This four-panel uPVC casement window in a fixed, fixed, fixed, side-hung configuration is designed for wide openings where maximum light is a priority, with the added benefit of controlled ventilation from a single opening section. It is particularly well-suited to larger homes and spacious properties where homeowners want to maximise daylight and create a bright, open feel across wide wall areas. The window is manufactured as one complete unit with four vertical panels set within a single outer frame.

The three fixed panels create a large, uninterrupted glazed area that allows generous amounts of natural light to flow into the room. This makes the window an ideal choice for large houses, open-plan living spaces, and properties with wide elevations where making the most of daylight is important. Because these sections do not open, they also help improve insulation and reduce draughts, making them a strong option within modern uPVC windows where energy efficiency and comfort matter.

The fourth panel is a side-hung opening casement, providing ventilation without breaking the clean, symmetrical appearance of the window. The opening casement can be supplied as either left-hand or right-hand hinged and can open inward or outward, depending on the layout of the room and how the space is used. This flexibility is one of the key advantages of uPVC casement windows, especially in larger properties where layout and furniture placement vary from room to room.

By concentrating the opening function into a single panel, this design keeps most of the window fully sealed, helping maintain strong thermal performance while still allowing fresh air when needed. It works particularly well in large living rooms, dining areas, stairwells, and feature walls where light and views are the main focus.

Manufactured from durable uPVC, the frame is low maintenance and easy to care for. Like other uPVC windows, it requires no painting and only occasional cleaning. The window can be made to measure, making it a practical solution for a wide range of larger residential homes.
