Ice and Water Shield for housewrap? #green
I am building a new house in zone 4A. We are using 6" studs and the interior insulation is a hybrid flash and batt configuration with 2" ccsf and 4" fiberglass. Exterior cladding is cedar shake shingles over a rain screen. My GC want to use Ice and Water Shield for the WRB because of the sealing properties from nail penetrations. I do not think it is a good idea, as I think the wall needs to be able to dry to the exterior, and the interior insulation is vapor impermeable. Any thoughts?
