Hello everyone,
I hope you can help me. I am trying to decide whether to build my exterior walls with 42.5cm (17 inches) aerated concrete blocks with a lambda value of 0.08 or 0.09.
I am not building to KfW standards, and the heating system is gas combined with solar. Is there a significant difference between the two?
Thanks in advance.

We also have 11 cm (4.3 inches) and 17 cm (6.7 inches) Poroton interior walls; you can’t hear anything through them... who knows what went wrong with the neighbor’s construction.Come on, Lumpi, to be honest, you can hear everything through an 11 cm (4.3 inches) Poroton wall. If someone farts in the next room, you’ll notice it! It’s the same for us, but only with the 11 cm (4.3 inches) walls; the 17 cm (6.7 inches) ones are definitely much better.Bookstar schrieb:

It’s the same in our house, but only with the 11 cm walls; 17 cm (6.7 inch) walls are significantly better. No, absolutely not. I have a home theater, and the wall to the hallway is 11 cm (4.3 inch) thick. You can turn up the volume a lot without it being heard much outside.
Sand-lime bricks are clearly better than Poroton or aerated concrete when it comes to sound insulation.
However, you should try to form your own opinion. As I said, I cannot confirm that Poroton is so thin-sounding that it feels like having no wall at all.
It should also not be forgotten that usually every room has a door, which is typically the weakest point in terms of soundproofing.

Yes.Are there any issues to expect with exterior walls made of Poroton and interior non-load-bearing walls made of sand-lime brick? Is there any significant difference in cost?I will discuss this with the architect.
