I have plaster walls in perfect condition. I need to insulate the exterior walls. I read about soy based foam insulation. I live in Delaware and can not find a cotractor who does soy foam. I was told that urethane foam would damage plaster due to the expansion of the foam. Soy based expands less and does not damage the plaster. Anyone know where I can find a contractor that does soy based foam. Pat
