DensDeck® DuraGuard Roof Board, with fiberglass mats and a noncombustible* gypsum core, is designed to address persistent challenges inherent in commercial roofing assemblies.

DensDeck DuraGuard features a durable, low perm integrated coating. This results in more uniform spreading of the adhesive, excellent coverage rate and enhanced bond strength of membrane system-to-board without the need for field priming*.

It is an ideal panel for self-adhered and hot-mopped membrane systems and can be used under commercial metal and roof tile applications as a substrate for self-adhered secondary water barriers.

This fiberglass mat gypsum roof board is ideal as a component in sustainable, energy-efficient photovoltaic (solar), vegetative and cool roofing systems. DensDeck DuraGuard 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 DuraGuard roof board can add high performance and long life beyond what the membrane manufacturer's warranty will cover.
