ABSTRACT:
A fixed sash window assembly has a generally rectangular frame holding a pane or panel of glass or other material and installed in an opening in an enclosing wall of a building. The frame includes a sill of extruded metal or rigid plastic material interally comprising a substantially horizontal web having legs depending therefrom to be mounted directly on a window base on the foundation of the building, and exterior and interior flanges extending upwardly from the exterior and interior ends of the web. The exterior flange has its top end portion held against the panel via an exterior sealing strip. A series of drain holes are formed in the web, just interiorly of the exterior flange, for draining the water that may flow through the exterior sealing strip. One of the depending legs of the web, disposed most exteriorly, has a horizontal ledge extending exteriorly therefrom beyond the window base into underlying relation to the drain holes in the web. A wet sealing compound can thus be filled in between the horizontal ledge of the exterior leg and the foundation of the building without the possibility of clogging up the drain holes. The drain holes are further protected against the backflow of water up therethrough by a drain shield depending from the exterior end of the web.
