GEOCELL Foam Glass

GEOCELL foam glass aggregate is an insulation material for underground use. Recycled foam glass aggregate saves energy and also contributes to a comfortable indoor environment, an ecological alternative for insulation to building floors.
Foam glass aggregate is available in 1m³ and 2m³ bags, but can also be supplied loose in quantities up to 90m³ for larger projects (dependent on access). Please get in contact with our friendly team to discuss the most suitable options for your project. (Please note delivery prices are postcode specific and can vary.)

Foam Glass Uses

Foam glass aggregate (or gravel) is quite versatile because of its unique lightweight, load bearing, draining and insulating properties providing a sustainable replacement for conventional building materials.
Foamed glass aggregate is a ecological construction material that can be used for:

Foam Glass Properties

  • Aggregate size – 10/60
  • Minimum compacted depth – 120mm
  • Compaction – 1.3 : 1 (30%)
  • Excellent thermal resistance capability – Certified conductivity of 0.08 W/(mK)
  • High compressive strength – 275 kN/m²
  • Light weight – Approx 150 kg/m³
  • Closed cell – Non-capillary
  • Fire resistance – incombustible Class A1

The Production Process of Foam Glass

Foam glass begins as post-consumer recycled glass. Glass of all colours is cleaned to <1% non-glass to eliminate contaminants that may alter the consistency of the finished product. The cleaned glass is milled into a superfine powder, which is then measured and mixed with a foaming agent prior to being kiln-fired.

Once the glass powder mixture is prepared, it’s deposited onto a chain link belt, which moves slowly through the kiln at a specific thermal profile to slowly heat the glass. The glass softens as it heats up, causing a chemical reaction that results in the mixture foaming up and creating a network of closed cell micropores.

After exiting the kiln, the mixture emerges as a thick foam glass slab. The slab quickly begins breaking and cracking due to thermal stress from the exposure to ambient temperature air. Over the next few minutes of cooling, the aggregate pieces continue to fracture until the particle sizes are 2-3 inches in diameter. At the far end of the cooling table, pieces are discharged onto a conveyor system, where they’re sent to bagging or storage
