I have an office that is partially above my garageOne wall is exterior, one is interior and two(plus the ceiling) are built into above the garage atticThis room gets really hot during the summer and really cold during the winterI assume since half of it and the ceiling are exposed to the garage attic, which gets hot/cold easilyI added insulation to the ceilingI want to add insulation to the 2 garage exposed wallsThere is already insulation between the studsIf I try to add more between the studs the insualtion support wires won't hold it in since it's too thickWhat other options are there to help insulate this room better?
