Why don't you respond to my criticism ? I tried to communicate with you and weigh the pros and cons. I am not (yet) set on anything. But if you bring up arguments and advantages that are not relevant according to the wall construction values I mentioned earlier according to "u-wert.XXX", then I wonder how we can communicate reasonably here.
So let it be, all the best to you.

A few arguments for the KS have already been mentioned (higher compressive strength, slimmer non-load-bearing interior walls = more living space, sound insulation (also think about washing machines and dryers, etc.), better fastening options...), what advantages would Poroton offer? Apart from the fact that the construction company can cut it more easily.
BTW, no idea if it really depends on the brick, a friend once said something like that, but a colleague built with 36.5 cm Poroton and the house settled so much within 2 years that the interior plaster cracked in a few spots. With our KS, after 3 years we still have no such issues...
