Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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 27, 2016 . 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. Certain prior year amounts have been reclassified for consistency with the current period presentation. The results of operations for the six -month period ended August 27, 2016 are not necessarily indicative of the results to be expected for the full year. In connection with preparing the unaudited consolidated financial statements for the six months ended August 27, 2016 , we evaluated subsequent events for potential recognition and disclosure through the date of this filing and determined there were no items to recognize or disclose.

New Accounting Standards

Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17, Balance Sheet Classification of Deferred Taxes , which requires all deferred tax assets and liabilities, along with any related valuation allowance, to be classified as noncurrent on the balance sheet. We early adopted this standard in the first quarter of the current fiscal year, and prior periods were not retrospectively adjusted. The adoption of this standard did not have a significant impact to our consolidated financial statements in any period presented. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes and statutory tax withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016. We will adopt this standard in the first quarter of our fiscal year 2018 and do not expect it to have a significant impact to our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , which provides for comprehensive changes to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, with a modified retrospective transition. We are currently evaluating the impact this standard will have on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2017, Apogee's fiscal 2019. We are currently evaluating the impact this standard will have on our consolidated financial statements.

We have a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism), which holds municipal bonds. Prism insures a portion of our general liability, workers’ compensation and automobile liability risks using reinsurance agreements to meet statutory requirements. The reinsurance carrier requires Prism to maintain fixed-maturity investments, which are generally high-quality municipal bonds, for the purpose of providing collateral for Prism’s obligations under the reinsurance agreement. As of August 27, 2016 , marketable securities with a fair value of $1.2 million have been in a continuous unrealized loss position for more than 12 months with unrea lized losses of $0.1 million . We test for other-than-temporary losses on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount of an investment may not be recoverable. We consider the unrealized losses indicated above to be temporary in nature. We intend to hold our investments until the full principal amount can be recovered, and we have the ability to do so based on other sources of liquidity. The amortized cost and estimated fair values of municipal bonds at August 27, 2016 , by contractual maturity, are shown below. Expected maturities may differ from contractual maturities, as borrowers may have the right to call or prepay obligations with or without penalty.

Debt Disclosure [Abstract]
Debt	Debt Debt at August 27, 2016 consisted of $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043. The fair value of the industrial revenue bonds approximates carrying value at August 27, 2016 , due to the variable interest rates on these instruments. The bonds would be classified as Level 2 within the fair value hierarchy described in Note 7. We maintain a $125.0 million committed revolving credit facility that expires in December 2019 . No borrowings were outstanding under the facility as of August 27, 2016 or February 27, 2016 . As defined within our committed revolving credit facility, we are required to comply with two financial covenants. These financial covenants require us to stay below a maximum debt-to-EBITDA ratio and maintain a minimum net worth. At August 27, 2016 , we were in compliance with both financial covenants. We also maintain a $ 4.0 million Canadian dollar revolving demand facility available to our Canadian operation. No borrowings were outstanding under this facility as of August 27, 2016 or February 27, 2016 . Borrowings under the facility are made available at the sole discretion of the lender and are payable on demand, with interest at rates specified in the credit agreement. Interest payments were $0.3 million for each of the six months ended August 27, 2016 and August 29, 2015 .

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 2013, or U.S. state and local income tax examinations for years prior to fiscal 2009. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2012, and there is very 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 at August 27, 2016 and February 27, 2016 was approximately $5.2 million and $5.0 million , 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 $0.6 million during the next 12 months due to lapsing of statutes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Operating lease commitments. As of August 27, 2016 , the Company was obligated under non-cancelable operating leases for buildings and equipment. Certain leases provide for increased rental payments based upon increases in real estate taxes or operating costs. Future minimum rental payments under non-cancelable operating leases are: (In thousands) Remainder of Fiscal 2017 Fiscal 2018 Fiscal 2019 Fiscal 2020 Fiscal 2021 Thereafter Total Total minimum payments $ 4,904 $ 8,572 $ 7,869 $ 6,484 $ 3,993 $ 4,984 $ 36,806 Bond commitments. In the ordinary course of business, predominantly in our Architectural Services segment, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At August 27, 2016 , $125.4 million of our backlog was bonded by performance bonds with a face value of $322.9 million . Performance bonds do not have stated expiration dates, as we are released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our current portfolio of businesses. Warranties. We accrue for warranty and claim costs as a percentage of sales based on historical trends and for specific sales credits as they become known and estimable. Actual warranty and 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, shifts in product mix and any significant changes in sales volume. A warranty rollforward is provided as follows: Six Months Ended (In thousands) August 27, 2016 August 29, 2015 Balance at beginning of period $ 16,340 $ 11,275 Additional accruals 2,577 3,205 Claims paid (3,014 ) (2,266 ) Balance at end of period $ 15,903 $ 12,214 Letters of credit. At August 27, 2016 , we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The total value of letters of credit under which we were obligated as of August 27, 2016 was approximately $23.5 million , all of which have been issued under our committed revolving credit facility. Availability under this $125.0 million credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility. Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $161.8 million as of August 27, 2016 . New Markets Tax Credit transaction. In June 2016, we entered into a transaction with a subsidiary of Wells Fargo (WF) under a qualified New Markets Tax Credit (NMTC) program related to an investment in plant and equipment within our Architectural Glass segment (the Project). The NMTC transaction is subject to 100 percent tax credit recapture for a period of seven years. Therefore, proceeds received in exchange for the transfer of the tax credits will be recognized as earnings in fiscal 2024, if the expected tax benefits are delivered without risk of recapture to WF and our performance obligation is relieved. In exchange for substantially all of the benefits derived from the tax credits, WF contributed $6.0 million to the Project, which is included in other non-current liabilities on our consolidated balance sheets. Direct and incremental costs incurred in structuring the arrangement have been deferred and will be recognized in proportion to the recognition of the related profits. These costs amounted to $0.9 million and are included in other non-current assets on our consolidated balance sheets. Variable-interest entities have been created as a result of the transaction structure, which have been included within our consolidated financial statements as WF does not have a material interest in the underlying economics of the Project. Litigation. We are a party to various legal proceedings incidental to our normal operating activities. In particular, like others in the construction supply and services industry, our businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. We are also subject to litigation arising out of general liability, employment practices, workers' compensation and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on our results of operations, cash flows or financial condition.
