By weight modern homes here in SoCal are largely steel reinforced wood structures.? I manage some properties in the Pasadena area and one of my jobs are the improvements, I oversee lots of ground up work.? There is very little foam used at all and all fresh water and gas lines are copper or steel.? AFAIK the only plastic material used are for in wall electrical insulation and a single small HVAC drain.? Roofing is largely engineered plywood with the one place where petrochemicals are commonly used in asphalt shingle and treated paper.? But many roofs are concrete shingle for fire resistance.? Not sure what that guy was talking about.??
