Each lite is a separate glass unit, whether single, double, or triple pane. The individual glass units are glazed between dividing muntin bars, creating an authentic, traditional appearance.

Grilles Between the Glass

The grille between the glass is permanently sealed between two panes of insulating glass. Because they are located between two panes of glass, the surface of the window remains smooth, which makes it easier to clean.


Simulated Divided Light offers grilles permanently applied on the exterior of each glass pane, with a spacer in between the panes of glass. This design adds depth and dimension to the window or door, enhancing its visual appeal.

About grille styles

Full Divided Light: Embracing Tradition

True Divided Light, also known as Full Divided Light, is a window construction style where each lite is a separate glass unit, whether single, double, or triple pane. The individual glass units are glazed between dividing muntin bars, creating an authentic, traditional appearance. Although this construction method is somewhat more expensive compared to other options, it offers the benefit of easier maintenance. In the event of glass breakage, only the affected lites need to be replaced, rather than the entire window glass. True Divided Light windows add a classic, timeless charm to any home or building. However, one limitation of True Divided Light is that the muntins need to be wider to cover the ends of the glass units. This can slightly affect the overall appearance of the window, as the muntins may be more prominent compared to other divided light options



Simulated Divided Light: Modern Versatility with Classic Appeal

Simulated divided light windows offer a compromise between traditional aesthetics and modern convenience. Unlike full divided light windows, which feature separate panes of glass divided by physical muntins, simulated divided light windows utilize a single large pane of glass with muntin bars applied to the surface, with a spacer placed between the panes to simulate the appearance of individual glass units. This configuration gives the illusion of separate pieces while maintaining the benefits of a single, uninterrupted pane. The spacer between the glass not only enhances the visual depth and authenticity of the divided light appearance but also improves the window’s energy efficiency by reducing heat transfer. This design approach allows homeowners to enjoy the classic look of divided light windows without sacrificing thermal performance or ease of maintenance. Simulated divided light windows are particularly popular in contemporary homes seeking to evoke a sense of timeless elegance while embracing modern functionality.



Grilles Between Glass: Seamless Integration

For those seeking a sleek and minimalist aesthetic, grilles between glass offer a seamless solution. In this design, muntin bars are encapsulated within the insulated glass unit, eliminating the need for individual panes or surface-mounted grilles. The result is a clean, unobstructed view with subtle grid lines that add visual interest without overpowering the space.

Grilles between glass are prized for their low-maintenance appeal, as they are easy to clean and less susceptible to damage or wear compared to traditional muntin configurations. This makes them an excellent choice for contemporary homes, where clean lines and streamlined design are paramount.
