Moisture Control in this Wall Assembly
I am working on a build in North Vancouver and would like some advice about this wall structure. The goal would be passive house:
1.5″ Roxul comfortboard (R5)
2x6x16″ Roxul comfortbatt (R22)
2x4x16″ insulated service wall (R14)
The house wrap would be a SIGA WRB and Air barrier.
My main concern with this would be water getting into the external wall and with the internal service wall not being able to dry.
Also with the 1.5″ external insulation being so thin, wouldn’t there be condensation issues?
