Technical diagram showing SDLs vs GBGs

Traditionally, windows were made up of small pieces of glass separated by wood mullions, creating the familiar checkered pattern that homeowners know-and-love. Today, we have found a way to preserve the character and style of traditional windows while avoiding certain maintenance concerns. Two popular, modern grille options include Grilles Between Glass (GBG) and Simulated Divided Lites (SDL). Which one is right for your window?

GBG

GBG are a non-removable feature built within the glass, making them an attractive zero-maintenance option. They create the luxurious appearance of traditional grilles, while offering easy cleaning for both interior and exterior glass surfaces.

SDL

 SDL are installed directly on the exterior and interior surfaces of the glass (non-removable), boosting your windows curb appeal potential while re-creating the traditional appearance of a true divided lite. Install an optional shadow bar to complete the authentic look.
