ABSTRACT:
A muntin bar unitary frame for disposition in confronting planar relationship to a glass pane to provide a visual appearance of the window glazing generally that of a divided glass assembly. The muntin bar unitary frame has a plurality of bars arranged in a desired pattern, with each of the bars being hollow with an internal central planar strengthening web defining a pair of tubular cavities and with a cross-joint where two bars intersect being formed by cutting of the two bars and reducing the thickness of the central web of the two bars to bring the central web surfaces in juxtaposed relation for bonding of the bars together. The planar walls of a bar for disposition adjacent glass panes each have raised ribs along the edge thereof to prevent contact of the planar walls with the surfaces of the glass panes.
