Is it legal to use steel studs for exterior walls? I thought that we established that it wasn't in my Aircrete thread.
Another limitation with trying to retrofit a shed into a home in-town is that sheds probably have 24" studs, on-center. Wouldn't you need 2x6es to make that work?
Can you nail 2x2s to 2x4s and call them 2x6es?
(Maybe 2x3s)
