Unfortunately, it's a long road ahead. We have contacted CCMC to try to get some traction and some groundwork done for exactly what you're saying.
To be honest, the challenge is getting architects and designers educated on sandwich construction, especially in composites.
I deal in recycled plastic using fibreglass skins. SIP homes are built with OSB and expanded polystyrene, with OSB skins on the outside. Architects and the Canadian building code are very well versed in that type of construction. I have the same thing, except in my opinion, it's very much more durable and resistant to the elements.
As I said in my introduction, I've built many commercial boats out of the same material. They go on the ocean and get pounded in 20-foot seas for years. The fishermen bring their boat to the wharf and tie it up, and there it is the next day, whereas if you have a storm go through.... You all know the challenges storms give to conventional construction.
As far as the building code goes, here in Nova Scotia I deal closely with building inspectors. We have engineer-stamped drawings on anything we do, because recycled PET plastic is not in the building code yet.
