I've mainly used it for sheathing and covered it with 30# felt and
siding. Have used it in the shop instead of Sheet Rock as it is better
to fasten stuff to.
Just finished a small chicken coop made of the stuff (primed and
painted inside and out!) and a re-enforcing beam some 18' long to tie
the two walls of my shop and support the (metal - 5V Crimp) roof.
There i ran a 2x10 bottom cord from wall to wall and cut and nailed
and glued triangular sections to the rafters above it and itself, then
ran another 2x10 nailed and glued and bolted to it like a sandwich and
"sandwiched" the rafters above as well. I hope it will tie the tow
walls together nicely and will try removing (it was a pole barn I
expanded) one of the poles that I, now, feel is "in the way."
I think it's best not exposed to the weather as wet, it swells.
