Is it allowed to splice OSB on the short side without a noggin behind?

[GalliMattias]

New build with high ceiling height. The interior walls have cc 450 standing studs. The OSB doesn't reach from floor to ceiling and needs to be spliced on the short sides. Do I need to screw noggings behind the joints, or will it be stiff/sufficient in rigidity when the plasterboard is added?

It's alright, no need for kortlas

Offset joints (OSB/gypsum), or were you thinking of a general joint? I'm not a craftsman, but would definitely choose the first option.

If you avoid generalskarvar, no kortlingar are needed. Not even at cc-600.

Staggered joints (OSB/gypsum), or were you thinking about a general joint? I'm not a craftsman, but I would definitely choose the first option.

It doesn't really matter if it's 45cc and 90 boards, as long as the gypsum joints are staggered against the OSB. Sure, there is a slight improvement with staggered joints, but nothing that will matter in practice in this case.

Edit we might mean the same thing after all. I first interpreted it as you wanting to stagger the OSB joints against each other.

I offset the joints. It's quite easily fixed. And it always feels best to avoid a general joint.

Yep, I offset them!

It doesn't matter much if it's 45cc and 90 boards, if the gypsum joints are then offset against the osb. Sure, there is a slight improvement with offset joints but nothing that will make a difference in practice in this case.

Edit maybe we mean the same thing, anyway. Initially, I interpreted it as you wanted the joints on the osb to be offset against each other

The two layers should have offset joints in relation to each other. That's what I meant. 😀

Is it common when installing multi-layer wall cladding to offset joints differently? I haven't seen examples of that myself, but as I said, I'm not a craftsman.

The two layers should have staggered seams relative to each other. That's what I meant. 😀

I would think that today it should be standard to always avoid continuous seams. If nothing else, many have probably cursed at cracks in wallpaper above doors and windows after someone ignored it and thought - I will never do that...😂

That's why you always place the drywall so it goes around the corner.

How high is your ceiling?

That's why you always place the drywall so it wraps around the corner.

But shouldn't people have the same dilemma when building stairwells or have open to the ridge?

Both OSB and plasterboard are available in 2800 mm length. As mentioned, it doesn't really matter if you join OSB boards, so going with the cheaper or more accessible boards is fine. However, it can be nice to avoid some of the joints on the plasterboard that must be filled:

Nah, I have plasterboard in the right length - there wasn't much of a price difference and it was available on the shelf at my hardware store. OSB, on the other hand, is a special order item with an unreasonably higher price. So I'm going with 2500 and splicing (after consulting here) since it doesn't need to be supported in that way. Every little bit helps...
