A system is provided, wherein the watertight performance of exterior wall perimeters is addressed such as the perimeters of a window, a door, or a curtain wall system. The perimeter sealant lines are classified into P.E. Seal bordering no differential air pressure and D.P. Seal bordering a differential air pressure. Long lasting watertight performance is accomplished by using P.E. Seal in the area of the water path and D.P. Seal away from the water path. The design is accomplished by using combinations of an inner transition member, an exterior perimeter member, pressure equalization holes, and pressure equalized wall cavities.
