A window contains a decorative grille bar assembly which is mounted atop a single glazing panel to simulate the presence of separate window panes. The grille bar assembly comprises a plurality of hollow metal extrusions which are connected to one another, and to the window frame, by plastic inserts which are press-fit in hollow ends of the grille bars. The inserts are connected to the grille bars and to the window frame by tongue-and-recess connections.
