DensDeck Prime Roof Board

DensDeck Prime Roof Boards by Georgia-Pacific Gypsum are a patented design features a gypsum core with embedded glass mat facers on the top and bottom of the board. DensDeck Prime can be used in a variety of commercial roof systems and provides an excellent thermal barrier as well as exceptional fire, moisture, and wind uplift resistance properties.

DensDeck Prime is typically used as a cover board over insulation in fully adhered EPDM, TPO, and PVC applications. It is compatible with solvent-based bonding adhesives. For applications in which Helix Max is used to attach insulation and a vapor barrier is specified, DensDeck Prime can be used as a base layer for Mule-Hide’s F5 Air and Vapor Barrier (in conjunction with Aeroweb). DensDeck Prime is also compatible with hot asphalt and can be used as a membrane underlayment in hot mopped roofing systems or as a parapet wall substrate in all systems.
