The top hung sash assembly of the invention comprises a hinge bar and a frame assembly hingedly connected to the hinge bar. The frame assembly includes a head extrusion member, a sill member and two side members with at least one glazing member mounted therein. The head extrusion includes a first flange which defines a recess. Secured in the recess is weatherstripping which contacts the hinge bar when the frame assembly is closed against the hinge bar. The weatherstripping is only partially compressed when the frame assembly is closed against the hinge bar. The invention further provides a window construction and a related method for joining a plurality of window assemblies which properly spaces the assemblies relative to the building opening and each other and which allows for subsequent thermal expansion and contraction while remaining sealed.
