I have a 14′ X 14′ crawl space with living area above. The crawl space is non-vented and open to existing basement by 2′ x 3′ opening. The floor of living space is insulated by 5″ batts , with vapor barrier to warm side.
I was thinking of adding unfaced batts to floor and adding 2″ rigid foam to crawl spacewalls on the inside.
I was reading other info that only said to insulate walls. The crawlspace is not condtioned except by opening in basement wall.
Crawl space is dry and shows no sign of dampness. There is a vapor barrier on crawl space floor with stone on top.
This started because the living space is cool and I wanted to insulate the two heat runs that supply heat to living space and run through crawlspace.
Any help on correct way to insulate the crawl space or living space would be GREAT.

It can depend on the climate you're in.

What made the teaching of Jesus different and apparently so hard to accept then as now, was that it required a critical reassessment of the structures and values and attitudes of human society as his listeners and followers shared in it.

Thanks for your help on my insulation of the crawl space. I did go to the building science website before I posted my question because it was not real clear on what to do with remodel type of install. I am going to add just rigid foam to the walls and leave current batt insulation in place.
Thanks for your help and responce.
My most terrifying experience recently was when I had to put down plastic on the ground of a crawl space that had about eighteen inches clearance from ground to floor above with only a small entrance to the space. I wore a mask and was hyperventilating and sweating five minutes into the project. And I'm a Vietnam helicopter vet. Funny what makes one panic. But, this was because it was a rental property, and the "state" said it was required. The ground had no moisture, but the man is in charge, right? Insulation around the wall of the crawl space is the better investment.
If your crawl space is open to the basement. You should insulate the walls of the crawl not the ceiling. Right now you have an unconditioned space open to a conditioned one(the basement) creating a heat loss situation.
What I do is run 6mil plastic on the floor and then out 2" rigid insulation on the walls covered by 1/2" drywall for firestop. I install the wall material with foam board approved construction adhesive.
