1" rough sawn pine for small shed sheathing?
I'm considering plywood alternatives for an outhouse I'm building, including using 1x12" rough sawn pine boards instead of plywood sheathing, and putting a rabbet on either end to shiplap them (as well as perhaps a cosmetic chamfer.) My question is, would this be strong enough for a 4'x4' shed/outhouse? I'm pretty sure it would be, but it'd be pretty obnoxious to have to redo it or have the thing collapse.. :P
From my calculations, it'd cost a bit more than plywood, but I'd save because I'd just stain the whole thing and skip the siding!
