Tremco/GP Gypsum Dens-Deck

Tremco/GP Gypsum Dens-Deck® consists of a water resistant, silicone treated gypsum core, faced with embedded fiberglass mats on the top and bottom of the board. Dens-Deck meets ASTM C 1177/C 1177M, the Standard Specification for Glass Mat Gypsum Substrate for use as Sheeting. Tremco/GP Gypsum Dens-Deck is used as a non structural roof board in a variety of low slope roof system configurations. Dens-Deck is recommended as an over-layment board for isocyanurate insulation in cold process BUR and MB roof systems. Dens-Deck can be used as a substrate for Tremco Single Ply roof systems. Dens-Deck can be installed directly to structural roof decks such as steel and wood to improve application of fire resistance properties of the roofing assembly. Dens-Deck is also recommended as a substrate for vapor retarder systems.
