Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of management, the accompanying consolidated financial information reflects all adjustments necessary for a fair presentation of Albany International Corp.'s ("Albany", the "Registrant", the "Company", "we", "us", or "our") financial position, results of operations and cash flows for the interim periods presented, but does not include all disclosures required by the accounting principles generally accepted in the United States ("GAAP"). All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
Estimates	Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used in the accounting for, among others, revenue recognition, contract profitability, allowances for doubtful accounts, rebates and sales allowances, inventory allowances, financial instruments, including derivatives, pension and other postretirement benefits, stock-based compensation, goodwill and intangible assets, contingencies, income taxes, and other accruals. Our estimates are based on historical experience and on various other assumptions, which are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ from those estimates. Estimates and assumptions are reviewed periodically, and the effects of any revisions are reflected in the consolidated financial statements in the period they are determined to be necessary.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the FASB issued Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures. In March 2024, the FASB issued Accounting Standards Update No. 2024-01, "Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards" (ASU 2024-01), which clarifies how an entity determines whether profits interest or similar awards should be considered within the scope of ASC 718 as a share-based payment arrangement or under ASC 710 or other ASC topics in a manner similar to a cash bonus or profit-sharing arrangement. The guidance is effective for annual periods beginning after December 15, 2024, and interim periods beginning within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. ASU 2024-01 should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The adoption of this standard on January 1, 2025 did not have any impact on our consolidated financial statements and related disclosures. In November 2024, the FASB issued Accounting Standards Update No. 2024-03, "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" (ASU 2024-03), which requires a public business entity to disclose specific information about certain costs and expenses in the notes to the financial statements for interim and annual reporting periods. The objective of the disclosure requirements is to provide disaggregated information of the public entity's expenses to help investors better understand the entity's performance; better assess the entity's prospects for future cash flows; and compare an entity's performance over time and with that of other entities. The disaggregation of relevant expense captions presented on the face of the income statement may include but is not limited to the following natural expenses: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion, and amortization. The guidance is effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures. In March 2024, the U.S. Securities and Exchange Commission ("SEC") adopted the final rule under SEC Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors". This rule would require registrants to disclose certain climate-related information in registration statements and annual reports. In April 2024, the SEC voluntarily stayed the final rule as a result of legal challenges that are pending judicial review. The disclosure requirements would apply to the Company's fiscal year beginning January 1, 2025, pending resolution of the stay. While there has been no resolution of the stay, the Company is currently evaluating the final rule to determine its impact on the Company's disclosures.
