Foam glass

Foam glass

 Foam glass is light enough to float in water and has been used as a substitute for cork, but its main uses are for thermal and sound insulation. It is impervious to moisture, most fumes, and vermin

Cellular glass insulation is a lightweight, rigid, and durable material composed of completely sealed glass cells. It's non-combustible, provides superior compressive strength, moisture resistance, dimensional stability, and offers long lasting thermal performance.
