Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2017, or state and local income tax examinations for years prior to fiscal 2013. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2016, and there is limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions. The total liability for unrecognized tax benefits was $4.2 million and $4.1 million at August 29, 2020 and February 29, 2020, respectively. Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. The total liability for unrecognized tax benefits is expected to decrease by approximately $0.4 million during the next 12 months due to lapsing of statutes.

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 February 29, 2020. We use the same accounting policies in preparing quarterly and annual financial statements. All adjustments necessary for a fair presentation of quarterly and year to date operating results are reflected herein and are of a normal, recurring nature. The results of operations for the three- and six-month periods ended August 29, 2020 are not necessarily indicative of the results to be expected for the full year. COVID-19 considerations The ongoing COVID-19 pandemic continues to cause volatility and uncertainty in global markets impacting worldwide economic activity. We have experienced some delays in commercial construction projects and orders as a result of COVID-19. In our Architectural Glass and Architectural Framing segments, orders have been delayed or have slowed, as customers and end markets face some uncertainty and delays in timing of work. In our Architectural Services segment, some construction site closures or project delays have occurred, and job sites have had to adjust to increased physical distancing and health-related precautions. Within our Large-Scale Optical (LSO) segment, many customers reopened and the segment's two manufacturing locations resumed normal operations during the second quarter, after being shutdown for most of the first and second quarters, in response to governmental “stay at home” directives. We have also been impacted by quarantine-related absenteeism among our workforce, resulting in labor and capacity constraints at some of our facilities. The extent to which COVID-19 will continue to impact our business will depend on future developments and public health advancements, which are highly uncertain and cannot be predicted with confidence. However, by the end of the second quarter, we have continued to see signs of improvement, including the reopening of retailers, moderating project delays and fewer workforce absences. Furthermore, in response to COVID-19, we have implemented a variety of countermeasures to promote the health and safety of our employees during this pandemic, including health screening, physical distancing practices, enhanced cleaning, use of personal protective equipment, business travel restrictions, and remote work capabilities, in addition to quarantine-related paid leave and other employee assistance programs. Adoption of new accounting standards At the beginning of fiscal 2021, we adopted the guidance in ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The guidance provides for a new impairment model on financial instruments which is based on expected credit losses, which was applied following a modified retrospective approach. Additionally, the new guidance makes targeted improvements to the impairment model for certain available-for-sale debt securities, including eliminating the concept of "other than temporary" from that model. The portion of the guidance related to available-for-sale debt securities was adopted following a prospective approach. The adoption of this ASU did not have a significant impact on earnings or financial condition. Refer to additional disclosures in Notes 2 and 4. Subsequent events We have evaluated subsequent events for potential recognition and disclosure through the date of this filing. Subsequent to the end of the quarter, in September 2020, we sold our McCook, IL building within our LSO segment for $25.1 million. The carrying value of the building was $4.3 million, and we recognized a gain on this sale of approximately $14.8 million, net of taxes and associated transaction costs. We also entered into a separate lease agreement for this facility, which was determined to be an operating lease, and we will have approximately $8.2 million of additional future lease commitments upon commencement of this lease in September 2020. Additionally, in September 2020, we announced the retirement of our Chief Executive Officer, effective February 27, 2021, the end of our current fiscal year, and entered into a transition agreement with him.

Revenue, Receivables and Contract Assets and Liabilities	Revenue, Receivables and Contract Assets and Liabilities Revenue The following table disaggregates total revenue by timing of recognition (see Note 12 for disclosure of revenue by segment): Three Months Ended Six Months Ended (In thousands) August 29, 2020 August 31, 2019 August 29, 2020 August 31, 2019 Recognized at shipment $ 133,997 $ 164,336 $ 250,160 $ 319,602 Recognized over time 185,486 192,722 358,418 392,822 Total $ 319,483 $ 357,058 $ 608,578 $ 712,424 Receivables Receivables reflected in the financial statements represent the net amount expected to be collected. An allowance for credit losses is established based on expected losses. Expected losses are estimated by reviewing individual accounts, considering aging, financial condition of the debtor, recent payment history, current and forecast economic conditions and other relevant factors. Upon billing, aging of receivables is monitored until collection. An account is considered current when it is within agreed upon payment terms. An account is written off when it is determined that the asset is no longer collectible. 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.

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.

As of August 29, 2020, the interest rate swap contract had a notional value of $60 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 August 29, 2020, we held foreign exchange forward contracts with a U.S. dollar notional value of $28.4 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).

Commercial paper was measured at fair value using inputs based on quoted prices for similar securities in active markets. These assets are included within cash and cash equivalents on our consolidated balance sheets. Municipal and corporate bonds Municipal and corporate bonds were measured at fair value based on market prices from recent trades of similar securities and are classified within our consolidated balance sheets as other current or other non-current assets based on maturity date. Cash surrender value of life insurance and deferred compensation Contracts insuring the lives of certain employees who are eligible to participate in certain non-qualified pension and deferred compensation plans are held in trust. Cash surrender value of the contracts is based on performance measurement funds that shadow the deferral investment allocations made by participants in certain deferred compensation plans. Changes in cash surrender value are recorded in other expense. The deferred compensation liability balances are valued based on amounts allocated by participants to the underlying performance measurement funds. Derivative instruments

Debt Disclosure [Abstract]
Debt	DebtAs of August 29, 2020, we had a committed revolving credit facility with maximum borrowings of up to $235 million, maturing in June 2024, and a $150 million term loan maturing in April 2021. As of August 29, 2020, our total debt outstanding was $167.7 million, compared to $217.9 million as of February 29, 2020. There were no outstanding borrowings under the revolving credit facility as of August 29, 2020, and there were $47.5 million in outstanding borrowings under the revolving credit facility as of February 29, 2020. Our revolving credit facility and term loan contain 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 August 29, 2020, we were in compliance with both financial covenants. Additionally, at August 29, 2020, we had a total of $18.7 million of ongoing letters of credit related to industrial revenue bonds, construction contracts and insurance collateral that expire in fiscal years 2021 to 2022 and reduce borrowing capacity under the revolving credit facility. At August 29, 2020, debt included $15.0 million of industrial revenue bonds that mature in fiscal years 2022 through 2043. In June 2020, a $5.4 million industrial revenue bond matured and was repaid. The fair value of the industrial revenue bonds approximated carrying value at August 29, 2020, 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 committed, revolving credit facilities totaling $25.0 million (USD). As of August 29, 2020, $2.7 million in borrowings were outstanding under the facilities, while at February 29, 2020, no borrowings were outstanding under the facilities. Interest payments were $2.5 million and $5.3 million for the six months ended August 29, 2020 and August 31, 2019, respectively.

Leases [Abstract]
Leases	7. 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 non lease 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 Six Months Ended (In thousands) August 29, 2020 August 31, 2019 August 29, 2020 August 31, 2019 Operating lease cost $ 3,290 $ 3,490 $ 6,851 $ 6,863 Short-term lease cost 442 496 912 1,179 Variable lease cost 645 667 1,392 1,380 Total lease cost $ 4,377 $ 4,653 $ 9,155 $ 9,422 Other supplemental information related to leases was as follows: Six Months Ended (In thousands except weighted-average data) August 29, 2020 August 31, 2019 Cash paid for amounts included in the measurement of operating lease liabilities $ 6,562 $ 6,791 Lease assets obtained in exchange for new operating lease liabilities $ 6,778 $ 8,970 Weighted-average remaining lease term - operating leases 4.9 years 6.0 years Weighted-average discount rate - operating leases 3.55 % 3.70 % Future maturities of lease liabilities are as follows: (In thousands) August 29, 2020 Remainder of Fiscal 2021 $ 6,443 Fiscal 2022 12,081 Fiscal 2023 11,081 Fiscal 2024 9,122 Fiscal 2025 7,307 Fiscal 2026 6,062 Thereafter 8,686 Total lease payments 60,782 Less: Amounts representing interest (5,185) Present value of lease liabilities $ 55,597

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 August 29, 2020, $1.1 billion of these types of bonds were outstanding, of which $589.1 million is in 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: Six Months Ended (In thousands) August 29, 2020 August 31, 2019 Balance at beginning of period $ 15,629 $ 16,737 Additional accruals 3,083 3,606 Claims paid (2,050) (5,481) Balance at end of period $ 16,662 $ 14,862 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. The liability for these types of project-related contingencies was $8.7 million and $49.0 million as of August 29, 2020 and February 29, 2020, respectively. In June 2020, we settled contract claims related to a majority of these project-related contingencies on a legacy EFCO project for an amount equal to the contingency recorded at May 30, 2020. Letters of credit At August 29, 2020, we had $18.7 million of ongoing letters of credit, all of which have been issued under our committed revolving credit facility, as discussed in Note 6. In connection with the settlement of contract claims related to a legacy EFCO project referenced above, the original project performance and payment bond related to the project was replaced, which required a $25.0 million letter of credit. The letter of credit for the replacement bond was issued outside of our committed revolving credit facility, with no impact on our borrowing capacity and debt covenants. Purchase obligations Purchase obligations for raw material commitments and capital expenditures totaled $180.9 million as of August 29, 2020. New Markets Tax Credit (NMTC) transactions We have entered into four separate NMTC programs to support our operational expansion. 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 November 2020 $ 10.7 $ 3.3 $ 7.4 June 2016 June 2023 6.0 1.2 4.8 August 2018 August 2025 6.6 1.3 5.3 September 2018 September 2025 3.2 1.0 2.2 Total $ 26.5 $ 6.8 $ 19.7 Litigation 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Impact of new accounting guidance		Adoption of new accounting standards At the beginning of fiscal 2021, we adopted the guidance in ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The guidance provides for a new impairment model on financial instruments which is based on expected credit losses, which was applied following a modified retrospective approach. Additionally, the new guidance makes targeted improvements to the impairment model for certain available-for-sale debt securities, including eliminating the concept of "other than temporary" from that model. The portion of the guidance related to available-for-sale debt securities was adopted following a prospective approach. The adoption of this ASU did not have a significant impact on earnings or financial condition. Refer to additional disclosures in Notes 2 and 4.
Subsequent Events	Subsequent events We have evaluated subsequent events for potential recognition and disclosure through the date of this filing. Subsequent to the end of the quarter, in September 2020, we sold our McCook, IL building within our LSO segment for $25.1 million. The carrying value of the building was $4.3 million, and we recognized a gain on this sale of approximately $14.8 million, net of taxes and associated transaction costs. We also entered into a separate lease agreement for this facility, which was determined to be an operating lease, and we will have approximately $8.2 million of additional future lease commitments upon commencement of this lease in September 2020. Additionally, in September 2020, we announced the retirement of our Chief Executive Officer, effective February 27, 2021, the end of our current fiscal year, and entered into a transition agreement with him.
