Solar vapour drive a concern? #green

How risky is solar vapour drive in zone 6 toronto which experiences hot humid summers? And increasing occurences of severe thunderstorms? Have what I think is a non-resevoir cladding (2 metal skins with polyiso foamed in btw like a SIP but dependent on caulking at joints, over 2" mineral wool, Tyvek Drainwrap, plywood, 2x6 with mineral wool batt, ? and drywall. Not sure of Tyvek and whether ? layer is needed. Thx.
