Construction of Tall Interior Wall

[teamlundver]

One of our interior walls will be just over 6.5m high and we are now considering what the construction of this should look like.

The wall is non-load-bearing and the builders' supply only has 4.8m studs, so we are wondering if there is an approved construction method that allows us to use these or if we need to order longer studs from somewhere?

Grateful for any help I can get.

On such a high wall, you will probably need to alternate in the middle and use plywood or OSB behind the drywall as well.

On such a high wall, you should probably reinforce in the middle and also use plywood or OSB behind the drywall.

OSB behind the drywall will be throughout the entire extension.

What do you mean practically when you say reinforce in the middle?

Level up to 3.25, new wall plate and continue leveling to the roof.

It is possible to order studs of greater length, it is quite common. They can be finger-jointed, but that's fine. Even if the wall is not load-bearing, certain measures must be taken to prevent it from bowing out. I suggest:
1) Increase the stud dimension, at least 45x145 mm, and strength class C 24.
2) At least three rows of noggings, preferably more.
3) Structural plywood closest to the studs, not OSB. 12 mm thickness is sufficient.

Thanks for the good answer.
The studs in that wall will be 45×195 since there is a metal post that needs to fit inside the wall.

We can fix 3 rows of nogging as well as construction plywood.

We'll have to order the studs then. Feels a bit annoying since it might only be about 4 in that length (slant wall)

Join the studs, but offset the joints so they don't end up at the same height...?

One option is to use glulam. It is perhaps three times as expensive as regular timber, but it is stocked in much larger lengths (usually 6 m), and you can save on a few rows of noggings. Two rows are enough to have something to screw the plywood into. The dimensional accuracy is greater. It's worth calculating.

One suggestion is also to build the wall with steel studs, allowing you to easily make the wall up to 7 meters without either OSB/plywood in the wall. The studs are also available in most dimensions, so fitting your pillar is not a problem.

It will be considerably cheaper than the proposals with glulam and wood studs.

Know that Beijer has 45x195 finger-jointed in 6 and 8m lengths that can be ordered per piece if the store does not have it. It's located in their central warehouse.
