What Are Casement Windows?

A casement window is typically attached to the frame using hinges (one or more hinges) and opens to the outside in either direction. The casement window can be configured in many ways. The openers can be side hung, top, or even fixed. However, the common configuration of a casement window is the side hung, which is easier for most people to open. 

A less common configuration is an awning casement window, which comes with hinges at the top. It is a preferred design, especially in rainy regions as they block the rain. Another configuration is the bottom-hung casement window, commonly installed in basements.

If you were looking to buy a replacement window in Ottawa that is practical, versatile, and convenient, a casement window would be the best option for you. These windows can be custom-designed to fit any window opening and are available in various materials and finishes, from steel and fibreglass to wood.

Types of Casement Windows

There is a variety of casement windows available from Buildmart, a local Ottawa business with more than 15 years of experience in the industry. Some of the common ones include the following: 

  • Single casement window – as the name suggests, its design comes with a single frame though it might have several panels of varying sizes – this depends on the window opening size. Similarly, the panels could have varying sizes.
  • Fixed casement window – commonly referred to as a picture window by most homeowners, it is unique from other window configurations since it is inoperable. Because they are not openable, they do not provide enough ventilation, and for this reason, they are paired with operable windows styles such as single or double-hung windows.
  • Double casement windows – they are also popularly known as French casement windows by some homeowners as take after the popular French doors. They are the best option to buy if you want to catch an unobstructed view of the outside. They offer that ideally as they lack stile in the center of the frame.

All casement windows open outward. Since they use hinges to operate, they are effortless to close and open. Whether you would choose casement windows for your home will depend on the shape and size of the window frame, among other things. Flush casement windows, for instance, create a very slim profile on the façade of your structure and are the best option if you want to save space.

Besides the configuration of the casement windows, they can also be classified according to the material used to make the window. In this class, we have the following common options:

  • Steel casement windows – these are common window materials normally used in commercial applications. They are preferred because they are cheap, durable, and strong. However, steel casement windows require regular maintenance, and they are not as beautiful as other options such as wood.
  • Wood casement windows – for centuries, builders have used wood to make windows. Wood is preferred for its aesthetic, strength, and durability. Besides, it can be stained or painted in different colours easily. However, wood requires a lot of maintenance to keep its beauty.
  • Aluminum casement windows – for homeowners less interested in beauty and looking for something affordable and easy to maintain, aluminum casement windows come in handy.
  • Vinyl – vinyl casement window is a newcomer in the window manufacturing industry. However, the material has proved to be very competitive in all aspects. It is strong, resistant to fading and warping, durable, and provides a wide of hues to choose from. Besides, it comes at a low cost compared to its counterpart wood or fibreglass.
  • Fibreglass – they are also new to the window industry but very famous among homeowners. They are strong, beautiful (some resemble wood), and durable. However, all these features come at a high cost reflected in their prices, which can be way up north!

Features and Benefits of Casement Windows

If you are considering casement windows for your house in Ottawa, here are the main aspects to pay attention to:

  • Casement windows form a tight seal when closed thanks to the sashes that press tightly against the frame. This helps prevent heat loss, making casement windows highly energy efficient.
  • They are wide and open and close by using a crank mechanism rather than a sliding feature. As a result, you can open the windows wide for ventilation and allow more natural light into the rooms. This enhances ventilation and makes your home naturally lit.
  • Casement windows are easy to operate – unlike the traditional casement windows, modern ones come with a crank handle that makes operating the window effortless.
  • The frame of casement windows lacks a central rail, a feature that allows it to offer an unobstructed view.
  • Casement windows are fitted with a lever that locks the windows in many points, making it secure and hard to force entry by intruders.
  • These windows are easy to clean since you can open them wide and access every part when cleaning.

What makes a casement window unique?


Casement windows are different from others because of their high-energy efficiency. The windowpane presses tightly against the outer frame creating an airtight seal. That keeps warm air in and cold air out.

What differentiates a casement window from an awning window?


Awning windows are designed to be fitted in openings with greater widths than height. Both styles of windows open outward and offer great ventilation and maximum natural light.
