Because this is a commodity it is hard to maintain a stable price structure. Also we would prefer bio-based such as soy, but the price is still too high for this to be affordable to the majority of the building industry and again, we'd be tied to the commodity pricing scale. We are continuiously working in R&D to perfect our SIP system and are actually interested in looking at new and improved products out there that would not be based on the commodities market such as petroleum, lumber, etc. I agree with using a non-petroleum based core.

I love the idea of using straw, but I worry about pests (what better place for a mouse to live), fire resistance, and mold resistance. However, new foams are entering the market using bio based components instead of petroleum. I believe these products will be the future of SIP cores.
