What is Foamed Glass

Womersleys' supply foamed glass lightweight aggregate.

It is ideal for sub floors and for preventing cold bridging in well insulated new builds, can play an important role by insulating old buildings whilst retaining breathability and is used in many civil engineering applications. What sets Foamit apart from its competitors is that it is manufactured from purified glass cullet which contains no organic material.
