my wife and I just bought our first house 8 months ago. We have a 2 car garage. The garage is partially sheetrocked (inside wall facing the house and ceiling) and has insulation between the garage wall and my tv den room. The outside wall of the garage and the back part of the garage just show the wall studs. We get tremendous wind and air flow thru these walls. I want to insulate both walls as I want to be able to work in my garage. What type of insulation do I use for the outside walls? Can I get the insulation with paper on it and have the paper face showing IN toward the garage? I will then sheetrock and hopefully the air flow will decrease.
