My garage is attached to the side of the house, and the kitchen wall on the other side is always damn cold in the winter. So, I've been debating adding insulation. My question is -should I insulate all 3 walls, or just the one that meets up to the inside of the house? I don't work in the garage (it's too small, just enough room to fit the car), but I'm planning on ripping out the stucco walls and putting up sheetrock this summer because I hate them anyway, so if they're already open, now's the time to insulate. I just don't want it to get too warm, or trap moisture. What do you guys think?
Here's an old pic of the house, but you can see the layout -
Thanks for your opinions!
