Xci VP-SA WRB is a composite membrane designed for use in above-grade wall assemblies to function as a weather resistive barrier. The specially engineered breathable film is fully coated on one side with a permeable adhesive protected with a silicone release liner. The barrier will adhere firmly when pressed against the substrate and will permit the passage of water vapor while performing as a barrier to air and water.

Xci VP-SA WRB is compatible with Hunter Xci polyiso products, the Xci AEGIS Wall System™, and other building materials such as gypsum sheathing, concrete, and CMU. Surface preparation with primer or contact adhesive may be required in certain circumstances.
