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

The DuPont Difference

In 1802, inventor, scholar, and gentleman scientist E.I. du Pont broke ground for his first powder mills along the banks of the Brandywine River. More than two centuries later, the company that proudly bears his name is still setting the standard for excellence in industrial innovation.

Now, DuPont is a diversified Fortune 50 company, recognized and respected worldwide as a leader in multiple industries, including quality construction materials. DuPont invented the air and water barrier category more than 30 years ago. Today, Tyvek® weather barrier systems are enhancing quality, comfort and ROI in new construction and remodel/reside projects. DuPont works continuously with architects, builders, and installers on innovative insulation solutions for the next generation of new construction and renovation of existing buildings.
