The house I recently moved to has a pole barn about 32 x 36. Concrete floor, brown steel sides, white steel roof. No windows. No vents but also not very tightly sealed. No insulation or wood backing. Moved in last winter, and once it got above freezing during the day while below freezing at night, I would get frost on the underside of the roof panels at night. Which would melt in the day, dripping all over everything. Trails of water in line with the roof supports and all over anything in its path. I have to cover all my things with plastic sheets. Summer was fine, and right now the cold arrived so fast that it probably won't thaw for awhile.
I don't heat the barn and don't plan to. I've heard that spray foam insulation would cost several thousand dollars which is way out of budget. I'm looking for something more economical to stop the frost. It must be condensation that freezes, but there's not enough during summer dog days to make it sweat. Possibly styrofoam board between the roof supports? Or would installing some sort of venting or fans do it? I do have power out there.
