Finishing garage for woodworking shop
It's coming along well but I want to do it right and have a few questions:
- The attached (shared) wall is concrete block. I have already installed 2x4 framing in front of it and plan to use batt insulation, vapor barrier, and drywall. I'll also be filling any gaps with gap filler foam. Do I need a vapor barrier here since the finished inside house wall should have a vapor barrier? I've read not to install a vapor barrier on both sides of a wall as it will trap moisture. But I've also read you want to block all gas/fumes from the garage.
- I have already finished 1 side wall with batt insulation and vapor barrier (no drywall yet). I learned afterwards that I should have used vapor boxes around my electrical boxes (metal). Is it worth it to cut the vapor barrier, redo the electrical boxes with the vapor box, and tape everything back up?
- What is the proper application of acoustic sealant around the vapor barrier? I've seen it done only on the bottom, on all 4 sides of the wall, and even on every stud.
