The Manufacturing Process

TECHNOpor® is manufactured from waste glass – glass that is no longer recyclable and would otherwise go to landfill.  In contrast to other glass foam producers, TECHNOpor Handels GmbH, the manufacturers, sort and crush the glass themselves; they, therefore, have total knowledge of, and confidence in, the raw material.  The powdered glass is combined with rising agents and is heated to c900 degrees C – this process is powered by hydro-electricity making the end product zero carbon.  As the material rises in the oven it fills with air bubbles; hence it is lightweight and an extremely good insulator.  And as it cools, as it comes out of the oven, it naturally breaks up into a gravel of randomly shaped granules; TECHNOpor® glass foam granulate.

The end product is then transported to construction sites throughout Europe; it has been used to support railway and motorway junctions in the Alps, to re-structure runways at Leonardo Da Vinci Airport in Rome, and of course to insulate countless buildings on the Continent and, more recently, in the UK.

The raw material: waste glass that is no longer recyclable.

Sorting glass from non-glass.

Crushing glass into a powder.

Glass powder is then heated in an oven powered by hydro-electricity.

As it is an inert material it can be stored outside and it will not degrade.

It can be delivered in bulk or in large bags.
