Hello, I have a questions regarding finishing below grade walls in zone 5. We have been researching the correct steps to finishing these walls but seem to get different answers depending on whom we ask. I went to our county and state code websites but didn't get clear answers there either. I would love to get some feedback to hopefully simplify the answers for us. Thanks for your time!

1. Is it best to leave a gap between the framing and the concrete below grade wall?
2. What kind of insulation is best, Styrofoam, spray foam, etc for below grade walls?
