Background information

Hollow blocks made of pumice are a good way to build very heat-insulating walls. The material contains many air pockets, and therefore has a very low thermal conductivity.

In contrast to many lightweight concrete blocks, pumice consumes very little energy during its production, making it ecologically a very interesting building material.
