Casement Window Parts: Everything You Need to Know About the Various Parts of a Casement Window

When choosing windows for a building, there are numerous factors to consider. Safety, noise reduction, and energy efficiency are just some of the functions you need to consider when choosing your windows.

Casement windows are one of the most popular types of windows, but there are other options as well. After choosing the type of window, you can choose from a number of finishes, hardware, and decorative features.

To better understand the different selections you might need to make, here’s how you can learn more about various casement window parts.

Casement Window Parts

The sash of a window is the portion of the window that holds and secures the glass. Typically, the sash can be opened with the assistance of a casement operator. Typically, casement windows have hinges on the side, although occasionally they are positioned on the top. This type of window is known as an awning window. Window sashes are essential to the window’s structure. If a sash is not constructed or fitted properly, it may distort and warp with time, resulting in improperly sealed windows that may leak or stop locking properly, which may compromise your home’s energy efficiency and security.

Locking Handle/Locking Cam

The locking handle and locking cam serve to secure the window sash. Typically, there is only one locking handle towards the bottom of the window, which is connected by a tie bar to a locking came at the top.

Keeper

For casement windows, the locking handle and locking cam attach to the keeper to lock and secure the sash. Typically, the keeper is situated on the side of the movable sash.

Butt Hinge

Butt hinges, often known as piano hinges, are what allow the sashes of casement windows to open outwards. The majority of casement windows have hinges on one side. On occasion, the sash hinges are positioned at the top. This type of window is known as an awning window.

Operator and Operator Handle

The window sash is moved using the casement window operator and operator handles. The handle is attached to the operator and is turned in order to open the window. There are either one arm or two arms on operators. One arm (or the lone arm) slots into a track on the bottom of the window sash and moves down the track while pushing the sash outward in both instances.

The above are some of the most prevalent window components found on casement windows. Each window is unique and may include additional components.

Casement Window Glass

Let’s hone in on the glass portion of the casement window.

What Constitutes an Insulated Glass Unit?

Low Emissivity (Low-E) Coated Window Glass: This clear, exceedingly thin coating helps the window deflect unwanted solar heat, enabling a more efficient cooling of dwellings in hot climates. It also reflects the radiant heat radiated by interior objects (such as an HVAC unit) back into the dwelling. This aids in minimizing heat loss throughout the winter months.

Krypton and Argon Gas Fills: Gas fills are required for the production of insulated glass units. Gases such as krypton or argon are utilized to fill the space between the glass units. As opposed to using air alone, these heavier noble gases are more effective at preventing heat transfer via a window.

Warm-Edge Spacers: These seals insulate the glass unit’s edges and keep the panes of glass firmly separated. Warm-edge spacers are crucial to a window’s ability to maintain its energy efficiency over time.

Casement Window Frames

Casement window frames are the main structure of the window. They provide stability and support to the sashes, as well as a decorative element. The frame is typically made from wood, aluminium, vinyl, or fibreglass.

Wooden Frames: Wooden frames are usually made from pine or cedar and can be stained or painted to match your home’s decor. Wooden frames are strong and durable, but they require regular maintenance to keep them looking their best.

Aluminum Frames: Aluminium frames are lightweight and durable, making them a great choice for casement windows. They are also low-maintenance and can be painted.

Vinyl Frames: Vinyl frames are strong and durable, as well as low-maintenance. They come in a variety of colours and can be painted to match or complement your home’s decor.

Fibreglass Frames: Fibreglass frames offer the ultimate in strength and durability, as well as being low-maintenance. They are also energy efficient and can be painted to enhance or complement your home’s architecture and colour scheme. Fibreglass frames are a premium choice as they offer superior insulation and durability.
