Has anyone had their crawl space encapsulated where the crawl space is basically sealed off from the outside elements and does away with moisture/humidity issues. Just wondering about how much this costs?
Don't screw the metal straight to the osb. The screws will eventually back out. I've used pine 1x4's for stripping to screw the metal to. Some say not to use 1x4, but I've never had a problem as long as they're pine. They hold screws good. I even have part of my house roof stripped with pine 1x4's and haven't had a problem.
I like having cross ventilation in a crawlspace. I also use R-19 Batts between the floor joists. If I'm not mistaken, the energy loss through the floor is only 8-10% and if you have carpet and padding then it's not that much. The foam can be sprayed to the underside of the subfloor, but it's more expensive and I don't see it being a money saving move.
