Question

I am having a home built and would like the interior walls insulated to help reduce sound. Some people have discouraged this because of moisture. Owens-Corning has a product called QuietZone specifically designed for interior walls. Can standard insulation be used and what are some things I should watch for and request that the builder use?

Putting 1/2" soundboard behind the sheetrock (on both sides of the wall) would probably do a better job of sound attenuation than just putting batts between the studs. Even with the fiberglass in there, the studs themselves would transmit a lot of the noise from one room to the next. One way to reduce this also would be to build the walls with 2X6 top and bottom plates and place 2X4 studs at 8" o.c., with the even numbered studs flush with one side of the plates and the odd numbered studs flush with the other. Then you could weave R-13 between them, but that would be a lot more expensive than using the soundboard. Not familiar with the O/C Quiet-Zone. But if that what's it's designed to do, go to the contractor's desk at your local lumber yard and inquire about it.
