A relatively high perm pliable moisture barrier material pliable sheet material exhibits a breathable perm value, e.g., over 0.4, that repels liquid water applied to a surface thereof and which permits water vapor to permeate therethrough in response to a pressure differential thereacross to preclude substantial condensation collection in the interior of said wall at the opening while providing a water barrier to liquid water applied thereto is applied to corners of the window opening in a wall as a plurality of corner seals with leg portions for application to the face of sheathing and leg portions for overlying the sill, jambs and head of the opening at the corners. Flanges may be included for sealing the sheet material to an interior vapor barrier material. Sill, jamb and head seals are applied over the corner seals and over the sill, head and jambs to completely seal the window opening with the sheet material.
