Installation layer

[simpa81]

Hello! I need help getting an answer to a question that has been bothering me for a long time:

I often see in pictures that people build an installation layer on the inside of their walls. This layer often seems to be built with horizontal 45/45 studs.
How do you then attach the drywall to this? If you attach them vertically, there isn't much to screw into? Or do you set another vertical stud?

I may have misunderstood everything, but I've really been puzzling over this for a long time!

This is how you do it, nothing strange about it. Fits just as well.



Not the neatest drawing but you probably understand.

Aha! That will be many screw holes to fill, but I get the principle thanks for the answer, it was quite obvious when I think about it!

It will be the same number of skruv.

Stuck on the left image that seems to depict the option with vertical studs, most of the screws are hidden by the strip where the joints are plastered.

Personally, I first install OSB (or Plywood) horizontally and then drywall vertically, so that the drywall can be screwed into the OSB in the usual way. Technically, you should probably still screw the drywall into the studs, but I primarily screw it in the usual way and reinforce it with a couple of screws along the studs (and, of course, make sure to hit the studs in the actual seam), it's worked well for me without cracks.

I would avoid installing only drywall if possible, it's much easier to put things up with a wood panel behind it.

Exactly, we have placed OSB behind the drywall on the few walls I've worked on. So far, only interior walls

The house will be expanded in the future, so I'm pondering some of these kinds of things.

There are no rules that say you have to screw into the studs, but of course, it's better but then you need the right screw. 29 mm is of no use then.

If you place the boards as in the right picture in post #2, it assumes two layers of boards, i.e., plywood, OSB, or chipboard behind the drywall. Otherwise, you get no support behind the drywall joints. Alternatively, you have to install a bunch of noggings. But I guess there isn't any serious DIYer who installs single drywall without wooden boards behind?

Have 45s lying with OSB on, keep in mind that something is needed to screw the OSB board into at the joints, it flexes otherwise, I realized.
