Moisture-resistant drywall upstairs, requirements?

[Hanna85]

Hi, is there any requirement that plasterboard must be of the "green" type, i.e., moisture-resistant, on the upper floor?

We have received our delivery for a complete house, and on all the green plasterboards it says "upper floor." The thing is, these boards are 260cm, which fits very well on the ground floor since we have a 260cm ceiling height, and 240cm on the upper floor where the regular plasterboard is 240cm. It feels unnecessary to have a 20cm seam just to follow the order list.

No, no difference in floors or even bathrooms exists. Maybe there's just been a mislabeling on the boards, just place them where they fit best.

Precisely, joining gypsum board under 2700 in ceiling height is a big no-no. You should always try to eliminate cross joints.

Then are there different boards for the floors? What brand is it? Gyproc? Knauf/Dano?
What does it say on the back?
Are they all 13 mm thick? Strange with moisture-resistant ones for the upper floor? Is it the type of house where you furnish the upper floor yourself? Then they might have chosen these if it's not heated there.
Weird.

Isn't it lightweight plaster? That is, plaster that weighs less. It is also green in color.
