I have a space in my garage that is about 12′ long, and the ceiling is only 7′ high… The floor of this room doesn’t get used very often so I don’t think it’s too hot. It was installed before the house was built, but no one has ever bothered to insulate it because there isn’t enough storage space for all the stuff we need to store here. My question is: how can I prevent this from happening? What kind of insulation would be good enough? Is there something that might be a better option than drywall or other materials? Please let me know what you suggest!
