Crawl space with closed-cell spray foam
I hate crawl spaces but it seems like I have to. This is in NC on the southern edge of zone 4. A raised slab is going to cost me at least $10k in compactable fill. Maybe I’m beating a dead horse but what is wrong with a vented crawlspace with closed cell foam sprayed to the underside of the floor and no ductwork in the crawlspace?
Thank you everyone.
