Are you going to insulate the floor of the second floor?
That's another one of those "hmmmm; let's make sure we have options to consider". We have not completely ruled out polyisoanurate (icenyne) foam insulation. It would put a huge dent in the budget, but the resulting product would be absolutely awesome. That would allow us to insulate all the walls and the floor would require nothing. I'm not counting on this option, tho. If this was the actual house, I would get much more serious on a foam isulation system. That being said, this will likely wind up being a fibreglass insulation job with a plastic vapor barrier. Since I don't plan on heating the entire garage, it will dictate insulation in the second floor framing. This will also provide sound insulation. Besides, we will be required to separate the garage area from the upstairs living space with firerock, so I will have to do all of the work in that area as permanent before I cork it up.
