Xanadu nobody has been able to tell why a foam home cannot be built like this one of 40 years ago but nobody has the credentials to seal a set of plans do YOU?   My thought of using foam instead of concrete over the steel rebar would be easy to have a change of material NOT SO?  Seems nobody knows enough about foam to declare it with a ballistic coating as a roof?
