What is cellular glass insulation?

Cellular glass insulation is a thermal insulation category that has recycled glass and sand as base materials, supplemented by mineral substances and other natural materials.

Cellular glass retains its material qualities over many years. Independently tested samples have shown that after 55 years, it is still as effective as the day it was originally installed. When using FOAMGLAS® insulation, early renovations are unnecessary, long term costs are reduced, and energy is saved.
