- Insulation as a sound barrier |
Dear Shell, We are renovating our basement and the TV room and a bedroom are below the two upstairs bedrooms. What R-level of insulation would work best to give us a sound barrier? R12 or R20? Thanks, Michael Dear Michael, The following four steps will give you a good sound barrier system. 1. Use R-20 insulation up tight against the under side of the subfloor 2. Apply ½ ” Donnacona under the joist 3. Install acoustical channel 4. Then apply your 5/8” drywall Note: Hot air ducts into the basement should be closed off as they will transfer sound. It's just that easy. Article courtesy of: Shell Busey |
