ATLANTA — Georgia-Pacific Gypsum’s recently enhanced DensDeck^® Prime Roof Board has demonstrated in third-party tests significant attributes that boost jobsite efficiency.

DensDeck Prime ¼-inch fiberglass mat gypsum cover boards demonstrated 2.5 times greater flexural strength, per ASTM C473 test methodology, compared to competitive ¼-inch gypsum fiber boards. The tests were conducted by PRI, Construction Materials Technologies, earlier this year.
