DensDeck® Prime Roof Board, with fiberglass mats and a noncombustible* gypsum core, is enhanced with a green-colored, non-asphaltic coating to allow adhesive to be spread more uniformly. The result is a stronger, more consistent bond.

DensDeck Prime is the perfect cover board for cold mastic, torch applied modified bitumen and adhered single-ply systems. It reduces the amount of mastic or adhesive needed, achieving a more economical installation. It may also eliminate the need for field primer** and may reduce the number of fasteners required to achieve high wind uplift values.

This fiberglass mat gypsum roof board is ideal as a component in sustainable, energy-efficient photovoltaic (solar), vegetative and cool roofing systems. DensDeck Prime roof boards are manufactured in many locations across the United States and Canada, and may contribute to LEED® Materials and Resources certification points.

Approved by leading roofing system manufacturers and consultants, DensDeck Prime roof board can add high performance and long life beyond what the membrane manufacturer's warranty will cover.
