DensDeck Prime is a trusted and durable roof substrate that can be used in virtually any commercial roofing system. DensDeck Prime can mitigate the risk from fire, foot traffic, and hail damage, helping to add lifespan to the roofing system.

In 2013, Georgia-Pacific Gypsum made several enhancements to DensDeck Prime Roof Boards, and contractors particularly like its ease of handling, easy scoring and snapping with no special tools required -- resulting in less breakage and waste.

The enhanced boards also demonstrate superior compressive strength to support installation equipment and post-construction foot traffic.
