ToughRock® Sound Deadening Board
ToughRock® sound deadening board provides a base layer of sound transmission control in interior gypsum board assemblies, load-bearing wood stud partitions, and non-load bearing steel stud partitions.
It has a noncombustible (as described and tested in accordance with ASTM E 136), dimensionally stable gypsum core, and can be used in assemblies along with ToughRock® Fireguard® and ToughRock Fireguard C® gypsum boards, hence meeting requirements for both sound and fire resistance. Designed for direct attachment (screws, nails, or adhesive) to wood and metal framing or existing surfaces, the ends of the drywall are square-cut and the surfaces of both faces and on the long edges are made of 100% recycled paper.
