Air & Water Barrier, a component of the company’s Masonry Veneer Installation System, protects against water intrusion and the effects of extreme weather. It installs behind exterior wall claddings, and can be applied by roller, brush, or spray. When used in conjunction with other construction components within the building envelope, it produces air and water holdout with vapor permeability, and can improve energy efficiencies and indoor air quality.
