I finally have a 30x40 garage. It's a metal with wood posts and trusses. It's not done yet, still waiting for the doors to be installed, 2 8x9 overhead insulated. Ice on the ground, so couldn't install em on the 13th. Looking for the best way to insulate it, other than spray foam, anywhere 5-10k for that, and would have to wait till warmer weather. Since the wifey paid for the building, least I can do is pay for most everything else. The posts are 8' on center, trusses are 4'.
