Nothing like that spray in foam. You shop looks great. I checked on doing my large 3 garage here in Illinois and it was close to your price so I used batt insulation for about half of that which was still too much but I put in a higher R value than was suggested too. However, I never needed to turn on my A/C on my mini-split as it never got that hot inside and always stayed around 72*. If you don't mind me asking, what is your total investment so far?
