Is the following wall design good or bad? I am looking for a tight wall with no air infiltration. Poly., ADA etc. seem awkward and I really question their intactness with time. I am considering a standard 2X6 24 oc with a twist. When 2 framing members touch, one of them is a 2X4 flush to the inside. You never let two 2X6’s touch. This gives you a 2″ air space between the back of the 2X4 and the exterior sheathing. Now we fill the cavity with foam including behind the 2X4. This eliminates air infiltration that would occur if we have 2X6’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 feedback.

Sounds to me like you are looking for something that is not going to matter much if your walls are "chopped up" with I would assume windows/doors. I find that SIP's even in these situations if installed correctly are about the best way to go. But as always without seeing a set of the prints we can only guess at what you are aiming for.
