Abstract

An exterior curtain wall and window construction for a commercial building is disclosed in which the curtain wall and window frames are secured to the framework of the building thereby to constitute the exterior walls of the building with the curtain wall having window openings therein. The window openings are defined by upper and lower window pane securement frames which have portions thereof in abutting engagement with the outer margins of the window pane at the top and bottom thereof. A removable window securement member may be snapped in place into the upper window securement frame with sealing gaskets interposed between the inner and outer faces of the window pane and the window frame members so as to seal the window pane relative to the frames and to cushion the window pane relative to the frame. A weep tube in communication with the inside surface of the window adjacent the bottom thereof is provided so that condensation or other moisture may be drained from the bottom of the window to a location exteriorily of the curtain wall at a location below the window.
