Renovation gypsum and width

[nimhed]

Hello
I'm wondering why renovation plasterboard is often only sold with a width of 900mm. That measurement only works if you have framing at 300mm centers, which is only applicable for ceilings. The usual on walls is either 600mm or 400mm centers.

Byggmax has it in a 1200mm width, but I am much closer to Bauhaus, K-Rauta, and Hornbach. None of these have a width other than 900.

Is it that it's intended for ceilings to such a large extent that it justifies this limited range of widths, or is there something I have missed?

I never use the 6mm plasterboard unless I have to, but sometimes you have to.

Well...
Personally, I don't know in what cases you have cc400 in the walls.
Either you have cc600 which can then be complemented with studs in between, turning it into cc300.
In newer houses, it's more common to use cc450 because the 900 gypsum is being used more and more as it is easier to handle.

However, I have no reasonable explanation for why 6mm is so hard to find in 1200 width.

I'm working on my mother-in-law's townhouse from the 60s, and the interior walls have studs at cc400.

Do they really frame new houses with cc450? I thought the insulation still dictated, gosh, having to cut the insulation.

Ok...I've actually never encountered that.

I don't build new houses, but this is what I've heard, and from what I understood, there is apparently insulation available that is adapted for this today.
