An insulated window panel assembly for use in window and door assemblies hav- ing 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 produce a point with the adjoining window pane.
