Hamilton Robinson Acquires Sound Seal

January 17, 2014 by John McNulty

United Process, Inc. (DBA Sound Seal) has been acquired by Hamilton Robinson Capital Partners in partnership with the company’s management team. The retiring founders of SoundSeal, Barry Lyons and Rich Mulcahy, will maintain an ownership interest in the company.

Sound Seal is a manufacturer of commercial and architectural acoustic noise control products. The company’s Architectural and Flooring divisions provide products used for interiors, and the Industrial division provides products used for community noise, construction noise and in-plant noise abatement. Sound Seal’s products are marketed under the Industrial, Impacta, Woodtrends and Sound Quality brand names. The company was founded in 1978 and operates a 50,000 sq. ft. facility (headquarters) in Agawam, MA (www.soundseal.com).

“We find that Sound Seal’s culture, products, financial performance and focus on delivering world-class solutions is a very powerful combination,” said Chris Lund, Partner at Hamilton Robinson. “We are thrilled to support Sound Seal’s management team in their purchase of the company and to partner with Joe Lupone as he leads the company as CEO in its next phase of growth and development.

Hamilton Robinson Capital Partners invests in small, privately held manufacturing, distribution and service businesses. The firm was founded in 1984 and is headquartered in Stamford, CT (www.hrco.com).

Webster Bank, a commercial bank based in Farmington, CT (www.websteronline.com) provided the financing to support the transaction. Focus Investment Banking (www.focusbankers.com) served as advisors to Sound Seal’s owners.
