*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.

Product FAQs

What happened to Georgia-Pacific's regular 1/2" gypsum board?
Answer

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). For additional information concerning fire ratings and fire safety, go to www.buildgp.com/safetyinfo.
