Wall Assembly Climate Zone 5
Building in CT (climate zone 5). The wall assembly will consist of vinyl siding, Tyvek wrap, plywood, Knauf Ecobatt insulation, drywall, and latex paint. I believe that codes require a class II or III vapor retarder. I am extremely sensitive to mold. Given a choice between Kraft facing or several layers of latex paint, which is the better option? I plan to use low VOC paint. I’ve called several manufacturers and they apparently do not test permeability for interior latex paints. Will the inspector require perm ratings? The builder will be giving special attention to air sealing including a blower door test prior to drywall installation.
