The Tyvek would sufficiently serve as our air barrier and WRB, and it experienced the large permeance that we sought after for that “vapor-out” assembly.
a perform with the dew point temperature of the interior air, the quantity of air leakage into your wall, as well as the vapor permeability with the resources in the wall. Tiny quantities of condensation will not be a challenge When the wall is allowed to dry to the exterior.
As we ongoing to more info critique various extended fasteners, most all of which might require some sort of squash block to aid keep uniform depth and guide in lateral bracing, we discovered the Heco Topix-T fastener (see picture under).
