DensDeck Logo

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. DensDeck panels’ superior dimensional stability over competitive gypsum fiber boards is due to their low coefficient of thermal and hygrometric expansion. DensDeck® panels used as cover boards do not need to be gapped. The enhanced boards also demonstrate superior compressive strength to support installation equipment and post-construction foot traffic.

DensDeck roof board, with its fiberglass mats and non-combustible gypsum core* - is resistant to mold growth, and has scored a 10, the highest level of performance for mold resistance under the ASTM D 3273 test method.  With billions of square feet installed over three decades in a complete range of roofing systems and climate extremes, DensDeck® Roof Boards have proven their toughness and versatility.  DensDeck® panels continue to earn industry accolades due to their ability to deliver high quality performance, every time.
