Henry Sperber Receives DOE Grant to Develop Foamed Insulation

Foamed insulation from coal fly-ash, being developed by Henry Sperber of Abiff Manufacturing, recently got a boost in the form of a DOE grant. Sperber is the inventor of the Blow-in-Blanket and Fiberiffic insulation systems. The product has interesting possibilities as a low-cost, foamed-in-place insulation made from industrial waste. It is still two years or more from commercialization, however, and independent testing has not yet begun.
