We have 42.5 cm Liapor walls monolithically as prefabricated elements. Adequate sound insulation goes without saying with this wall thickness, unless you live in Offenbach. The interior walls have a higher concrete content because sound insulation plays a bigger role here than thermal insulation. The thermal insulation of the entire structure is, as far as I can judge so far, very decent. The summer heat protection is at least equally good, not least because of the high internal masses (we have a 20 cm thick concrete wall in the living room and filigree ceilings). The advantage compared to a masonry structure lies in the (slightly) shorter construction time, the very smooth walls, and the fact that you don’t have large cavities in the walls and therefore no problems with drilling, nailing, etc. However, this is also not a big deal in aerated concrete or Poroton if you pay attention to a few things. We decided on this because we simply liked the building material, and that hasn’t changed so far. Disadvantage: you have to know exactly where which switch and which outlet should be located during the planning phase. We would place one or two outlets differently now. Also, you have no flexibility during the shell construction if you suddenly think: “I would actually like the window to be floor-to-ceiling!” Moreover, the building material strongly limits the choice of shell builders. My overall verdict is nevertheless: recommendable
