Abstract: 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.

Abstract: There is provided a self-sealing article comprising a polymeric layer disposed on and covering a first major surface of an elastic porous layer, wherein the article passes Modified Test 1 of ASTM D-1970/D-1970M-13 or Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-13, and further wherein the self-sealing article is water vapor permeable and an air and water barrier. There is also provided a linered version of the self-sealing article in which a liner is disposed on a major surface of the polymeric layer opposite the first major surface of the elastic porous layer.
