Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation The consolidated financial statements of Apogee Enterprises, Inc. (we, us, our or the Company) have been prepared in accordance with accounting principles generally accepted in the United States. The information included in this Form 10-Q should be read in conjunction with the Company’s Form 10-K for the year ended March 2, 2019 . We use the same accounting policies in preparing quarterly and annual financial statements. All adjustments necessary for a fair presentation of quarterly operating results are reflected herein and are of a normal, recurring nature. The results of operations for the nine -month period ended November 30, 2019 are not necessarily indicative of the results to be expected for the full year. Adoption of new accounting standards At the beginning of fiscal 2020, we adopted the guidance in ASC 842, Leases , following a modified retrospective approach and elected not to restate prior periods. Adoption of the new standard resulted in recording operating lease assets and liabilities of approximately $50 million as of March 3, 2019 and did not materially impact our consolidated net earnings and cash flows. Refer to additional information in Note 7. Accounting standards not yet adopted In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments , which revises guidance for the accounting for credit losses on financial instruments within its scope. The new standard introduces an approach based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. This ASU is effective for our fiscal year 2021. Entities are required to apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We do not expect the adoption of this ASU to have a significant impact on our consolidated financial statements. Subsequent events

The amounts due are stated at their estimated net realizable value. We maintain an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. This allowance is based on an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables. Retainage on construction contracts represents amounts withheld by our customers on long-term projects until the project reaches a level of completion where amounts are released. In thousands November 30, 2019 March 2, 2019 Trade accounts $ 141,448 $ 145,693 Construction contracts 23,096 19,050 Contract retainage 35,287 32,396 Total receivables 199,831 197,139 Less: allowance for doubtful accounts (1,855 ) (4,372 ) Net receivables $ 197,976 $ 192,767 Contract assets and liabilities Contract assets consist of retainage, costs and earnings in excess of billings and other unbilled amounts typically generated when revenue recognized exceeds the amount billed to the customer. Contract liabilities consist of billings in excess of costs and earnings and other deferred revenue on contracts. Retainage is classified within receivables and deferred revenue is classified within other current liabilities on our consolidated balance sheets. The time period between when performance obligations are complete and when payment is due is not significant. In certain of our businesses that recognize revenue over time, progress billings follow an agreed-upon schedule of values, and retainage is withheld by the customer until the project reaches a level of completion where amounts are released. In thousands November 30, 2019 March 2, 2019 Contract assets $ 107,571 $ 87,491 Contract liabilities 28,863 24,083 The increase in contract assets was due to timing of costs incurred in advance of billings, primarily on a legacy EFCO project. The change in contract liabilities was due to timing of project activity within our businesses that operate under long-term contracts.

As of November 30, 2019 , the transaction price associated with unsatisfied performance obligations was approximately $896.7 million .

As of November 30, 2019 , the interest rate swap contract had a notional value of $85 million . We periodically enter into forward purchase foreign currency cash flow hedge contracts, generally with an original maturity date of less than one year, to hedge foreign currency exchange rate risk. As of November 30, 2019 , we held foreign exchange forward contracts with a U.S. dollar notional value of $24.7 million , with the objective of reducing the exposure to fluctuations in the Canadian dollar and the Euro. These derivative instruments are recorded within our consolidated balance sheets within other current assets and liabilities. Gains or losses associated with these instruments are recorded as a component of accumulated other comprehensive income. Fair value measurements Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data).

Debt Disclosure [Abstract]
Debt	Debt As of November 30, 2019 , our total debt outstanding was $251.3 million , compared to $245.8 million as of March 2, 2019. During the second quarter of fiscal 2020, we amended the borrowing capacity of our prior credit facility to $235 million with a maturity of June 2024 and we established a $150 million term loan with a maturity of June 2020 . Outstanding borrowings under the revolving credit facility were $80.5 million , as of November 30, 2019 , and $225.0 million , as of March 2, 2019 . Our revolving credit facility and term loan contains two financial covenants that require us to stay below a maximum debt-to-EBITDA ratio and maintain a minimum ratio of interest expense-to-EBITDA. Both ratios are computed quarterly, with EBITDA calculated on a rolling four-quarter basis. At November 30, 2019 , we were in compliance with both financial covenants. Additionally, at November 30, 2019 , we had a total of $24.7 million of ongoing letters of credit related to industrial revenue bonds, construction contracts and insurance collateral that expire in fiscal years 2021 to 2032 and reduce borrowing capacity under the revolving credit facility. At November 30, 2019 , debt included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043 and $0.4 million of long-term debt in Canada. The fair value of the industrial revenue bonds approximated carrying value at November 30, 2019 , due to the variable interest rates on these instruments. All debt would be classified as Level 2 within the fair value hierarchy described in Note 4. We also maintain two Canadian demand credit facilities totaling $ 12.0 million Canadian dollars. As of November 30, 2019 and March 2, 2019 , no borrowings were outstanding under the facilities. Borrowings under these facilities are made available at the sole discretion of the lenders and are payable on demand. Interest payments were $7.3 million and $7.2 million for the nine months ended November 30, 2019 and December 1, 2018 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Bond commitments In the ordinary course of business, predominantly in our Architectural Services and Architectural Framing Systems segments, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At November 30, 2019 , $833.9 million of these types of bonds were outstanding, of which $432.6 million is on our backlog. These bonds do not have stated expiration dates. We have never been required to make payments under surety or performance bonds with respect to our existing businesses. Warranty and project-related contingencies We reserve estimated exposures on known claims, as well as on a portion of anticipated claims, for product warranty and rework cost, based on historical product liability claims as a ratio of sales. Claim costs are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, changes in product mix and any significant changes in sales volume. A warranty rollforward follows: Nine Months Ended In thousands November 30, 2019 December 1, 2018 Balance at beginning of period $ 16,737 $ 22,517 Additional accruals 5,996 3,437 Claims paid (7,807 ) (8,398 ) Balance at end of period $ 14,926 $ 17,556 Additionally, we are subject to project management and installation-related contingencies as a result of our fixed-price material supply and installation service contracts, primarily in our Architectural Services segment and certain of our Architectural Framing Systems businesses. We manage the risk of these exposures through contract negotiations, proactive project management and insurance coverages. We have recorded an estimated liability related to a legacy EFCO project of $47.6 million and $42.8 million as of November 30, 2019 and March 2, 2019 , respectively. This includes approximately $14.7 million recorded in the third quarter for estimated costs associated with project dispute resolution and other additional project costs. In the third quarter, upon confirmation of coverage by an insurer, we also recorded an insurance receivable of $15.0 million , included within other current assets on the consolidated balance sheets and within cost of sales on the consolidated results of operations. We received this payment subsequent to quarter-end. Letters of credit At November 30, 2019 , we had $24.7 million of ongoing letters of credit, all of which have been issued under our committed revolving credit facility, as discussed in Note 6. Purchase obligations Purchase obligations for raw material commitments and capital expenditures totaled $146.0 million as of November 30, 2019 . New Markets Tax Credit (NMTC) transactions We have entered into four separate NMTC programs to support our operational expansion, including two transactions completed in fiscal 2019 . Proceeds received from investors on these transactions are included within other current and non-current liabilities on our consolidated balance sheets. The NMTC arrangements are subject to 100 percent tax recapture for a period of seven years from the date of each respective transaction. Therefore, upon the termination of each arrangement, these proceeds will be recognized in earnings in exchange for the transfer of tax credits. The direct and incremental costs incurred in structuring these arrangements have been deferred and are included in other current and non-current assets on our consolidated balance sheets. These costs will be recognized in conjunction with the recognition of the related proceeds on each arrangement. During the construction phase, we are required to hold cash dedicated to fund each capital project which is classified as restricted cash on our consolidated balance sheets. Variable-interest entities, which have been included within our consolidated financial statements, have been created as a result of the structure of these transactions, as investors in the programs do not have a material interest in their underlying economics. The table below provides a summary of our outstanding NMTC transactions (in millions): Inception date Termination date Proceeds received Deferred costs Net benefit November 2013 October 2020 $ 10.7 $ 3.0 $ 7.7 June 2016 May 2023 6.0 0.9 5.1 August 2018 July 2025 6.6 0.9 5.7 September 2018 August 2025 3.2 0.8 2.4 Total $ 26.5 $ 5.6 $ 20.9 Litigation On November 5, 2018, a shareholder filed a purported securities class action against the Company and certain named executive officers. On April 26, 2019, the new lead plaintiff filed an amended complaint, alleging that, during the purported class period of May 1, 2017 to April 10, 2019, the Company and the named executive officers made materially false or misleading statements or omissions about the Company's acquisition of EFCO Corporation on June 12, 2017, and about the Company's Architectural Glass business segment, in violation of the federal securities laws. We intend to vigorously defend this matter. On December 17, 2018, a different shareholder filed a derivative lawsuit, purportedly on behalf of the Company, against certain of our executive officers and directors claiming breaches of fiduciary duty, waste of corporate assets and unjust enrichment. This complaint alleges that the officers and directors allegedly made materially false or misleading statements or omissions about the Company's business, operations and prospects, particularly with respect to our Architectural Glass business segment, during the period between June 28, 2018 and September 17, 2018. This matter has been stayed, pending resolution of a motion to dismiss the foregoing matter. We intend to vigorously defend this matter. In addition to the foregoing, the Company is a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company is routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is also subject to litigation arising out of areas such as employment practices, workers compensation and general liability matters. Although it is very difficult to accurately predict the outcome of any such proceedings, facts currently available indicate that no matters will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.

Leases [Abstract]
Leases	Leases We lease certain of the buildings and equipment used in our operations. We determine if an arrangement contains a lease at inception. Currently, all of our lease arrangements are classified as operating leases. We elected the package of practical expedients permitted under the transition guidance in adopting ASC 842, which among other things, allowed us to carry forward our historical lease classification. Operating lease assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term and lease expense is recognized on a straight-line basis over the lease term. Our leases have remaining lease terms of one to ten years, some of which include renewal options that can extend the lease for up to an additional ten years at our sole discretion. We have made an accounting policy election not to record leases with an original term of 12 months or less on our consolidated balance sheet and such leases are expensed on a straight-line basis over the lease term. In determining lease asset value, we consider fixed or variable payment terms, prepayments, incentives, and options to extend, terminate or purchase. Renewal, termination or purchase options affect the lease term used for determining lease asset value only if the option is reasonably certain to be exercised. We use a discount rate for each lease based upon an estimated incremental borrowing rate over a similar term. We have elected the practical expedient to account for lease and nonlease components (e.g., common-area maintenance costs) as a single lease component. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We are not a lessor in any transactions. The components of lease expense were as follows: Three Months Ended Nine Months Ended In thousands November 30, 2019 November 30, 2019 Operating lease cost $ 3,445 $ 10,308 Short-term lease cost 427 1,606 Variable lease cost 843 2,223 Total lease cost $ 4,715 $ 14,137 Other supplemental information related to leases was as follows: Nine Months Ended In thousands except weighted-average data November 30, 2019 Cash paid for amounts included in the measurement of operating lease liabilities $ 10,335 Lease assets obtained in exchange for new operating lease liabilities $ 15,948 Weighted-average remaining lease term - operating leases 5.9 years Weighted-average discount rate - operating leases 3.57 % Future maturities of lease liabilities are as follows: In thousands November 30, 2019 Remainder of Fiscal 2020 $ 3,366 Fiscal 2021 12,880 Fiscal 2022 11,256 Fiscal 2023 10,307 Fiscal 2024 8,147 Fiscal 2025 6,290 Thereafter 12,357 Total lease payments 64,603 Less: Amounts representing interest (6,695 ) Present value of lease liabilities $ 57,908 As of November 30, 2019 , we have no additional future operating lease commitments for leases that have not yet commenced.
