This invention relates to exterior building wall systems (10) utilizing multiple wall panels (11) forming horizontal and vertical wall joints (12, 13). Each individual wall panel (11) consists of an essentially flat exterior facing member (20) and four perimeter members (21, 22, 50, 50) structurally connected to the facing member (20). The design of the perimeter members (21, 22, 50, 50) and the combination of differential pressure seals (39, 41) and pressure equalization seals (37, 40) enable the system (10) to prevent water from infiltrating into the building. In addition, this invention is easily disassembled and saves much time and expense.
