With its origins as a roofing contracting business, Polyglass became a leading manufacturer of modified bitumen roofing membranes in Europe in the 1960s and introduced its products and technology to the United States in 1992. Since then, Polyglass has grown to be a leading innovator in the roofing industry. Decades of practical experience in the application of roofing and waterproofing materials provide the strong foundation for understanding the importance of contractor satisfaction. Launching innovative technologies such as Polyglass patented self-adhered ADESO Technology in the 1990s positioned Polyglass as a leader in self-adhered modified bitumen membranes. As the company continued to grow, it was acquired in 2008 by Mapei, a global manufacturer of adhesives, sealants and chemical products for the building industry. Since the acquisition, Polyglass USAs headquarters moved to Deerfield Beach, Florida and the company is better positioned globally for growth.
