Abstract: An insulated window panel is provided with pseudo sash bar lattices that are affixed, preferably by dual-sided adhesive foam tape, in coincidental alignment to the outwardly facing transparent surfaces of the panel. Dual-and triple-glazed window panels constructed in accordance with the present invention have the appearance of being constructed of a plurality of small panes or panels that are surrounded and held in planar array by sash bars. The resemblance to French-style windows is achieved by means of a remarkable trompe l'oeil effect that results when pseudo sash bar lattices are affixed in coincidental alignment on opposite sides of the panel. Also disclosed is a novel triple-glazed insulated panel wherein the insulating peripheral seal is protected by providing a central pane with slightly reduced height and width dimensions relative to those of the two outwardly facing panes.
