As you know, gypsum board is a good way to add mass to a wall. It's heavy, it's cost effective and it absorbs sound well. ComfortGuard takes it to another level. Designed from the ground up to be the best sound-resistant gypsum solution out there, ComfortGuard features two separate Type X gypsum panels, each including a mold- and moisture-resistant core and facers, laminated together using a viscoelastic polymer. With this pliable adhesive between its two rigid panels, ComfortGuard turns a normal wall into a highly noise-resistant wall with STC ratings raging from 50-70 with no extra effort or special tools. Just score deeply, snap and hang - no saw required. Plus, ComfortGuard adds fire, water and mold resistance, as well as an impressive recycled content making your project that much greener.
Sound Ratings and Transmission
When tested in a basic stud wall assembly in accordance with ASTM C423, a wall built with ComfortGuard produced an STC value of 47 compared to a value of 30 for standard gypsum board. ComfortGuard is over 50% more effective at reducing sound transmission than standard gypsum panels. FIG. 1
Used in a range of common sound wall assemblies, it can help deliver optimum STC ratings more easily and cost efficiently than double stud or staggered wall construction - and there's no risk of compromising the sound protection performance as with resilient channels or clips. ComfortGuard is a much simpler sound design solution than changing wall configurations and eating up valuable square footage.
ComfortGuard is the ideal material for schools, hotels, hospitals, multi-tenant commercial or residential construction - or any project requiring a high level of sound protection as well as outstanding fire and mold resistance.
