Abstract: A method is described of making a plurality of window frame members having different end use applications on a single production line. The method comprises the step of extruding from a single die plate a master window frame member having at least two flange portion extending therefrom. The method also comprises the step of cutting at least one flange portion at a predetermined location to create a functional frame member having a specific end use application.

Abstract: An extruded plastic frame window sash in which the frame has a closed hollow body cross section with a recess extending into the hollow body from the outer periphery of the frame. The individual frame members are held together around a window pane by a tensioned band disposed within the recess and engaging each of the frame members. The tension band extends about the entire sash frame and is joined together at its end to maintain the tension in the band holding the frame together. The walls of the recess reinforce the frame members to prevent deflection induced by the tensioned band.
