Conditioned crawlspace, floor insulation
I think every drawing & article I’ve read showed no insulation on the floor of a conditioned crawlspace. So far, I haven’t found any recent info on the heatloss into the ground or temperature of the ground below a conditioned crawlspace. There’s something in my old ASHRAE fundamentals for a basement floor, but it seems too high. It would seem that if there more than a little heat loss it should be insulated?
