Insulation - WDVS - with Multipor

Hello There are more reasons for an ETICS, increasing the indoor wind temperature for comfort, "hiding" settlement cracks or eliminating construction faults like thermal bridges that lead to mold. I also like the aerated concrete stuff, it doesn’t burn and is non-toxic and the knock test sounds more solid and not so hollow. However, it is simply too expensive for me and to an unjustified extent. If I calculate normal Yyton used as a wall block, it is much cheaper. But that is heavier and doesn’t insulate as well. But why 120mm? With a 36.5cm Poroton wall according to the energy-saving ordinance, that seems rather exaggerated. Also consider the loophole effect / bunker design. I have an 80mm polyurethane material as ETICS and I’m happy about the high insulation value with the unspoiled facade. The windows have been recessed a bit but it hardly shows. The light the windows let in hasn’t decreased at least I don’t notice it. I used 80mm Multipor in the area of the external chimney because it is thermally harmless if the chimney emits some warmth. It is easy to work with. The only thing to consider is the absorbency when the base coat plaster is applied, it is quite intense and you have to prime. There I see the next disadvantage, the workers are unfamiliar with the exotic building material as ETICS and are accordingly inexperienced which will surely increase the error rate during processing.
