I wonder if anyone has comments about my unconventional thinking here. I have a bead on good priced 1x8's. I thought to sheathe the wall studs (horizontally) with them instead of 4x8 OSB or whatnot. I suppose I have to think about shrinkage or expansion between such boards. I don't think I want to clapboard them since I may put a layer of rigid insulation outside this with a final siding outside of that.
Anyone with ideas of what I might expect and what I might want to think about with such a strategy. The idea is to leave the inside "unfinished" with exposed studs.
I get started with my build on Thursday.

If you do that you will need to let-in some diagonals on the inside of the studs. That's needed to keep the walls from racking. OSB serves as a shear diaphragm but 1x8s run horizontally don't.
As to your question, if you just butt the boards with straight edges together, you are going to get cracks between them with changes in humidity. Do a shiplap edge on them.

Tyvek or roofing felt would be wise as well.

You could run them on a 45* angle too.
How cheap are these boards if a sheet of OSB is $10?

It's less a matter of price than it is aesthetics where I'm not drywalling or panelling on the inside. I don't want to look at OSB or plywood interior walls. I like the diagonal idea.

O I missed that part about not finishing the interior.
You could also do a double angle. It would look like a V from the inside. Tar paper on the exterior so if they shrink u see black.

Yeah, doubt it would pass code, No shear strength. If its the look your after, sheet it with OSB (hate strand board, love plywood...) and then barrier and your horizontal, but that would be extra work when T1-11 would get you shear wall plus finished covering in one swoop.

Or you could sheath it with T1-11 with the good side in. I did the kitchen roof in our cabin that way and I really like the way it came out.

Good side in prob wouldnt pass code either. Nor would no insulation.

No inspections where I'm at. Which has its pros and cons, mostly pros. As mentioned above, I'd be adding another (exterior) siding layer with a bit of insulation sandwiched in between.
