Garage wall finishing, and a code question
My garage is unfinished. Is drywall the only code approved wall covering? Are there any other options?
If I add drywall is there any reason to add insulation underneath if I never plan to heat it? If I need to add insulation, is fiberglass OK?
Also, a conditioned breezeway connects the house to the garage. I have installed rigid foam insulation on the portion of the garage wall that touched the breezeway, and installed type X drywall over the rigid foam. A potential issue is the attic of the breezeway “opens” to the garage. I can climb a ladder in the garage and directly access the breezeway attic. Does this need to be sealed for any reason?
