Exterior wall monolithic with lightweight concrete (Liapor)

We built in 42.5 monolithic according to KfW 70 and are still very satisfied after one year (thermal insulation - as far as can be judged from the electricity consumption of the heat pump so far, sound insulation, etc.).

More detailed data would be interesting. I have also posted mine here in the forum, which might be good for other users to compare and see real values. Maybe then some with gas etc. will also post, so at least a rough comparison can be made.

I think the idea is good. However, we are still missing 7 months to the first year. Our values regarding gas consumption in the new building are therefore not usable, but maybe [Mycraft] will provide theirs.

Here in our region Oberbergischer Kreis, a lot is built with pumice. This behavior cannot be understood in forums. Usually, aerated concrete or bricks are used. What is the reason for this actually?
