Polyurethane foam insulation
I have come across a beautiful sailboat that has been insulated with sprayed on Polyurethane foam. Some reviews call it solid gasoline for its fire risk, releases cyanide gas on ignition and soaks up water like a sponge.
Is the one used in boats a special non flammable type?
Does this sound like a good idea or just a way to cover problems?
