Saving heat equates to saving energy.

The fine air pores of the natural pumice stone provide ideal heat storage, whilst its temperature balancing properties ensure a healthy indoor climate.

The heat transfer coefficients (u-values) of the wall elements, which are already at a high level, can even be further optimised by use of additional core insulation.
