1/2 in x 4 ft x 8 ft GP DensDeck Prime Roof Board


DensDeck® Prime Roof Boards have been enhanced with EONIC™ Technology, a patented system that delivers advanced moisture performance and mat-to-core bond strength.

With this advancement, DensDeck® Prime Roof Boards are now the only roof board with manufacturing specifications that include 5%1 total water absorption by weight and 1 gram2surface water absorption performance on both sides of the board.3 Also improved is the boards critical mat-to-core bond strength which in independent testing4 averaged 23% stronger on the face and 192% stronger on the back when compared to DensDeck® Prime Roof Boards before the enhancement.

DensDeck® Prime Roof Boards continues to provide a broader compatibility and higher performance with roofing adhesives. Face mat allows adhesives to be applied more uniformly and consistently and results in a stronger bond with the membrane. For fully adhered and self-adhered “peel & stick” roofing systems, as well as hot mopped, cold mastic and torch-applied modified bitumen roofs, DensDeck® Prime provides a stronger, more economical installation by reducing the amount of mastic or adhesive, and potentially eliminating the field primer. Consult with membrane manufacturer for actual priming requirements.
