Closed cell foam
I am in zone 1 in Louisiana. Is the safest option for a conditioned attic closed cell foam and say rock wool against the foam? I would prefer the flash and batt. My roof assembly is as follows; 26 gauge galvalume 8/12 pitch. Screwed to 2×4’s. 30lb. tar paper under 2x’s and 3/8” plywood attached to rafters. Rafters are 2×6 furred down to accommodate R38. There is living area upstairs.
