Looks like Bud was right after all.

Not only is there drywall.. but I also caulked every crack i could find hoping that like people like Bud had said that an air barrier was possible. it's not. Hot air inside - cold air outside only needs a millimetre hole like from an old screw or like the giant gap between the wall and foundation shelf along the wall. a thousand and one places for air to get sucked up and impossible and silly to try to plug them all. And I didn't even want dry wall i had to put it in because of the fire code. So not only did have an ugly drywalled garage, but now it's crumbly wet plaster sandwiched between 2 pieces of paper. Huge mistake. Now if i have to use foam, and i don't like to because its so flammable, i use rigid foam and then just a can of spray foam to seal it. That way i can rip it out if need be. There are so many foam contractors out there pushing the virtues of spray foam. and lobby groups like green building advisor appears to be. beware.
