This June, insulation manufacturer Thermafiber announced its 75th anniversary. Founded as American Rock Wool in 1934, the company’s main manufacturing plant in Wabash, Ind., has served as the backbone for the company’s success. In 1959, American Rock Wool was purchased by United States Gypsum Co.
In 1996, USG sold Thermafiber and since that time the company has been privately held and headquartered in Wabash.
Since the 1970s, the company has been a provider in developing life-safety systems for high-rise buildings that protect building occupants and prevent the spread of fire. Thermafiber insulation products have been installed in five of the seven tallest buildings in the world.
“Reaching this milestone in our company’s history is a true testament to our employees. Over the years, hundreds of individuals have worked together to make this company what it is today. We are very proud of the achievements that have taken place over the last 75 years,” said Steve Edris, president and CEO. “This is a neat opportunity for our current employees to pause and acknowledge the accomplishments of the past. More importantly, it is a time to focus on continually improving our operations, our products and our services to ensure a long and bright future for Thermafiber.”
