With a noncombustible (per ASTM E136) dimensionally stable gypsum core, ToughRock® Fireguard X® Stretch 54® Gypsum Board is specifically designed for 9′ (2743 mm) ceilings with a designated fire-resistant rating.1 The use of 54” (1372 mm) wide gypsum board in this application saves labor and time by eliminating the need to use board to fill the gap left from 4′ (1220 mm) wide board. 5/8″ (15.9 mm) ToughRock Fireguard X Stretch 54 Gypsum Board is UL-classified Type X, and has a flame-spread rating of 15 and smoke developed 0 when tested in accordance with ASTM E84.

*FIRE SAFETY CAUTION – Passing a fire test in a controlled laboratory setting and/or certifying or labeling a product as having a one-hour, two-hour, or any other fire resistance or protection rating and, therefore, as acceptable for use in certain fire rated assemblies/systems, does not mean that either a particular assembly/system incorporating the product, or any given piece of the product itself, will necessarily provide one-hour fire resistance, two-hour fire resistance, or any other specified fire resistance or protection in an actual fire. In the event of an actual fire, you should immediately take any and all actions necessary for your safety and the safety of others without regard for any fire rating of any product or assembly/system.

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).
