Flash-and-Batt Walls in Cold Climate
We are building a house in Suffolk County, NY, in climate zone 4A. Contractor is wanting to do a flash & batt wall. We are being asked to use the 2018 code, in which I only need to get to R20 in the cavity, but will we have a wet wall without any exterior continuous insulation here?
