A single set of extruded profiles is used to construct either type of window. Each window has a main frame including a sill (22), a header (26) and a pair of jambs (24) which are constructed from a single hollow multi-chambered main frame extrusion (21). Each window (20, 90) also includes at least two sashes (28, 30, 98, 100) which are likewise framed by a single multi-chambered sash extrusion profile (31). Other features of the construction kit include snap in glazing profiles (40) which permit the rapid and economical glazing of window panes, snap in guide rails (62) for supporting weather stripping (66) and guiding window sashes (28, 30, 98, 100) to provide extra versatility in the placement of guide rails (62) and weather stripping (66). A unique system for weather stripping at the meeting rails (42) is also provided whereby a slot (80) for holding weather stripping (72) is provided on the rear surface of the meeting rails (42) so that the weather stripping (72) can be wrapped around the end of the meeting rail (42) and secured by frictional engagement between the rear surface of the rail (42) and the window sash (28, 30, 98, 100). |
