Noise-Dampening Panels

National Gypsum now offers its Gold Bond SoundBreak noise-dampening gypsum panels in a less expensive, thinner 1/2-inch version. The acoustically enhanced panels feature a layer of viscoelastic polymer sandwiched between two pieces of high-density mold-resistant gypsum to achieve STC ratings of 50 or more. The original 5/8-inch panel with Type X core also is available; both are Greenguard certified.
