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 28, 2015 . 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 six -month period ended August 29, 2015 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 29, 2015 , we have evaluated subsequent events for potential recognition and disclosure through the date of this filing and determined there were no items to recognize or disclose.

Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued a standard on revenue from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principle of the revenue model is that 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. In July 2015, the effective date for implementation was extended to annual reporting periods beginning after December 15, 2017, our fiscal 2019. We are currently evaluating the impact that this standard will have on our financial statements. We do not expect that any other recently issued accounting pronouncements will have a significant effect on our financial statements.

In the current year, the Company invested in a mutual fund holding government short-term securities and commercial paper as a means of deploying excess cash generated from operations while preserving liquidity. The Company’s wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism), holds our municipal bonds. Prism insures a portion of the Company’s workers’ compensation, general liability 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. The Company tests for other-than-temporary losses on a quarterly basis and considers the unrealized losses indicated above to be temporary in nature. The Company intends to hold the investments until it can recover the full principal amount, and has the ability to do so based on other sources of liquidity. The Company expects such recoveries to occur prior to the contractual maturities. The amortized cost and estimated fair values of municipal bonds and commercial paper at August 29, 2015 , 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 29, 2015 consists of $20.4 million of industrial revenue bonds, $0.9 million on a Canadian revolving credit facility and $0.2 million of other debt. The industrial revenue bonds mature in fiscal years 2021 through 2043, borrowings under our U.S. revolving facility mature in fiscal 2020 and the other debt matures in fiscal years 2016 through 2021. The fair value of the industrial revenue bonds and revolving credit facility borrowings approximates carrying value at August 29, 2015 , due to the variable interest rates on these instruments. The bonds are classified as Level 2 within the fair value hierarchy described in Note 7. The Company maintains a $125.0 million committed revolving credit facility that expires in December 2019 . No borrowings were outstanding under the facility as of August 29, 2015 or February 28, 2015 . This credit facility requires the Company to maintain a debt-to-EBITDA ratio of not more than 3.00 . This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. The Company’s ratio was 0.19 at August 29, 2015 . The credit facility also requires the Company to maintain a minimum level of net worth, as defined in the credit facility, based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit facility at August 29, 2015 was $338.3 million , whereas the Company’s net worth as defined in the credit facility was $401.6 million . If the Company is not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At August 29, 2015 , the Company was in compliance with the financial covenants of the credit facility. We also maintain a Canadian dollar $4.0 million revolving demand facility available to our Canadian operation. 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. The Company classifies any outstanding balances under this demand facility as long-term debt, as outstanding amounts can be refinanced through our committed revolving credit facility. As of August 29, 2015 , $0.9 million was outstanding under this facility. No borrowings were outstanding under this facility as of February 28, 2015 . Interest payments were $0.3 million for each of the six months ended August 29, 2015 and August 30, 2014 , and primarily relate to fees associated with our revolving credit facility.

The Company records the impact of penalties and interest related to unrecognized tax benefits in income tax expense, which is consistent with past practices. 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.

In the ordinary course of business, predominantly in the Company’s Architectural Services business, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance by the Company. At August 29, 2015 , $123.7 million of the Company’s backlog was bonded by performance bonds with a face value of $322.1 million . Performance bonds do not have stated expiration dates, as the Company is released from the bonds upon completion of the contract. The Company has never been required to make any payments related to these performance bonds with respect to any of its current portfolio of businesses. Warranties. The Company accrues 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. The Company’s warranty and claim accruals are detailed below.

The Company has purchase obligations for raw material commitments and capital expenditures. As of August 29, 2015 , these obligations totaled $134.8 million . 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’s construction supply and services businesses are 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 employment practices, workers compensation, general liability 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 the results of operations, cash flows or financial condition of the Company.
