DENSDeck

The TaperedPlus DENSDeck System is a robust coverboard layer with high compressive strength for use in a warm flat roof waterproofing system.

DensDeck® Prime Roof Board is a robust cover board layer with high compressive strength for use in warm flat roof waterproofing systems. It is lightweight, easy to cut and install, providing enhanced durability and point load resistance to the waterproofing build up while also serving as a thermal and fire barrier to a roof and its parapets.

DensDeck® Prime Roof Board has glass mat facings that are embedded into a water / moisture resistant treated gypsum core with a pre-primed surface, aiding waterproofing membrane adhesion. The unique composition offers excellent fire resistance, moisture
resistance, and wind uplift properties.

The product is compatible with a wide range of waterproofing membranes and offers designers and specifiers a non combustible layer for spreading load above insulation products (see ROCKDeck section).
