Process for making a paneled wall having abutment joints sealed by a dual gasket assembly

A process for making a paneled wall having sealed abutment joints, the wall comprising a first wall panel module comprising a first wall panel and a dual gasket assembly, a second wall panel, and a sealed abutment joint between the first wall panel and the second wall panel,

• wherein the dual gasket assembly comprises a compressible interior gasket, a support coupling, and a compressible weather gasket,
• each of the first and second wall panels being rectangular and having a vertical height, a horizontal width, and a thickness, and each of the first and second wall panels further having a first major face and an opposing second major face,
• each of the first and second wall panels additionally having a plurality of edge faces, each edge face having a length that is either a) the vertical height of the first or second wall panel or b) the horizontal width of the first or second wall panel, and each edge face having a width that is the thickness of either the first or second wall panel, with each edge face being generally perpendicular to both the first major face and the opposing second major face of the first or second wall panel,
• the process including the steps of:
• a) attaching the dual gasket assembly to one of the plurality of edge faces of the first wall panel to form a first wall panel module,
• b) aligning the second wall panel relative to the first wall panel module such that the first major face of the first wall panel and the first major face of the second wall panel lie in the same first plane, and the opposing second major face of the first wall panel and opposing second major face of the second wall panel lie in the same second plane, forming a set of parallel major face planes, and
• c) compressing both the compressible interior gasket and the compressible weather gasket of the dual gasket assembly between one of the plurality of edge faces of the first wall panel and one of the plurality of edge faces of the second wall panel to seal the abutment joint between said edge faces.
