SECUROCK® Glass-Mat Roof Board
SECUROCK glass-mat roof board is a high-performance, fire resistant roof board designed for use in low-slope commercial roofing systems. It enhances the durability of the entire roofing system when used as a cover board in single-ply, mechanically attached systems.
SECUROCK glass-mat roof board scores and snaps cleanly and easily, making installation a breeze. And with its high-quality, tight mat, handling is less itchy than competitive products. In addition, its exceptional mat-to-core bond strength reduces the risk of facer delamination when cutting.
SECUROCK glass-mat roof board's specially treated core and fiberglass face and back combine to deliver excellent moisture and mold resistant properties, and it scored a '10' for mold resistance per ASTM D3273.
SECUROCK glass-mat roof board is fire resistant and ideal for use as a fire and thermal barrier. It meets Factory Mutual (FM) Class 1 and Underwriters Laboratories (UL) Class A fire ratings for unlimited slope in fire barrier applications per UL 790.
SECUROCK glass-mat roof board is available in 4' x 8' boards in 1/4", 1/2", and 5/8" thicknesses.
