Hello, I have now read a lot about possible wall constructions, there doesn't seem to be the right variant, ok. But if I add up what is recommended (assuming one prefers more insulation rather than less), then I come to about 1 (plaster) + 30 (Poroton) + 18 (rock wool) + 4 (ventilation gap) + 12 (clinker) = 65 cm for a two-shell wall construction with Poroton inside and clinker outside. However, when I google "typical wall thickness" it is rather 49 cm or less (for a "normal" KFW55 or KFW40 house). Where am I wrong? Karl
