Tremco/USG Securock®
A Fiber Reinforced, Moisture Resistant Gypsum Roof Board
Tremco/USG Securock® is used as a non-structural roof board in a variety of low slope roof system configurations. Securock is recommended as an overlayment (cover) board in cold process and hot applied BUR and MB roof systems. Securock is also a substrate for Tremco single ply roof systems. Securock may be applied directly to structural roof decks such as steel and wood to improve the application or fire resistance of the roofing assembly. Securock is also recommended as a substrate for vapor retarder systems.
Composition:
Tremco/USG Securock consists of a fiber reinforced, moisture resistant gypsum blend that is homogenous from surface to core. The panel surfacing is compressed to provide a low dusting surface, with moisture resistance provided through the use of a silicone based additive. Securock contains 97% recycled material and meets ASTM D1278 / C1278M, the Standard Specification for Fiber-Reinforced Gypsum Panel.
