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, Inc. and its wholly-owned subsidiary, PGT Industries, Inc., and its wholly-owned subsidiary CGI Window and Holdings, Inc. (collectively the “Company”), after elimination of intercompany accounts and transactions. These statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of 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 periods are not necessarily indicative of the results that may be expected for the remainder of the current year or for any future periods. Each of our Company’s fiscal quarters ended July 4, 2015 and June 28, 2014, consisted of 13 weeks. The condensed consolidated balance sheet as of January 3, 2015, is derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. The condensed consolidated balance sheet as of January 3, 2015, and the unaudited condensed consolidated financial statements as of and for the period ended July 4, 2015, should be read in conjunction with the more detailed audited consolidated financial statements for the year ended January 3, 2015, included in the Company’s most recent Annual Report on Form 10-K. 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. Recently Adopted Accounting Pronouncements In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of, or is classified as held for sale, and represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Major strategic shifts include disposals of a significant geographic area or line of business. The new standard allows an entity to have significant continuing involvement and cash flows with the discontinued operation. The standard requires expanded disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This new guidance is effective for annual reporting periods beginning on or after December 15, 2014, and interim periods within those annual periods, with early adoption permitted only for disposals (or classifications as held for sale) that have not been previously reported. The adoption of this standard did not have a significant impact on our consolidated financial statements.

Warranty

Warranty	6 Months Ended

Guarantees [Abstract]
Warranty	NOTE 2. 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 reserve 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 July 4, 2015, we recorded warranty expense at a rate of 2.25% of sales. This rate is higher than the 1.50% of sales accrued in the second quarter of 2014, due to an increase in warranty claims experience. 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 six months ended July 4, 2015, and June 28, 2014. The reserve is determined through specific identification and assessing Company history. Expected future obligations are discounted to a current value using a risk-free rate for obligations with similar maturities. The following provides information with respect to our warranty accrual: Beginning Charged End of Accrued Warranty of Period to Expense Adjustments Settlements Period (in thousands) Three months ended July 4, 2015 $ 3,608 $ 2,268 $ 58 $ (1,857 ) $ 4,077 Three months ended June 28, 2014 $ 2,656 $ 1,228 $ (236 ) $ (1,342 ) $ 2,306 Six months ended July 4, 2015 $ 3,302 $ 4,176 $ 247 $ (3,648 ) $ 4,077 Six months ended June 28, 2014 $ 2,666 $ 2,326 $ (146 ) $ (2,540 ) $ 2,306

We have limited finished goods inventory since all products are custom, made-to-order and usually ship upon completion. Finished goods inventory costs include direct materials, direct labor, and overhead. All inventories are stated at the lower of cost (first-in, first-out method) or market value.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based-Compensation	NOTE 4. STOCK BASED-COMPENSATION Exercises For the three months ended July 4, 2015, there were 750,640 options exercised at a weighted average exercise price of $2.05 per share. For the six months ended July 4, 2015, there were 768,340 options exercised at a weighted average exercise price of $2.05 per share. Issuance On March 4, 2015, we granted 178,256 restricted stock awards to certain executives and non-executive employees of the Company. 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 89,128 shares, is fixed, whereas the quantity granted on the remaining half, or 89,128 shares, is subject to Company-specific performance criteria. The restricted stock awards have a fair value on date of grant of $10.95 per share based on the closing NASDAQ market price of the common stock on the day prior to 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 over a two-year period on the second and third anniversary dates of the grant. 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 2015 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 original amount of shares. We record stock compensation expense over an 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 $0.5 million for the three months ended July 4, 2015 and $0.4 million for the three months ended June 28, 2014. We recorded compensation expense for stock based awards of $0.9 million for the six months ended July 4, 2015 and $0.6 million for the six months ended June 28, 2014. As of July 4, 2015, and June 28, 2014, there was $2.2 million and $1.9 million, respectively, of total unrecognized compensation cost related to non-vested stock option agreements and restricted share awards. These costs are expected to be recognized in earnings on a straight-line basis over the weighted average remaining vesting period of 1.8 years at July 4, 2015, and 1.8 years at June 28, 2014.

Earnings Per Share [Abstract]
Net Income Per Common Share	NOTE 5. NET INCOME PER COMMON SHARE Basic EPS is computed by dividing net income available to common shareholders, by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the dilutive effect of potential common shares from securities such as stock options. Weighted average shares outstanding for the three months ended July 4, 2015, and June 28, 2014, excludes underlying options and restricted stock awards of 20 thousand and 164 thousand, respectively, because their effects were anti-dilutive. Weighted average shares outstanding for the six months ended July 4, 2015, and June 28, 2014, excludes underlying options and restricted stock awards of 20 thousand and 106 thousand, respectively, because their effects were anti-dilutive. The table below presents the calculation of EPS and a reconciliation of weighted average common shares used in the calculation of basic and diluted EPS for our Company: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, 2015 2014 2015 2014 (in thousands, except per share amounts) Net income $ 6,780 $ 7,801 $ 13,432 $ 11,153 Weighted-average common shares—Basic 48,077 47,265 47,899 47,207 Add: Dilutive effect of stock compensation plans 2,206 2,441 2,256 2,509 Weighted-average common shares—Diluted 50,283 49,706 50,155 49,716 Net income per common share: Basic $ 0.14 $ 0.17 $ 0.28 $ 0.24 Diluted $ 0.13 $ 0.16 $ 0.27 $ 0.22

Business Combinations [Abstract]
Acquisition	NOTE 6. ACQUISITION On September 22, 2014, we completed the acquisition of CGI which became a wholly-owned subsidiary of PGT, Inc. The purchase price paid in the transaction was $110.4 million, which was preliminarily allocated to the net assets acquired and liabilities assumed as of the acquisition date, in accordance with ASC 805, “Business Combinations”. There have been no adjustments to this preliminary allocation in the three or six months ended July 4, 2015. For discussion of this acquisition, see Note 4 in the Company’s Annual Report on Form 10-K for the year ended January 3, 2015. The following unaudited pro forma financial information assumes the acquisition had occurred at the beginning of the earliest period presented that does not include CGI’s actual results for the entire period. Pro forma results have been prepared by adjusting our historical results to include the results of CGI adjusted for the following: amortization expense related to the intangible assets arising from the acquisition and interest expense to reflect the 2014 Credit Agreement entered into in connection with the acquisition. The unaudited pro forma results below do not necessarily reflect the results of operations that would have resulted had the acquisition been completed at the beginning of the earliest periods presented, nor does it indicate the results of operations in future periods. The unaudited pro forma results do not include the impact of synergies, nor any potential impacts on current or future market conditions which could alter the following unaudited pro forma results.

Debt Disclosure [Abstract]
Long-Term Debt	NOTE 8. LONG-TERM DEBT On September 22, 2014, we entered into a Credit Agreement (the “2014 Credit Agreement”), among us, the lending institutions identified in the 2014 Credit Agreement, and Deutsche Bank AG New York Branch, as Administrative Agent and Collateral Agent. For further discussion of the significant terms of the 2014 Credit Agreement, see Note 8 in the Company’s Annual Report on Form 10-K for the year ended January 3, 2015. As of July 4, 2015, there were $0.5 million of letters of credit outstanding and $34.5 million available under the revolving credit portion of the 2014 Credit Agreement. The 2014 Credit Agreement contains a springing financial covenant, if we draw in excess of twenty percent (20%) of the revolving facility, which requires us to maintain a maximum total net leverage ratio (based on the ratio of total debt for borrowed money to trailing EBITDA, each as defined in the 2014 Credit Agreement), and is tested quarterly based on the last four fiscal quarters and is set at levels as described in the 2014 Credit Agreement. As of July 4, 2015, no such test is required as we have not exceeded 20% of our revolving capacity. The 2014 Credit Agreement 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, prepayments of certain debt and transactions with affiliates. The 2014 Credit Agreement also contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the 2014 Credit Agreement may be accelerated and may become due and payable. The face value of the debt as of July 4, 2015, was $198.5 million. Related debt issuance costs and the debt discount are being amortized to interest expense, net on the condensed consolidated statements of comprehensive income over the term of the debt. The contractual future maturities of long-term debt outstanding as of July 4, 2015, are as follows (excluding unamortized debt discount and issuance costs): (in thousands) 2015 $ 1,000 2016 2,000 2017 2,000 2018 2,000 2019 2,000 Thereafter 189,500 Total $ 198,500

Income Taxes	NOTE 11. INCOME TAXES Income tax expense was $6.3 million for the three months ended July 4, 2015, compared with $4.8 million for the three months ended June 28, 2014. Our effective tax rate for the three months ended July 4, 2015, was 48.2%, and was 38.0% for the three months ended June 28, 2014. Income tax expense for the six months ended July 4, 2015, was $10.0 million, compared with $6.7 million for the six months ended June 28, 2014. Our effective tax rate for the six months ended July 4, 2015, was 42.8%, and was 37.7% for the six months ended June 28, 2014. Income tax expense in both the three and six month periods ended July 4, 2015, includes a $1.6 million discrete item of income tax expense representing income tax expense previously classified within accumulated other comprehensive losses, relating to the intraperiod income taxes on our effective aluminum hedges, allocated to other comprehensive income in the year ended January 2, 2010, which we reversed in the three months ended July 4, 2015, as the result of the culmination of our remaining cash flow hedges. Excluding this discrete item of income tax expense, the effective tax rate for the three and six month periods ended July 4, 2015, would have been 36.0% and 36.0%, respectively. The effective tax rates in all periods of both 2015, excluding the effect of the discrete income tax item, and 2014, were lower than our combined statutory federal and state tax rate of 38.8% as the result of the estimated impact of the section 199 domestic manufacturing deduction.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 12. DERIVATIVES Derivative Financial Instruments – Aluminum Contracts We enter into aluminum forward contracts to hedge the fluctuations in the purchase price of aluminum extrusion we use in production. Certain of 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. For further discussion of our derivative financial instruments relating to aluminum contracts, see Note 9 in the Company’s Annual Report on Form 10-K for the year ended January 3, 2015. We maintain a $2.0 million line of credit with our commodities broker to cover the liability position of open contracts for the purchase of aluminum in the event that the price of aluminum falls. Should the price of aluminum fall to a level which causes our liability for open aluminum contracts to exceed $2.0 million, we are required to fund daily margin calls to cover the excess. As of July 4, 2015, no amounts were borrowed under this line of credit. At July 4, 2015, the fair value of our aluminum forward contracts was in a net liability position of $278 thousand. We had 5 outstanding forward contracts for the purchase of 1.9 million pounds of aluminum through December 2015, at an average price of $0.93 per pound, which excludes the Midwest premium, with maturity dates of between 1 month and 5 months. We assessed the risk of non-performance of the Company to these contracts and recorded a de minimis adjustment to fair value as of July 4, 2015. Although it is our intent to have our aluminum hedges qualify as highly effective for reporting purposes, for the three and six months ended July 4, 2015, and June 28, 2014, certain of our outstanding contracts did not qualify as effective. In the case of our 5 outstanding contracts as of July 4, 2015, these contracts were never evaluated for or considered as qualifying for accounting as cash flow hedges. Effectiveness of aluminum forward contracts is determined 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. When a cash flow hedge becomes ineffective, and if the forecasted hedged transaction is still probable of occurrence, amounts previously recorded in accumulated other comprehensive loss remain in accumulated other comprehensive loss and are recognized in earnings in the period in which the hedged transaction affects earnings. The changes in value of the aluminum forward contracts occurring after ineffectiveness and the contracts that had not been evaluated for or considered as qualifying for accounting as cash flow hedges, are recognized in other expense, net, on the condensed consolidated statements of comprehensive income, and totaled other expenses of $125 thousand and other income of $290 thousand for the three months ended July 4, 2015, and June 28, 2014, respectively, and other expenses of $224 thousand and other income of $128 thousand for the six months ended July 4, 2015, and June 28, 2014, respectively. As of July 4, 2015, we have no remaining accumulated other comprehensive income or loss. Derivative Financial Instruments – Interest Rate Contract We have an interest rate cap agreement we entered into on September 16, 2013. It is a two-year agreement with a notional amount of $20.0 million; and was initially designated as a cash flow hedge to protect the variable rate debt from an increase in the floating, one-month LIBOR rate of greater than 0.50%. Upon entering into the 2014 Credit Agreement, effective on September 22, 2014, it was de-designated as a cash flow hedge and has since been marked-to-market in other expense, net, on the condensed consolidated statements of comprehensive income, and were de minimis for the three and six months ended July 4, 2015, and June 28, 2014, respectively.

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 the condensed consolidated statements of comprehensive income. 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 make the election on an instrument-by-instrument basis as they are acquired or incurred. Items Measured at Fair Value on a Recurring Basis The following assets and liabilities are measured in the condensed consolidated balance sheets 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 July 4, Markets Inputs Inputs Description 2015 (Level 1) (Level 2) (Level 3) Aluminum forward contracts $ (278 ) $ — $ (278 ) $ — Interest rate cap — — — — $ (278 ) $ — $ (278 ) $ — Description January Quoted (Level 1) Significant Significant Aluminum forward contracts $ (491 ) $ — $ (491 ) $ — Interest rate cap 2 — 2 — $ (489 ) $ — $ (489 ) $ — The following is a description of the methods and assumptions used to estimate the fair values of our 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. Interest rate cap and swap contracts identical to that held by us are sold by financial institutions. The valuation price at any measurement date for a contract with identical terms, exercise price, expiration date, settlement date, and notional quantities, as the one we hold, is used for determining the fair value. Fair Value of Financial Instruments The following table presents the carrying values and estimated fair values of financial assets and liabilities that are required to be recorded or disclosed at fair value at July 4, 2015, and January 3, 2015 (in thousands): July 4, 2015 January 3, 2015 Carrying Estimated Value Carrying Estimated Value Financial assets (liabilities) Cash and cash equivalents $ 47,487 $ 47,487 $ 42,469 $ 42,469 Accounts receivable, net $ 37,638 $ 37,638 $ 25,374 $ 25,374 Accounts payable and accrued liabilities $ (21,524 ) $ (21,524 ) $ (17,328 ) $ (17,328 ) Long-term debt (including current portion) $ (193,090 ) $ (193,090 ) $ (193,754 ) $ (193,754 ) The following provides a description of the methods and significant assumptions used in estimating the fair value of our financial instruments that are not measured at fair value on a recurring basis.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of, or is classified as held for sale, and represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Major strategic shifts include disposals of a significant geographic area or line of business. The new standard allows an entity to have significant continuing involvement and cash flows with the discontinued operation. The standard requires expanded disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This new guidance is effective for annual reporting periods beginning on or after December 15, 2014, and interim periods within those annual periods, with early adoption permitted only for disposals (or classifications as held for sale) that have not been previously reported. The adoption of this standard did not have a significant impact on our consolidated financial statements.
