How to Use Transom Windows Effectively

It’s not surprising that many homeowners are unfamiliar with transom windows. These windows are not used with the same frequency as double hung or casement windows. Yet transom windows can make a lot of difference, and even substantial benefits. We’ll share how transom windows can be used effectively.

What Are Transom Windows?

Transoms are the horizontal area at the top of an entry door, and transom windows are the windows installed at the transom area. Unlike awning windows, transom windows are typically non-operable and are installed over front doors rather than bedrooms or basements.

Benefits of Transom Windows

  • Architectural accent – Transom windows serve as accent pieces for entry doors and sometimes in lieu of sidelights if there’s limited horizontal space. It also makes the entry door look much bigger.

  • Improved daylighting – The biggest benefit of having transom replacement windows is the increased amount of natural light it lets in. If you happen to have a dark entryway, transom windows should be a priority project – not only does it brighten up your hallway, it reduces your reliance on electrical lighting, which helps reduce your energy consumption.

  • Better ventilation – Transom windows are non-operable windows similar to picture windows (and our own specialty windows), but you can have transom windows that function like awnings for ventilation, creating a canopy-like vent. This is especially useful if there are no other operable windows near the entry hall.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
