Certainteed Launches New GlasRoc Roof Board

CertainTeed Launches New High-Performance Roof Cover Board with Enhanced Moisture, Mold, Fire Resistance

(Valley Forge, Pa.) – Through the introduction of GlasRoc® Roof Board, CertainTeed Corporation is offering commercial roofing contractors a high-performance alternative to fiberboard and perlite roofing cover boards. Certified by FM Approvals, a leader in certification and approval of roofing products, GlasRoc Roof Board is designed specifically for mechanically attached roofing systems and offers enhanced moisture, mold and fire resistance.

GlasRoc Roof Board features patented Embedded Glass Reinforced Gypsum™ (EGRG™) technology, which combines reinforcing glass mats, fully embedded into a water-resistant gypsum core. This unique technology provides superior durability by preventing delamination of the glass mat facers and offers easy handling with less skin irritation as compared with other glass mat gypsum cover boards. The performance-proven technology is also featured in the company’s existing GlasRoc sheathing and shaftliner products as well as Diamondback™ Tile Backer.

“GlasRoc Roof Board contributes to the overall success of commercial roofing projects through the prevention of moisture and mold damage and enhanced fire resistance,” says Ashwin Himat, director of marketing at CertainTeed Gypsum. “This next generation product also features exceptional compressive strength, which provides superior resistance to damage caused by foot traffic and hail.”

GlasRoc Roof Board offers improved physical performance in comparison to perlite insulation and fiberboard and meets UL Class A and FM Class 1 fire-resistance ratings. The board is lightweight, easy to handle and install, and cuts like regular gypsum board.

GlasRoc Roof Board can be used with various commercial roofing systems, including those from CertainTeed Roofing.

“GlasRoc Roof Board is an excellent addition to our commercial roofing product line,” adds Mark Stancroff, general manager of commercial roofing for CertainTeed Roofing. “By expanding our product portfolio, CertainTeed is strengthening its position as a single resource for commercial roofing contractors.”

GlasRoc Roof Board is being rolled out across the United States and Canada during 2011. For more information on GlasRoc Roof Board, visit
