Exterior Insulation R-Value in Mixed-Humid Climate
We are designing a wall assembly for a new home in Suffolk County, NY, which is a mixed humid climate (4A). One option we are considering is:
2×6 wall with R23 Rockwool batt cavity insulation
rain screen or cedar-breather
1) to avoid a wet wall, what R value should our continuous exterior insulation be for this zone (4A)?
2) Would something like Intello Plus on the interior be wise here?
