What You Need to Know About Casement Windows?

Casement windows are a popular choice for many homeowners due to their practical design and energy-efficient properties. Below, we answer some common questions about casement windows to help you decide if they are the right option for your home.

What is meant by casement windows?

Casement windows are side-hinged windows that open outward like a door. They are typically operated with a crank or lever, allowing for easy opening and closing, providing great ventilation and unobstructed views.

What are casement windows for?

Casement windows are primarily designed to provide natural light and ventilation to a room. Their wide opening allows for excellent airflow, and they can also help improve energy efficiency by sealing tightly when closed.

What is the difference between a casement window and a regular window?

The key difference between casement windows and regular windows (such as sliding or fixed windows) is how they open. Casement windows swing outward from the side, while regular windows may slide horizontally or remain fixed in place.

What's the difference between casement and sash windows?

The main difference between casement and sash windows lies in their opening mechanism. Casement windows open outward from the side, whereas sash windows slide vertically or horizontally within the frame. Sash windows are often associated with traditional or period homes.

Are casement windows old-fashioned?

No, casement windows are not old-fashioned. While they have been around for centuries, modern casement windows come in a variety of contemporary designs and materials, making them suitable for both traditional and modern homes.

Can casement windows help reduce energy bills?

Yes, casement windows are highly energy-efficient. Their tight seal when closed helps to reduce heat loss, which can lower energy bills by keeping your home warmer in the winter and cooler in the summer.

What materials are casement windows available in?

Casement windows are available in a range of materials, including uPVC, timber, and aluminium. Each material offers different benefits, such as low maintenance with uPVC, classic aesthetics with timber, and modern durability with aluminium.

How secure are casement windows?

Casement windows are very secure. Their multi-point locking systems and robust frame construction help protect your home against intruders, making them a reliable choice for homeowners seeking enhanced security.

Are casement windows suitable for wet climates?

Yes, casement windows made from materials like uPVC and aluminium are particularly well-suited for wet climates. They resist rot, corrosion, and weathering, ensuring long-lasting performance even in harsher conditions.

Can casement windows be customised to fit my home’s style?

Absolutely! Casement windows can be customised with various colours, finishes, glazing options, and hardware to complement both traditional and modern home styles. You can personalise your windows to match your home’s unique aesthetic.
