Timber, 45x45 battens, OSB, drywall?

[Arne999]

I am in the process of completely renovating a house and have just framed a room with 45x45 studs outside the timber. The question now is how I should panel this.

The idea is to use OSB and then drywall, but the purpose of the OSB is really only if I'm going to mount stuff, right? I have timber 4.5 cm behind the drywall, so I should be able to screw in whatever I want anyway... or is there another purpose for the OSB?

The plaster has no bearing strength, so if someone stumbles into the wall, the plaster is likely to break, and I assume the plaster can crack if there is nothing behind it to absorb the bending force.

Ok.. Then you have to stumble a lot but sure, it might be worth buying. A kortlingar should indeed stabilize the plaster quite a bit.

I don't think the timber helps when you're hanging things because it's too far from the drywall. You can screw into the studs and use molly plugs in the drywall. It's more convenient to mount things on the wall if you have OSB behind the drywall, but you can manage without it too. People may have different habits, but I've never thrown myself against the wall so hard that it broke, even with single drywall.

Why are you framing out the wall? If you attach the drywall directly to the timber, the room will be bigger and you'll have proper material to screw into.

You just tear the plaster before it sets if you screw into the timber wall behind.

It is so uneven that screwing directly does not work. Additionally, I am taking the opportunity to install new electrical wiring and flush-mounted boxes require 45mm.

It's so uneven that screwing directly doesn't work. Besides, I'm also installing new electrical wiring, and recessed boxes require 45mm

I mean if you later need to attach things to the timber wall with a cavity behind the drywall.

True.. It will have to be OSB since I'm only putting up these walls once in a lifetime I hope...
