Casement Window: 7 Things You Need to Know before Decoration

There are many types of windows. Learning about all of them can be a daunting assignment. Have you ever heard about ‘casement windows’? This post is for you: it discusses everything you need to know about casement windows.

What is a Casement Window?

The appearance and character of a building are greatly influenced by the number and type of windows. Windows are designed to serve both aesthetic and functional purposes. The functional purposes include among others: lighting, air ventilation and security. When well-chosen, designed, and positioned, windows increase the aesthetic appeal of your home.

Casement Window

Often referred to as Crank Windows, Casement windows are a highly versatile type of window that open outward when you wind a crank. They are permanently mounted into a space and do not hang in a window frame by ropes. Basically, casement windows are like doors with the only difference being that they open with a crank instead of a knob.

It is important to note that modern designs of casement windows have been introduced that open inward.

Casement Windows are ideal in hard-to-reach places like above your cabinets and counters. This is because they can be opened by a single hand. They are also amazingly easy to clean.

Casement Windows can be made to fit any height and width.  They are also made from different materials with the popular materials being Aluminum, Wood and White PVC.

Parts of a Casement Window

A casement window, like any other type of window, has different parts. The window frame is made up of the head, jambs, and the sill. It is the outer border of the window that is usually attached to a wall. It can be made from Wood, Aluminum, or PVC.

Parts of a Casement Window

The window frame is usually surrounded by a casing. A casing is the decorative element normally placed between the window frame and the wall into which it has been mounted.

The window sash is the frame that holds the window panes in place. Like the window frame, it can be made from different materials with the popular choices being PVC, Aluminum, and Wood. It has hinges on one side. The hinges enable the sash to open.

The crank handle at the bottom of a casement window enables it to open and close.

The other parts of a casement window are the latches and stay. The stays are the horizontal bars that support the window when it is closed. They prevent the window from shifting the window around. When connected, the latch secures a closed window that it doesn’t open.

The History of Casement Windows

Casement windows became popular in the UK in the 18th century when the stone mullioned window fell out of fashion. The main limitation of stone mullioned windows was that they weren’t very adaptable and couldn’t open to let in light.

History of Casement Windows

Initial casement windows were made from Iron with lead latticing but with time they began to be constructed purely from timber. Glazing bars also replaced the lead strips that hold the pieces of glass intact.

Different Types of Casement Windows

Different Types of Casement Windows

According to this guide, casement windows can be grouped into three categories as below:

Single Frame

Single Frame Casement Windows

These are the most commonly installed casement windows. They only have one frame. The glass panels inside the frame are separated by wooden strips.  Single frame casement windows can be mounted to open either inwards or outwards.

Double Frame

Double Frame Casement Windows

This type of casement window is sometimes referred to as French windows. These are two windows hinged on the sides that swing out and meet in the middle.

Push – Out

Push - Out Casement Windows

This type of casement windows come in both single and double styles.  Push-out casement windows are operated by a handle and not a crank.

Casement Vs Awning Windows

Casement and Awning windows can be a great addition to your home. They are a popular choice for many home owners here in the US.  Understanding the difference between these two types of windows will help you make a well-informed decision.

Casement Vs Awning Windows

Collectively, casement and awning windows are referred to as cracking windows. This is because they are both opened using a cranking mechanism. They easily glide open by turning an easy-to-reach fold-down handle These two types of windows are quite similar with only a minor difference between them.

Casement and Awning Windows have two distinct differences.  Casement windows have hinges in the side and open going out, either to the right or to the left. They are designed for openings in which the height is greater than the width. On the other side, awning windows are hinged at the top.  They are suited for openings where the width is greater than the width.

With these types of windows, you enjoy maximum light and ventilation as they open outward fully. They are suitable for places where maximum light is required such as the bathroom and the kitchen. If you desire unobstructed views in the living room, these two types will suit you.

To install this style of windows, you will have to provide a lot of free space around them. This free space allows them to open outward fully.

Casement Vs Sliding Windows

Both Casement and Sliding windows are a popular choice as replacement windows. They can both improve the appearance of your home and make it more energy-efficient.

Casement Vs Sliding Windows

There are several differences between the two types of windows. Sliding windows are used in openings in which the width is greater than the height. Conversely, casement windows are suited for openings in which the height is greater than the width i.e. tall and narrow openings. Whereas sliding windows open sideways, casement windows open outwards.

In terms of air ventilation, casement windows perform better than sliding windows. This is because they open completely allowing air to pass through the entire opening. Sliding windows allow only for half of the opening to open providing less ventilation.

Another difference between these two types exists in their energy efficiency performance. Casement windows are more energy efficiency than sliding windows for the simple reason that they are inflexible by design. The seal of a sliding window is designed to be flexible so that the window can be opened and closed with ease.

The Disadvantages of casement windows are:

  • Casement windows are not quite characterful as their sash window counterparts.
  • Casement windows are also limited in size. Because casement windows open outwards their frames need to be able to support the weight of the window. This is limiting to the window as far as its dimension and weight are concerned.
