Features & Benefits

The ideal addition to homes and businesses alike, our efficient aluminium casement windows solutions are a worthwhile investment for a variety of reasons, including:

Excellent Thermal Performance

Our aluminium casement windows can reach low U-values of just 1.0 W/(m²K) (A+). These windows are typically equipped with thermal breaks, which are insulating barriers that interrupt the flow of heat between the interior and exterior of a building. The thermal breaks, usually made of non-conductive materials, significantly reduce heat loss in the winter and heat gain in the summer.

Strong & Durable

Utilising secure locks & handles, our aluminium casement windows are tested to PAS24 standards, offering maximum security with minimal effort.

    Can casement windows be double glazed?

    Yes, casement windows can be double glazed. Double glazing is a common feature in modern casement windows and is used to improve energy efficiency, reduce noise, and enhance security. Casement windows can be double glazed by replacing the existing single-pane window with a double-glazed unit. Alternatively, new casement windows can be manufactured with double-glazed units from the outset. Double glazing can be combined with other features such as low-e coatings and insulated frames to further improve energy efficiency and performance.

    Why do people use casement windows?

    People use casement windows for several reasons: 1.Energy efficiency: Casement windows are known for their energy efficiency because of the way they seal tightly against the frame when closed. This makes them an excellent choice for reducing energy bills by keeping hot or cold air from escaping. 2. Ventilation: Casement windows provide excellent ventilation because they can be fully opened, allowing fresh air to flow into the room. This makes them an ideal choice for areas that need more airflow, such as kitchens, bathrooms, and laundry rooms. 3. Security: Casement windows are difficult to break into because of their design. The window sash is held in place by a crank, making it difficult for intruders to force the window open. 4. Aesthetics: Casement windows are often used in traditional or modern-style homes because of their sleek and simple design. They can also be customized with various frame materials, such as wood, aluminum, or vinyl, to match the style of the home. 5.Easy operation: Casement windows are easy to operate, with a simple crank mechanism that opens and closes the window. This makes them a great choice for people who have difficulty with traditional sliding or double-hung windows.
