Stabilize thin interior wall...

[FrippeFlyer]

Hello.

I'm a bit uncertain...
I need to reinforce an interior wall in an old summer cottage.
Originally, it had:
Tretex - vertical rough sawn boards about 22mm - Tretex
I plan to keep the Tretex (which is the interior wall on the other side) and the rough sawn boards. The question is, how can I best stabilize the wall? I would prefer not to make the wall too thick.
Tearing down and building a new wall with 45x45 is not an option at the moment...
So...
Double OSB before the surface layer (plasterboard)?
Single OSB and double plasterboard?

In short... what stabilizes best?

Probably don't quite understand. Is the wall made up of only standing 22mm raw planking and tretex on each side?

I vote that it's much the same. Do you want to work with more plasterboard or OSB?

Physically, a heavier material (plasterboard) should dampen sound better than a lighter one.

Whether that makes any practical difference in your case, I am skeptical.

Maybe a sandwich of plasterboard/OSB/plasterboard is better than OSB with double plasterboard.

But again, much the same in practice.

I probably don't quite understand. Is the wall just made up of upright 22mm plank and tretex on each side?

Yes.
Correct.

I vote that it's six of one, half a dozen of the other.

Maybe a sandwich with gypsum/OSB/gypsum is better than OSB with double gypsum.

Thanks for the response...
I'm also thinking about the weight, if it's a disadvantage to have too heavy material in the wall. It will be the standing raw board that has to take the weight...

Yes.
Correct.

everything becomes flimsy, even 45x45 is flimsy. It’s not a wall, more like a partition. Anyway, if you want to stabilize it as much as possible, I would use plywood in front of OSB every day of the week, much more torsional rigidity. Preferably two layers, one vertical and then one horizontal. Finish with gypsum standing. Then you get shifted joints and panel effect. However, it would have been cheaper to just build a new wall.

Well, imagine that you've glued together several drywall sheets to make one thick piece. It will be able to support its own weight if you stand it upright.

The best thing is to tear down and build a more stable 70 x 45, but if you want to go with a smoother solution, I would probably use Osb and then plasterboard, offsetting the joints. Good luck

Osb and gypsum are already overkill in a cabin with the described wall, in my book.

Steel plate, glue plasterboard on each side. Done!
