Engineered to provide superior wind-uplift performance for a wide variety of roof assemblies. The board is formed using an aggregated portland cement slurry with a polymer-coated, glass-fiber mesh completely encompassing edges and both surfaces, to enhance bond strength of membrane systems and gives excellent resistance to delamination.
Provides excellent fire performance with unlimited slope classifications and is non-combustable per UL 790.
Moisture and Mold Resistance:
Cement based, highly water durable board, scored a maximum "10" for mold resistance when tested per ASTM D 3273.
