Protects. Conserves. Endures
The DensDeck Prime Roof Board spreads the load and protects the insulation boards underneath. Therefore, it often pays - from a life-cycle cost perspective- to protect the insulation boards with DensDeck Prime cover board.
Added measure of protection
With a compressive strength of more than 3,000 kPa (10 to 15 times that of a standard PIR insulation board), the DensDeck Prime Roof Board adds structural strength to the entire roofing system and helps to absorb the effects of hail, foot traffic and other potentially damaging impacts. Adding a DensDeck Prime Roof Board over mineral wool insulation at least doubles the load capacity.
Outstanding fire performance
The DensDeck Prime Roof Board is an exceptional fire and thermal barrier, due to its non-combustible core and inorganic facer. Fire performance of the DensDeck Prime board has been evaluated using various test standards:
- ASTM E 136: board is classified as non-combustible
- ASTM E 84: flame spread 0 - smoke development 0
- Factory Mutual (FM) and UL approved
- EN 13501-1, Class 1
