Window Grilles Provide Homes Unique, Historic Touches

Published on

Spring is here, with the promise of pleasant temperatures on shiny and sun-filled days. It’s a smart time to think about grilles. Not the grills that cook tasty summer meals, but the grilles that can refresh the look of your home’s windows.

Window grilles are decorative horizontal and/or vertical bars that divide larger panes of glass into patterns. They are often used as a design throwback to when window glass could not be produced in the large sheets seen today.

Back then, glass was fragile and large pieces were almost impossible to move without breaking. The process was to create multiple small pieces of glass connected together by window grilles.

Even though today’s technology has made it possible to create windows without needing grilles, the design of windows with grilles has maintained popularity with people who want a traditional or historic look for their architecture.

Look at any Victorian, Cape Cod or Colonial style home, for example, to see familiar home architectures that might not look “right” without windows that have grilles.

History and technology meet midway when it comes to current window grilles. You can see a variety of options in replacement windows for grilles that not only maintain a sense of timeless style, while featuring current conveniences.

From grilles that provide the look of separated window panes to grilles that can be removed in order to make cleaning and maintaining window glass time-saving, there are window grille options that suit almost any homeowner’s needs.

Here are some common grille types offered by Pella of Hunt Valley, as well as conveniences that come with each:

  • Integral Light Technology (ILT) Grilles

    These grilles are for those who desire a window grille that gives a realistic look of individual windowpanes without the expense of customizing a window. Depending on the type of window, either wood, fiberglass or vinyl grilles are permanently placed to the inside and outside of the window glass.

    Some windows have a nonglare foam spacer that then is placed between the grilles to create a shadow that gives the impression of individual glass panes — making an authentic look of true divided-light windows.

    ILT grilles are a great option for homeowners looking for windows that are an authentic complementary match for their traditional or historic architecture. These grilles can be made in unfinished or prefinished stained wood, or painted and primed fiberglass or vinyl.

  • Simulated Divided-Light Grilles (SDL)

    SDL grilles offer the same approach as ILT grilles, with grilles bonded to the inside and outside of the glass. Unlike ILT grilles, SDL grilles typically do not provide a spacer between the grille and the glass.

  • Removable Roomside Wood Grilles

    Unlike other divided-light grilles, removable grilles are placed to the interior side of windows with latches. This allows the grilles to be uninstalled and makes cleaning the glass more convenient, while still providing the look of divided windowpanes in the window. Like divided-light grilles that are adhered to the window, though, removable grilles can be created in unfinished wood, prefinished stained wood or painted and primed.

  • Between-The-Glass Grilles

    As opposed to divided-light grilles that are typically affixed on both sides of the glass or removable grilles that are secured to the roomside of the glass, between-the-glass grilles are, as the name suggests, installed between the panes of insulating glass in double- or triple-paned windows.

    The benefit of these grilles is that homeowners get the design of divided windowpanes while still having a smooth glass surface that’s simple to clean.

    Between-the-glass grilles can be made to be removable. In windows including this style of grille, the space between the panes of glass, sometimes referred to as a swinging panel, can be opened in order to remove the grille for cleaning, or when cleaning the panes of glass.
