I saw some info a while back on a flat roof coating that was an expanding
foam, probably polyurethane or whatever, that was white and had a pretty
tough skin. I haven't seen anthing on it lately and wondered if the
system has problems that have prevented widespead usage.
I need to externally insulate a flat roof on a small comercial building, and
was considering alternatives to the isoboard method.
Anyone have any experience with it?
