As a standalone opening or in combination with other windows, an awning window can be the perfect choice for your home — find out how. 

What is an awning window?

An awning window is horizontally oriented and has hinges at the top, so it opens outward like an old-fashioned garage door. Its sash acts like a canopy when open. Opening is easy thanks to the crank and the option to add automation, so this window can open with the touch of a button. Like all our windows, it can be ordered with an insect screen. Its design, with a seal similar to a refrigerator door, makes it one of our most energy-efficient windows.

Sometimes, outward opening awning windows aren’t ideal next to a patio or walkway but, in this case, they open over a garden bed so don’t take away patio space.

What are the benefits of an awning window?

There’s a lot to love about an awning window, including: 

  • Canopy opening brings in fresh air, even when it’s raining. 
  • Crank makes it easy to open, even in an out-of-the way space. 
  • Horizontal shape suits a number of different spaces, home styles, and more.
  • Energy-efficient design makes it a great choice in any climate! 

Where do awning windows work best?

The shape and opening of an awning window lends it to some unique applications. Depending on where it’s used, it can suit a variety of home styles — though it’s often chosen in more modern homes. Here are a few places where it’s ideally suited.

High on a wall

Anywhere you want light, fresh air, and privacy, an awning window is perfect. Here are a couple ideas on where you could place it:

  • In a bathroom, where you always want the option to bring in fresh air, it can even be opened in the rain. 
  • In a basement, where above-ground space may be limited, it can be placed high on the wall and opened easily with its crank.
  • As a clerestory, or a window placed along the roofline, its horizontal shape fits well, and it can be used to create a modern look.

In a window combination unit

If you’re looking to create a showstopping feature by combining multiple types of windows, the versatile awning plays well with others. Here are a few ideas:

  • Picture and awning windows are often combined to frame big views and bring in fresh air, respectively. You’ll find this classic combo in many modern homes.
  • Above a door (called a transom), awnings have long been used as a way to bring in fresh air, even when the door is closed.
  • Above another window (also called a transom), an awning can expand the opening creating a feeling of spaciousness that’s like the effect created by a floor-to-ceiling window. 

Did you know: This type of window comes in sizes perfect for completing large window configurations. For example, the A-Series Awning Window can be up to 6-feet wide and 4-feet tall. If you’re aiming for clean lines and minimal framing, talk to your builder about ordering windows that are designed to be installed together. This is called joining

While transoms are often fixed windows (meaning they don’t open), they don’t have to be and awnings are a great option when you want to bring in fresh air.

Are awning windows more energy efficient?

Yes! Awning windows (along with casement windows) are some of our most efficient windows. This is due to their single-sash design, which allows fewer opportunities for leaking air. In addition, the hardware actually pulls the sash into the frame for a tight seal. 

You can also make selections to further maximize your awning window’s energy efficiency — here's how:

How do you clean an awning window?

Like all windows, awning windows should be cleaned regularly. This will make the most of your natural light and help maintain your windows over time. 

One thing that can make cleaning awning windows a little bit tricky is that they’re often placed in high locations. If that’s the case in your home, it might be wise to hire a professional window cleaner. If you feel equipped to clean your own windows, here’s what else you should know:

  • Interior cleaning: Cleaning the interior of an awning window is no different than cleaning any other type of window. Get started with our detailed instructions and pro tips about how to clean windows.
  • Exterior cleaning: Some of our windows can be cleaned from inside the home — all our double-hung windows have tilt-wash capabilities, and casements can be cleaned from indoors too. Our awning windows, however, are not designed to be cleaned from the inside. You must go outside to clean their exteriors.

Looking for a replacement awning window?

A great option for replacement is available with the 100 Series Awning Window insert replacement. Insert replacements are windows that can be installed into existing frames that are in good condition — not out of square, no rot, etc. An insert creates minimal disruption allowing you to keep your original frame along with interior and exterior trim, and siding. A contractor can tell you if insert replacement windows will work in your home, and we can help you find an Andersen Certified Contractor in your area.
