There are many options to consider when planning out a window replacement project, from selecting the style of windows to the energy efficiency options, it is easy to get crossed up at times. If you are looking at window styles and are considering either awning windows or casement windows, you may be curious about their differences and where and when it is best to use each style.
Below we outline the significant difference between these two popular window replacement styles.
Let’s begin by learning about each window style first.
What are Awning Windows?
Like their name suggests, awning windows open in the same fashion as an awning. They open outward and upward to allow adequate ventilation and natural light into your home. They are operated by a crank and thanks to their tight locking mechanism, offer a high level of energy efficiency when closed. Because of their design, you are able to leave awning windows open while it is raining to allow fresh air into your home without the fear of water getting in.
What are Casement Windows?
Casement windows also incorporate a crank mechanism that allows the window to open outward and to either the left or the right. They are arguably one of the most popular window styles on the market, and are commonly used during window replacement projects. They allow for maximum natural light and adequate ventilation into any home. As well, they offer clear, unobstructed views of the outdoors as there is no frame going through the middle.
Awning vs. Casement Windows: What’s the Difference?
Awning windows and casement windows have several similarities, namely that they both use a crank mechanism to allow the window to open outward and they both offer unobstructed views. When it comes to differences there are several significant ones, such as:
Both awning and casement windows are usually rectangular, but they are structured differently. Awning windows usually have a longer width than height, while casement windows tend to have a longer height than width.
Awning windows are hinged on the top of the window frame, while casement windows are hinged on either the right or left side of the window frame. As a result, awning windows open outward and horizontally while casement windows open sideways vertically.
Both awning and casement windows are low maintenance, but cleaning awning windows is more difficult as the sash opens upward. In many cases cleaning casement windows does not require you going outside your home or the need of ladders.
Awning windows are best suited for rooms where there is a need for constant or regular ventilation, where the windows can be left open without making the house vulnerable to water damage when it rains. As a result, awning windows are suitable for bathrooms and kitchens.
It is crucial to note that there is a limit to how large both casement and awning windows can be. However, awning windows are usually the smaller of the two because they are hinged on the top of the window frame. Awning windows will undoubtedly be too heavy for the hinges if they are used for oversized window openings.
