Foam glass is the innovation of development insulation; it combines all features of a modern insulation material.

Foam glass is heat insulating, rot-proof, sound-absorbing and adequate for the load application to be used under paving tiles.

With his ideal thermal conductance (Lamda) from 0,076 to 0,085 W/mK and a compression ratio of 1.3:1 - it is a requirement for virtually unlimited heat storage capacity of Sunn-Terra-Therm ® storage system.

With the use of foam glass in the heat insulation, we are using a sustainable resource-saving material.

Especially to build in new construction under the floor slab, as a total system, it is ecologically and also saves construction costs.

Sunn-Terra-Therm ® storage system under new buildings

Modern, highly efficient insulated houses in the low temperature range are with full of renewable energy supply possible.

Not even for priceless full insulating old buildings, at receipt of the heat source, until now.


With the Sunn-Terra-Therm ® storage system we can do!
