*FIRE SAFETY CAUTION – Passing a fire test in a controlled laboratory setting and/or certifying or labeling a product as having a 45 minute 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 45 minute 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.

Product FAQs

What is the STC for 1/2" (12.7 mm) ToughRock® Fireguard 45® Gypsum Boards in wall assemblies when compared to 1/2" (12.7 mm) light weight gypsum boards on the market today?
Answer

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.
