Four Panels Casement Style 1

This uPVC casement window is designed as a four-panel unit that combines controlled ventilation with wide fixed glazing, making it a practical choice for larger window openings. The window is manufactured as one complete frame and divided into four vertical panels, with the two outer panels opening and the two centre panels remaining fully fixed.

The left and right panels are bottom-hung opening casements. These panels open inward by tilting from the top, with the hinges positioned along the bottom edge. This type of opening allows fresh air into the room while keeping the lower part of the window secure and stable. Bottom-hung openings are commonly used in uPVC casement windows where ventilation is needed without fully opening the window or taking up extra space inside the room.

The two centre panels are fully fixed glazed sections. Because these panels do not open, they help improve thermal performance by reducing draughts and heat loss while still allowing a large amount of natural light into the space. The fixed glazing also keeps the overall appearance clean and balanced, which is especially important in wider window designs.

This layout offers a good balance between ventilation and insulation. Everyday airflow can be achieved through the bottom-hung openings on each side, while the fixed centre panels maximise daylight and maintain energy efficiency. It’s a configuration often chosen in uPVC windows for living rooms, bedrooms, stairwells, and other areas where light and comfort need to work together.

Manufactured from durable uPVC, the frame is low maintenance and easy to look after. Like other uPVC windows, it does not require painting and can be made to measure to suit different property styles and layouts.

Overall, this four-panel uPVC casement window provides a clean, functional solution that delivers reliable ventilation, strong insulation, and a bright, open feel.
