Timber framed garage. osb/lining paper covering?

[f0rmula]

What would people suggest is the most sensible way to cover a 6m by 5m timber framed garage?

The garage will be studwork, eventually clad with something like shiplap timber. I think my garage at a previous house was studwork, covered with bitumin lining paper, then clad, but looking around other people also put a layer of OSB in there somewhere. I like that idea because it will add to rigidity and make it easy to keep things perfectly rectangular.

My current thinking is studwork, clad with osb, wrapped in the paper liner, with shiplap on top.

Is this sensible? Can anyone suggest anything better?

Thanks for any advice.

Studs, clad with OSB.

Wrapped in a breather membrane, then battens, then cladding.

Do not clad direct to the membrane.

OK, that sounds sensible. Thanks.

The garage will have a slate roof. Is there one membrane product that will do both underneath the slates on the roof and underneath the shiplap on the walls? Or are they different things?

Also, I look in my loft and there's nothing but felt, then battens and slate. I worry that when the garage is done, if I swing around a big bit of timber (as you do) I could smack the roof and dislodge/break a slate. Would it be wise/crazy to do OSB on the roof too?

Cheers,

Sorry to bump, but it's been a few days. Any comment on whether I membrane and OSB underneath the slate on the roof?
