FWIW, my crawlspace isn't insulated and I notice a lot of air being transmitted thru the floor. There is one area that is about 12 sq. ft. that is still orig tongue n groove, everything else has 3/4" T&G subfloor over it. I will be insulating the floor, but I need to replace the old galv. water pipes with Pex first.
