I'm in Canada, not Alabama, but I would say that yes, you should use a vapour barrier. A properly sealed vapour barrier will prevent drafts from getting into the house. Remember to install it on the warm side of the wall to prevent condensation inside the wall cavity.

So I guess it would be fair to say it’ll be hot or warm most often, but potential to totally flip
