Once required to create larger windows out of relatively small panes of glass, divided lights are now an architectural detail of windows and doorglass that adds charm and authenticity to a home. Many popular residential styles use distinctive divided lights as an essential element of the overall look and feel.
Today, many window and doorglass manufacturers achieve a divided light look with a single piece of glass or an insulated glass unit rather than the multiple used in a true divided light. This has many benefits, including better energy efficiency and a lower price point. We’ll go over three of those approaches that are offered by ODL and compare a few key factors.
One of the main benefits that true divided lights provide is a sense of historic charm. Many older houses were built using true divided lights, which give a distinct look due to each of the individual panes of glass reflecting light a little differently. Because each pane is sealed to the grille individually, older true divided lights can get drafty, decreasing the energy efficiency of the home. Modern home building projects can still emulate the historic appeal of true divided lights with the added benefits of enhanced glass manufacturing capabilities.
From here on out, we will be discussing how we create divided light looks for doorglass. Window manufacturers who have divided light options may use slightly different terminology or methods to create a divided light look.
Instead of using multiple, separate insulated glass units (IGUs), simulated divided lights (SDLs) feature a single IGU with both internal grilles between two panes of tempered safety glass and external grilles to closely mimic the look of a TDL. The outer grilles, which are molded to the doorglass frame, cover the mill finish internal grilles to create the illusion that each section of the divided light is separate from the next.
The result is a similar luxurious, historic feel to TDLs without the labor and associated cost involved in piecing multiple panes of glass together. SDLs are lower-maintenance than TDLs, and because there is only a single insulated glass unit being used, SDLs are more energy-efficient than classic divided lights and won’t degrade over time. We offer three frame options for SDLs: our traditional profiled Evolve® frame, the Craftsman frame, and the ZEEL® frame in the 22” x 17” Craftsman size.
We offer hundreds of configurations of GBGs, including Traditional, Arts & Crafts, and Prairie styles to match any home. We also offer three bar widths, two flat and one contoured, so it’s easy to find the perfect fit. GBGs are typically lower priced than SDLs, and far more cost effective than TDLs.
The simplified construction of an external grille allows us to offer unique sizes and configurations, including diamonds, round tops, and the iconic gothic light. We offer external grilles in Clear and Low-E glass options.
At ODL, we offer divided light doorglass for any home and project budget.
