Below is a table comparing some of the specifications of different foam glass brands.
It is important to understand that since the compressive strength of standard subsoil is around 200 kN/m², this is the limiting factor, not the compressive strength of the foam glass itself. Given that the foam glass has a higher compressive strength than the soil it is resting on, we consider the important value is the Lambda value, which is a measure of thermal conductivity. The lower the figure, in W/mK, the better the insulation capability of the foam glass. Click on the table for a full pdf.
GEOCELL® foam glass aggregate is an insulation material for underground structures. Foamed glass aggregate saves energy and contributes to a comfortable indoor environment. It is both economical and environmentally sound.
Foamed glass insulation aggregate is used in the same way as coated clay aggregate, but is capable of being used as a load bearing hardcore. It also offers better insulation (lambda/k value = 0.08 – approximately 20% better in thermal performance than lightweight expanded clay aggregate). It therefore needs less depth for a similar thermal performance.
✔︎ EXCELLENT INSULATION VALUES
the large number of enclosed cells in each foam glass pellet, ensures excellent insulation characteristics. lambda = 0.08 w/mK.
✔︎ INCREDIBLY STRONG
due to its glass cell structure, GEOCELL® provides excellent compressive strength.
✔︎ NON-CAPILLARY, NON COMBUSTIBLE
cellular glass is comprised of internal closed cells that do not absorb water. Classified as an A1 building material.
✔︎ PERMANENTLY STABLE
stability, durability, resistance against insects and rodents.
✔︎ SUSTAINABLE AND ENVIRONMENTALLY FRIENDLY
made from 100% recycled glass inert and essentially pH-neutral.
✔︎ CE CERTIFICATION
CE mark: GEOCELL® declaration that the product meets the requirements of the applicable EC directives.
✔︎ SAVING TIME AND MONEY
GEOCELL® is quicker to install than conventional methods cutting construction time and cost.
The selection of appropriate insulation material is especially crucial in old buildings. GEOCELL® foam glass combines a drainage layer and insulation in a single product, thus reducing building height. Moreover, GEOCELL® is diffusible, an important property for an insulating material when humidity is an issue. Suitable for thermal insulation under the foundation slab of single/multi family houses, production halls, schools, swimming pools etc.
GEOCELL® is completely unaffected by water and environmentally green. GEOCELL® is made from waste glass that can be reused or recycled at any time.
