National Gypsum has completed its PURPLE family of noise-reducing products with Gold Bond brand SoundBreak XP Ceiling Board. The product is 3/4-inch sound-damping drywall comprised of two pieces of high-density, mold-, mildew- and moisture-resistant gypsum board with a specially designed PURPLE paper, laminated together with a viscoelastic polymer. It installs and finishes like traditional gypsum board and achieves GREENGUARD Gold Certification for indoor air quality. It was developed for floor-ceiling assemblies where airborne sound, such as disturbing voices, and structurally transmitted sound, such as second-floor foot traffic, are a concern.
