Conditioned crawlspace question
I’m building a house in Asheville NC and my insulation contractor has told me that in order for my house to pass the res check, I’ll need insulation In the crawl space ceiling (cold floor) which is fine, however, I’m doing a conditioned crawl with r10 on the walls and wasn’t planning on having any insulation in the joist bays in the crawl. Do I really need insulation in both the floor and walls?
as a side note, it’s 3 stories with 2×6 walls with r19 batts and we’re spraying 1 1/2” of closed cell with 7 1/2” open cell on top for a total of r40
