What's the best way to seal a crawl space and insulate?
Hi I was wondering what's the best way to seal a crawl space and insulate? Currently it is a vented space. Should the vents be closed permanently? The floor joists have batt insulation in them now. I have a vapor barrier with stone underneath and the radon pipe runs through the space as wel and out through my roof. I was thinking about putting foam board on the block wall and sealing the rim joists. But does the batt insulation stay or go if I do that? Will that help with humidity throughout the home? Will it help with temp in the finished room next to it (split level home). Thanks!
