Improved ToughRock gypsum is now 25% lighter than traditional 1/2-inch wall and ceiling drywall, and features a range of other improvements as well. Greater flex strength makes the boards less prone to breakage during handling, and better sag resistance in ceiling applications means one product can be used on both walls and ceilings. ToughRock is GreenGuard-certified and is designated as low-VOC. Georgia-Pacific | 800.225.6119 | gpgypsum.com
