I would like to use R11 faced insulation (with vapor barrier) to help deaden some sound from room to room in my basement. Is it ok to use the faced kind with vapor barrier (per code)? I just think that it's easier to staple it to the studs than to press fit between the studs.
Yes, but it won't help much for the sound transmissions. Solids, like the studes, carry most of the vibrations anyway. If you have the space available, you can layer homasote or foam board under the drywall to isolate the studs from the vibrations, or youi should frame a party wall
