With its origins as a roofing contracting business, POLYGLASS® has become one of the world’s leading producers of modified bitumen roofing and waterproofing membranes. Decades of practical experience in the application of roofing and waterproofing materials provide the foundation for the company’s success.

Entering the marketplace by manufacturing modified bituminous membranes in the 1960s, POLYGLASS has since diversified into several production sectors. This practical background, combined with a broad experience in manufacturing, engineering and product development, enables POLYGLASS’® companies to offer a wide range of high quality products to the worldwide residential and commercial roofing market.
