Handling 6mm gypsum

[kalubah]

I have installed 22mm raw boards on the inside of my sloped ceiling. On this, I plan to put drywall (to make it smooth and nice and to some extent provide fire protection). 6mm drywall is both cheaper and reduces the ceiling height less than 13mm. But how manageable is it (how easily does it break)? Am I making it unnecessarily difficult for myself if I use 6mm instead of 13mm?

Is 6 mm really cheaper? Consider that the sheet is only 900 instead of 1200. The 7 mm extra ceiling height is probably negligible, and yes apart from the weight maybe, 13 mm is much easier to handle.

6mm is infinitely more fragile than 13mm. The idea with 6mm is probably that it should be glued against an existing smooth wall = it has support behind the entire surface. If you have it on studs, it will be enough to touch it with something hard for a hole to go right through!

Many are against "shrinking" rooms by putting up studs and plasterboard. But calculate the area you reduce. It's less than you think!
edit: 6mm plasterboard is actually more expensive per square meter in all the stores I've seen! (compared to 13mm)

True. Thought it was cheaper. Go with 13mm.

It might be worth considering using 900 mm width even if you're using 13 mm, they are much easier to work with than 1200 mm width, especially if you have to hold them up against a sloped ceiling and screw at the same time,,, just a little tip

In the basement, we have a wall built solely from 6 mm gypsum on two by two studs with a door of 6 mm gypsum on a frame of slats! The least confidence-inspiring construction I have seen in a house...

Have to go against the wind a bit here and say that 6mm renovation plasterboard can take more of a beating than one might think... Or perhaps I handle all materials with excessive care..

I usually use 13 in all respects except when it comes to smoothing out an uneven or slightly rough wall. You can use 6 on the ceiling if there is already paneling or something else unusual in the ceiling.

I agree. The 6mm drywall is tougher and doesn't break as easily as the 13mm sheet. I think it's a different mix in the drywall. But I would never use that sheet alone on a stud wall. However, in this case, it was on a solid wall (raw boards)? Weight-wise, the 6mm is much easier to work with...

6mm is available at 1200, and it is more expensive than 13mm because it is reinforced with some kind of fiber, no problems handling it....

 

[kalubah]

Maybe it'll be 6mm after all then...

Don't know how your stairs look but it was that factor that determined it became 6mm (ROT) for me on the upper floor on the walls.

The downside of 6mm is that they are expensive, sensitive when screwing (the head).

The advantage is that it is easy to carry, hold in place if you are alone.

If you're careful, it's fine to screw in 6mm, but if you glue the board first with something like PL600, you won't need as many screws...
