Casement Windows: Types, Materials, Advantages and Disadvantages.

Different Types of Casement Windows for London and Surrey

Casement windows are a kind of window that consists of one or two panels attached to a vertical or horizontal hinge. Typically, casement windows open outward, but there are also tilt-and-turn windows that tilt inward and open inwards.

These windows have been around since medieval times and are the oldest type of window in the UK. They are also popular in millions of UK homes due to their practicality and versatile design.

 

 

When choosing new windows, it's important to be aware of the different types of casement windows.

Single casement windows consist of a single hinged panel within a frame, which typically opens like a door and has a casement fastener. Double casement windows, on the other hand, open from the center outwards on either side of a central vertical post, or "mullion." French casement windows work similarly, but with the window handles in the center and no central mullion. Flush casement windows are designed to sit flush with the surrounding frame, offering a sleek and simple aesthetic. These windows became popular in the Edwardian era and are still a popular choice for contemporary homes.

 

Fixed casement windows cannot be opened, making them ideal for "feature" windows. They let natural light into the room and provide a clear view of the outdoors. Awning casement windows are installed horizontally with hinges attached along the top of the frame. They open outwards from the bottom and offer ventilation while protecting against wet weather. Hopper casement windows are also installed horizontally, but their hinges are positioned along the bottom.

 

 

Casement windows come in a variety of materials, including aluminum, uPVC, and timber.

The choice of material depends on factors such as style, insulation, durability, sustainability preferences, and budget. Timber is a popular choice for period properties as it is the most sustainable and authentic option. Advances in timber processing have made it a long-lasting and low-maintenance option, with good quality timber windows lasting up to 100 years. In contrast, uPVC is the cheapest material, but tends to discolor after 10-20 years and isn't as sustainable. Aluminum is known for its security and durability, and is a popular choice for modern homes for its minimalist look.

 

Casement windows have many advantages, including exceptional ventilation, high security features such as multi-point locking and restricted friction hinges with child-resistant catches, and energy efficiency features such as full perimeter draft-proofing and high-performance double glazing. These features help minimize drafts, improve thermal insulation, reduce energy bills, and reduce noise pollution. Casement windows also provide unobstructed views, making them an excellent option for daylight windows.

 

However, there are also some disadvantages to consider when choosing casement windows. Size limitations can be an issue, as the sash has to be light enough to be supported by the window frame while open. This can limit the size of the window in terms of both dimensions and weight. Additionally, casement windows can be impractical if storm screens are needed, as they open outward.

 

 

In summary, casement windows are highly versatile in terms of design, style, and material.

They offer healthy ventilation in the home and help create a warm, peaceful, and secure living environment.
