I’m in the process of building my tubular 39x42x12 metal garage. It’s going to be storage for my cars as well as a hobby level workshop. I live in north Texas so the summers are hot and humid and the winters are somewhat cold. I am trying to decide what type of insulation to go with. I’ve read a lot of people saying closed cell spray foam is the best option, but reading on here I see a lot of folks saying spray foam can cause damage to metal surfaces. My end goal is probably to add a mini split down the road and keep the building at a usable temperature: maybe 80 in the summer and 60 in the winter give or take. I’m open to any style of insulation. Fiberglass is obviously much cheaper than spray foam but I also want to ensure I don’t have condensation issues. I do have a vapor barrier under the concrete pad. The building right now is only framed out, I haven’t begun installing sheet metal yet so nothing is out of the question. I’m over budget on what I had planned so cost is somewhat of a factor. That being said I’m only doing this once so if something is a far superior option then that’s not out of the question either. I’d love to hear your thoughts on what my options are and what I need to do to start heading in the right direction. Photo of the shop as it sits
