What is a Window Grill?

A window grill divides a standard window pane into different sections giving the window a decorative pattern by using vertical or horizontal bars.  In the past, smaller window sections helped to structurally distribute the weight of large window panes since window panes were very fragile and larger panes of glass would break easily.  Now in modern times, window grills are mostly used for aesthetic detail and to add architectural interest.  

Window manufacturers offer several decorative design options and different grill placement locations for window grills.  Grilles can come between the glass, as simulated wood on the exterior of the glass or inside the house as true wood or simulated wood.Typically your options are:

  • Simulated Divided Lites (SDL) 
  • Grilles Between the Glass
  • True Divided Lites (TDL)

Your home designer should be able to help you add the best window grill options for the style of house you desire.
