Georgia-Pacific has always made a quality 1/2″ paper-faced gypsum board. In the first half of 2015, Georgia-Pacific Gypsum introduced an upgraded 1/2″ paper-faced gypsum board called ToughRock® Fireguard 45™ Gypsum Board. The improved 1/2” board has enhanced fire-resistive properties and can replace standard and lightweight gypsum board in ALL 1/2″ wall and ceiling assemblies, including 24″ o.c. framed ceilings. ToughRock Fireguard 45 Gypsum Board is a standard weight 1/2″ interior wallboard that has achieved a 45-minute UL classified fire rating in select assemblies (consult local codes for actual requirements).
