Accounting Policies [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation Description of Business Lydall, Inc. and its subsidiaries (the “Company” or “Lydall”) design and manufacture specialty engineered filtration media, life science filtration media, industrial thermal insulating solutions, automotive thermal and acoustical barriers for filtration/separation and thermal/acoustical applications. Basis of Presentation The accompanying Condensed Consolidated Financial Statements include the accounts of Lydall, Inc. and its subsidiaries. All financial information is unaudited for the interim periods reported. All significant intercompany transactions have been eliminated in the Condensed Consolidated Financial Statements. The Condensed Consolidated Financial Statements have been prepared, in all material respects, in accordance with the same accounting principles followed in the preparation of the Company’s annual financial statements for the year ended December 31, 2014 . The operating results of the Industrial Filtration segment have been included in the Consolidated Statement of Operations since the date of acquisition, February 20, 2014. The operating results of the Life Sciences Vital Fluids business have been included in the Consolidated Statement of Operations through the date of disposition, January 30, 2015. The year-end Condensed Consolidated Balance Sheet was derived from the December 31, 2014 audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Management believes that all adjustments, which include only normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position, results of operations and cash flows for the periods reported, have been included. For further information, refer to the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 . Recent Accounting Pronouncements Effective January 1, 2015, the Company adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2014-08 “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The Company evaluated the impact the adoption of ASU 2014-08 had on the Company's consolidated financial statements and disclosures related to the January 2015 sale of its Life Sciences Vital Fluids business and determined that the sale of this business did not qualify as a discontinued operation.

Business Combinations [Abstract]
Acquisition and Divestiture	Acquisition and Divestiture Divestiture On January 30, 2015, the Company sold all of the outstanding shares of common stock of its Life Sciences Vital Fluids business, reported as Other Products and Services, for a cash purchase price of $30.1 million (including a post-closing adjustment of $0.2 million ). The disposition was completed pursuant to a Stock Purchase and Sale Agreement, dated January 30, 2015, by and among the Company, and the buyer. The Company recognized a pre-tax gain on the sale of $18.6 million , reported as non-operating income in the first quarter of 2015. Net of income taxes, the Company reported a gain on sale of $11.8 million . In April 2014, the FASB issued ASU No. 2014-08, and in accordance with the revised accounting guidance for reporting discontinued operations, the Company did not report Life Sciences Vital Fluids as a discontinued operation as it would not be considered a strategic shift in Lydall's business. Accordingly, the operating results of Life Sciences Vital Fluids are included in the operating results of the Company through the sale date and in all periods presented in 2014. Acquisition On February 20, 2014, the Company completed the acquisition of certain industrial filtration businesses of Andrew Industries Limited, an Altham, United Kingdom based corporation. The Industrial Filtration business serves a global customer base in the manufacture of non-woven felt filtration media and filter bags used primarily in industrial air filtration applications including power, cement, asphalt, incineration, food and pharmaceutical. This business, which strengthened the Company’s position as an industry leading, global provider of filtration and engineered materials products, added complementary and new technologies and diversified the Company’s end markets and geographic base. The Company acquired the Industrial Filtration business for $86.9 million in cash (including cash acquired of $7.5 million and a post-closing adjustment payment of $0.2 million to Andrew Industries Limited) and with no debt being acquired. The purchase price was financed with a combination of cash on hand and $60.0 million of borrowings through the Company’s amended $100 million credit facility. The following table summarizes the fair values of identifiable assets acquired and liabilities assumed at the date of the acquisition: In thousands Cash $ 7,493 Accounts Receivable 26,779 Inventory 25,046 Other current assets 2,894 Property, plant and equipment 38,780 Deferred Taxes 2,501 Intangible assets (Note 4) 5,596 Goodwill (Note 4) 3,943 Total assets acquired 113,032 Other liabilities (18,002 ) Deferred taxes (8,130 ) Total liabilities assumed (26,132 ) Net assets acquired $ 86,900 The following table reflects the unaudited pro forma operating results of the Company for the quarter and six months ended June 30, 2014 , which give effect to the acquisition of Industrial Filtration as if it had occurred on January 1, 2013.

Debt Disclosure [Abstract]
Long-term Debt and Financing Arrangements	Long-term Debt and Financing Arrangements On February 18, 2014, the Company amended and restated its $35.0 million senior secured domestic revolving credit facility (as further amended May 5, 2015, “Amended Credit Facility”) with a financial institution and two additional lenders, increasing the available borrowing from $35 million to $100 million . The Amended Credit Facility is secured by substantially all of the assets of the Company. The maturity date for the Amended Credit Facility is January 31, 2019, at which time amounts outstanding under the Amended Credit Facility are due and payable. The Company entered into this Amended Credit Facility in part to fund a majority of the purchase price of the Industrial Filtration acquisition. Under the terms of the Amended Credit Facility, the lenders are providing a $100 million revolving credit facility to the Company, under which the lenders may make revolving loans and issue letters of credit to or for the benefit of the Company and its subsidiaries. The Amended Credit Facility may be increased by an aggregate amount not to exceed $50 million through an accordion feature, subject to specified conditions. The Amended Credit Facility contains a number of affirmative and negative covenants, including financial and operational covenants. The Company is required to meet a minimum interest coverage ratio. The interest coverage ratio requires that, at the end of each fiscal quarter, the ratio of consolidated EBIT to Consolidated Interest Charges, both as defined in the Amended Credit Facility, may not be less than 2.0 to 1.0 for the immediately preceding 12 month period. In addition, the Company must maintain a Consolidated Leverage Ratio, as defined in the Amended Credit Facility, as of the end of each fiscal quarter of no greater than 3.0 to 1.0 . The Company must also meet minimum consolidated EBITDA as of the end of each fiscal quarter for the preceding 12 month period of $30.0 million . The Company was in compliance with all covenants at June 30, 2015 and December 31, 2014. Interest is charged on borrowings at the Company’s option of either: (i) Base Rate plus the Applicable Rate, or (ii) the Eurodollar Rate plus the Applicable Rate. The Base Rate is a fluctuating rate equal to the highest of (a) the federal funds rate plus 0.50% , (b) the prime rate as set by Bank of America, and (c) the Eurocurrency Rate plus 1.00% . The Eurocurrency Rate means (i) if denominated in LIBOR quoted currency, a fluctuating LIBOR per annum rate equal to the London Interbank Offered Rate; (ii) if denominated in Canadian Dollars, the rate per annum equal to the Canadian Dealer Offered Rate; or (iii) the rate per annum as designated with respect to such alternative currency at the time such alternative currency is approved by the Lenders. The Applicable Rate is determined based on the Company’s Consolidated Leverage Ratio (as defined in the Amended Credit Agreement). The Applicable Rate added to the Base Rate Committed Loans ranges from 15 basis points to 100 basis points, and the Applicable Rate added to Eurocurrency Rate Committed Loans and Letters of Credit ranges from 75 basis points to 175 basis points. The Company pays a quarterly fee ranging from 20 basis points to 30 basis points on the unused portion of the $100 million available under the Amended Credit Agreement. At June 30, 2015 , the Company had borrowing availability of $57.7 million under the Amended Credit Facility net of standby letters of credit outstanding of $2.3 million . The Company has a capital lease agreement for the land and building at the St. Nazaire, France operating facility, included in the Thermal/Acoustical Metals segment, requiring monthly principal and interest payments through 2016. The capital lease provides an option for the Company to purchase the land and building at the end of the lease for a nominal amount.

As such this debt would be classified as a Level 2 liability within the fair value hierarchy. The weighted average interest rate on long-term debt was 1.4% for the six months ended June 30, 2015 and 1.5% for the year ended December 31, 2014 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate was 33.6% and 31.3% for the quarters ended June 30, 2015 and 2014 , respectively, and 35.1% and 38.2% for the six months ended June 30, 2015 and 2014 , respectively. The difference in the Company's effective tax rate for the quarter ended June 30, 2015 compared to the quarter ended June 30, 2014 was primarily due to a less favorable mix of earnings in the second quarter of 2015 compared to the second quarter of 2014 derived from countries with lower tax rates compared to that of the United States, including the impact of valuation allowances on certain foreign deferred tax assets. The Company's effective tax rate for the six months ended June 30, 2014 was negatively impacted by discrete income tax charges of approximately $1.0 million primarily for non-deductible transaction related expenses associated with the acquisition of the Industrial Filtration business. The Company and its subsidiaries file a consolidated federal income tax return, as well as returns required by various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities, including such major jurisdictions as the United States, France, Germany, China, the United Kingdom and the Netherlands. With few exceptions, the Company is no longer subject to U.S. federal examinations for years before 2010, state and local examinations for years before 2002, and non-U.S. income tax examinations for years before 2003. The Company’s effective tax rates in future periods could be affected by earnings being lower or higher than anticipated in countries where tax rates differ from the United States federal rate, the relative impact of permanent tax adjustments on higher or lower earnings from domestic operations, changes in net deferred tax asset valuation allowances, the impact of the completion of acquisitions or divestitures, changes in tax rates or tax laws and the completion of tax audits.
