I have a (currently) unheated Quonset hut, about 30' x 30', with a couple of skylights and a conrete floor.
This summer, we set up a stage and used it as a rehearsal room, which was awesome. You can see it here
. However we've been forced out by the cold. I'm thinking about insulating it and adding some heat so we can use it to rehearse in the winter too, and I assume this would also improve the acoustics, which are not bad when the big door is open, but are very ringy when it's closed.
What's the best option? Spray foam seems good but I worry that the expansion and contraction of the steel would compromise the adhesion. Today I was in a Q hut which had a kind of quilt-like insulation, but I can't find any details online. '
Anyone else insulated a Q hut? What did you do?
