Grille Types

Options for the look of divided-light windowpanes

Grilles are bars that divide window glass into smaller decorative windowpanes. Historically, true-divided-light windows were made up of individually glazed panes of glass within the grilles — a very inefficient design that’s prone to drafts. Modern grille options give you the look of divided light but are more energy efficient. Some make the glass easier to clean, too.

Integral Light Technology^® (ILT) grilles

Grilles are permanently bonded to the inside and outside of your window glass with a nonglare foam spacer in between to cast a realistic shadow like individual windowpanes would. Creates the most authentic look of true-divided-light windows.

Best use: When you want to be authentic to your home’s traditional or historic design.

Simulated-Divided-Light grilles

Grilles are permanently bonded to the inside and outside of your window glass. There is no spacer between the grilles.

Best use: When you want to be authentic to your home’s traditional or historic design.

Grilles-between-the-glass
