Benefits Of Awning Windows


Awning windows are similar to casement windows, with one major difference. While casement windows are hinged on the side, awning windows are hinged at the top of the window frame. Since awning windows can be open while it’s raining without letting water into to your home, they can boost ventilation even during rainy weather.


Awning windows are very difficult to break into because locks and keepers are embedded within the window frame. This makes it virtually impossible to break into without breaking glass. Additionally, awning windows have two locks (one on each side) instead of one, which further increases security.

Unobstructed Views

Awning windows provide virtually unobstructed views to the outdoors. Therefore homeowners can have a greater sense of openness and connection with the natural environment.


Some homeowners may purchase a traditional window style, such as double-hung windows, for entire home, but will use awning windows in places more difficult to reach. An awning window is an ideal window to place above cabinets, counter tops and sinks, because the crank-out handle mechanism makes it easier to open. Some people choose awning windows for bathrooms as well.

Streamlined Look

Awning windows offer streamlined look. This simple design is an appealing choice for wide variety of homes in Connecticut ranging from: modern, craftsman to bungalow and other home styles.

Protection from the elements

Like casement windows, awning windows are some of the most energy efficient and airtight windows, therefore, they provide exceptional protection from the elements during inclement weather. Moreover, due to their ingenious design of top-hinged sash, awning windows can be open while it’s raining without letting water into the house.
