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. It 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 Backs.
