Help address concerns for fire safety by promoting increased fire resistance in your residential construction. ToughRock® Fireguard 45® Gypsum Board is manufactured to meet ASTM C1396 Sections 5 and 12. Its dimensionally stable gypsum core is noncombustible as described and tested in accordance with ASTM E136 and UL-classified Type FG for use in select fire-rated wall assemblies.1 In third-party testing, wall assemblies with 1/2″ ToughRock Fireguard 45 Gypsum Board lasted longer than assemblies with 1/2″ lightweight gypsum board.2

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.

Since 1/2″ (12.7 mm) ToughRock Fireguard 45 Gypsum Board is a heavier product, the sound resistance of the wall or ceiling may be better if it is used in place of 1/2″ light weight gypsum boards. Many factors affect the sound resistance of your wall including the spacing of your studs, the type of studs, the use of insulation or resilient channel, the spacing of fasteners, etc. In independent lab testing, 1/2″ (12.7 mm) ToughRock Fireguard 45 Gypsum Board wall assemblies performed 1 – 4 STC better than comparable assemblies constructed using 1/2″ lightweight gypsum boards.
