Timber Framing - Stud Spacing To Match OSB And Plasterboard

[Wendelspanswick]

New to the forum, I'm part of the way through my build which is being done on a shoe string budget.

I am doing everything myself and after some advice.

I am building a 2 storey steel framed barn/workers rest area, 10m by 5m.
The ground floor is a traditional block/cavity/block wall (nearl done) and the 2nd storey is going to be timber framed resting on the outer leaf of the ground floor blockwork.

If I space the studs on 600mm centres this works for the plasterboard 1200mm wide but means every OSB sheet (1220 wide) needs 20mm trimming off?

Yes, rip the width and length down if you already have the boards, or source some metric ones.

If the walls are just one board high, you might be able to leave them 2440 high as the extra bit goes over the sole or top plate.

That's exactly what you have to do I'm afraid. You always end to work to the plasterboard. One day the USA will metricate and we'll have metric plywood
.

You could use OSB 3

 

[tomfe]

Even osb is 8x4 not 1.2x2.4

 

[catlad]

OSB 3 is 18mm 2400x600 T&G

OSB 3 is 18mm 2400x600 T&G

600 mm wide sheets are unlikely to provide the required racking resistance. Unless bonded across the whole elevation.

It has a structural grade of class 2

 

[^woody^]

That does not matter

All the OSB3 I have priced up is in 8'x4' sheets.
Even Wickes sell OSB3 in imperial sheets marked up in metric sizes.

Lol I can just imagine gluing all those joints.

@Wendelspanswick find a builders/ merchant with a table saw to rip them down for you. It might cost you 50p a cut or something but they will be able to do lots of sheets at once. Then you can just get on with it.

 

[Wendelspanswick]

Shouldn't be too bad, it's about 30 sheets of OSB so if I stack them in piles of 5 I can run the handheld circular saw down a batten to trim them.

Wandel you need to understand who you are dealing with if you are buying your stuff from wicks they probably think imperial and metric is the same thing.
Tomfe I stopped using 8x4' sheets about 10yrs ago I was only trying
to make you aware there was a better alternative.
