Wonder why they didn't just pour the floor. But if there are wood
beams, I'd be careful about adding vapor barrier, as you dont want the
wood to rot. Is there circulation between the crawl space and the
outside, or the inside? You're probably losing a lot of heat through
the ceiling, is there any insulation up there?
