Plaster on sparse panel

[mattiasohult]

Hello,

I am going to mount plasterboard on a sparse panel in the ceiling (not ceiling plasterboard), and as I understand it, it is preferable to join the short sides on the spars, but to me, it feels wrong not to have support under the long sides.

Does it matter to not have support under the long sides? Should you put cross braces between the spars that you only screw the plasterboard into to get a little extra support?

Hi,

I am going to install drywall on the sparse panel in the ceiling (not ceiling drywall), as I understand it is preferable to join the short sides on the sparse, but to me, it feels bad not to have support under the long sides.

Does it matter if there is no support under the long sides? Should you place crosspieces between the sparse panels to provide some extra support?

How is it spaced in the ceiling?

You should have sparse under all joints, both long and short sides.

You have the glesen on cc300 I assume so you can choose the direction. Make sure to offset the seams.

You should have spacing under all joints, both long and short panels.
