Abstract
A moisture control dam system for curtain wall structures including spaced apart vertical and horizontal members in a framework for supporting wall panels. The horizontal frame members have an upwardly opening channel for receiving a lower edge portion of the panels and the channel includes an upstanding outer wall, a spaced apart upstanding inner wall, and a bottom wall. The upstanding walls are provided with thickened ribs on the inside surfaces adjacent the upper edges and sealing strips are mounted on the ribs for providing moisture seal around the edges of the outside face of the panel. Each rib projects outwardly of the adjacent inside wall surface toward a rib on an opposite channel wall and a pair of vertical grooves are formed therein adjacent the ends of the horizontal frame member for receiving vertical dams of sheet material that are inserted therein to dam up any accumulated moisture in the channel and prevent the discharge thereof out the end of the frame member. Weep openings are provided at appropriate intervals in the outer wall of the horizontal frame member to drain collected moisture to the outside of the building.
