Yep, thanks... but this method still leaves the Polyurethane foam on the exterior, and leaves the issue of how you seal and protect it. (because it breaks down with UV, some kind of protection is required.) The only problems I've ever heard about revolve around the issue of how the polyurethane is sealed... can the paint/sealant bubble or flake... how often will it need to be reapplied ...are shingles or (best I've heard) metal roofing applied on top, etc. Apparently, this is a more serious issue in areas of high humidity or rainfall... because the poly will rot from UV and absorb significant amounts of water, prematurely destroying the poly layer (and perhaps wicking water through to the concrete below). I've never understood why the soft-coat poly insulation couldn't be placed on the interior surfaces... and the hard-surface concrete on the exterior....
