Wall assembly/house wrap for zone 5
We’re in a zone 5 where we get 90-100°F high-humidity summers and -10ish winters.
We have walls framed with 2×6 studs and Advantech sheathing. We will be using RockWool in the walls and either drywall or 3/4″ tongue and groove inside. I’m also leaning toward using RockWool Comfort Board on the exterior, then rain screen and Hardie board.
I’m struggling to figure out what the best house wrap/air barrier should be on the exterior and whether I need an air barrier or vapor retarder inside. And should the exterior air barrier go between Comfort Board and sheathing or on top of Comfort Board?
My wife has environmental illness from a moldy house so we’re paranoid of condensation and mold. Thanks for any advice.
