Noncombustible Gypsum Core Board

Georgia-Pacific Gypsum

ToughRock Gypsum Board has a noncombustible (per ASTM E 136), dimensionally stable, gypsum core. The surfacings on both facings and on the long edges are 100 percent recycled paper. The front facing (side to be finished) and the long edges are an ivory color; the back facing paper is gray. The ends are square cut, smooth finished with no paper facing. The board is a wall or ceiling covering material for use in new building construction or renovation work. It is designed for direct attachment (screws, nails or adhesive) to wood and metal framing or existing surfaces. It may also be used as a covering material for flat or curved structures. The facing material may be formed to a curve with a short radius. The board is manufactured with a ivory paper facing designed to receive joint treatment, paint, wall covering, textured coatings or other finish treatment.
