Owens Corning announced that it has completed the acquisition of insulation manufacturer Thermafiber Inc. The acquisition, which includes a 145,000-square-foot manufacturing location in Wabash, Ind., provides Owens Corning with a broad insulation portfolio now encompassing fiberglass, foam, and mineral wool insulation products. “The acquisition of Thermafiber is an outstanding addition for Owens Corning and our customers,” said Joe Ochoa, vice president and general manager, Engineered Insulation Systems. “Mineral wool insulation adds to our product portfolio and helps us to provide access to high-temperature commercial building applications.”
