Mount plasterboards?

[AoR]

Hello!

Can plasterboards be mounted horizontally instead of vertically? Advantages/disadvantages of each mounting method?

It works, but there's no point since it only becomes harder with spackling. The idea is that they should go from floor to ceiling.

Hello!

The problem is that the wall is longer than the distance between the floor and the ceiling, but drywall might be flexible enough to "bend" in anyway?

Cutting them is not an option, is it?

 

[snickarboden]

AoR>Maybe easier if you post the measurements here and also the rule distances.

Hello again.

Cutting will happen one way or another.
Old house, so there's a plank wall behind, so just hammer away with abandon.
Between the floor and ceiling, it's ~210cm, but the plasterboard needs to be 2-4cm longer because there's a gap by the floor and ceiling.
I will probably go with horizontal plasterboard at the bottom and vertical on top of that. I think there will be the least amount of cutting that way.

Possible, but usually you want it to be as easy as possible when spackling.
I would have placed the gypsum boards standing and screwed them.

If you join cut boards, bevel the edge a bit, it's needed for the spackling.

Is it easier to plaster vertically instead of horizontally?
I still need to cut the boards even if they are standing and will have to plaster just as much if not more that way?

Stand the boards, they are made to be mounted vertically. If you lay the boards down, you'll have a lot of "short side seams," and it's much more work to get these even/invisible than the normal factory-beveled edges. In other words, you'll have a much more difficult prep work if you lay the boards down, and I can also imagine that the "short sides" won't be even if the plank wall behind isn't 100% even/smooth = very high spackling consumption. The gypsum boards have suitable dimensions as well if you use 900x2400mm boards, then screw them into the plank wall with 450mm c/c, and it should be fine.

hempa: Old house and upper floor gives about 210 cm ceiling height, but you mentioned something about the chamfering and I had completely missed that, so it will probably have to be standing then.
If you go with 1200*2400, do you go 300mm c/c or is 600 enough?

Out on the chamfers and a screw line in the middle of the plasterboard should be enough...

 

[hempa111]

Out in the joints and a row of screws in the middle of the plasterboard should be enough...

screwing c/c 600 mm is perfectly sufficient for strength/stability.

Between screws on the outer edges at 200mm centers in the middle row 300.. Screws approximately one centimeter in from the edge...

Eh, what the heck, read here (it says almost everything you want to know):
