DensDeck roof boards are designed to address fire resistance, moisture resistance, strength, and dimensional stability in commercial roofing assemblies. DensDeck Prime's enhanced surface treatment offers a useful substrate for many adhered roofings systems by allowing uniform spread of adhesives for a strong, consistent bond. DensDeck DuraGuard features a durable, low-perm, integrated coating that works well with self-adhered, hot-mopped membranes and torched asphaltic systems.
Applications: Cover board and thermal barrier board for low-slope commercial roofing systems.
