Ice and Water Shield for housewrap?
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?
