Difference Between Simulated Divided Lites & Window Grilles

9/10/2014 2:52:00 PM

If you’re shopping for new or replacement windows, you’ve likely run across the terms “simulated divided lites” and “grilles.”

How Are They Different?

True Divided Lite (TDL) windows have individual panes of glass held together by muntin bars for a look similar to homes built during colonial times. While they look very much like the windows of yesterday, today’s technology makes TDL windows extremely energy efficient with insulated glass or insulated Low eglazing.

Simulated Divided Lite (SDL) windows feature a glass pane with the muntin bar grilles permanently adhered to the interior and exterior surfaces to give it the appearance of a TDL window. An optional narrow spacer bar is available for the insulating airspace between glass panes and grille bars. This design offers modern energy efficiency while replicating the look of TDL construction, where each lite is completely separated by a muntin bar.

Simulated Divided Lites (SDL)

Simulated Divided Lites (SDL) offer the authentic look of True Divided Lites without sacrificing energy efficiency. Interior and exterior bars are permanently adhered to the glass and a narrow spacer bar is positioned within the insulating glass airspace. Unlike True Divided Lites, SDL windows utilize a single pane of insulating glass, decreasing the potential for energy loss. Exterior bars will be finished to match the exterior finish specified. Shown with optional grille between the glass (GBG).

Window Grilles

Window grilles are a decorative pattern on a window or door consisting of horizontal and/or vertical bars that divide the larger sheet of glass into smaller panes. Simulated divided lites, mentioned above, are actually a form of window grille. In addition to simulated divided lites, window grilles can also be found on the exterior surface of the glass or in between the glass.
