CertainTeed Celebrates a Century of Building America
This year, CertainTeed Corp., Valley Forge, Pa., joins the ranks of the few proud companies to have reached 100 years of service. Founded by George Brown in 1904, CertainTeed got its start in East St. Louis, Ill., as the General Roofing Manufacturing Co. A decade later, the company slogan - "Quality Made Certain, Satisfaction Guaranteed" - became the inspiration for the CertainTeed name.
The century-old company continues its tradition of innovation and quality design with the recent introduction of several new products to the building industry, including Landmark™ Widetrack QB™ laminated shingles designed with a wider nailing area for greater installation accuracy, and MemBrain™ insulation, a vapor retarder that defends against moisture problems.
