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 million, and an operating lease liability of $32.3 million, based on the present value of the remaining minimum rental payments under prior leasing standards for existing operating leases. Calculation of the present value of the remaining minimum rental payments required the use of judgment relating to the selection of the discount rate applied to future lease payments. We used a weighted-average interest rate of 6.2%, which was based on a current trade rate for our 2018 Senior Notes due 2026. See Note 10 for additional information relating to our leases. 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 $3.7 million and $2.8 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.
