Planning on insulating a detached garage to use as my gym/workshop. Garage is about 20×24. The walls are pretty straightforward batts with drywall. My concern in the ceiling. I don’t think I want to create an attic space. I feel like I would never go up there and anything I store would be never seen again. I like the idea of having the ceiling open and I could maybe lay a 4×8 sheet and store items in a small area. I just don’t want to close in the entire space. There is no venting in the ceiling from my understanding. Could I use foam board in the rafters? Would it need to be covered? Is there any foam board that would look good uncovered? I feel like pink board would just stick out. Maybe a silver or white wouldn’t stand out. Does anyone have their garage like this, how does it look?
