Sometimes side vents aren’t enough. If you want balanced ventilation across the entire bay, this three-panel design gives you exactly that.

With one flat centre section and two angled sides, this configuration keeps the classic bay shape. The difference is that all three panels include discreet top-hung vents. That means airflow isn’t limited to the corners — fresh air can circulate evenly across the whole window.

A Balanced Bay with Ventilation Across Every Panel

Unlike fixed-only uPVC bay windows, this layout gives you flexibility. Each vent opens outward from the bottom while remaining secure and subtle in appearance. The lower sections stay fixed, preserving the structural strength and clean lines of the frame.

Compared to standard flat uPVC windows, a bay projection naturally increases daylight from multiple angles. Adding vents to every section makes the window far more practical for everyday living, especially in living rooms and larger front-facing spaces.

Manufactured using modern uPVC systems, the frame delivers strong thermal performance with very little maintenance required. It’s built to handle UK weather conditions while maintaining a sharp and tidy appearance year after year.

This option works particularly well if ventilation is a priority, but you don’t want to compromise on symmetry or light.
