AIR AND WATER BARRIER ARTICLE INCLUDING INELASTIC POROUS LAYER

The air and water barrier article includes a polymer-coated inelastic porous layer including a water-vapor permeable polymeric coating disposed on at least one major surface of the inelastic porous layer and an adhesive disposed on a major surface of the polymer-coated inelastic porous layer. The inelastic porous layer can include at least one of surface-modified fibers or natural cellulose fibers. The polymer-coated inelastic porous layer can at least one of a water strike through time of not more than 180 seconds or an absorbance capacity of at least one-half gram per 116 square centimeters. The adhesive may be exposed, in contact with a release surface, or adhered to a surface of a building component. A method of applying the air and water barrier article to a surface of a building component is also disclosed.
