Metal stand or wooden stand

Moinsens,

at some point we want to convert our unfinished upstairs and I am quite willing to learn, so I just want to inform myself in time and not do immediately what is common around here without questioning it. Here, timber studs with 5 x 8 KVH are always built with the following setup: 1.25 cm drywall, 1.5 cm OSB, 8 cm separation board as insulation, 1.5 cm OSB, 1.25 cm drywall. In the bathroom with 2.2 cm OSB, so that a heavy wall cabinet with a sink can hang there. I don’t think it is 100% optimal in terms of sound insulation.

How was it done with you and how satisfied are you with it? My girlfriend is rather sensitive to noise.

Would 11.5 aerated concrete also be an option?

No idea, we said for the structural calculation for our wooden beam ceiling that we would use drywall later. Therefore, we are now fixed on dry screed and cannot use wet screed. As I have learned, not the right decision either, but it is common here if it is not being finished immediately. Maybe you can make sense of the data to see if aerated concrete would be possible as well









Although I wouldn’t use 11.5 cm aerated concrete anyway. Rather 11.5 cm sand-lime brick.

With the same "infill" of the profiles and the same cladding, I don't see there being a world of difference between metal rails and squared timber.

Although I wouldn't use 11.5 cm aerated concrete anyway. Then rather 11.5 cm sand-lime brick.

However, that would be a different weight category, and I read the exclusion of a wet screed as a contraindication.

that's why the question. The frame is probably irrelevant. Wood is easier to work with for the layman and the necessary tools. Otherwise, the construction as suggested.

Ultimately, KS and Ytong are not up for discussion anyway. That wet screed is not possible is my assumption, since only dry screed was considered. Whether it really isn't possible, I would probably have to ask the structural engineer. Ultimately, I am looking for feedback on how it has been implemented by others and how satisfied they are with it. Construction boards like Knauff Diamant/Silentboard are not without reason
