 Gary, we talked about the insulated concrete forms that you can screw the drywall straight to, but I also noticed there's something else. This rim joist is an area that's very often overlooked. It's not insulated or it's not insulated well, people just shove fiberglass insulation in there. Can you talk a little bit about what you're doing here? The old school used to be where they would take fiberglass, put it up inside there, and the only problem with that is moisture will go right through the fiberglass and then it'll condensate or build up frost on the outside, especially in the wintertime when it's really cold. What eventually will happen is that moisture will come out of there and then you have mold growing. The best way to take care of a rim area like that is to spray the foam, like a spray polyurethane foam. What that'll do is that'll create a vapor barrier and it'll keep any moisture from getting through that and then also give you the insulating value that you need in order to stay warm down in your basement. Really for a lot of existing homes, that's an easy way to go back in and have that sprayed because most of them, well, some basements are still open and then you'd be able to call somebody to come in and actually have them foamed for you. That'd be a way to warm up your basement. Then air seal it and insulate it all in one shot. Right, in all one shot, yep.
