Claim:
A method of constructing a wall air barrier system, the method including the steps of: providing a continuous sealing gasket formed from a single layer of substantially uniform material and defining a first portion and a second portion; positioning the first portion of the sealing gasket on a building foundation; pivoting the first portion of the sealing gasket relative to the second portion of the sealing gasket; positioning the second portion of the sealing gasket on a building frame such that the second portion of the sealing gasket directly abuts the building frame; attaching a portion of the building frame adjacent to the building foundation such that a gap is defined between the building foundation and the portion of the frame and that the first portion of the continuous sealing gasket is in the gap defined between the portion of the building frame and the building foundation, wherein the continuous sealing gasket prevents the flow of air in the gap defined between the portion of the frame and the building foundation; and attaching at least one exterior sheathing to the building frame such that the second portion of the sealing gasket is between the exterior sheathing and the building frame.
