Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	NOTE 1. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements include the accounts of PGT Innovations, Inc. and its direct and indirect wholly-owned subsidiaries, including, PGT Industries, Inc., CGI Window and Door Holdings, Inc. (“CGI”), CGI Commercial, Inc. (“CGIC”), WinDoor, Incorporated, Coyote Acquisition Co. and WWS Acquisition LLC (formerly known as GEF WW Parent LLC) (collectively, the “Company”), after elimination of intercompany accounts and transactions. PGT Innovations, Inc. (“PGTI”, “we,” or the “Company”), formerly named PGT, Inc., manufactures and supplies premium windows and doors. Our highly engineered and technically advanced products can withstand some of the toughest weather conditions on earth and unify indoor/outdoor living spaces. We are also the nation’s largest manufacturer of impact-resistant windows and doors. Our family of brands include CGI®, PGT® Custom Windows & Doors, WinDoor®, Western Window Systems®, CGI Commercial® and Eze-Breeze®. Products are sold through an authorized dealer and distributor network. The majority of our sales are to customers in the state of Florida, but we sell products to customers in many states. We also have sales in the Caribbean, Canada, and in South and Central America. With the acquisition of Western Window Systems (“WWS”), we have an increased level of sales in the western United States. See Note 6 for a discussion of this acquisition. We were incorporated in the state of Delaware on December 16, 2003, as JLL Window Holdings, Inc., with primary operations in North Venice, Florida. 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 (NASDAQ), and began trading on the NYSE under its existing ticker symbol of “PGTI”. We have four manufacturing operations in Florida, and one in Arizona. Our manufacturing facilities in Florida include one in North Venice, two in the greater Miami area, and one in Orlando. Our Arizona operations are in Phoenix. Additionally, we have two glass tempering and laminating plants and one insulation glass plant, all located in North Venice. All references to PGTI or our Company apply to the consolidated financial statements of PGT Innovations, Inc. unless otherwise noted. 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. 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 period is not necessarily indicative of the results that may be expected for the remainder of the current year or for any future periods. Each of the Company’s fiscal quarters ended September 28, 2019, and September 29, 2018, consisted of 13 weeks. The condensed consolidated balance sheet as of December 29, 2018, 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 29, 2018, and the unaudited condensed consolidated financial statements as of and for the periods ended September 28, 2019, should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 29, 2018, included in the Company’s most recent Annual Report on Form 10-K. Except for the adoption of the guidance relating to leases discussed below, 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. Beginning in 2019, we concluded that 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 our sales in Florida, the core market of our legacy business, as well as Alabama, Georgia, Louisiana, Mississippi, North Carolina, South Carolina and the Caribbean. The Western reporting segment, also an operating segment, is composed of sales in the remainder of the United States, along with Canada and Mexico. While both of our operating segments have products, distribution methods and customers of a similar nature, we determined to not aggregate them due to the differences in their geographic markets. Therefore, our operating segments are our reportable segments. See Note 17 for segment disclosures. Recently Adopted Accounting Pronouncements Leases In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. ASU 2016-02 was subsequently amended by ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”; ASU 2018-10, “Codification Improvements to Topic 842, Leases”; and ASU 2018-11, “Targeted Improvements”. The new standard requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard was effective for us on December 30, 2018 (the first day of our 2019 fiscal year), with early adoption permitted. We adopted the new standard on this date, using the required modified retrospective transition approach, applying the new standard to all leases existing on the effective date. Consequently, financial information was not updated, and the disclosures required under the new standard will not be provided for dates and periods prior to December 30, 2018. As of the date of adoption, all of our leases were operating leases, and we have no financing leases as of September 28, 2019. The new standard provided a number of optional practical expedients in transition. We elected the “package of practical expedients”, which permitted us not to reassess under the new standard our prior conclusions about lease identification, lease classification and direct costs, and implemented internal controls and additional lease accounting and tracking procedures to enable the preparation of financial information on adoption. We did not elect the use-of-hindsight practical expedient, or the practical expedient pertaining to land easements as it was not applicable to us. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualified, primarily for leases that are month-to-month leases. This means, for those leases, we did not recognize right-of-use assets or lease liabilities. We also elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets. This standard had a material effect on our consolidated balance sheet relating to the recognition of an operating lease right-of-use asset and operating lease liability for our real estate leases and related to new disclosures about our leasing activities. On adoption, we recognized an operating lease right-of-use asset of $30.5 $32.3 6.2% Leases Accounting Policy We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liability, and operating lease liability, less current portion, on our consolidated balance sheets. Should we engage in any finance leases in the future, finance leases would be included in property and equipment, other current liabilities, and other liabilities on our consolidated balance sheets. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease right-of-use asset also includes any lease payments made and initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Recently Issued Accounting Pronouncements Fair Value Measurement Disclosures In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”. The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company does not believe that the adoption of this guidance will have a significant impact on its fair value disclosures. Financial Instruments – Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. ASU 2016-13 also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. Subsequently, in November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses”. ASU 2018-19 clarifies the codification and corrects unintended application of the guidance. ASU’s 2016-13 and 2018-19 are effective for us for our fiscal year beginning after December 15, 2019. We do not believe that the adoption of this guidance will have a significant impact on our consolidated financial statements. 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 doubtful accounts 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. Uncollectible accounts are written off after repeated attempts to collect from the customer have been unsuccessful. As of September 28, 2019, and December 29, 2018, the allowance for doubtful accounts was million and million, respectively.

Revenue From Contract With Customer [Abstract]
Revenue Recognition and Contracts with Customers	NOTE 2. REVENUE RECOGNITION AND CONTRACTS WITH CUSTOMERS Revenue Recognition Accounting Policy The Company primarily manufactures fully customized windows and doors, and manufactures products based on design specifications, measurements, colors, finishes, framing materials, glass-types, and other options selected by the customer at the point in time an order is received from the customer. The Company has an enforceable right to payment at the time an order is received and accepted at the agreed-upon sales prices contained in our agreements with our customers for all manufacturing efforts expended by the Company on behalf of its customers. Due to the customized build-to-order nature of the Company’s products, the Company’s assessment is that the substantial portion of its finished goods and certain unused glass components have no alternative use, and that control of these products and components passes to the customer over time during the manufacturing of the products in an order, or upon our receipt of certain pre-cut glass components from our supplier attributed to specific customer orders. Based on these factors, the Company recognizes a substantial portion of revenue over time during the manufacturing process once customization begins, and for certain unused glass components on hand, at the end of a reporting period. Revenue on work-in-process at the end of a reporting period is recognized in proportion to costs incurred to total estimated cost of the product being manufactured. Except for the Western segment’s volume products, discussed in the section titled Disaggregation of Revenue from Contracts with Customers below, revenue recognized at a point in time is immaterial. Disaggregation of Revenue from Contracts with Customers As discussed in Note 1, beginning in 2019, we determined that we have two reportable segments: our Southeast business unit and our Western business unit. See Note 17 for more information. The following tables provide information about our net sales by product category and by market for the three and nine months ended September 28, 2019, by segment, and for the three and nine months ended September 29, 2018 (dollars in millions): Segments Three Months Ended September 28, 2019 Southeast Western Total Product category: Impact-resistant window and door products $ 129.5 $ 1.6 $ 131.1 Non-impact window and door products 28.8 37.9 66.7 Total net sales $ 158.3 $ 39.5 $ 197.8 Market: New construction $ 59.7 $ 35.9 $ 95.6 Repair and remodel 98.6 3.6 102.2 Total net sales $ 158.3 $ 39.5 $ 197.8 Segments Three Months Ended September 29, 2018 Southeast Western Total Product category: Impact-resistant window and door products $ 157.2 $ 1.1 $ 158.3 Non-impact window and door products 19.8 21.0 40.8 Total net sales $ 177.0 $ 22.1 $ 199.1 Market: New construction $ 62.7 $ 18.7 $ 81.4 Repair and remodel 114.3 3.4 117.7 Total net sales $ 177.0 $ 22.1 $ 199.1 Segments Nine Months Ended September 28, 2019 Southeast Western Total Product category: Impact-resistant window and door products $ 392.0 $ 3.7 $ 395.7 Non-impact window and door products 64.4 110.0 174.4 Total net sales $ 456.4 $ 113.7 $ 570.1 Market: New construction $ 176.4 $ 105.1 $ 281.5 Repair and remodel 280.0 8.6 288.6 Total net sales $ 456.4 $ 113.7 $ 570.1 Segments Nine Months Ended September 29, 2018 Southeast Western Total Product category: Impact-resistant window and door products $ 422.3 $ 3.3 $ 425.6 Non-impact window and door products 57.7 25.3 83.0 Total net sales $ 480.0 $ 28.6 $ 508.6 Market: New construction $ 174.0 $ 18.7 $ 192.7 Repair and remodel 306.0 9.9 315.9 Total net sales $ 480.0 $ 28.6 $ 508.6 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 and nine months ended September 28, 2019, the Western segment’s net sales of its volume products were $13.8 million and $40.6 million, respectively. For the post-acquisition period from the August 13, 2018 acquisition date to September 29, 2018, the Western segment’s net sales of its volume products were $9.8 million. 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 as noted above. Contract liabilities relate to customer deposits at the end of reporting periods. At September 28, 2019, and December 29, 2018, those contract liabilities totaled $7.6 $8.3 $6.1 $7.8 $1.5 $0.5 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 29, 2018 were satisfied in the first quarter of 2019, and contract assets at December 29, 2018 were transferred to accounts receivable in the first quarter of 2019. Contract liabilities at September 28, 2019 represents cash received during the three-month period ended September 28, 2019, excluding amounts recognized as revenue during that period. Contract assets at September 28, 2019 represents revenue recognized during the three-month period ended September 28, 2019, excluding amounts transferred to accounts receivable during that period. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue as the performance obligation is satisfied. Our contracts with our customers generally represent an approved purchase order, which is typically accounted for as a single performance obligation. In situations when our contract includes distinct goods that are substantially the same and have the same pattern of transfer to the customer over time, they are recognized as a series of distinct goods. We allocate the contract’s transaction price to each distinct performance obligation based on the estimated relative standalone selling price of each distinct good. Observable standalone sales are used to determine the standalone selling price. Performance obligations are satisfied over time, generally for our custom products, and as of a point in time for our standard products. Performance obligations are supported by contracts with customers, and we have elected not to disclose our unsatisfied performance obligations as of September 28, 2019 under the short-term contract exemption as we expect such performance obligations will be satisfied within the quarter following the end of a reporting period. Policies Regarding Shipping and Handling Costs and Commissions on Contract Assets The Company has made a policy election to continue to recognize shipping and handling costs as a fulfillment activity. Treating shipping and handling as a fulfillment activity requires estimated shipping and handling costs for undelivered products and certain glass components on which we have recognized revenue and created a contract asset, to be accrued to match this cost with the recognized revenue. This policy is unchanged from the Company’s policy for recognizing shipping and handling costs prior to the adoption of the new revenue guidance. The Company utilizes the practical expedient which permits expensing of costs to obtain a contract when the expected amortization period is one year or less, which typically results in expensing commissions paid to employees. We expense sales commissions paid to employees as sales are recognized, including sales from the creation of contract assets, as the expected amortization period is less than one year.

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 28, 2019, we recorded warranty expense at a rate of approximately 1.8% 1.7% 1.7% 1.7% The following table summarizes current period charges, adjustments to previous estimates, if necessary, as well as settlements, which represent actual costs incurred during the period for the three and nine months ended September 28, 2019, and September 29, 2018. The reserve is determined through specific identification and assessing Company history.

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 Exercises For the three months ended September 28, 2019, there were 210,931 options exercised at a weighted average exercise price of $2.00 per share. For the nine months ended September 28, 2019, there were 532,931 $2.37 Issuance On February 14, 2019, we granted 258,628 restricted stock awards to certain executives and non-executive employees of the Company under the 2019 Long-Term Incentive Plan (LTIP). The restrictions on these stock awards lapse over time based solely on continued service. However, the quantity of restricted shares granted on half of these shares, or 129,314 shares, is fixed, whereas the quantity granted on the remaining half, or 129,314 shares, is subject to Company-specific performance criteria. The restricted stock awards have a fair value on date of grant of $17.76 per share based on the closing New York Stock Exchange market price of the common stock on the day prior to the day the awards were granted. Those restricted shares whose quantity is fixed vest in equal amounts over a three-year period on the first, second and third anniversary dates of the grant. Those restricted shares whose quantity is subject to Company performance criteria vest in equal amounts on the second and third anniversary dates of the grant, if they are earned. The performance criteria, as defined in the share awards, provides for a graded awarding of shares based on the percentage by which the Company meets earnings before interest and taxes, as defined, in our 2019 business plan. The performance percentages, ranging from less than 80% to greater than 120%, provide for the awarding of shares ranging from no shares to 150% of the target number of shares. On March 1, 2019, we granted an additional 33,663 On May 22, 2019, we granted a total of 37,000 $15.35 Stock 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.

Acquisition	NOTE 6. ACQUISITION WESTERN WINDOW SYSTEMS On August 13, 2018 (the “closing date”), we completed the acquisition of Western Window Systems (“WWS”), which became a wholly-owned subsidiary of PGT Innovations, Inc. The fair value of consideration transferred in the acquisition was $354.6 million. The acquisition was financed with proceeds of $315.0 million from the issuance of the 2018 Senior Notes due 2026, and with $39.6 million in cash on hand. See Note 9 for a discussion of the 2018 Senior Notes due 2026. The estimated fair value of assets acquired, and liabilities assumed as of the closing date, are as follows: Initial Allocation Adjustments to Allocation Final Allocation Accounts and notes receivable $ 7,555 $ (217 ) $ 7,338 Inventories 12,580 — 12,580 Contract assets, net 890 — 890 Prepaid expenses and other assets 1,190 — 1,190 Property and equipment 16,416 (447 ) 15,969 Intangible assets 167,000 — 167,000 Goodwill 164,379 5,162 169,541 Accounts payable (5,622 ) — (5,622 ) Accrued and other liabilities (9,175 ) 53 (9,122 ) Deferred income taxes — (5,180 ) (5,180 ) Purchase price $ 355,213 $ (629 ) $ 354,584 Consideration: Cash $ 355,213 $ (629 ) $ 354,584 Total fair value of consideration $ 355,213 $ (629 ) $ 354,584 The fair value of certain working capital related items, including accounts receivable, prepaid expenses, and accounts payable and accrued liabilities, approximated their book values at the date of the WWS Acquisition. The fair value of inventory was estimated by major category, at net realizable value. The substantial majority of inventories at the acquisition date was composed 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. The WWS Acquisition included its then-existing subsidiary, WWS Blocker LLC (Blocker). Blocker was a single-purpose U.S. tax blocker which held an 18.06% $5.2 We incurred acquisition costs totaling $4.4 $0.7 The remaining consideration, after identified intangible assets and the net assets and liabilities recorded at fair value, has been determined to be $169.5 $139.4 The purchase agreement relating to the WWS Acquisition (PA) has a post-closing working capital calculation whereby we were required to prepare, and which we delivered to the sellers, a final statement of purchase price, including our calculation of actual net working capital as of the closing date. The calculation resulted in a net decrease in purchase price of $0.6 Net sales and net income included in the consolidated condensed statements of comprehensive income for the three and nine months ended September 29, 2018, from WWS from the August 13, 2018 acquisition date was $18.7 million and $2.3 million, respectively.

Interest on the 2018 Senior Notes due 2026 is payable semi-annually, in arrears, beginning on February 16, 2019, with interest accruing at a rate of 6.75% per annum from August 10, 2018. We incurred financing costs relating to bank fees and professional services costs relating to the offering and issuance of the 2018 Senior Notes due 2026 totaling $10.4 $315.0 $3.5 The indenture for the 2018 Senior Notes due 2026 gives us the option to redeem some or all of the 2018 Senior Notes due 2026 at the redemption prices and on the terms specified in the indenture governing the 2018 Senior Notes due 2026. The indenture governing the 2018 Senior Notes due 2026 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. The indenture for the 2018 Senior Notes due 2026 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 2022 On February 16, 2016, we entered into the 2016 Credit Agreement due 2022, among us, the lending institutions identified in the 2016 Credit Agreement due 2022, and SunTrust Bank, as Administrative Agent and Collateral Agent. The 2016 Credit Agreement due 2022 establishes new senior secured credit facilities in an aggregate amount of $310.0 million, consisting of a $270.0 million Term B term loan facility maturing in February 2022 that amortizes on a basis of 1% annually during its six-year term, and a $40.0 million revolving credit facility maturing in February 2021 that includes a swing line facility and a letter of credit facility. Our obligations under the 2016 Credit Agreement due 2022 are subject to exceptions, guaranteed by substantially all of our wholly-owned direct and indirect subsidiaries that are restricted subsidiaries and secured by substantially all of our assets as well as our direct and indirect restricted subsidiaries’ assets. On March 16, 2018, we entered into an amendment of our 2016 Credit Agreement due 2022 (the “Second Amendment”). The Second Amendment, among other things, decreases the applicable interest rate margins for the Initial Term Loans (as defined in the 2016 Credit Agreement due 2022) from (i) 3.75% to 2.50%, in the case of the Base Rate Loans (as defined in the 2016 Credit Agreement due 2022), and (ii) 4.75% to 3.50%, in the case of the Eurodollar Loans (as defined in the 2016 Credit Agreement due 2022). On February 17, 2017, we entered into the first amendment to our 2016 Credit Agreement due 2022, which also resulted in decreases in the applicable margins, but which, unlike the Second Amendment, did not include any changes in lender positions. In connection with the Second Amendment, certain existing lenders changed their positions in or exited the 2016 Credit Agreement due 2022, which resulted in the write-offs of portions of the deferred financing costs and original issue discount allocated to these lenders. Additionally, at the time of the issuance of the 2018 Senior Notes due 2026, certain existing lenders reduced their positions in the revolving credit portion of the 2016 Credit Agreement due 2022, which resulted in the write-offs of the deferred financing costs allocated to these lenders. As such, write-offs totaling $3.4 million is classified as debt extinguishment costs in the accompanying condensed consolidated statement of operations for the nine months ended September 29, 2018. Regarding the first amendment as described above, as there were no changes in lender positions, this action did not result in any modifications or extinguishments of debt. Therefore, there was no charge for debt extinguishment costs in 2017. Interest on all loans under the 2016 Credit Agreement due 2022 is payable either quarterly or at the expiration of any LIBOR interest period applicable thereto. Prior to amending the 2016 Credit Agreement due 2022 on March 16, 2018, as described above, borrowings under the term loans and the revolving credit facility accrued interest at a rate equal to, at our option, LIBOR (with a floor of 100 basis points in respect of the term loan), or a base rate (with a floor of 200 basis points in respect of the term loan) plus an applicable margin. The applicable margin was 475 basis points in the case of LIBOR and 375 basis points in the case of the base rate. The weighted average all-in interest rate for borrowings under the term-loan portion of the 2016 Credit Agreement due 2022 was 5.69% 5.84% We also pay quarterly fees on the unused portion of the revolving credit facility equal to 50 basis points per annum as well as a quarterly letter of credit fee at 575 basis points per annum plus a 12.5 basis point facing fee per annum on the face amount of any outstanding letters of credit. As of September 28, 2019, there were $2.1 $37.9 The 2016 Credit Agreement due 2022 contains a springing financial covenant that would apply if we draw in excess of twenty percent (20%) of the revolving facility commitment (excluding $7.5 million of undrawn letters of credit and letters of credit and draws thereunder that are cash collateralized at 105% of the stated amount thereof from such availability test). To the extent in effect, the springing financial covenant would prohibit us from exceeding a maximum first lien net leverage ratio (based on the ratio of total first lien (less unrestricted cash) debt to EBITDA) as of the last day of each applicable fiscal quarter. To the extent the springing financial covenant is in effect, the first lien net leverage ratio cannot exceed 4.00:1.00 as of the last day of the fiscal quarter ending on September 28, 2019. We were not required to test our first lien net leverage ratio for the quarter ending September 28, 2019 because we did not exceed 20% of our revolving capacity. The 2016 Credit Agreement due 2022 also contains a number of affirmative and restrictive covenants, including limitations on the incurrence of additional debt, liens on property, acquisitions and investments, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, dividends and other payments in respect of our capital stock, entry into restrictive agreements, prepayments of certain debt and transactions with affiliates, in each case, subject to exceptions and qualifications. The 2016 Credit Agreement due 2022 also contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the 2016 Credit Agreement due 2022 may be accelerated and may become immediately due and payable. On September 18, 2018, we completed an underwritten, public offering of 7,000,000 shares of our common stock, at a public offering price of $23.00 per share (the “2018 Equity Issuance”). The offering resulted in gross proceeds to the Company of $161.0 million. Net of an underwriting fee of $1.15 per share, net cash proceeds to the Company approximated $153.0 million. Contemporaneously with the 2018 Equity Issuance, we prepaid million in borrowings outstanding under the term loan portion of the 2016 Credit Agreement due 2022. On December 19, 2018, we voluntarily prepaid an additional million in borrowings under the 2016 Credit Agreement due 2022. As of September 28, 2019, the principal amount of debt outstanding under the 2016 Credit Agreement due 2022 was million, and accrued interest was million. See Note 18, Subsequent Events, for a discussion of a third amendment to the 2016 Credit Agreement due 2022, which we entered into effective on October 31, 2019. Deferred Financing Costs The activity relating to third-party fees and costs, lender fees and discount for the nine months ended September 28, 2019, are as follows. All debt-related fees, costs and original issue discount are classified as a reduction of the carrying value of long-term debt: (in thousands) Total At beginning of year $ 12,361 Less: Amortization expense relating to 2016 Credit Agreement (552 ) Less: Amortization expense relating to 2018 Senior Notes (751 ) At end of period $ 11,058 Estimated amortization expense relating to third-party fees and costs, lender fees and discount for the years indicated as of September 28, 2019, is as follows: (in thousands) Total Remainder of 2019 $ 449 2020 1,913 2021 1,893 2022 1,353 2023 1,359 Thereafter 4,091 Total $ 11,058 As a result of prepayments of the 2016 Credit Agreement due 2022 totaling $204.0 (in thousands) Remainder of 2019 $ — 2020 — 2021 — 2022 63,975 2023 — Thereafter 315,000 Total $ 378,975 Other Debt In July 2017, we entered into a two-year financing arrangement for the purchase of an enterprise-wide software license relating to office productivity software. This financing arrangement requires 24 monthly payments of $26 thousand each. We estimated the value of this financing arrangement to be $590 thousand, using an imputed annual interest rate of 6.00%, which approximated our then borrowing rate under the 2016 Credit Agreement due 2022, a Level 3 input. At September 28, 2019, this agreement had been fully repaid. At December 29, 2018, there was $163 thousand, outstanding under this financing arrangement.

Leases [Abstract]
Leases	NOTE 10. LEASES We lease certain of our manufacturing facilities under operating leases. We also lease production equipment, vehicles, computer equipment, storage units and office equipment under operating leases. Our leases have remaining lease terms of 1 year to 9 years, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year. All of our leases are operating leases. We did not recognize right-of-use assets or lease liabilities for certain short-term leases that are month-to-month leases. The lease expense relating to these leases is not significant. The components of lease expense for the three and nine months ended September 28, 2019, are as follows (in thousands): Three Months Ended Nine Months Ended September 28, September 28, 2019 2019 Operating lease cost $ 1,546 $ 4,506 Variable lease cost 714 2,046 Total lease cost $ 2,260 $ 6,552 Other information relating to leases for the three and nine months ended September 28, 2019, are as follows (in thousands, except years and percentages): Three Months Ended Nine Months Ended September 28, September 28, 2019 2019 Supplemental cash flows information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows relating to operating leases $ (1,546 ) $ (4,506 ) Right-of-use assets obtained in exchange for lease obligations: Operating leases $ - $ - Weighted average remaining lease term in years Operating leases 4.13 4.13 Weighted average discount rate Operating leases 6.2 % 6.2 % Future minimum lease payments under non-cancellable leases were as follows at September 28 , 2019, and December 29, 2018 (in thousands): September 28, December 29, 2019 2018 Remainder of 2019 $ 1,589 $ 6,343 2020 6,093 6,354 2021 4,555 4,748 2022 3,673 3,831 2023 3,644 3,801 Thereafter 17,421 17,885 Total future minimum lease payments 36,975 $ 42,962 Less: Imputed interest (7,785 ) Operating lease liability - total $ 29,190 Reported as of September 28, 2019 Current portion of operating lease liability $ 4,551 Operating lease liability, less current portion 24,639 Operating lease liability - total $ 29,190 As of September 28, 2019, we had no additional operating or finance leases that have not yet commenced.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 12. INCOME TAXES Our income tax expense was $3.9 million for the three months ended September 28, 2019, compared with $3.3 million for the three months ended September 29, 2018. Our effective tax rate for the three months ended September 28, 2019, was 20.4%, and was 19.7% for the three months ended September 29, 2018. Our income tax expense was $11.3 $8.7 21.8% 16.8% Income tax expense in the three months ended September 28, 2019, and September 29, 2018, includes excess tax benefits relating to exercises of stock options and lapses of restrictions on stock awards, treated as a discrete item of income tax, totaling $665 thousand and $1.0 million, respectively $1.7 and $4.6 million, respectively 25.3% 25.6% As a result of the Tax Cuts and Jobs Act, enacted effective on December 22, 2017, our Federal corporate income tax rate has been reduced from 35%, to 21%. This reduction in rate has lowered our overall effective tax rate. Additionally, the section 199 domestic manufacturing deduction was repealed. As such, our estimated annual effective tax rate, excluding the discrete items discussed above, approximates our current combined statutory federal and state rate of 25.6%. During the nine months ended September 28, 2019, we made payments of estimated federal and state income taxes totaling $10.8 $17.2 relating to taxpayers in certain designated areas of Florida impacted by Hurricane Irma in September 2017 , which included all counties in Florida in which we operate. As a result, the deadline for remitting our required 2017 third quarter estimated payment for corporate income taxes was extended to January 31, 2 018.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 13. 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 28, 2019, or September 29, 2018, we did not 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, accrued liabilities and other debt, whose carrying amounts approximate their fair values due to their short-term nature. Our financial instruments also include borrowings under our 2016 Credit Agreement due 2022, as well as the 2018 Senior Notes due 2026, both classified as long-term debt. The fair value of borrowings under the 2016 Credit Agreement due 2022 is based on debt with similar terms and characteristics and was approximately $64.1 million as of September 28, 2019, compared to a principal outstanding value of $64.0 million, and fair value of $63.2 million as of December 29, 2018, compared to a principal outstanding value of $64.0 million. The fair value of the 2018 Senior Notes due 2026 is also based on debt with similar terms and characteristics and was approximately $340.2 million as of September 28, 2019, compared to a principal outstanding value of $315.0 million, and the fair value was approximately $311.9 million as of December 29, 2018, compared to a principal outstanding value of $315.0 million. Fair values were determined based on observed trading prices of our debt between domestic financial institutions, which we consider to be a Level 2 input. Items Measured at Fair Value on a Recurring Basis The following are measured in the 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 September 28, Markets Inputs Inputs 2019 (Level 1) (Level 2) (Level 3) Description Aluminum forward contracts, net $ (2,531 ) $ - $ (2,531 ) $ - $ (2,531 ) $ - $ (2,531 ) $ - Fair Value Measurements Assets (Liabilities) Quoted Significant Prices in Other Significant Active Observable Unobservable December 29, Markets Inputs Inputs 2018 (Level 1) (Level 2) (Level 3) Description Aluminum forward contracts $ (4,118 ) $ - $ (4,118 ) $ - $ (4,118 ) $ - $ (4,118 ) $ - The following is a description of the methods and assumptions used to estimate the fair values of the Company’s assets and liabilities measured at fair value on a recurring basis, as well as the basis for classifying these assets and liabilities as Level 2. 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.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 14. DERIVATIVES Aluminum Contracts We enter into aluminum forward contracts to hedge the fluctuations in the purchase price of aluminum extrusion we use in production. 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. 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. At September 28, 2019, the fair value of our aluminum forward contracts was in a net liability 36 34.5 $0.87 one fifteen We assess the effectiveness of our aluminum forward 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 loss 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. The amount of losses, net, recognized in the “accumulated other comprehensive loss” line item in the accompanying condensed consolidated balance sheet as of September 28, 2019, that we expect will be reclassified to earnings within the next twelve months, is approximately $2.4 million. The fair value of our aluminum hedges are classified in the accompanying consolidated balance sheets at September 28, 2019, and December 29, 2018, as follows (in thousands): Derivative Assets Derivative Liabilities September 28, 2019 September 28, 2019 Derivatives designated as hedging instruments under Subtopic 815-20: Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments: Aluminum forward contracts Other current assets $ — Accrued liabilities $ (2,436 ) Aluminum forward contracts Other assets — Other liabilities (95 ) Total derivative instruments Total derivative assets $ — Total derivative liabilities $ (2,531 ) Derivative Assets Derivative Liabilities December 29, 2018 December 29, 2018 Derivatives designated as hedging instruments under Subtopic 815-20: Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments: Aluminum forward contracts Other current assets $ — Accrued liabilities $ (3,907 ) Aluminum forward contracts Other assets — Other liabilities (211 ) Total derivative instruments Total derivative assets $ — Total derivative liabilities $ (4,118 ) The ending accumulated balance for the aluminum forward contracts included in accumulated other comprehensive losses, net of tax, was $1.9 $3.1 The following represents the gains (losses) on derivative financial instruments, and their classifications within the accompanying condensed consolidated financial statements, for the three and nine months ended September 28, 2019, and September 29, 2018 (in thousands): Derivatives in Cash Flow Hedging Relationships Amount of Gain or (Loss) Recognized in OCI(L) on Derivatives Location of Gain or (Loss) Reclassified from Accumulated OCI(L) into Income Amount of Gain or (Loss) Reclassified from Accumulated OCI(L) into Income Three Months Ended Three Months Ended September 28, September 29, September 28, September 29, 2019 2018 2019 2018 Aluminum contracts $ (1,136 ) $ (649 ) Cost of sales $ (1,532 ) $ (58 ) Derivatives in Cash Flow Hedging Relationships Amount of Gain or (Loss) Recognized in OCI(L) on Derivatives Location of Gain or (Loss) Reclassified from Accumulated OCI(L) into Income Amount of Gain or (Loss) Reclassified from Accumulated OCI(L) into Income Nine Months Ended Nine Months Ended September 28, September 29, September 28, September 29, 2019 2018 2019 2018 Aluminum contracts $ (2,083 ) $ (1,122 ) Cost of sales $ (3,670 ) $ (15 )

Shareholders' Equity	NOTE 16. SHAREHOLDERS’ EQUITY On May 22, 2019, our Board of Directors authorized and approved a share repurchase program of up to $30 million. The repurchases may be made in open market or private transactions from time to time. Repurchases of shares may be made under a Rule 10b5-1 plan, which would permit repurchases when we might otherwise be precluded from doing so under applicable laws. We base repurchase decisions, including the timing of repurchases, on factors such as our stock price, general economic and market conditions, the potential impact on our capital structure, the expected return on competing uses of capital such as strategic acquisitions and capital investments, and other corporate considerations, as determined by our management. The repurchase program may be suspended or discontinued at any time. We do not intend to repurchase any shares from directors, officers, or other affiliates. The program does not obligate us to acquire any specific number of shares. The timing, manner, price and amount of repurchases will be determined at our discretion, and the program may be suspended, terminated or modified at any time for any reason. No repurchases were made under the program during the period from the inception of the program on May 22, 2019, through the end of the second quarter of 2019. During the three months ended September 28, 2019, we made repurchases of 393,819 $5.5

Segment Reporting [Abstract]
Segments	NOTE 17. SEGMENTS 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 our sales in Florida, the core market of our legacy business, as well as Alabama, Georgia, Louisiana, Mississippi, North Carolina, South Carolina and the Caribbean. The Western reporting segment, also an operating segment, is composed of sales in the remainder of the United States, along with Canada and Mexico. The operations of the Western reporting segment are composed primarily of the results of WWS and the results of the legacy operations of the Company in the west. While both of our operating segments have products, distribution methods and customers of a similar nature, we determined to not aggregate them due to the differences in their geographic markets. Therefore, our operating segments are also our reportable segments. Centralized financial and operational oversight, including resource allocation and assessment of performance on an income (loss) from operations basis, is performed by our CEO, whom we have determined to be our chief operating decision maker (“CODM”), with oversight by the Board of Directors. Total asset information by segment is not included herein as asset information by segment is not presented to or reviewed by the CODM. The following table represents summary financial data attributable to our operating segments for the three and nine months ended September 28, 2019, and September 29, 2018.

Subsequent Events	NOTE 18. SUBSEQUENT EVENTS Amendment to 2016 Credit Agreement On October 31, 2019, we entered into an amendment of our 2016 Credit Agreement due 2022 (“Third Amendment”). The Third Amendment provides for, among other things, (i) a new three-year Term A loan in the aggregate principal amount of $64.0 $80.0 $40.0 Pursuant to the Third Amendment, interest on all loans under the 2016 Credit Agreement is payable either quarterly or at the expiration of any LIBOR interest period applicable thereto. The Third Amendment decreases the applicable interest rate margins for the Initial Term Loan A from (i) 2.50% to a spread of 1.00% to 1.75% based on our first lien net leverage ratio, in the case of the Base Rate Loans (with a floor of 100 basis points), and (ii) 3.50% to a spread ranging from 2.00% to 2.75% based on our first lien leverage ratio, in the case of the Eurodollar Loans (with a floor of zero basis points). Also, in connection with the Third Amendment, we will pay quarterly fees on the unused portion of the revolving credit facility equal to a percentage spread (ranging from 0.25% to 0.35%) based on our first lien net leverage ratio. The Third Amendment also modifies the springing financial covenant under the 2016 Credit Agreement to provide that such financial covenant will not be tested until the Initial Term A Loan is paid in full. We estimate that fees and costs relating to the Third Amendment will be approximately $0.8 In connection with the Third Amendment, certain existing lenders modified their positions in or exited the 2016 Credit Agreement. We expect that deferred financing costs and original issue discount allocated to these lenders of approximately $1.5 Announcement of Executive Departure On October 27, 2019, Scott Gates notified the Company that he will resign his position as President of the Company’s Western Business Unit and its Western Window Systems business, effective January 31, 2020. Following his resignation, Mr. Gates plans to establish a social entrepreneurship organization that will provide jobs, skills training and career paths for those in prison and former inmates.

Revenue From Contract With Customer [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Leases In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. ASU 2016-02 was subsequently amended by ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”; ASU 2018-10, “Codification Improvements to Topic 842, Leases”; and ASU 2018-11, “Targeted Improvements”. The new standard requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard was effective for us on December 30, 2018 (the first day of our 2019 fiscal year), with early adoption permitted. We adopted the new standard on this date, using the required modified retrospective transition approach, applying the new standard to all leases existing on the effective date. Consequently, financial information was not updated, and the disclosures required under the new standard will not be provided for dates and periods prior to December 30, 2018. As of the date of adoption, all of our leases were operating leases, and we have no financing leases as of September 28, 2019. The new standard provided a number of optional practical expedients in transition. We elected the “package of practical expedients”, which permitted us not to reassess under the new standard our prior conclusions about lease identification, lease classification and direct costs, and implemented internal controls and additional lease accounting and tracking procedures to enable the preparation of financial information on adoption. We did not elect the use-of-hindsight practical expedient, or the practical expedient pertaining to land easements as it was not applicable to us. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualified, primarily for leases that are month-to-month leases. This means, for those leases, we did not recognize right-of-use assets or lease liabilities. We also elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets. This standard had a material effect on our consolidated balance sheet relating to the recognition of an operating lease right-of-use asset and operating lease liability for our real estate leases and related to new disclosures about our leasing activities. On adoption, we recognized an operating lease right-of-use asset of $30.5 $32.3 6.2% Leases Accounting Policy We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liability, and operating lease liability, less current portion, on our consolidated balance sheets. Should we engage in any finance leases in the future, finance leases would be included in property and equipment, other current liabilities, and other liabilities on our consolidated balance sheets. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease right-of-use asset also includes any lease payments made and initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Recently Issued Accounting Pronouncements Fair Value Measurement Disclosures In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”. The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company does not believe that the adoption of this guidance will have a significant impact on its fair value disclosures. Financial Instruments – Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. ASU 2016-13 also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. Subsequently, in November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses”. ASU 2018-19 clarifies the codification and corrects unintended application of the guidance. ASU’s 2016-13 and 2018-19 are effective for us for our fiscal year beginning after December 15, 2019. We do not believe that the adoption of this guidance will have a significant impact on our consolidated financial statements. 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 doubtful accounts 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. Uncollectible accounts are written off after repeated attempts to collect from the customer have been unsuccessful. As of September 28, 2019, and December 29, 2018, the allowance for doubtful accounts was million and million, respectively.
Revenue Recognition Accounting Policy	Revenue Recognition Accounting Policy The Company primarily manufactures fully customized windows and doors, and manufactures products based on design specifications, measurements, colors, finishes, framing materials, glass-types, and other options selected by the customer at the point in time an order is received from the customer. The Company has an enforceable right to payment at the time an order is received and accepted at the agreed-upon sales prices contained in our agreements with our customers for all manufacturing efforts expended by the Company on behalf of its customers. Due to the customized build-to-order nature of the Company’s products, the Company’s assessment is that the substantial portion of its finished goods and certain unused glass components have no alternative use, and that control of these products and components passes to the customer over time during the manufacturing of the products in an order, or upon our receipt of certain pre-cut glass components from our supplier attributed to specific customer orders. Based on these factors, the Company recognizes a substantial portion of revenue over time during the manufacturing process once customization begins, and for certain unused glass components on hand, at the end of a reporting period. Revenue on work-in-process at the end of a reporting period is recognized in proportion to costs incurred to total estimated cost of the product being manufactured. Except for the Western segment’s volume products, discussed in the section titled Disaggregation of Revenue from Contracts with Customers below, revenue recognized at a point in time is immaterial.
Shipping and Handling Cost and Commissions on Contract Assets	Policies Regarding Shipping and Handling Costs and Commissions on Contract Assets The Company has made a policy election to continue to recognize shipping and handling costs as a fulfillment activity. Treating shipping and handling as a fulfillment activity requires estimated shipping and handling costs for undelivered products and certain glass components on which we have recognized revenue and created a contract asset, to be accrued to match this cost with the recognized revenue. This policy is unchanged from the Company’s policy for recognizing shipping and handling costs prior to the adoption of the new revenue guidance. The Company utilizes the practical expedient which permits expensing of costs to obtain a contract when the expected amortization period is one year or less, which typically results in expensing commissions paid to employees. We expense sales commissions paid to employees as sales are recognized, including sales from the creation of contract assets, as the expected amortization period is less than one year.
