With summer coming up and some of the posts about insulating train rooms I thought I'd post this. I'd heard about this 2 years ago but I don't think it was on the market yet. I saw a Bob Vila show this morning where they were using intermodal containers to build homes in Florida. This is all they were using to insulate them in the Fl. heat. Less than 1/4" =R28. This is an off shoot of the stuff they're using to coat the new space shuttles. I know I'm going to look into it. I'd much rather paint something on than attach foam or fiberglass.
