this weekend we plan to insulate the interior walls on the upper floor (wood stud frame, 8 cm KVH) and are wondering whether to fully insulate with 80 mm (3 inches) or only 60 mm (2.4 inches) in order to have an air gap between the OSB boards and insulation for soundproofing.
Or am I thinking about this the wrong way? On the other hand, if you build with lime sand blocks, for example, you also have a solid, continuous interior wall. From my experience in our previous house with lime sand blocks, the sound insulation wasn’t noticeably different from our current wood stud frame wall (I just don’t know what’s inside the lower part of the walls, since that was done by the carpenter, and upstairs we left it open for future work).
What do you think? By the way, we plan to use Rockwool Sonorock (stone wool) for the insulation.

What does the planner say about this (internal thermal bridges)? Regarding building services at an energy-saving regulation standard, probably not that significant, but for a passive house, it definitely is! Philiboy83 schrieb:
...., I didn’t find the soundproofing any different in our previous house with lime sand brick compared to our current timber frame house... How can you judge something that is not yet completed? regards

How can you evaluate something that has not yet been completed?
Kind regards.Please read carefully first and then ask questions.
I will repeat the sentence once more: "It is basically no different than our current timber frame construction (I just don’t know what’s inside the bottom part of the walls, since that was done by the carpenter, and we left the upper part as a finishing reserve for ourselves)."
In other words: We have been living on the ground floor for several years, and the walls are, according to my layman’s experience, completed.
