Hi everyone I am planning how to make my walls. I have a lot of 1x2 lumber so I want to use that to frame the walls. I am thinking about using the 1/4" birch from HD as the exterior skin. Would this work? I do not see where it says it is exterior grade...so should I use it? I could use the luan they have instead My floor is 10'-0"x4'-6" so I will need to figure out how to mate up the but joint on the exterior wall. Any suggestions or comments?
Thanks
James
