Hello everyone,
I want to section off a bathroom in a room. I have marked the wall lines in red in the picture.
The wall will be 3.40m (11 ft 2 in) high.
For the cladding, I plan to use 15mm (5/8 inch) OSB boards with 12.5mm (1/2 inch) drywall panels on top.
I want to build it with metal UW and CW profiles.

Can you tell me what minimum width the UW and CW profiles should have?

My other questions are:
- Should the OSB boards be installed with staggered joints?
- Do the joints of the OSB boards need to be filled and sanded?
- I have read that you should leave a few millimeters of gap between the boards and the wall/floor/ceiling. How can I seal this gap to prevent sound transmission?

Thank you in advance

Normally, walls are built first, then the ceiling. Exceptions can occur, but these are special cases (if you want to keep flexible rooms, this works better).

And is it okay that the copper profiles do not rest on a continuous surface, but only every 30cm (12 inches) on a 5cm (2 inch) wide cross batten?
