I am planning to convert a space into two apartments and would like tips and advice on how to build the interior walls to achieve good sound insulation.
I was thinking that the studs should be 45*95, 95mm glass wool as insulation. Then OSB board or chipboard, which is better? Chipboard is cheaper. Then 13 mm gypsum board on the outside. Stud spacing is 60 cm.
Is this insulation enough? Should I use less insulation in the walls that do not border the other apartment?
The floor is a cast slab, what's the best way to fasten the studs?
Have I chosen the right materials, dimensions? Or are there other options?

Best answer
I would do it like this:
A "double" wall can be done in a couple of ways. You can place two 70 walls next to each other with an air gap in between, or use alternating studs. The important thing is that a stud in one apartment does not attach to the sheet material of the other apartment, or the sound will travel straight through.
I would use c/c 45 with lightweight studs (in metal), as this allows for more insulation and provides better soundproofing for the wall. Then use double drywall or some other board and drywall, which I would choose depending on what will be placed against that wall when it's finished. Softer materials = less sound. Building with 45 makes it easier if constructing in a basement.
There is no reason to use less insulation; I would say all or nothing.
It's also important to have insulation under the horizontal metal stud (it looks like a foam strip) and those that are mounted against existing walls.
Hope you followed that.

Many times more convenient than the wider ones.http://www.beijerbygg.se/templates/BB_ProduktListing.aspx?id=7370
I'm not trying to push this, but the gypsum costs 7kr more per m² and it's worth it! Just a tip.
There are also insulated rails,
