Hi!
I'm wondering about stud spacing for staggered seams. I intend to build a partition wall in a newly built log frame. I have been recommended to first install OSB board and then gypsum board with "staggered" seams. What spacing should the studs be set at? :x

first, you put the first layer of OSB. Split a drywall and start with it. and your joints will be offset
what are the dimensions of the osb and the width of the drywall?
you don't need to worry.
should I get a screw template for you?
(I forgot one thing, you need to have a small gap between the osb.)

Say you use 1200 sheets, then you space them with cc 600. When you start attaching sheets, you place a full OSB sheet flush against the first stud, so it is screwed into stud 1, 2, and 3. The next OSB is placed flush against the previous one, so it is screwed into stud 3, 4, and 5. When you start with the gypsum, cut a gypsum board to start with, making it 600mm wide. You place it flush against the first stud just like with the OSB, but since you've cut the gypsum, it is fastened only in stud 1 and 2. You don't cut the next gypsum and keep the full width, so it will sit in stud 2, 3, and 4. Then you continue with full sheets... Every other stud will have a gypsum board joint, and every other will have an OSB board joint underneath, i.e., staggered joints.
There is some debate about that. In any case, what I've done is screw the OSB into the studs and then attach the plasterboard without regard to the studs, meaning I only screw it into the OSB. It has worked well when I've done it that way.Puskas said:
Some small details.
You should screw the OSB with particle board screws, 30-33 mm long. The screw should be driven so that it is countersunk one or two mm below the surface. (The particle board screw has grooves under the head that countersink the screw in one operation.)
The OSB is laid with a couple of mm gap between each board, otherwise the wall risks warping due to higher humidity.
You can either screw the drywall with 30-33mm drywall screws, or if you want to be a bit overly meticulous, use screws for double drywall (38-40 mm or so) so that the drywall is attached both to the OSB and the studs.
The drywall screw has a smooth underside to avoid tearing the paper. The drywall screw must not tear the paper when you drive it in; if it does, you need to drive in another one a few cm away.
For this reason, you cannot use drywall screws for OSB or chipboard, and cannot use particle board screws for drywall.
I've copied some notes I wrote in another thread, this also applies to you.

Check under installation in the field furthest to the right.
Also note the instructions regarding the cutting of the boards, e.g. no cut edge above the corner of window and door openings.

That gap between OSB can be taken with a grain of salt...
I have built several houses where they are flush against each other and it works just fine.
If you have such high humidity that they swell, you probably have other problems to worry about...
