Lydall
Lydall traces its roots to 1869, when Henry Lydall and the Foulds family started a needle factory in Manchester, Connecticut. Over 150 years, the company grew through acquisitions, becoming a publicly traded entity on the NYSE (LDL) in 1989 before being taken private in 2021 by Clearlake Capital-backed Unifrax. The firm operates through four segments: Performance Materials, Technical Nonwovens, Thermal Acoustical Solutions, and Interface Performance Materials. These units produce specialty engineered products for thermal/acoustical insulation, filtration, and separation across automotive, industrial, and healthcare markets. Lydall's manufacturing footprint spans North America and Europe, with plants in North Carolina, New York, and the Netherlands (per company history). Lydall does not disclose AUM or total deployment. The company was delisted after its 2021 acquisition by Unifrax, a Clearlake Capital portfolio company, ending its standalone public reporting. No team size or professional names are publicly available. Lydall's key structural differentiator is its history as a long-standing public company that transitioned to private ownership under a private equity-backed platform. Its 150-year manufacturing heritage and focus on engineered specialty materials distinguish it from purely financial family offices.
