converting a large carport into living space… will be building floor with i joists… there is a concrete floor there… the walls will be 2×6 with r6 zipwall and spray foam inside of that …Zone 3. The “crawl” underneath the subfloor will only be ranging from 9 inches to 13 inches. Should I just put batt insulation in the floor joists? or lay rigid foam on the slab under the joists?
