Grilles: A Closer Look at a Traditional Window Element

Grilles, also known as grids or muntins, are common elements of traditional window designs. In this blog, replacement window company Renewal by Andersen® of Memphis takes a closer look at this traditional window element.

Traditional Grilles

Glass set in latticework has been in use for as long as humans have known how to make blown glass. But the grilles as we know them today were derived from Renaissance-era France and were born of necessity rather than by design. During the time, glassmaking technology hasn’t advanced yet. Glassmakers at the time were already making almost-clear glass, but they could only do so in small pieces. Grilles were made to hold these trimmed pieces of glass to a window or door sash.

Modern Replacement Windows

With the advent of sheet glass manufacturing and insulated glass packages, grilles have become more a decorative element than a functional one. Almost every window replacement service company in the country offers replacement windows with a single glass package occupying the window sash. This helps keep the window energy-efficient as well as make it easy to clean and maintain. Grilles can be installed during manufacture using different methods:

  • True Divided Lites — This is the only exception to the rule, as individual panes of glass, or lites, are separated by the grilles, built as part of the framework. This particular style can cost more than typical insulated replacement windows as there are more transitions between glass and frame or grill.

  • Simulated Divided Lites — This style features a single large glass pane with the grilles installed on top of the glass. On double-pane glass, the space between interior and exterior surfaces is maintained. Unlike other similar options, simulated divided lites are non-removable.

  • Simulated Divided Lites With Spacers — This is the same as simulated divided lites, but with spacers sandwiched between the grilles. In addition to creating a look closer to true divided lites, it also helps improve window strength.

  • Between-the-Glass — The grilles are installed between the interior and exterior glass surfaces. This makes the windows easier to clean, but it can look obviously simulated when viewed from the outside.

  • Removable External Grilles — Another style that’s easy to clean. The grilles are attached to the window’s exterior surface using magnets or clips.

Renewal by Andersen offers grille options in the following configurations: full divided lites (simulated divided lites with spacers), between-the-glass, and interior wood grilles, which are removable grilles but attached to the interior side. We offer popular grille styles such as Colonial, Farmhouse and Prairie.

"Absolutely wonderful experience working with renewal. They kept my wife and I up to date all throughout the process from the initial sales pitch to installation. They were courteous and professional throughout. The installation of 8 windows was completed in one day and the product is fantastic. Immediate difference felt inside the home and its much quieter now too. My wife and I are thrilled at our purchase. The windows are a bit pricey but worth every single penny. Wonderful product from a wonderful company. Will definitely be using them in the future to install the rest of the windows in our home."

"When I say, superior service I mean just that!! From start to finish I was pleased!! Step 1, Scheduled appointment at the Home show… easy. Step 2, phone call to confirm appointment the next week….easy. Step 3, in home consultation with Keith Billingsley…..Amazing!!!! Step 4, call and cancel all other Window companies and let them know you have chosen the Best company, Anderson Windows!!! My Windows took a couple of months to come which was not a problem. Oooohhh but when installing day came ( a week early) I was lost for words. The installation team was A1 with professionalism and cleanliness!! They didn’t leave a scrap of trash on my property. It was cleaned up both days. I had Ed Tutton and crew. I had a million questions and they answered every one of them and made me feel so assured with the process. A couple of my Windows had wood rotted. They took care of it and fixed it better than when the house was built!!! Two of my Windows came in broken, it was addressed and shown to us and reorder in the same day!! They will be installed later. The Windows are so beautiful I stood in my master bedroom Windows for almost 3 hours just looking out. I hate Window grates…. I have solid glass Windows now❤️❤️! I wish I would have ordered my new front doors from Anderson Windows. So if you are looking to get new Windows you must go with Anderson Windows!!!"
