In a wall panel wall system for a building with a plurality of wall panels, each wall panel having an exterior weather surface, an interior plenum exposed surface, and panel side edges extending the preselected thickness of the panels from the exterior weather surface to the interior plenum surface for abutment to similar said panels to form a continuous building exterior wall, and means affixed to the panels for supporting the panels from a structural member of the building. The panels as supported from the building abut to form at least one horizontal or diagonal joint at the side edges between the panels and at least one vertical joint between the panels. A caulking system is provided for the joints between the panels. The caulking system has an elastic gutter support member for forming a barrier between said horizontally or diagonally abutted panels. The gutter support member has a backing portion having wedged placement between said horizontally or diagonally abutted panels and an attached gutter portion extending along a bottom edge of said joint from the backing portion along a preselected thickness of said panels towards and beyond an interior plenum exposed surface of said panels to dispose beyond the plane of the plenum exposed portion of said panels an upwardly exposed gutter edge. The caulking system has at least one weep tube communicated to drain said gutter bottom at one end and extending along said vertical joint to and toward the weather exposed surface of said panels at the other end for discharging water from the interior of said gutter to the exterior weather exposed surface of said panels.
