Vapor Barrier when using Excel II as Air Barrier

user-5996667 | Posted in Green Products and Materials on

We’re retrofitting a bungalow in Toronto, we’re using Excel II as an air barrier. We want a green product for a vapor barrier. What’s the best product? Would it make sense to use a Blueskin VP as a house wrap?

    According to the manufacturer, BP Excel II serves as an air and water barrier when the joints and penetrations are sealed. Are you thinking of using the Blueskin to seal the junction where the foundation and sheathing meet? Or did you have something else in mind?
