Cellular Glass. What is it?

Cellular Glass is an ecological product made from recycled glass treated at high temperatures and with the latest technologies in a process similar to Nature’s in the formation of pumice stone. It is a totally inert material with special properties to get rid of encrusted dirt, as  natural abrasive and as a thermal insulation material.


Cellular Glass products are made from recycled glass, a harmless to health, hypoallergenic and ecological material. During the manufacturing process we do not use resins or oil based components and we require our suppliers to supply us with ecological products.
