I want to bring the thread back up because I am currently facing a similar question. The discussion here was very helpful. If the thread creator should read this: Did you end up building with PP4? Is the house perhaps already standing, and if so, what are your experiences? Thanks in advance!

Good morning! Yes indeed, the house is standing, we have moved in, and we built with the 36 cm PP2 Y-Tong, some load-bearing interior walls are PP04. Overall, I have to admit that when noise comes into the house, the windows are the weak point. Rely on SSK IV, that helps extremely (we have that in the living room, bedroom, children's room). I would save myself the PP04 in your place, as it also has worse insulation values. What does your environment look like? What are you currently planning? Next to us is a village main street with cobblestones - a 30 km/h one-way zone. Traffic is very manageable, zero at night. You hear nothing from the asphalted road.

I also did the test holding my ear directly to the cobblestone street against the wall (house is about 5 m away). If you concentrate, you can definitely hear it; it also depends on the vehicle. But if you sit 1 m away, it is not noticeable. So that's more something to get worked up about.

We are satisfied with the stone so far, also regarding thermal insulation performance. Our humidity values were also very good after a short time. Alternatively, the T9 from Poroton is pretty cool. If I were to build again, I might choose a sand-lime brick with mineral insulation and clinker. In the end, that is significantly more expensive, and believe me: you don’t think about it anymore when everything is finished.

It’s definitely not as bad as some sometimes make the 36 cm PP02 out to be. And the dB value is not terrible. Of course, the sand-lime brick is better in that regard. But in terms of economic efficiency, aerated concrete is probably hard to beat.

Thank you very much for your quick feedback! That sounds good, then we will inquire about windows with SSK IV from our builder.

I have always rented in the city and mainly want to build a house to find peace there. Naively, I thought that every solid house is also quiet, but as I have already learned, this is no longer quite true because of all our energy standards. Our builder also offered us Ytong 36.5 PP2. In our current apartment (we have been living here for 12 years), we do hear quite a lot from the neighbors (oh, what am I writing, actually we hear everything ;) this will completely disappear in a house and be a huge added value.

We have a rear property, so we do not hear the little-traveled street. Unfortunately, because of the rear location, the neighbors are quite close and of course many more than with a front property. The neighbor to the left, for example, is only 6 meters away from us, has a pool, and likes to ride a motorcycle. The neighbor in front of us is also quite close. In total, we have 3 neighbor houses just a stone's throw away and then 2 quite close as well.

We plan a house with a gable roof and also want to have a central controlled residential ventilation system installed so that we can keep the windows closed. It would be great if I could not hear a garden party of the neighbors or the sweet grandchildren next door at all or, if so, only quietly with the window closed on the ground floor (the upper floor is different because of the gable roof). We ourselves are quite quiet people; the TV or music rarely runs here, and we read a lot. Therefore, it would be nice if it was reasonably quiet in the house.

With SSK IV you have peace of mind. Really good, believe me. The surcharge is a joke compared to KS with WDVS. For us, it was about 60-70 € more per pane.

It is not "louder" monolithically than before, possibly with ETICS yes. However, in a detached single-family house, you "lack" the impact sound transmissions from stairs anchored to common walls, etc. Those who insulate away children's laughter are to blame themselves. Every man is the architect of his fortune can certainly also be applied to joylessness.

Thanks, we'll do that!



I think there is no need to get personal here. It was just an example and need not be nitpicked.
