Interior vs. exterior air barrier
Wondering what the consensus is on the interior vs. exterior air barrier issue is? I am considering this question in light of a double-stud, dense-pack cellulose wall.
Marc Rosenbaum has indicated that he prefers exterior air barriers, because they are so much simpler to execute (no zig-zagging around floor systems, etc).
Joe Lstiburek’s “Ideal Double Stud Wall” and the Pro Clima engineers have indicated that they feel that interior air barriers create a more durable wall because they prevent humid interior air from convective looping within the wall (if not actually ever leaking to the exterior), and potentially reaching the dew point on the exterior framed wall before making their way back to the interior.
What are people’s thoughts on this, in this particular double-stud/dense-pack cellulose context?
