CelluZorbe™ HD Soundproofing Backer
CelluZorbe™ HD Soundproofing Backer is the most cost-effective and eco-friendly way to supercharge an existing barrier by adding both STC and NRC. Use the backer board with drywall to increase sound blocking and absorption or combine with plywood to build a silencer box.
Features
- Thin acoustical backer to block sound (STC 15) and absorb sound (NRC: 0.50)
- Made from 50% pre-consumer recycled cellulose fibers that don't itch
- Easy to install to wood or drywall with adhesive
- Eligible for LEED credits
- Class A Fire Rated
