Hello,
I'm in the process of decorating my upstairs and I'm pondering how to handle the sloped ceiling... There will be masonite boards, 335mm insulation (95+120+120), plastic, and then... either tight spacing with just drywall or "wider" spacing with OSB boards followed by drywall.
Is it necessary to use OSB in the sloped ceiling? OSB + drywall in the interior walls is a given, but is it really necessary in the sloped ceiling? It's hard to hang things on a sloped ceiling...

No, it's not necessary. I actually don't think people usually have anything more than plaster. If it becomes relevant, there are molly plugs to hang something a bit heavier. But sure. If you know you want to mount something like a TV, I would put a bit more spacing there just in case.
We usually space the ceilings 300 c/c and just gypsum..
Just space them out. Place a steel profile in the angle/angles, so you have a better chance of it holding together.
But I would probably have used OSB if I had a broken roof and the lower part is extremely steep, but then better in that particular part.

Thanks for the answers! I'm mostly thinking if one might regret it in the future, but I can't think of a single item you can hang in a sloped ceiling besides hanging lamps. I can't install an air source heat pump, I can't mount a TV (unless it were hung on a long arm, which would look ridiculous), I can't put up pictures, etc.
Tried googling some images but can't find a single picture with anything mounted in a sloped ceiling—except spotlights.
So it seems fairly unnecessary and practically completely useless to have OSB in the sloped ceiling.

You're thinking smart and well!R roniish said:
I consider it very overkill.
Space them with cc300 as usual and then just drywall.
You will have plenty of opportunities to hang whatever is needed in the spaces.

How do you actually place the drywall on the "gles" (sparsely placed support)?
I've always placed it along the length, the opposite of what you would do with subflooring. The long edge then gets support all the way, and the short edge is supported by 4 or 5 pieces of 70mm wide gles.
Maybe it doesn't really matter, I haven't seen any cracks in the ceilings yet...
Now, I'm usually not too quick, so the gles can stay in place for a few weeks before the drywall goes up, or the drywall goes up immediately but the plastering can take time 🙂
