/diy/ - Do It Yourself

I love near gulf coast. Hot....really fucking hot, humid and windy. Winters will get below freezing like maybe 2-3 times but mostly wet and 50's.
Building a barndominium, metal structure not wood, slab on grade with workshop on 1st floor and living on 2nd floor.
My question is spray insulation with normal batting when I frame it in, or the standard metal building insulation and still bat it in when I frame it?
I have looked up both pro's and con's, but no specific pro's con's for my climate area. Was hoping someone had good/bad experience to help with my decision.
