What are uPVC windows?
uPVC windows are made from extruded, multi-chambered frame profiles which incorporate chambers designed to retain the warmth inside the room. The chambered design also contributes to its robust and durable performance that will last well and keep your home safe and secure. It is an established manufacturing process in which there has been much innovation in recent years. The combination of profile designs and hinging and locking mechanisms offer a range of designs, including casement, sliding sash, tilt and turn and even bespoke window designs.

A wide range of profile choices to get the look you want in a range of colour finishes

Energy-efficient double-glazed uPVC windows
Our highest-rated double glazed windows have an energy A+ rating, so you can be sure that they’ll keep the inside of your home at an optimum temperature.
