Casement Windows UK
Casement windows are hinged at the side or top and open outward with a crank. They offer great ventilation and clear views. In this article, learn about the types, costs, and benefits of what is a casement window.
What Are Casement Windows?
Casement windows are a type of window that is hinged at the side or top, allowing them to open outward like doors. This design not only maximises ventilation by capturing side breezes but also provides an unobstructed view and abundant natural light.
Most modern casement windows use a crank handle mechanism, which operates a geared system to facilitate easy opening and closing. This feature makes them incredibly user-friendly, especially for hard-to-reach areas. French casement windows are another elegant option that offers similar benefits.
Security is another significant advantage of casement windows. They often come with lockable handles and are resistant to forced entry, offering peace of mind to homeowners. Their design ensures a tight seal when closed, which enhances their thermal efficiency and helps reduce energy costs.
Whether you are looking for a window that provides excellent airflow, security, or aesthetic appeal, casement windows tick all the boxes.
Types of Casement Windows
Casement windows come in various styles to suit different architectural needs and personal preferences. The main types include side-hinged casement windows, top-hung casement windows (also known as awning windows), and fixed casement windows.
Each type has unique features and benefits that make it suitable for different applications.
Side-Hinged Casement Windows
Side-hinged casement windows are hinged to the side of the frame and can open either inwards or outwards. This design allows for superior airflow and ventilation, making them ideal for living areas.
Single casement windows are a common type, featuring a standard-sized frame and a simple design. Double casement windows, on the other hand, have two sashes that open in the centre, providing unobstructed views and enhanced ventilation.
Top-Hung Casement Windows (Awning Windows)
Top-hung casement windows, also known as awning windows, are hinged at the top and open outward from the bottom. This design is particularly beneficial in wet climates, as it allows for ventilation while preventing rain from entering the room.
Awning windows are often used in bathrooms and kitchens where ventilation is crucial, but protection from the elements is equally important. An awning window provides a great solution for these needs.
Fixed Casement Windows
Fixed traditional casement windows do not open but are designed to match the aesthetic of other casement window styles. They provide unobstructed views and let in ample natural light, making them perfect for spaces where ventilation is not a priority but visual openness is desired.
Their design often includes mock sashes to create a cohesive look with operable casement windows.
Comparison with Other Window Types
Casement windows offer unique benefits that set them apart from other window types. Their ability to open fully allows for maximum ventilation and an unobstructed view. Additionally, they are designed to withstand harsh weather conditions, making them a reliable choice for storm-proofing.
However, it’s essential to understand how they compare with other popular window types like sash and sliding windows to make an informed decision.
Casement vs Sash Windows
Casement windows and sash windows differ significantly in their operation and benefits. While casement windows open outwards on a hinge, sash windows slide vertically. Casement windows offer a more modern look and are easier to clean from both sides due to their swing-open design. Sash windows may be more susceptible to draughts and weather damage. This is due to their sliding mechanism, making them less waterproof compared to other window types.
However, traditional sash windows carry historical significance and a traditional aesthetic that many homeowners find appealing.
Casement vs Sliding Windows
Sliding windows glide horizontally along a track, offering a different operational mechanism compared to casement windows, in which the window swings open on hinges. Casement windows allow for maximum ventilation as they can open fully, whereas sliding windows provide easy access and are less likely to obstruct walkways.
Each has its unique advantages, making them suitable for different applications and preferences.
Material Options for Casement Windows
The material of the window frame plays a crucial role in the performance and aesthetics of casement windows. Common materials are uPVC, aluminium, and timber. Each of these options offers distinct advantages. The choice of material can affect the window’s durability, insulation, maintenance requirements, and overall cost.
uPVC Casement Windows
uPVC casement windows are recognised for being cost-effective. They also require minimal upkeep. They offer excellent energy efficiency, making them a popular choice among homeowners. The cost of uPVC casement windows typically ranges from £372 to £961, including installation.
Cleaning is straightforward, requiring only a damp, non-abrasive cloth to maintain their appearance.
Aluminium Casement Windows
Aluminium casement windows are praised for their strength and durability. They are resistant to warping and often come with longer warranties. However, if not maintained properly, the hinges can rust, posing a security risk.
The price range for aluminium casement windows is between £744 and £1,147.
Timber Casement Windows
Timber casement windows offer a classic aesthetic that complements both traditional and contemporary architecture. They are generally more expensive, with prices ranging from £1,147 to £1,829.
Advancements in timber processing have improved their durability and reduced maintenance requirements, although regular inspections and treatments are still necessary.
Glazing Choices for Casement Windows
The choice of glazing significantly impacts the performance of casement windows. There are several options available, including double glazing, triple glazing, and low-E glass. Each of these choices provides varying levels of insulation, energy efficiency, and noise reduction.
Proper glazing ensures that casement windows are highly energy-efficient and cost-effective in the long run.
Double Glazing
Double glazing involves two panes of glass separated by a spacer, providing enhanced insulation and noise reduction. Casement windows with double glazing are designed to seal tightly, improving energy efficiency and helping regulate indoor temperatures. They can keep spaces warmer in winter and cooler in summer, contributing to energy savings.
However, blown double-glazing can compromise their effectiveness, so it’s essential to ensure proper installation and maintenance.
Triple Glazing
Triple glazing offers superior energy efficiency, noise reduction, and security compared to double glazing. It involves three glass panes, which can significantly reduce energy costs by up to a third.
Casement windows with triple glazing have an excellent U-Value of 0.9 W/m2K, indicating top-tier thermal performance.
Pros and Cons of Casement Windows
Casement windows offer numerous benefits, but they also come with some drawbacks. Understanding both the pros and cons can help homeowners make an informed decision about whether these windows are the right choice for their homes.
Advantages
One of the most significant advantages of casement windows is their ability to provide excellent airflow and ventilation. They catch outside air and funnel it inside, making them ideal for areas that need maximum ventilation.
Casement windows also create an airtight seal when closed, which enhances their energy efficiency and makes them highly energy-efficient options. Additionally, their design contributes to home security by making it harder for break-ins.
Disadvantages
Despite their many benefits, casement windows also have some disadvantages. They require more open space to operate effectively, which can be a limitation in smaller areas. Aluminium casement windows can be prone to corrosion, and their mechanical parts may sag over time.
Wooden flush casement windows require periodic maintenance, such as painting or staining, to protect the wood and keep the seals intact. Additionally, their design can make them vulnerable to strong winds and rain, which may cause damage or water entry.
Cost Considerations for Casement Windows
The cost of casement windows can vary widely depending on the type, size, and material. uPVC casement windows are the most affordable, with prices ranging from £372 to £961, while timber casement windows are the most expensive, starting around £1,147 and going up to £1,829.
Labour and installation costs can also add significantly to the total expense, often accounting for 40-60% of the total cost. It’s essential to consider these factors when budgeting for new casement windows.
Customisation Options
One of the appealing aspects of casement windows is the wide range of customisation options available. Homeowners can choose from various materials, colours, and hardware to match their home’s aesthetic. Grille patterns, dimensions, and flush designs can also be tailored to create a cohesive look.
This flexibility allows for creative window designs that enhance both the functionality and appearance of the home.
Safety and Weatherproofing
Casement windows are designed to be weatherproof, ensuring they can withstand harsh weather conditions. Top-hung casement windows, in particular, prevent rain from entering the room, making them ideal for wet climates. These windows also feature locks embedded within the frame, enhancing security against break-ins.
The combination of weatherproofing and safety features ensures that casement windows meet building regulations and provide peace of mind for homeowners.
Casement Windows UK – In Summary
