I insulated the garage, sheetrocked with 5/8" and upgraded my garage door to insulated.
I have yet to do the half of the ceiling that was not done for firecode in '01 though.
I did all my sheetrocking and insulation work around the immobile Camaro. Stubborn huh?
Do you have trouble with concrete sweating and all of your metal tools/parts condensating... then rusting?
That happens here when it gets super hot and muggy, and is common in the spring when the frost goes out. Unfortunately it was also a byproduct of when I had big temp swings in the garage with my haphazard method.
I worry a little I will have that again if I don't maintain a minimum heat once I start heating the garage. Time will tell. I just don't want to commit to a setpoint that finances a new wing at Centerpoint Energy HQ with what I spend on my gas bill increase once I go to a gas fired hanging unit.
