DensDeck® Roof Boards



DensDeck® Roof Board

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

As a thermal barrier, DensDeck panels provide needed fire resistance in FM Class 1 roofing systems. In mechanically attached single-ply membrane systems, DensDeck is ideal as a noncombustible underlayment over the structural deck.

DensDeck roof boards are available across the United States and Canada.

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