With a bulk density of merely 120-200 kg/m³ the Energocell® foam glass is a very easy-to-handle product with low transportation costs. By contrast, concrete and stone rubbles are about 8 to 15 times heavier than the foam glass granules. The following examples illustrate well the difference:
- In the case of an 80 m³ trailer the foam glass
cargo is about 9 to 16 tonnes, therefore significant transportation expenses may
For a 15-cm thick layer of concrete rubble or foam glass granules, spread over a 500 m² area one needs about 127 tons of concrete rubble (5 trips) or 9 to 15 tonnes of foam glass granules (1 trip). In this case 4 trips and the costs involved may be spared.
