New to the forum here, so I hope I'm in the right section.
I am in the process of setting up a new partition wall at home in the apartment. It will connect to an existing aerated concrete wall that is 95 mm thick.
I'm thinking 45x70 studs and drywall. The question is how to use OSB/plywood so that the wall doesn't exceed 95 mm. My idea was to place it "internally" between the studs on, for example, 45x45 studs that are attached to the 45x70 stud. See attached horizontal section. It actually feels like a somewhat strange solution.
Does anyone have experience with this solution? How much space does an electrician need for outlets, etc.? Is 45 mm enough? Is there another more common/better solution? Better to place both OSB/drywall on 45x45 studs? The wall height is 2.70.
Hello,
I have installed 45 metal studs and then OSB and gypsum board in an overlapping manner. It turned out stable and good, and it's more than enough to accommodate boxes and conduits for the electrical wires.
I chose 45 metal because it's usually straighter than 45 wood.
However, it took me longer to frame with metal than with wood, but everything takes longer when you're doing something for the first time.

Thanks for the response! It's definitely an option. Not much experience with metal studs, but as you say, it just takes a little longer the first time. My concern with installing 45 wooden studs was that it would become a bit "flimsy." Are metal studs much stiffer?
Osb is 11mm, so installing between the studs becomes quite cumbersome. I once built with 45-studs, a wall where a kitchen would be hung... it was therefore very important that it was stable.
The solution is to glue the boards. Glue osb to the studs and glue gypsum to osb. And screw as usual. It becomes incredibly rigid.
It is faster to build with metal studs and it creates less mess inside an apartment; with a good sheet metal shear and a pop rivet tool it is very easy. There are also telescopic studs that you don't even need to cut to length.
I say like the others, build directly with 45-regels.
Something that makes a big difference for stability is to place crossbars between the reglar. So place two horizontal pieces between each regel so that the wall forms a grid. It makes an enormous difference compared to just having individual standing reglar. If you want to make it even more luxurious, you can set the reglar at cc45 and use 90-boards. This will be a little sturdier than when you go with cc 60.
I have personally built a wall with 45-regels at cc60 and OSB and plasterboard on each side. There is no noticeable difference in stability between it and the other walls in the house.
If you absolutely want to use metal studs, it is possible to glue boards onto them as well, but I believe it will be sturdier if you use wood. 45mm metal is quite flimsy.
Thanks for all the answers! I had already bought a bunch of 45x70 studs, so I placed them on the plate as several mentioned. Really good idea to glue between the OSB and drywall, as it seems to have provided really good cooperation, making the wall quite stiff. I also used 900 panels (because it was easier to transport) and studs at cc450. The wall feels really good!
I haven't done the other side of the wall yet (the electrician needs to come and put in boxes and pipes first), but before that, I will add a layer of insulation.
