Foamed Glass UK Ltd | Sustainable Construction Aggregate

Raw glass is conveyed into the plant and a powerful magnet removes and metallic particles which are sent to recycling

The glass is dried and any unwanted material such, as labels and organic residue, is removed. The clean, dry glass is then transferred to the grinding mill in a continuous operation. Filtration systems capture any dust and is fully recycled.

The glass is passed through a high-speed roller mill to form a very fine powder. The particles are approx. 0.03mm size.

The glass powder is stored in one of 5 x silos

The glass powder is transferred to a mixer and a small amount of foaming agent is added. The mixture is then deposited on a slow-moving belt which travels through the kilns in a continuous operation.

The mix is heated in a controlled profile. It semi-melts and begins to expand as fine gas cells are formed. The expanded foamed glass exits the kilns approx. 3-4 times the original volume.

As it cools, the Foamglass naturally cracks and shatters into smaller pieces in the Cooling Zone. At this point once fully cooled, the Foamglass aggregate is at full strength, stability and ready for use.

The Foamglass gets conveyed outside ready for crushing and screening to the necessary grades of size. The resulting product is exceptionally low-weight, strong, angular, clean and a superb thermally insulating material.
