I am having a ranch home built, with a bonus room over the garage. I plan to use this room as a music/theatre room. What is the best way to insulate and sound proof the room? The builder standard uses R-13 and R-32.
The sheetrock should be doubled on one side of the wall, and type X used. Metal fasteners called resilient channels can be used to separate the single layer of sheetrock from the studs. All passages for sound travel should have at least R-11 insulation in them. Including under the floor. And use those channels to hold the sheetrock off the joists as well.
