ABSTRACT:
A window and portal frame assembly for a building which comprises an elongate inner frame section and pane holding frame section with the portal frame and pane frame section slidingly connected to one another by an intermediate window slide mechanism. Both sections have rigid pronged projections and grooved decorative strips having their grooves cooperatively connected over the pronged projections. In both the frame sections the decorative strips act as a more efficient insulating barrier and in the pane holding frame one of the decorative strips forms one of two opposing abutment surfaces for holding the pane in place in the frame.
