1. An integrated air barrier assembly comprising:
a board including a first surface and a second surface;
a fastener-sealing layer comprising a liquid-applied coating composition adhered on one of the first surface or the second surface of the board, wherein the fastener-sealing layer has a glass transition temperature of equal to or less than 40° F. such that the fastener-sealing layer is soft enough to seal around a shaft of a fastener and has a thickness ranging from 1 mils to 50 mils, wherein the liquid-applied coating composition comprises at least one of a liquid-applied latex, acrylic, vinyl acrylic, styrene acrylate, vinyl acetate, styrene-butadiene, carboxylated styrene-butadiene, vinylidene chloride, asphaltic emulsion, natural rubber, butyl, chloroprene, vinyl chloride-ethylene, and polyvinyl chloride; and
an anti-blocking facing layer adhered on a surface of the fastener-sealing layer opposite the board such that the fastener-sealing layer is disposed between the board and the anti-blocking facing layer, wherein the anti-blocking facing layer is chosen from a fiberglass mat, an aluminum foil, a fabric layer, or a paper layer, or a combination thereof,
wherein the assembly has an air leakage of less than 0.02 L/sec-m2 as measured by ASTM Test Method E 2178 (2003) at a pressure difference of 75 Pa.
