Insulation ~ Foamed Glass

A strong yet light insulator, foamed glass is suitable for load bearing applications especially those demanding water and vapour resistance.

Description
Foamed glass insulation is made from (usually) recycled glass that is mixed with carbon and then heated to very high temperatures. Upon heating the carbon oxidises and forms bubbles in the resultant stone-like material. It is usually supplied as a gravel, but is also available in (very expensive) batts.

Features

Performance
Typically in the range 0.037 – 0.048 W/m.K. (Watts per meter Kelvin ~ a lower value is a better result)

Cost
With strength comes cost …for gravel at a depth of 100mm, cost is around £15 per square metre or around £150 for a cubic metre bag.
