequent to this redemption, the Company's ownership of Eco Enterprises is now 100 % . The following table presents the changes in the Company’s redeemable non-controlling interest for the nine months ended September 30, 2023, and October 1, 2022: Nine Months Ended September 30, October 1, (in thousands) 2023 2022 Balance at beginning of period $ 34,721 $ 36,863 Net income attributable to redeemable non-controlling interest 1,101 1,334 Change in value of redeemable non-controlling interest 1,637 1,514 Redemption of redeemable non-controlling interest ( 37,459 ) — Balance at end of period $ — $ 39,711

Equity [Abstract]
Shareholders' Equity	NOTE 17. SHAREHOLDERS' EQUITY 2023 Share Repurchase Program On February 7, 2023, the Company announced that its Board of Directors approved a new, share repurchase program which authorizes the Company to purchase up to $ 250.0 million of its common stock. This program permits the Company to purchase shares of its common stock from time to time through open-market purchases, in privately negotiated transactions, or by other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, in accordance with applicable securities laws and other restrictions. During the nine months ended September 30, 2023, we repurchased a total of 3,040,280 shares under this program at a total cost of $ 75.1 million, which excludes the 1 % excise tax imposed on corporate stock buy-backs by the Inflation Reduction Act of 2022. The timing and total amount of stock repurchases will depend upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices, and other considerations. The share repurchase program had an initial term of 3 years , through February 3, 2026, and may be suspended or discontinued at any time, and does not obligate the company to acquire any amount of common stock. Shareholder Rights Plan On March 30, 2023, we announced that our Board of Directors had unanimously approved the adoption of a limited-duration shareholder rights plan (the “Rights Plan”) which includes the declaration of a dividend distribution of one right (each, a “Right”) for each outstanding share of the Company’s common stock to stockholders of record as of the close of business on April 10, 2023. Each Right entitles the registered holder to purchase from the Company 0.001 of a share of Series A Participating Preferred Stock, par value $ 0.01 per share, of the Company at an exercise price of $ 90.00 , subject to adjustment. The complete terms of the Rights are set forth in a Rights Agreement, dated as of March 30, 2023, between the Company and American Stock Transfer & Trust Company, LLC, as rights agent (the "Rights Agreement"). The Rights expire on the earliest of (1) March 30, 2024, unless such date is extended, or (2) the redemption or exchange of the Rights as described above. The Board adopted the Rights Plan in response to a likely accumulation of the Company's shares by a strategic investor. The intent of the Rights Plan is to reduce the likelihood that any entity, person or group gains control of the Company through open market accumulation of the Company's shares without paying all other shareholders an appropriate control premium or without providing the Board sufficient time to make informed judgments and take actions that it believes are in the best interests of its other shareholders. Under the Rights Plan, the rights will become exercisable if an entity, person or group acquires beneficial ownership of 10 % or more of the Company's outstanding common stock in a transaction not approved by the Board. In the event that the Rights become exercisable due to the triggering ownership threshold being crossed, each Right will entitle its holder (other than the person, entity or group triggering the Rights Plan, whose Rights will become void and will not be exercisable) to purchase, at the then-current exercise price, additional shares of common stock having a then-current market value of twice the exercise price of the Right.

Our condensed consolidated financial statements are unaudited; however, in the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the remainder of the current year or for any future periods. The Company’s fiscal three and nine months ended September 30, 2023 and October 1, 2022 consisted of 13 and 39 weeks, respectively. The condensed consolidated balance sheet as of December 31, 2022, is derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. The condensed consolidated balance sheet as of December 31, 2022, and the unaudited condensed consolidated financial statements as of and for the periods ended September 30, 2023, and October 1, 2022, should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 31, 2022, included in the Company’s most recent Annual Report on Form 10-K. The accounting policies used in the preparation of these unaudited condensed consolidated financial statements are consistent with the accounting policies described in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K. The preparation of financial statements in conformity with GAAP 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 materially differ from those estimates. We have two reportable segments: the Southeast segment and the Western segment. The Southeast reporting segment, which is also an operating segment, is composed of sales from our facilities in Florida. The Western reporting segment, also an operating segment, is composed of sales from our facilities in Arizona, Utah and California. See Note 15 for segment disclosures.

Warranty expense rate description			The increase in the warranty expense rate in the three months ended September 30, 2023, compared with the rate during the three months ended October 1, 2022, is a result of servicing a higher number of overall warranty claims in the third quarter of 2023, resulting in a higher level of service warranty expense, whereas the rate in the third quarter of 2022 was lower on average as there was a decrease in the use of higher-cost contract labor.
