Superior Cover Board

DensDeck provides a rigid cover board with high compressive strength to add durability to the roofing system.

Use as specified in FM-tested assemblies to qualify for Class 1 FM Approvals:

Superior Thermal Barrier

DensDeck® provides superior fire resistance — better than wood fiberboard, perlite, high-density polyisocyanurate or gypsum fiberboards.
