Abstract
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.

Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
123 words
In an insulated widow panel that includes first and second spaced, transparent panes having corresponding first and second outwardly facing surfaces on opposite sides of said panel, the improvement in combination therewith comprising a first pseudo sash bar affixed by adhesive means to said first surface and a second pseudo sash bar affixed by adhesive means to said second surface in coincidental alignment with said first pseudo sash bar on the opposite side of said panel, the width of said pseudo sash bars relative to the distance between said first and second outwardly facing surfaces being such that said panel provides the appearance of conventional windows separated by conventional sash bars from most viewing angles and from both sides of said window panel.
Claim 2
Dependent Claim
