Casement windows are undoubtedly a key feature in any property. They impact both the aesthetic appearance and character of a building and, very importantly, fulfil several functions such as security, safety, and of course, impact heavily upon a building’s energy efficiency.
There are many styles of windows available to homeowners, but Casement windows are one of the most popular types nowadays in the UK, according to user experience. This kind of window is undoubtedly the most contemporary and convenient of all window types. They are versatile, coming in a wide range of sizes and colours, efficient, customizable, timeless, and extremely practical.
If you are looking for replacement windows, this is where you have to start. These new windows require low maintenance.
In exchange, they ensure noise reduction due to their multiple glazing and lower energy bills on account of their astonishing performance regarding the reduction of heat loss, another advantage of their glazing. They are an excellent investment due to their incredible performance. So, let’s take a look at their origins, benefits, and the types of properties they are most suitable for.
What is a Casement Window?
Casement windows are attached to a frame by one or more hinges, which allow the window to be opened or closed, a function that makes windows and doors somewhat similar, with double or multiple glazing. A manual or automatic crank, located on the corner of the window, allows the window to be fully opened outwards away from home and closed tightly by an interior latch that must be engaged to secure the window shut entirely.
Due to the possibility of opening a casement window out, you are provided with a full viewing outside the house, a property that also optimizes airflow. As a result, you do not need to keep both windows and doors open when you want to ventilate the room. It also allows the outside of the windows to be cleaned from inside the home when they are fully cranked open.
And suppose you opt for a casement window with friction hinges. In that case, this quality will allow a more painless cleaning process, not to mention that the outside frames will also be easier to reach, and you will finish cleaning faster than you would expect.
Casement Windows Through History
Casement windows were introduced back in the 18th century and quickly became the window styles of choice whenever someone searched for a change. They were used as an alternative for mullioned stone windows, with the term ‘casement’ referring to the part of the window that opened. Casements are usually used either independently or in pairs within a standard frame.
At this time, a big part of glass manufacturing was still in its infancy, and casements commonly featured six small panes joined by glazing bars. Nowadays, the glass industry has evolved, and there is a wide variety of casements available, with double glazing or even multiple glazing.
In Tudor homes, the window style was multi-paned, with panes usually diamond or rectangular and set within timber openings. Whereas in Stuart times, they became taller than they were wide so casements had to be typically divided into four by a single mullion.
They were increasingly constructed from timber and became known as cross casement windows rather than timber casement windows. Timber windows are still standard nowadays as they offer good performance, and they come at affordable prices, with double or multiple glazing, usually being the stock option.
Around the Georgian era, sash windows emerged. They became very popular, replacing many timber casement windows, which began to be used primarily only in cottages. However, the Victorian met an increasing development in glass production. With this came the emergence of larger glass panes, which were then set within timber glazing bars producing casement windows that were far more decorative in design. Their place into the homes of many was yet again secured by design.
During Edwardian times, this type of window once again reverted to being more simple and plain in design.
Upvc windows were later introduced and soon became one of the most required products. Whether it is windows, doors, or window shutters, uPVC became the best of options, outrunning the timber windows, mainly because of its affordable price concerning their performance. Upvc windows are usually double glazed and come in a wide range when it comes to shapes and sizes, but the colour options are somehow limited, being available in a small range.

What Variations of Casement Windows are Commonly Available?
The casement window imparts a contemporary style, and with its clean lines and simple geometry, it works well with modern style homes, being secured by design in many homes over time. This type of window has many different configurations, and these are the most commonly seen:
The Single Frame Casement window is the most recognizable project and comprises one frame with a casement hinged on the side or top.
Double casement windows, sometimes known under the name ‘French Casements,’ comprise two hinged casements. They may meet at the center a bit like French doors or have a fixed casement(s) in between, double or multiple glazing.
Picture casement windows are fixed casement(s) within the frame – they afford good views and allow light into the room, and they are perfect if you are looking for home improvements...
Top hung or ‘awning casement windows’ are hinged at the top, opening outwards to let air in at the sides and bottom. They are perfect for homes located in a wet climate as the window blocks out rain and offers draught-proofing. If you live in a wet environment, you might want to choose a uPVC window with trickle vents that help reduce condensation and maintain a constant humidity level in the room.
A Transom Casement window is a window that can be either opened to let in air or fixed and mounted above a door or window to let in more light.
Windows and doors can also be combined when we want a door with an outside view. Known under the name of windows doors, they are most commonly double glazed with uPVC frames or with a timber window.

What Are The Advantages of Casement Windows?
There are many advantages to having Casement windows installed in your home. These include:
Easy to open and close: They are very easy to open and close. Many people say that they are far more comfortable than pushing a sash up and down as all that is required is to turn the crank and operate the lock. For this reason, Casement windows are recommended as the best of options for the homes of disabled persons or those with limited mobility or strength. Casement windows are ideal for the families of wheelchair users as they can even be opened and closed while seated in a wheelchair – note that assistance may be needed to operate the latch.
They bring the outside in: Since they open on one, two, or more aluminium hinges, Casement windows offer fantastic ventilation opportunities. Providing a fully open window, they project the outside on the inside of your homes. And the open sashes can even catch breezes and bring them into your house for natural air conditioning.
A room with a view: Unlike many other designs, Casement windows offer an unobstructed view, as they swing open like a door and do not require grilles or muntins for support. You get an unobstructed view outside and even more natural light filtering in through your window. As part of an enhanced view, you might choose to install a flanking Casement window on either side of a large picture window, which will provide both a fantastic view and improved ventilation.
Energy savings: Casement windows are well known for being highly energy-efficient because they seal very well and due to their double or multiple glazing. The window sash presses straight onto all four sides of the window frame, creating an airtight seal that prevents air entry and cold spots in your home, offering incredible performance and assures draught-proofing. This feature means that Casement windows do an excellent job of limiting air intrusion into your home and ensuring energy efficiency, lowering the energy bills by saving energy.
Security and safety assured: Our range of Casement windows conform to Part Q requirements for security efficiency. This means that they meet the Building Regulations (England) standard windows to resist physical attack by a burglar by being sufficiently robust and fitted with appropriate hardware. Many Casement windows lock better than other window designs as they utilize a multi-point as part of their locking mechanism. Also, casement windows are child-friendly as the distance they open can be limited to prevent falls.
Suited to a variety of property styles: Casement windows are suited to contemporary properties. One of the many benefits of Casement windows is that they are available in a wide range of types and colours, from uPVC to timber windows, all of them offering excellent performance. The designers and installers made sure that they can be hung in many different ways and are fully customizable. They allow the freedom to choose between many options and features such as other materials and grills, and between any colour you like, or the standard colour. The finished product might surprise you, as well as the many different styles you can choose from.
What Are The Disadvantages of Casement Windows?
More mechanical parts: In comparison to other window designs, Casement windows operate with more mechanical parts. This means that potentially more parts could wear out. If this happens, you may need to call the installers. These windows feature latches, friction hinges, cranks, window locks, and any other parts. This means that more pieces can wear out and break down over time compared to sliders and picture windows. Even if the mechanism on Casement windows doesn’t fail, they can slowly loosen due to time factors so that you get more air seepage into your building.
Cost: Casement windows are typically a bit more expensive. However, size, material, placement, and glazing will all be a part of the coast as well, and we do advise you not to make your final decision about your new windows based on prices alone. Finish analysing all the pros and cons.
Size Limitations: Since Casement windows are mounted, they cannot be very wide. Also, because of their design and styles, Casement windows can’t be too large or too heavy. The opening has to be strong enough to support the window, as the aluminium hinges can only support a certain amount of weight. We strongly recommend you consult an expert for enhancing your project.
Air conditioners can’t be accepted: As Casement windows crank outward, they can’t accept air conditioners, so if this is a requirement for your property, you should revise your options, and we recommend that you chose a standard window that slides up and down that will be able to accommodate an air conditioner more efficiently.
Screens or storm windows can’t be used: Finding a casement window that cranks inward is possible, but it is not a common choice. Therefore, if you plan to use screens or storm windows as part of your home, a casement window is not advisable because it cranks outward, so the opening cannot be obstructed.
Are Casement Windows an Economical Option for Replacement Windows?
Casement windows usually have higher prices than double-hung windows. This can largely be attributed to the more complicated mechanical operations of Casement windows and their better performance. They are, however, a cheaper option than vertical sliding sashes. However, it should be noted that you may find that part of the cost of fitting the Casement windows in place of sash windows is more expensive, so while they are a cheaper option, the window installation is more costly than usual.
