USG Securock® Brand Cement Roof Board is a high-performance roof board for use in low-slope roofi ng systems. As the lightest and easiest-to-use cement board in the industry, it enhances the entire roofi ng system as both a cover board and as a parapet, fir e or thermal barrier roof board. As a cover board, USG Securock Cement Roof Board can be used with a variety of membranes and systems including most adhered and mechanically attached systems, but it is ideal for applications such as liquid-applied membranes and cold mastic-modifi ed bitumen. As a parapet, fi re or thermal barrier roof board, USG Securock Cement Roof Board has an unlimited slope classification and is noncombustible. Because this product is cement-based, it provides superior compressive strength, water durability and mold resistance.

USG Securock® Brand UltraLight Glass-Mat Roof Board is a high-performance roof board for use in low-slope commercial roofing systems. It enhances the durability of the entire roofing system when used as cover board in single-ply mechanically attached systems. Its specially treated core and high-performance glass-mat facer provide protection against fire, mold and moisture.

USG Securock® Brand UltraLight Coated Glass-Mat Roof Board is a high-performance roof board for use in low-slope commercial roofing systems. It enhances the durability of the entire roofing system when used as cover board in low-slope commercial roof systems. Its specially treated core and high-performance glass-mat facer provide protection against fire, mold and moisture.USG Securock UltraLight Coated Glass-Mat Roof Board combines superior strength and an ultralight core applicable for all cold adhesive roof applications.

USG Securock® Brand Gypsum-Fiber Roof Board is a high-performance roof board for use in low-slope roofing systems. Its unique fiber-reinforced, uniform composition gives the panel strength and water resistance through to the core. USG Securock Gypsum-Fiber Roof Board provides exceptional bond and low absorption in adhered systems and, with uniform composition, achieves high wind-uplift ratings with no risk of facer delamination. Made from 97% recycled material, USG Securock Gypsum-Fiber roof board combines superior performance with sustainable design for all types of built-up roofing systems and most fluid applied, spray foam, metal and any polyester reinforced single ply or modified bitumen membrane systems.

DensDeck® StormX™ Prime Roof Board is a reinforced gypsum panel with enhanced moisture resistant core and coated glass mat facers. DensDeck StormX Roof Board is extremely durable and is approved for use in assemblies meeting FM Very Severe Hail (VSH) Classification*, while still maintaining the highest level of moisture resistance through the use of GP’s patented EONIC™ Technology. In fact, DensDeck StormX was the first gypsum cover board to meet FM VSH classification under a single ply membrane, and the first to do this under a 60 mil TPO membrane (no fleece) as well. Choose DensDeck StormX Roof Boards for adhered and self adhered “peel & stick” roofing systems, as well as hot mopped, cold mastic and torch-applied modified bitumen roofs. DensDeck StormX Roof Boards create a more resilient installation by enhancing the overall strength and wind resistance of an assembly, increasing the puncture resistance of the membrane, and providing hail protection to the membrane, insulation, and total roof system.
