Vapor Control Layer in Climate Zone 6?
I am building a new home in northern Vermont (climate zone 6) and have the following wall section from outside to inside:
LP Smartside Board & Batten siding
3/4″ PT vertical furring strips
Rainscreen drainage matt
2″ Rockwool rigid insulation
Henry Blueskin VP 100 self adhering rain barrier
1/2″ CDX plywood sheathing
2×6 studs at 24″ O.C.
5 1/2″ Rockwool Batt Insulation
1/2″ drywall (air barrier)
My question is do I need a vapor control layer between the wood studs and interior drywall? If so, what product do you recommend?
