Casement and awning windows are two very popular window replacement options. Both window styles are quite similar in structure, but they are definitely not the same. Understanding the differences between the two windows can help you make the right choice if you are in the market for replacement windows.

Let’s look at the differences between casement and awning windows:

What are Casement Windows?

Casement windows are hinged at the sides, either the left or right-hand side of the window frame. They normally open outward with the assistance of a cranking mechanism to allow for full ventilation. Casement windows are best suited for walls in which the height is greater than the width. 

Casement windows are available in a wide range of configurations, finishes, dimensions, and materials.

These windows offer unobstructed views of the outdoors, provide ample ventilation, are easy to use, and offer ultimate versatility. 

What are Awning Windows?  

Unlike casement windows which are hinged at the side, awning windows are hinged at or near the top of the frame rather than on the side. These windows tilt open at the bottom, allowing for maximum ventilation. Awning windows use a simple crank mechanism whereby you crank a handle to push the bottom of the sash out.

Awning windows are best suited for walls where the width is greater than the height. These windows offer a wide range of advantages, including unobstructed views, extraordinary functionality, and versatility. 

However, there should be adequate space on the exterior to allow awning windows to tilt outwards. They may not be an ideal choice if you have planted trees near your home or where there’s not enough space to allow the windows to tilt outwards.

The differences between casement windows and awning windows boil down to five aspects—hinge system, space configuration, opening space, ease of cleaning, and orientation. 

As we’ve already highlighted, casement windows are hinged at the side, while awning windows are hinged at the top. Your preferred hinge system will determine your choice between the two options. 

In terms of space configuration, casement windows are ideal for walls with a greater height than the width, while awning windows are ideal for walls with a greater width than the height. 

These two window styles also differ in terms of the space they need to open fully. Casement windows require more space to open fully, while awning windows require slightly less space.

When it comes to orientation, casement windows are oriented vertically with hinges on either the right side or left side of the window frame. On the other hand, awning windows are oriented horizontally with hinges at the top of the window frame. Casement windows open either to the left or the right, depending on the side where the hinges are located. Awning windows open from the bottom.

These are the key differences between casement and awning windows. We hope this guide helps you make the best choice if you are in the market for replacement windows.
