ComfortGuard Sound-Deadening Gypsum Board is designed to be a highly effective solution to suppressing sound that’s easy to install. The gypsum board features two separate specially engineered gypsum panels, each including a mold- and moisture-resistant core and facers, laminated together using a viscoelastic polymer. The adhesive between the rigid panels effectively interrupts the transmission of noise vibrations through partition assemblies, according to the manufacturer. When tested in accordance with ASTM standards, the panels also provided fire resistance.
