BlueskinVP is a peel-and-stick membrane that serves as both housewrap and air barrier. Though used in commercial construction since 2009, it is only now coming to the residential market. It requires no fasteners and no taping of seams. You can install it on standard sheathing without any special prep, but if the sheathing is questionable or it’s very cold outside, you can buy a liquid primer that creates a stable gluing surface from the same company. A sill flashing product is also available. The membrane costs 60 to 80 cents per square foot.
