guys, I'm looking at a 30x50 pole barn by Hoover Buildings, in Upstate SC. In our region, we have 4 distinct seasons, with high humidity in the Summer. The insulation that they can add as part of a package is rated at R7. This would be in the ceiling and side walls. Is R7 enough to fight condensation issues by itself, or are you guys running a fill ridge vent as well? I don't plan on heating and cooling it mechanically, but would like it to stay reasonable year round.
