As fellow GMS companies, Gypsum Supply Company (GSC), Ryan Building Materials (Ryan), and ASI Building Products (ASI) are authorized dealers of Thermafiber® insulation products, through our construction yards across the Great Lakes region in Michigan and northwest Ohio.

The Thermafiber Difference

For decades, the Thermafiber name has been synonymous with innovation and advancement. As a leading manufacturer of mineral wool insulation products, Thermafiber developed the world’s first formaldehyde-free mineral wool solution – a true breakthrough for architects, builders, and contractors pursuing effective, green building standards.

From the very beginning, Thermafiber (an Owens Corning company) has been committed to improving quality and safety, while developing insulation solutions that help conserve energy, control sound, and provide proven fire protection. It’s no surprise you’ll find Thermafiber insulation products in iconic constructions around the globe, including in six of the world’s 12 tallest buildings.
