I'm in the process of finishing half of my pole barn to be a shop. I've insulated the walls to R-19 and the cielings to R-38 and will have an 18k btu minisplit on it. Now I'm trying to decide how to seal the door. The door is inside the barn. You walk into the unwarmed (storage) side of the barn and then go through the door into the shop. I don't like the idea of a threshold as I think that is a tripping hazard. I have a large (42") exterior door that I plan to hang there. I just need to decide how to seal the bottom.
Thanks!
