I think I read somewhere that spray foam insulation was compatible with fiberglass resin. That would be an ideal combination, if in fact it works. I know from experience that styrofoam isn't compatible with resin, infact melts when subjected to resin. Any other materials worthy of consideration?

Open-cell styrofoam can be coated with white glue ( Elmer's ),and then it will tolerate polyester resin for composite layups.Epoxy resin will not attack it.
