Hello everyone,
I have a question. What is the best way to build a non-load-bearing interior wall in terms of sound insulation?
My carpenter suggested using KVH beams measuring 6x8 cm (2.4x3.1 inches), with 12 mm (0.5 inches) OSB panels on both sides and 12.5 mm (0.5 inches) drywall, resulting in a wall thickness of 13 cm (5.1 inches). Another person uses 28x78 mm (1.1x3.1 inches) boarding as studs – although you have to be very precise when screwing on the OSB panels in that case. Yet another option is using CW metal stud profiles; he said they transmit less or even no sound compared to wood. Is that correct?
Best regards

Basically, you can keep in mind that sound is reduced by mass.
Conclusion: I think the carpenter’s solution is the best, although I would use 15mm OSB and make sure that the KVH (timber frame) is straight! Otherwise, you’ll end up with a warped wall. It’s actually better to use BSH (glulam beam). It may cost 1-2 euros more per meter, but it’s straight and doesn’t warp as quickly.
That way, you can also attach something to the wall later, even as a non-professional, using regular nails or screws without wall plugs.
