I havent decided for sure that I am going to use PC, but I am exploring the possibility and if it would work it would be my first choice. But there are several obsticals to overcome to make it (mostly the mixer) and a good mix and/or way to make it waterproof, fireproof and give with the flex without breaking down. Because I want the max Rvalue and lightweight, I think paper and water strictly is the way to go. What about doing it in individual panels instead of monolithic like the bus? Maybe the panels could just be attached to the steel frame with glue, or the panels could be wrapped with that foil bubble wrap and loosly placed inbetween studs? If I made the studs out of PC do you have a suggestion for a mix? Like I said, at this time I am just "exploring" this and am still open to the possibility that I may have no real option other then to do it the conventional way when the time to insulate comes.But I have always liked the idea of PC and always thought one day I would do something with it and this seemed like a good project idea to me to start with.
