Why not a diffusion port in double stud walls?
Joe Lstiburek came up with the idea of a diffusion port in unvented attic assemblies as a way to deal with rising vapor.
So I’m wondering if diffusion ports cut into the top OSB/plywood gussets that tend to connect inner and outer walls would provide any kind of help with moisture evaporation in double stud walls where sheathing condensation can happen.
Even if the condensation problem tends to come from air leakage and not vapor transfer from the house, would ultra-vapor permeable air-tight diffusion ports help promote sheathing drying in double stud walls?
