Is the following wall design good or bad? I’m looking for a tight wall with no air infiltration. Poll.,ADA ect. seen awkward and I really question their intactness with time. I’m considering a standard 2×6 24oc with a twist.When 2 framing members touch 1 of them is a 2×4 flush to the outside. You never let 2 2×6’s touching.This gives you a 2″ air space between the back of the 2×4 and the exterior sheathing. Now we fill the cavity with foam-including behind the 2×4. This eliminates air infiltration that would orrur if we have 2×6’s adjacent to one another. Good idea, bad idea? Yes, I know this is an expensive design and no, stress skin panels are out because the design is too chopped up. To quote congress: “What say you all”? Thanks for the feed back.
