Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Quanex Building Products Corporation is a component supplier to original equipment manufacturers (OEMs) in the building products industry. These components can be categorized as window and door (fenestration) components and kitchen and bath cabinet components. Examples of fenestration components include: (1) energy-efficient flexible insulating glass spacers, (2) extruded vinyl profiles, (3) window and door screens, and (4) precision-formed metal and wood products. We also manufacture cabinet doors and other components for OEMs in the kitchen and bathroom cabinet industry. In addition, we provide certain other non-fenestration components and products, which include solar panel sealants, trim moldings, vinyl decking, fencing, water retention barriers, and conservatory roof components. We have organized our business into three reportable business segments. For additional discussion of our reportable business segments, see Note 14, "Segment Information." We use low-cost, short lead-time production processes and engineering expertise to provide our customers with specialized products for their specific window, door, and cabinet applications. We believe these capabilities provide us with unique competitive advantages. We serve a primary customer base in North America and the United Kingdom, and also serve customers in international markets through our operating plants in the United Kingdom and Germany, as well as through sales and marketing efforts in other countries. Unless the context indicates otherwise, references to "Quanex", the "Company", "we", "us" and "our" refer to the consolidated business operations of Quanex Building Products Corporation and its subsidiaries. The accompanying interim condensed consolidated financial statements include the accounts of Quanex Building Products Corporation. All intercompany accounts and transactions have been eliminated in consolidation. These financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet as of October 31, 2017 was derived from audited financial information, but does not include all disclosures required by U.S. GAAP. The accompanying financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2017 . In our opinion, the accompanying financial statements contain all adjustments (which consist of normal recurring adjustments, except as disclosed herein) necessary to fairly present our financial position, results of operations and cash flows for the interim periods. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year or for any future periods. In preparing financial statements, we make informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. We review our estimates on an on-going basis, including those related to impairment of long lived assets and goodwill, contingencies and income taxes. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates. Restructuring We accrue one-time severance costs pursuant to an approved plan of restructuring at the communication date, when affected employees have been notified of the potential severance and sufficient information has been provided for the employee to calculate severance benefits, in the event the employee is involuntarily terminated. In addition, we accrue costs associated with the termination of contractual commitments including operating leases at the time the lease is terminated pursuant to the lease provisions or in accordance with another agreement with the landlord. Otherwise, we continue to recognize operating lease expense through the cease-use date. After the cease-use date, we determine if our operating lease payments are at market. We assume sublet of the facility at the market rate. To the extent our lease obligations exceed the fair value rentals, we discount to arrive at the present value and record a liability. If the facility is not sublet, we expense the amount of the rental in the current period. For other costs directly related to the restructuring effort, such as equipment moving costs, we expense in the period incurred. We closed a kitchen and bathroom cabinet door business in Mexico in October 2016 and another plant in Lansing, Kansas in September 2017. We closed two United States vinyl operations plants in November 2016 and January 2017. Pursuant to these restructuring efforts, we expensed $0.2 million and $0.6 million during the three and six months ended April 30, 2018 respectively, and $1.1 million and $2.2 million , respectively, for the comparable prior year periods. Our facility lease obligations were deemed to be at fair market value and we have not yet negotiated exit from our remaining lease obligations at two of these facilities. We expect to continue to incur costs related to these operating leases and other costs associated with these restructuring efforts during fiscal 2018. In 2017, we evaluated the remaining depreciable lives of property, plant and equipment that will be abandoned or otherwise disposed as of the plant closures and recorded a change in estimate associated with the remaining useful lives of these assets. We recorded accelerated depreciation of $1.4 million and $3.0 million related to this change in estimate for the three and six months ended April 30, 2017, respectively. In addition, we evaluated the remaining service lives of intangible assets with defined lives associated with our United States vinyl extrusion business and recorded a change in estimate associated with the remaining useful lives of a customer relationship intangible and a utility process intangible asset which resulted in an increase in amortization expense of $0.3 million and $1.3 million for the three and six months ended April 30, 2017 , respectively. We do not expect to incur incremental depreciation and amortization expense in fiscal 2018 associated with these restructuring efforts. Acquisitions As more fully described in our Annual Report on Form 10-K for the year ended October 31, 2017, on November 7, 2016, we paid $8.5 million pursuant to an earn-out provision for the acquisition of HLP. We have included this earn-out payment under the caption "Acquisitions, net of cash acquired" in the accompanying cash flow statement for the six months ended April 30, 2017 . Related Parties We are party to operating leases associated with HLP for which a former owner, who is now our employee, has an ownership interest. These leases include our primary operating facilities, a finished goods warehouse, a mixing plant, and a manufacturing facility. The lease for the manufacturing facility which has a 20 -year term began in 2007, the lease for the manufacturing facility which has a 15 -year term began in 2012, the lease for the mixing plant has a 13.5 -year term which began in 2013, and the lease for the warehouse has a 20 -year life which began in 2017. We have recorded rent expense pursuant to these agreements of approximately $0.6 million and $1.2 million , for the three and six months ended April 30, 2018 , respectively and $0.3 million and $0.6 million , respectively, for the comparable prior year periods. Commitments under these lease arrangements are included in our operating lease commitments as disclosed in our Annual Report on Form 10-K for the year ended October 31, 2017.

Our inventories at April 30, 2018 and October 31, 2017 were valued using the following costing methods: April 30, October 31, (In thousands) LIFO $ 5,522 $ 4,444 FIFO 87,406 83,085 Total $ 92,928 $ 87,529 During interim periods, we estimate a LIFO reserve based on our expectations of year-end inventory levels and costs. If our calculations indicate that an adjustment at year-end will be required, we may record a proportionate share of this amount during the period. At year-end, we calculate the actual LIFO reserve and record an adjustment for the difference between the annual calculation and any estimates recognized during the interim periods. Because the interim projections are subject to many factors beyond our control, the results could differ significantly from the year-end LIFO calculation. We did not record an interim LIFO reserve adjustment for the six months ended April 30, 2018 and 2017 . For inventories valued under the LIFO method, replacement cost exceeded the LIFO value by approximately $1.1 million at April 30, 2018 and October 31, 2017 .

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill The change in the carrying amount of goodwill for the six months ended April 30, 2018 was as follows: Six Months Ended April 30, 2018 (In thousands) Beginning balance as of November 1, 2017 $ 222,194 Foreign currency translation adjustment 2,534 Balance as of the end of the period $ 224,728 At our last annual test date, August 31, 2017, we evaluated the recoverability of goodwill at each of our five reportable units with goodwill balances and determined that our goodwill was not impaired. For the reporting unit included in our NA Cabinet Components operating segment, we performed the first step of the goodwill impairment test at March 31, 2018, as our annual long-range planning effort produced lower forecasted results compared to the prior year’s process, a potential indicator of impairment. We determined the fair value of this reportable unit exceeded its carrying value by approximately 4.5% as of March 31, 2018, a reduction from the 5.2% at our August 31, 2017 testing date. Should our actual results for our NA Cabinet Components operating segment be lower than expected in the future, the corresponding goodwill could become impaired and the impairment could be material. The goodwill impairment testing process is more fully described in our Annual Report on Form 10-K for the year ended October 31, 2017. For a summary of the change in the carrying amount of goodwill by segment, see Note 13, "Segment Information", included herewith.

See additional disclosure at Note 1, "Nature of Operations, Basis of Presentation and Significant Accounting Policies - Restructuring." During the six months ended April 30, 2018 , we retired identifiable intangible assets of $0.3 million related to patents and other technology. We had aggregate amortization expense related to intangible assets for the three and six months ended April 30, 2018 of $4.1 million and $8.2 million , respectively, and $4.4 million and $9.9 million , respectively, for the comparable prior year periods. Estimated remaining amortization expense, assuming current intangible balances and no new acquisitions, for each of the fiscal years ending October 31, is as follows (in thousands): Estimated Amortization Expense 2018 (remaining six months) $ 8,055 2019 15,499 2020 14,442 2021 12,721 2022 12,096 Thereafter 70,380 Total $ 133,193

The Credit Agreement has a five-year term, maturing on July 29, 2021, and requires interest payments calculated, at our election and depending upon our Consolidated Leverage Ratio, at either a Base Rate plus an applicable margin or the LIBOR Rate plus an applicable margin. At the time of the initial borrowing, the applicable rate was LIBOR + 2.00% . In addition, we are subject to commitment fees for the unused portion of the Credit Agreement. The applicable margin and commitment fees are outlined in the following table: Pricing Level Consolidated Leverage Ratio Commitment Fee LIBOR Rate Loans Base Rate Loans I Less than or equal to 1.50 to 1.00 0.200% 1.50% 0.50% II Greater than 1.50 to 1.00, but less than or equal to 2.25 to 1.00 0.225% 1.75% 0.75% III Greater than 2.25 to 1.00, but less than or equal to 3.00 to 1.00 0.250% 2.00% 1.00% IV Greater than 3.00 to 1.00 0.300% 2.25% 1.25% In the event of default, outstanding borrowings would accrue interest at the Default Rate, as defined, whereby the obligations will bear interest at a per annum rate equal to 2% above the total per annum rate otherwise applicable. The term loan portion of the Credit Agreement requires quarterly principal payments on the last business day of each fiscal quarter in accordance with a stated repayment schedule. Required aggregate principal repayments total $15.0 million for the succeeding twelve-month period, and are included in the accompanying condensed consolidated balance sheet under the caption “Current Maturities of Long-term Debt.” No stated principal payments are required under the revolving credit portion of the Credit Agreement, except upon maturity. Mandatory prepayments of "excess cash flow" as defined in the agreement are required until we achieve a Consolidated Leverage Ratio less than 2.25 to 1.00, after which, prepayments of “excess cash flow” as defined in the agreement are no longer required. The Credit Agreement contains a: (1) Consolidated Fixed Charge Coverage Ratio requirement whereby we must not permit the Consolidated Fixed Charge Coverage Ratio, as defined, to be less than 1.10 to 1.00, and (2) Consolidated Leverage Ratio requirement, as summarized by period in the following table: Period Maximum Ratio January 31, 2017 through January 30, 2018 3.25 to 1.00 January 31, 2018 and thereafter 3.00 to 1.00 In addition to maintaining these financial covenants, the Credit Agreement also limits our ability to enter into certain business transactions, such as to incur indebtedness or liens, to acquire businesses or dispose of material assets, make restricted payments, pay dividends (limited to $10.0 million per year) and other transactions as further defined in the Credit Agreement. Substantially all of our domestic assets, with the exception of real property, are utilized as collateral for the Credit Agreement. As of April 30, 2018 , we had $210.3 million of borrowings outstanding under the Credit Agreement (reduced by unamortized debt issuance costs of $1.8 million ), $5.3 million of outstanding letters of credit and $18.6 million outstanding primarily under capital leases. We had $215.7 million available for use under the Credit Agreement at April 30, 2018 . Outstanding borrowings under the Credit Agreement accrue interest at 3.90% per annum. Our weighted average borrowing rate for borrowings outstanding during the six months ended April 30, 2018 and 2017 was 3.55% and 2.76% , respectively. We were in compliance with our debt covenants as of April 30, 2018 . Other Debt Instruments Historically, we have maintained certain capital lease obligations related to equipment purchases. On February 20, 2017, we entered into a capital lease for warehouse space at HLP with a related-party company that is owned by our employee, the former owner of HLP. This new warehouse was anticipated at the time of the HLP acquisition in June 2015, and the lease was negotiated at arms-length. The lease accrues interest at 3.57% per annum, and extends for a twenty-year period through the year 2036. We recorded the leased asset at inception at fair value of $16.6 million and recorded a corresponding liability for our obligation under this lease. We are recognizing interest expense using the effective interest method over the term. Our cash commitments under this lease are £0.9 million per year for an aggregate of £17.8 million (or approximately $25.5 million ). The cost and accumulated depreciation of property, plant and equipment under all outstanding capital leases at April 30, 2018 was $23.4 million and $2.7 million , respectively, including $17.6 million and $0.9 million , respectively, related to the HLP warehouse lease. Our total obligations under capital leases and other total $18.6 million at April 30, 2018 , of which $1.7 million is classified in the current portion of long-term debt and $16.9 million is classified as long-term debt on the accompanying unaudited condensed consolidated balance sheet. These obligations accrue interest at an average rate of 3.6% , and extend through the year 2036 .

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans Pension Plan Our non-contributory, single employer defined benefit pension plan covers a majority of our employees in the United States excluding employees of recent acquisitions. Employees of acquired companies may be covered after a transitional period. The net periodic pension cost for this plan for the three and six months ended April 30, 2018 and 2017 was as follows: Three Months Ended Six Months Ended April 30, April 30, 2018 2017 2018 2017 (In thousands) Service cost $ 1,023 $ 971 $ 1,972 $ 1,897 Interest cost 354 216 568 428 Expected return on plan assets (621 ) (474 ) (1,087 ) (931 ) Amortization of net (gain) loss (102 ) 144 42 286 Net periodic benefit cost $ 654 $ 857 $ 1,495 $ 1,680 During 2017, we contributed $3.6 million to fund our plan, and we expect to make a contribution to our plan in September 2018 of approximately $3.6 million . Other Plans We also have a supplemental benefit plan covering certain executive officers and a non-qualified deferred compensation plan covering members of the Board of Directors and certain key employees. As of April 30, 2018 and October 31, 2017 , our liability under the supplemental benefit plan was approximately $3.7 million and $3.4 million , respectively. The liability associated with the deferred compensation plan was approximately $3.7 million and $4.0 million as of April 30, 2018 and October 31, 2017, respectively. We record the current portion of liabilities associated with these plans under the caption "Accrued Liabilities," and the long-term portion under the caption "Other Liabilities" in the accompanying condensed consolidated balance sheets.

Warranty Obligations	Warranty Obligations We accrue warranty obligations as we recognize revenue associated with certain products. We make provisions for our warranty obligations based upon historical experience of costs incurred for such obligations adjusted, as necessary, for current conditions and factors. There are significant uncertainties and judgments involved in estimating our warranty obligations, including changing product designs, differences in customer installation processes and future claims experience which may vary from historical claims experience. Therefore, the ultimate amount we incur as warranty costs in the near and long-term may not be consistent with our current estimate. A reconciliation of the activity related to our accrued warranty, including both the current and long-term portions (reported in accrued liabilities and other liabilities, respectively, on the accompanying condensed consolidated balance sheet) follows: Six Months Ended April 30, 2018 (In thousands) Beginning balance as of November 1, 2017 $ 323 Provision for warranty expense 8 Warranty costs paid (15 ) Total accrued warranty as of the end of the period $ 316 Less: Current portion of accrued warranty 152 Long-term portion of accrued warranty $ 164

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes To determine our income tax expense or benefit for interim periods, consistent with accounting standards, we apply the estimated annual effective income tax rate to year-to-date results. Our estimated annual effective tax rates for the six months ended April 30, 2018 and 2017 were 24.0% and 30.1% , respectively, excluding discrete items. The change in the annual rate was due largely to the effect of the Tax Cuts and Jobs Act (the Act) which was signed into law on December 22, 2017. The Act reduced our federal income tax rate from 35.0% to 23.3% for the fiscal year ending October 31, 2018. Discrete items contributing to the income tax benefit for the six months ended April 30, 2018 included $7.7 million for the re-measurement of our deferred income tax assets and liabilities due to the decrease in the federal corporate income tax rate and a benefit of $0.3 million for the true up of our accruals and related deferred taxes from prior year filings and settled tax audits, partially offset by a tax expense of $1.2 million for the one-time mandatory transition tax on deemed repatriation of previously tax-deferred and unremitted foreign earnings. The following table reconciles our effective income tax benefit rate to the federal statutory rate of 23.3% and 35.0% for the six months ended April 30, 2018 and 2017 , respectively: Six months ended April 30, 2018 2017 United States tax at statutory rate 23.3 % 35.0 % State and local income tax 2.7 1.5 Non-United States income tax (1.0 ) (7.1 ) Other permanent differences (1.0 ) 0.7 Deferred rate impact of enactment of tax reform (266.5 ) — Tax impact of stock based compensation (1.4 ) — Impact of deemed repatriation 42.0 — Return to actual adjustments (9.6 ) — Effective tax benefit rate (211.5 )% 30.1 % The United States statutory rate of 23.3% reflects the period November 1, 2017 to December 31, 2017 at the previous 35.0% rate and the period January 1, 2018 to October 31, 2018 at the new 21.0% rate. Given the significance of the Act, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period”. During the measurement period, impacts of the Act are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared or analyzed. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Act. As of April 30, 2018 , we have not completed the accounting for the tax effects of the Act. However, we have made an initial assessment of the Act and recorded a discrete benefit of $6.5 million during the six-month period ended April 30, 2018 . We believe that our assessment of the re-measurement of our deferred income tax assets and liabilities to be complete, while we consider our tax expense related to the one-time mandatory transition tax on deemed repatriation of previously tax-deferred and unremitted foreign earnings and our tax benefit of stock based compensation to be provisional. At this time, our estimate does not reflect changes in current interpretations of compensation deduction limitations, effects of any state tax law changes and uncertainties regarding interpretations that may arise as a result of federal tax reform. Any additional impact of the enactment of the Act will be recorded as they are identified during the one-year measurement period provided for in SAB 118. In light of the Act, we repatriated $2.5 million of excess cash from our insulating glass spacer division in the United Kingdom. This was repatriation of excess cash that was a portion of the one-time mandatory transition tax discussed above. We will continue to evaluate our foreign cash position and may repatriate additional foreign earnings in the future. With the exception of the one-time mandatory transition tax on deemed repatriation of previously tax-deferred and unremitted foreign earnings, we do not anticipate any material tax impact from any potential repatriation of previously unremitted foreign earnings. As of April 30, 2018 , our liability for uncertain tax positions (UTP) of $0.6 million relates to certain state tax items regarding the interpretation of tax laws and regulations. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. The final outcome of the future tax consequences of legal proceedings, if any, as well as the outcome of competent authority proceedings, changes in regulatory tax laws, or interpretation of those tax laws could impact our financial statements. We are subject to the effect of these matters occurring in various jurisdictions. The disallowance of the UTP would not materially affect the annual effective tax rate. We do not believe any of the UTP at April 30, 2018 will be recognized within the next twelve months. We evaluate the likelihood of realization of our deferred tax assets by considering both positive and negative evidence. We believe there is no need for a valuation allowance of the federal net operating losses. We will continue to evaluate our position throughout the year. We maintain a valuation allowance for certain state net operating losses which totaled $1.3 million at April 30, 2018 .

Contingencies	Contingencies Remediation and Environmental Compliance Costs Under applicable state and federal laws, we may be responsible for, among other things, all or part of the costs required to remove or remediate wastes or hazardous substances at locations we, or our predecessors, have owned or operated. From time to time, we also have been alleged to be liable for all or part of the costs incurred to clean up third-party sites where there might have been an alleged improper disposal of hazardous substances. At present, we are not involved in any such matters. From time to time, we incur routine expenses and capital expenditures associated with compliance with existing environmental regulations, including control of air emissions and water discharges, and plant decommissioning costs. We have not incurred any material expenses or capital expenditures related to environmental matters during the past three fiscal years, and do not expect to incur a material amount of such costs in fiscal 2018. While we will continue to have future expenditures related to environmental matters, any such amounts are impossible to reasonably estimate at this time. Based upon our experience to date, we do not believe that our compliance with environmental requirements will have a material adverse effect on our operations, financial condition or cash flows. Spacer Migration We were notified by certain customers through our German operation that the vapor barrier employed on certain spacer products manufactured prior to March 2014 may permit spacer migration in certain extreme circumstances. This product does not have a specific customer warranty, but we have received claims from customers related to this issue, which we continue to investigate. The balance of the accrual for this matter was $1.3 million and $1.6 million at October 31, 2017 and April 30, 2018 . During the six months ended April 30, 2018 , we incurred additional claims of $1.0 million , which were offset by payments of $0.7 million . We cannot estimate any future liability with regard to unasserted claims. We evaluate this reserve at each balance sheet date. We investigate any claims, but we are not obligated to honor any future claims. Litigation From time to time, we, along with our subsidiaries, are involved in various litigation matters arising in the ordinary course of our business, including those arising from or related to contractual matters, commercial disputes, intellectual property, personal injury, environmental matters, product performance or warranties, product liability, insurance coverage and personnel and employment disputes. We regularly review with legal counsel the status of all ongoing proceedings, and we maintain insurance against these risks to the extent deemed prudent by our management and to the extent such insurance is available. However, there is no assurance that we will prevail in these matters or that our insurers will accept full coverage of these matters, and we could, in the future, incur judgments, enter into settlements of claims, or revise our expectations regarding the outcome or insurability of matters we face, which could materially impact our results of operations. We have been and are currently party to multiple claims, some of which are in litigation, relating to alleged defects in a commercial sealant product that was manufactured and sold during the 2000's. During the six months ended April 30, 2018 , our insurance carrier reimbursed fees and expenses originally incurred as part of our defense of these various commercial sealant claims totaling $0.5 million . While we believe that our product was not defective and that we would prevail in these commercial sealant product claims if taken to trial, the timing, ultimate resolution and potential impact of these claims is not currently determinable. Nevertheless, after taking into account all currently available information, including our defenses, the advice of our counsel, and the extent and currently-expected availability of our existing insurance coverage, we believe that the eventual outcome of these commercial sealant claims will not have a material adverse effect on our overall financial condition, results of operations or cash flows, and we have not recorded any accrual with regard to these claims.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Our derivative activities are subject to the management, direction, and control of the Chief Financial Officer and Chief Executive Officer. Certain transactions in excess of specified levels require further approval from the Board of Directors. The nature of our business activities requires the management of various financial and market risks, including those related to changes in foreign currency exchange rates. We have historically used foreign currency forwards and options to mitigate or eliminate certain of those risks at our subsidiaries. We use foreign currency contracts to offset fluctuations in the value of accounts receivable and accounts payable balances that are denominated in currencies other than the United States dollar, including the Euro, British Pound and Canadian Dollar. Currently, we do not enter into derivative transactions for speculative or trading purposes. We are exposed to credit loss in the event of nonperformance by the counterparties to our derivative transactions. We attempt to mitigate this risk by monitoring the creditworthiness of our counterparties and limiting our exposure to individual counterparties. In addition, we have established master netting agreements in certain cases to facilitate the settlement of gains and losses on specific derivative contracts. We have not designated any of our derivative contracts as hedges for accounting purposes in accordance with the provisions under the Accounting Standards Codification Topic 815 "Derivatives and Hedging " (ASC 815). Therefore, changes in the fair value of these contracts and the realized gains and losses are recorded in the unaudited condensed consolidated statements of income (loss) for the three and six months ended April 30, 2018 and 2017 as follows (in thousands): Three Months Ended Six Months Ended April 30, April 30, Location of gains (losses): 2018 2017 2018 2017 Other, net Foreign currency derivatives 26 (34 ) (29 ) 110 We have chosen not to offset any of our derivative instruments in accordance with the provisions of ASC 815. Therefore, the assets and liabilities are presented on a gross basis on the accompanying condensed consolidated balance sheets. Less than $0.1 million of fair value related to foreign currency derivatives was included in prepaid and other current assets as of April 30, 2018 and October 31, 2017. Less than $0.1 million of fair value related to foreign currency derivatives was included in accrued liabilities as of October 31, 2017 .

Fair Value Measurement of Asset

Fair Value Measurement of Assets and Liabilities	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement of Assets and Liabilities	Fair Value Measurement of Assets and Liabilities 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 at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market data developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to Level 1 and the lowest priority to Level 3. The three levels of the fair value hierarchy are described below: • 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 within Level 1 that are observable for the asset or liability either directly or indirectly including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates) and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 - Inputs that are both significant to the fair value measurement and unobservable. As of April 30, 2018 and October 31, 2017 , foreign currency derivatives were the only instruments being measured on a recurring basis. Less than $0.1 million of foreign currency derivatives were included in total assets as of April 30, 2018 and less than $0.1 million of foreign currency derivatives were included in total assets and total liabilities as of October 31, 2017 . All of our derivative contracts are valued using quoted market prices from brokers or exchanges and are classified within Level 2 of the fair value hierarchy. We have recorded land totaling approximately $2.4 million at fair value on a non-recurring basis which is classified as a Level 3 measurement as of April 30, 2018 and October 31, 2017 . The fair value was based on broker opinions received during the fourth fiscal quarter of the year ended October 31, 2017. Carrying amounts reported on the balance sheet for cash, cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Our outstanding debt is variable rate debt that re-prices frequently, thereby limiting our exposure to significant change in interest rate risk. As a result, the fair value of our debt instruments approximates carrying value at April 30, 2018 , and October 31, 2017 (Level 3 measurement).

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation We have established and maintain an Omnibus Incentive Plan (2008 Plan) that provides for the granting of restricted stock awards, stock options, restricted stock units, performance share awards, performance restricted stock units, and other stock-based and cash-based awards. The 2008 Plan is administered by the Compensation and Management Development Committee of the Board of Directors. The aggregate number of shares of common stock authorized for grant under the 2008 Plan is 7,650,000 as approved by shareholders. Any officer, key employee and/or non-employee director is eligible for awards under the 2008 Plan. We grant restricted stock units to non-employee directors on the first business day of each fiscal year. As approved by the Compensation & Management Development Committee of our Board of Directors annually, we grant a mix of stock options, restricted stock awards, performance shares and/or performance restricted stock units to officers, management and key employees. Occasionally, we may make additional grants to key employees at other times during the year. Restricted Stock Awards Restricted stock awards are granted to key employees and officers annually, and typically cliff vest over a three year period with service and continued employment as the only vesting criteria. The recipient of the restricted stock award is entitled to all of the rights of a shareholder, except that the award is nontransferable during the vesting period. The fair value of the restricted stock award is established on the grant date and then expensed over the vesting period resulting in an increase in additional paid-in-capital. Shares are generally issued from treasury stock at the time of grant. A summary of non-vested restricted stock awards activity during the six months ended April 30, 2018 is presented below: Restricted Stock Awards Weighted Average Non-vested at October 31, 2017 284,300 $ 19.66 Granted 73,400 20.70 Cancelled (14,400 ) 19.57 Vested (61,800 ) 20.28 Non-vested at April 30, 2018 281,500 $ 19.80 The total weighted average grant-date fair value of restricted stock awards that vested during each of the six month periods ended April 30, 2018 and 2017 was $1.3 million and $1.2 million , respectively. As of April 30, 2018 , total unrecognized compensation cost related to unamortized restricted stock awards was $2.5 million . We expect to recognize this expense over the remaining weighted average vesting period of 2.0 years . Stock Options Historically, stock options have been awarded to key employees, officers and non-employee directors. Effective May 2015, the director compensation structure was revised to eliminate the annual grant of stock options to non-employee directors. Employee stock options typically vest ratably over a three -year period with service and continued employment as the vesting conditions. Our stock options may be exercised up to a maximum of ten years from the date of grant. The fair value of the stock options is determined on the grant date and expensed over the vesting period resulting in an increase in additional paid-in-capital. For employees who are nearing retirement-eligibility, we recognize stock option expense ratably over the shorter of the vesting period or the period from the grant-date to the retirement-eligibility date. During December 2017, the Compensation & Management Committee of the Board of Directors approved a change to the long-term incentive award program eliminating the grant of stock options and replacing this award with a grant of performance restricted stock units as further described below. We use a Black-Scholes pricing model to estimate the fair value of stock options. A description of the methodology for the valuation assumptions was disclosed in our Annual Report on Form 10-K for the fiscal year ended October 31, 2017 . The following table provides a summary of assumptions used to estimate the fair value of our stock options issued during the six months ended April 30, 2017 . Six Months Ended April 30, 2017 Weighted-average expected volatility 34.7% Weighted-average expected term (in years) 5.7 Risk-free interest rate 2.0% Expected dividend yield over expected term 1.0% Weighted average grant date fair value $6.25 The following table summarizes our stock option activity for the six months ended April 30, 2018 : Stock Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (000s) Outstanding at October 31, 2017 2,152,758 $ 17.44 Granted — — Exercised (199,097 ) 12.88 Forfeited/Expired (19,885 ) 19.30 Outstanding at April 30, 2018 1,933,776 $ 17.90 4.8 $ 1,556 Vested or expected to vest at April 30, 2018 1,933,776 $ 17.90 4.8 $ 1,556 Exercisable at April 30, 2018 1,668,799 $ 17.66 4.3 $ 1,556 Intrinsic value is the amount by which the market price of the common stock on the date of exercise exceeds the exercise price of the stock option. The total intrinsic value of stock options exercised during the six months ended April 30, 2018 and 2017 was $1.9 million and $0.1 million . The weighted-average grant date fair value of stock options that vested during the six months ended April 30, 2018 and 2017 was $1.5 million and $1.8 million , respectively. As of April 30, 2018 , total unrecognized compensation cost related to stock options was $0.5 million . We expect to recognize this expense over the remaining weighted average vesting period of 1.3 years . Restricted Stock Units Restricted stock units may be awarded to key employees and officers from time to time, and annually to non-employee directors. The non-employee director restricted stock units vest immediately but are payable only upon the director's cessation of service unless an election is made by the non-employee director to settle and pay the award on an earlier specified date. Restricted stock units awarded to employees and officers typically cliff vest after a three -year period with service and continued employment as the vesting conditions. Restricted stock units are not considered outstanding shares and do not have voting rights, although the holder does receive a cash payment equivalent to the dividend paid, on a one-for-one basis, on our outstanding common shares. Once the criteria is met, each restricted stock unit is payable to the holder in cash based on the market value of one share of our common stock. Accordingly, we record a liability for the restricted stock units on our balance sheet and recognize any changes in the market value during each reporting period as compensation expense. As of April 30, 2018 , there were no non-vested restricted stock units. During the six month periods ended April 30, 2018 and 2017 , non-employee directors received 18,050 and 24,560 restricted stock units, respectively, at a grant date fair value of $21.85 and $15.65 , respectively, which vested immediately. During the six month periods ended April 30, 2018 and 2017 , there were no payments to settle restricted stock units. Performance Share Awards We have awarded annual grants of performance shares to key employees and officers. These awards cliff vest after a three -year period with service and performance measures (relative total shareholder return (R-TSR) and earnings per share (EPS) growth), as vesting conditions. However, the number of shares earned is variable depending on the metrics achieved, and the settlement method is 50% in cash and 50% in our common stock. To account for these awards, we have bifurcated the portion subject to a market condition (relative total shareholder return) and the portion subject to an internal performance measure (earnings per share growth). We have further bifurcated these awards based on the settlement method, as the portion expected to settle in stock (equity component) and the portion expected to settle in cash (liability component). To value the shares subject to the market condition, we utilized a Monte Carlo simulation model to arrive at a grant-date fair value. This amount will be expensed over the three-year term of the award with a credit to additional paid-in-capital. To value the shares subject to the internal performance measure, we used the value of our common stock on the date of grant as the grant-date fair value per share. This amount is being expensed over the three -year term of the award, with a credit to additional paid-in-capital, and could fluctuate depending on the number of shares ultimately expected to vest based on our assessment of the probability that the performance conditions will be achieved. For both performance conditions, the portion of the award expected to settle in cash is recorded as a liability and is being marked to market over the three -year term of the award, and can fluctuate depending on the number of shares ultimately expected to vest. Depending on the achievement of the performance conditions, 0% to 200% of the awarded performance shares may ultimately vest. The following table summarizes our performance share grants and the grant date fair value for the EPS and R-TSR performance metrics: Grant Date Fair Value Grant Date Shares Awarded EPS R-TSR Shares Forfeited December 2, 2015 158,100 $ 19.31 $ 23.72 15,400 January 25, 2016 4,300 17.46 26.65 — November 30, 2016 186,500 19.45 26.61 7,400 December 7, 2017 146,500 $ 20.70 $ 21.81 3,900 On December 3, 2017, 123,600 shares vested pursuant to the December 2014 grant, resulting in the issuance of 25,340 shares of common stock and a cash payment of $0.6 million . The November 2016 and December 2017 grants include a return on invested capital (ROIC) metric which, if achieved, could enhance the number of shares that are ultimately issued but cannot exceed the maximum (200%). Due to the uncertainty with regard to achieving this metric, no value has been assigned. In the event and at such time the metric is deemed achievable, compensation expense will begin to be recognized through the remaining vesting period. During the three and six months ended April 30, 2018 , we recorded a decrease in compensation expense of $1.0 million and $1.6 million , respectively, which reflects a decrease in the number of shares expected to vest in December 2018 associated with the December 2, 2015 performance share grant, as well as current expense for other outstanding performance share grants. During the three and six months ended April 30, 2017, we recorded compensation expense of $0.7 million and $1.7 million related to our performance share awards. Performance share awards are not considered outstanding shares and do not have voting rights, although dividends are accrued over the performance period and will be payable in cash based upon the number of performance shares ultimately earned. The performance shares are excluded from the diluted weighted-average shares used to calculate earnings per share until the performance criteria is probable to result in the issuance of contingent shares. As of April 30, 2018 , we have deemed no shares related to the December 2015 grant of performance shares as probable to vest. Performance Restricted Stock Units We awarded performance restricted share units to key employees and officers in December 2017. These awards cliff vest upon a three-year service period with the absolute total shareholder return of our common stock over this three-year term as the vesting criteria. The number of shares earned is variable depending on the metric achieved, and the settlement method is 100% in our common stock, with accrued dividends paid in cash at the time of vesting, assuming the shares had been outstanding throughout the performance period. To value the shares, we utilized a Monte Carlo simulation model to arrive at a grant-date fair value. This amount will be adjusted for forfeitures and expensed over the three-year term of the award with a credit to additional paid-in-capital. Depending on the achievement of the performance conditions, a minimum of 0% and a maximum of 150% of the awarded performance restricted stock units may vest. Specifically, the awards vest on a continuum with the following Absolute Total Shareholder Return (A-TSR) milestones: Vesting Level Vesting Criteria Percentage of Award Vested Level 1 A-TSR greater than or equal to 50% 150% Level 2 A-TSR less than 50% and greater than or equal to 20% 100% Level 3 A-TSR less than 20% and greater than or equal to -20% 50% Level 4 A-TSR less than -20% —% On December 7, 2017, we awarded 78,200 performance restricted share units with a grant date fair value of $17.76 per share. During the six months ended April 30, 2018, 2,100 of the performance restricted share units were forfeited. During the three and six months ended April 30, 2018 , we recorded compensation expense of approximately $0.1 million and $0.2 million , respectively, related to our performance share restricted units. Similar to performance shares, the performance restricted stock units are not considered outstanding shares, do not have voting rights, and are excluded from diluted weighted-average shares used to calculate earnings per share until the performance criteria is probable to result in the issuance of contingent shares. Treasury Shares We record treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Shares are generally issued from treasury stock at the time of grant of restricted stock awards, and upon the exercise of stock options and upon the vesting of performance shares and performance restricted stock units. On the subsequent issuance of treasury shares, we record proceeds in excess of cost as an increase in additional paid in capital. A deficiency of such proceeds relative to costs would be applied to reduce paid-in-capital associated with prior issuances to the extent available, with the remainder recorded as a charge to retained earnings. We recorded a charge to retained earnings of $1.0 million during the six months ended April 30, 2018 . The following table summarizes the treasury stock activity during the six months ended April 30, 2018 : Six Months Ended April 30, 2018 Beginning balance as of November 1, 2017 2,670,743 Restricted stock awards granted (73,400 ) Performance share awards vested (25,340 ) Stock options exercised (199,097 ) Balance at April 30, 2018 2,372,906

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Information We present three reportable business segments in accordance with Topic 280-10-50, "Segment Reporting" (ASC 280): (1) North American Engineered Components segment (“NA Engineered Components”), comprising four operating segments primarily focused on the fenestration market in North America including vinyl profiles, insulating glass (IG) spacers, screens & other fenestration components; (2) European Engineered Components segment (“EU Engineered Components”), comprising our United Kingdom-based vinyl extrusion business, manufacturing vinyl profiles & conservatories, and the European insulating glass business manufacturing IG spacers; and (3) North American Cabinet Components segment (“NA Cabinet Components”), comprising solely the North American cabinet door and components business acquired in November 2015. We maintain an Unallocated Corporate & Other grouping which includes LIFO inventory adjustments, corporate office charges, and inter-segment eliminations, less an allocation of a portion of the general and administrative costs associated with the corporate office which have been allocated to the reportable business segments, based upon a relative measure of profitability, in order to more accurately reflect each reportable business segment's administrative cost. Certain costs are not allocated to the reportable operating segments, but remain in Unallocated Corporate & Other, including transaction expenses, stock-based compensation, long-term incentive awards based on the performance of our common stock and other factors, certain severance and legal costs not deemed to be allocable to all segments, depreciation of corporate assets, interest expense, other, net, income taxes and inter-segment eliminations. The accounting policies of our operating segments are the same as those used to prepare the accompanying condensed consolidated financial statements. Corporate general and administrative expense allocated during the three and six month periods ended April 30, 2018 were $4.9 million and $10.0 million , respectively, and $4.2 million and $8.5 million , respectively, for the prior year comparable periods. ASC 280 permits aggregation of operating segments based on factors including, but not limited to: (1) similar nature of products serving the building products industry, primarily the fenestration business; (2) similar production processes, although there are some differences in the amount of automation amongst operating plants; (3) similar types or classes of customers, namely the primary OEMs; (4) similar distribution methods for product delivery, although the extent of the use of third-party distributors will vary amongst the businesses; (5) similar regulatory environment; and (6) converging long-term economic similarities. Segment information for the three and six months ended April 30, 2018 and 2017 , and total assets as of April 30, 2018 and October 31, 2017 are summarized in the following table (in thousands): NA Eng.

Earnings Per Share

Earnings Per Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share We compute basic earnings (loss) per share by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include the weighted average of additional shares associated with the incremental effect of dilutive employee stock options, non-vested restricted stock as determined using the treasury stock method prescribed by U.S. GAAP and contingent shares associated with performance share awards, if dilutive. Basic and diluted earnings per share for the each of the three months ended April 30, 2018 and 2017, and for the six months ended April 30, 2018, were calculated as follows (in thousands, except per share data): Three Months Ended April 30, 2018 Net Income Weighted Average Shares Per Share Basic earnings per common share $ 4,136 34,796 $ 0.12 Effect of dilutive securities: Stock options 183 Restricted stock awards 136 Diluted earnings per common share $ 4,136 35,115 $ 0.12 Three Months Ended April 30, 2017 Net Income Weighted Average Shares Per Share Basic earnings per common share $ 1,462 34,146 $ 0.04 Effect of dilutive securities: Stock options 440 Restricted stock awards 121 Performance shares 62 Diluted earnings per common share $ 1,462 34,769 $ 0.04 Six Months Ended April 30, 2018 Net Income Weighted Average Shares Per Share Basic earnings per common share $ 9,083 34,731 $ 0.26 Effect of dilutive securities: Stock options 289 Restricted stock awards 146 Diluted earnings per common share $ 9,083 35,166 $ 0.26 Basic and diluted loss per share was $0.07 for the six months ended April 30, 2017 . The computation of diluted earnings per share excludes outstanding stock options and other common stock equivalents when their inclusion would be anti-dilutive. This is always the case when an entity incurs a net loss. During the six months ended April 30, 2017 , 426,572 shares of common stock equivalents and 121,023 shares of restricted stock were excluded from the computation of diluted earnings per share. In addition, 61,800 potentially dilutive contingent shares related to performance share awards for the six months ended April 30, 2017 were excluded. We had common stock equivalents that were potentially dilutive in future earnings per share calculations of 562,533 and 1,077,055 for the three and six months ended April 30, 2018 , respectively, and 760,712 and 1,025,007 , respectively, for the prior year comparable periods. Such dilution will be dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method.

New Accounting Guidance Adopted

New Accounting Guidance Adopted	6 Months Ended

Accounting Changes and Error Corrections [Abstract]
New Accounting Guidance Adopted	New Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This guidance prescribes a methodology to determine when revenue is recognizable and constitutes a principles-based approach to revenue recognition based on the consideration to which the entity expects to be entitled in exchange for goods or services. In addition, this guidance requires additional disclosure in the notes to the financial statements with regard to the methodology applied. This pronouncement will essentially supersede and replace existing revenue recognition rules in U.S. GAAP, including industry-specific guidance. We have reviewed our revenue streams and are currently in the process of evaluating all material contract types and costs that may be impacted by this amended guidance. We will adopt this guidance using the modified retrospective approach in the first quarter of 2019 with a cumulative adjustment to retained earnings. In July 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This amendment simplifies the subsequent measurement of inventories by replacing the lower of cost or market revaluation method with the lower of cost and net realizable value test. This guidance is applicable to all inventories measured using methods other than last-in first-out method and the retail inventory method. We adopted the provisions of ASU 2016-09 effective November 1, 2017, with no material impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This guidance prescribes the presentation of excess tax benefits or deficiencies derived from book and tax timing differences associated with stock-based compensation arrangements and certain related statement of cash flow implications. We adopted the provisions of ASU 2016-09 effective November 1, 2017, as noted below with no significant impact on our consolidated financial statements. • Excess tax benefits or deficiencies for share-based payments are to be recorded in the income tax provision, rather than as an adjustment to additional paid-in-capital. We made this change on a prospective basis; • Cash flows related to excess tax benefits or deficiencies are included in net cash provided by operating activities rather than as a financing activity. We adopted this change retrospectively, which resulted in an increase to net cash provided by operating activities and a corresponding decrease to net cash provided by financing activities of less than $0.1 million for the six months ended April 30, 2017 ; • Cash paid to taxing authorities when withholding shares from an employee’s vesting or exercise of equity-based compensation awards for tax-withholding purposes is to be classified as net cash used in financing activities rather than as an operating activity. We adopted this change retrospectively, which resulted in an increase to net cash provided by operating activities and a corresponding decrease to net cash provided by financing activities of $1.0 million for the six months ended April 30, 2017 ; • We elected to continue to withhold shares associated with stock-based compensation vesting or exercises to satisfy the minimum statutory tax withholding requirements, rather than electing to withhold at a higher rate; and • We elected to continue to estimate forfeitures rather than account for forfeitures as they occur. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This amendment requires disclosure of the accounting policy for releasing income tax effects from accumulated other comprehensive income. It also provides an option for entities to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. We elected to early adopt this ASU effective November 1, 2017. We record income tax effects related to our unrecognized pension obligations in accumulated other comprehensive income as discussed in our Annual Report on Form 10-K for the year ended October 31, 2017. We have not elected to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings.
