Abstract
An insulated window panel assembly for use in window and door assemblies having an improved insulating spacer between the window panes comprising the panel assembly. At least two panes of glass or other panel material are interconnected in parallel, spaced relationship by a spacer assembly. The spacer assembly is preferably a single length of tubing, generally rectangular in shape, having an outer wall of a first width interconnected to an inner wall of less width by generally concave sidewalls. The sidewalls also contain a bead of sealer material configured to seal with the adjacent window panes. A secondary seal is deposited on the outer wall and overlaps the sidewalls to also form a seal with the window panes. The spacer assembly is preferably one piece, bent to conform to the overall shape of the window panes wherein a first end of the spacer is connected to the opposite end. Folds may be made in the spacer along a crimp line formed in the inner wall to accommodate angular window pane configurations. Folding of the spacer about the crimp line deforms the sidewalls and a fraction of the inner and outer walls inwardly in order to prevent a width increase of any wall which may pro…
