Re: GBlist: Recycled XPS

Plasti-Fab (div. PFB corp.,Calgary.)manufactures sheets and custom
manufactures a type II EPS that is designed and approved for use below
grade. Pentane is the expansion agent. I've used it extensively below
grade and for flat roof deck applications below concrete. They seem
surprisingly volatile when freshly manufactured but quite inert after
being exposed to air as the specifications say they should be.

Does anyone know if there are any sheet manufacturers for aerogels. I
have a reference for a company called Thermalux in the U.S. but can't
find any information on it.
