Garage Door Window Terminology

When it comes to garage door windows, there may be a lot of terms you’re unfamiliar with. Here, we list out common phrases with their definitions so you can fully understand the components of your garage door windows.

  • Garage Door Windows — Large areas of glass in a door that may or may not have inserts/grilles.
  • Garage Door Lites — Smaller areas of glass in a single window area that are defined by inserts/grilles.
  • Garage Door Window Inserts or Grilles — Divides a large pane of glass into smaller lites that mimic older, historical window unit styles.
  • True Divided Lite (TDL) Windows — Each piece of glass is separated and has its own structural frame and interior stop. If one lite breaks, only the broken lite will need to be replaced. Because of the number of actual windows, this is a more expensive option.
  • Simulated Divided Lite (SDL) Windows — A large, single pane of glass with decorative, exterior inserts/grilles that visually divide the large area of glass into smaller lites, giving the illusion of True Divided Lites. If there is breakage, the entire piece of window glass will need to be replaced.

Garage Door Window FAQs

What’s the Benefit of Having Garage Door Windows?

Window configurations can be worked into garage door designs to mimic and enhance the existing architecture of your home. The benefits don’t stop there, though! Garage door windows can be customized to suit a home’s unique style. They allow natural light to enter garages, helping to decrease energy bills and increase aesthetic appeal. Plus, you can choose between TDL and SDL windows to meet the needs of your budget.

Are Garage Door Windows Safe?

Yes! There are multiple options that you can choose to maximize garage safety and security. If you’re worried about visibility, textured and opaque specialty glass styles prevent anyone from seeing your garage interior, while still letting natural light in. If you’re worried about durability or potential break-ins, tempered and laminated specialty glass prevent breakage.

Can You Replace Garage Door Windows?

Our garage doors have incorporated stops that hold the window glass in place. These stops can be removed from the back of the door to replace broken glass or upgrade to a specialty glass.

Replacing or adding window inserts/grilles to a door can be complex and will depend on how the door was originally made. If your original garage door design incorporated inserts/grilles, they can be replaced with new ones. If the door was designed without inserts/grilles, it may not be possible to add any to it. You can consult with your door manufacturer to see if it’s a possibility for your door.
