Here are some green product developments I’d like to see in the New Year

I spend a lot of time writing about innovations in the building industry—the cool stuff that’s coming out all the time. But I also like to think about what’s needed: stuff that’s not (yet) on the market or performance levels not yet available.
1) Rigid insulation with no flame retardants and insignificant global warming potential
We've been highly critical of the brominated and chlorinated flame retardant chemicals added to nearly all foam-plastic rigid insulation today as well as the high-global-warming-potential blowing agents used in extruded polystyrene (see Can We Replace Foam Insulation?). I would love to see affordable alternatives. They could be new formulations of polystyrene or polyisocyanurate that doesn’t require flame retardants or inorganic materials that are inherently noncombustible (see our review of cool new products from Greenbuild for some advances). I’m intrigued by advanced ceramics and could imagine a foamed ceramic insulation being developed that meets these criteria.
