Hi;
I live in Canada where as you can probably imagine it can get extremely cold in winter. I have an attached garage (no rooms above it) and the side of the garage that's attached to the house is finished, however the two sides that aren't attached are not. I'm thinking of adding insulation to it (R12) and a vapour barrier, but not putting up drywall. Is that safe? Do I have to add drywall as well or am I ok with just the insulation and vapour barrier over it?
Thanks in advance.
