What is a Grille?

By effectively dividing a large glass sheet into smaller sections, grilles help to manage and distribute the weight of the glass, making large window frames a possibility for homes and other buildings. However, as technological advancement makes manufacturing large glass sheet and strong window frames a feasible option, the use of grilles have been shifted from utility to aesthetics. Today, they are widely coveted for their creative appeal and aesthetic contribution to a home’s architectural design.

Marvin Window Grille Options


We offer unmatched options that seek to draw out the beauty and ambiance of your home. Our two major grille options include: Grilles-between-the-Glass (GBGs) and Simulated Divided Lite (SDL). The main difference between the two is that the former has bars located between the panes of insulating glass, while the latter has bars permanently adhered to the outside surfaces of the glass with a spacer bar between the panes of glass:

  • Grilles-between-the-Glass (GBGs): Bars facing the interior are available in Stone White, Sierra, Satin Taupe and Bronze.  We offer 13 gorgeous colors for your exterior so you could creatively mix-and-match the interior and exterior hues in any way you like.
  • Simulated Divided Lite (SDL): Exterior divided lite bars are made of the same tough Ultrex fiberglass used on all Infinity exteriors. Interior bars are available in Stone White, Sierra or stainable EverWood to match your existing woodwork.

For homeowners who desire to take their customization to the next level, we offer a generous selection of divided lite patterns for you to create a unique look for your Infinity replacement windows. We offer rectangular, cottage, prairie styles, and more. Combine your beautiful patterns with our stunning stain selections and you will successfully transform a traditional window into a masterpiece endowed with creativity, interest, and charm.
