Casement is one of our most popular window styles in Northern Ireland and the surrounding area. This classic ‘open out’ design of window means you can replace windows in both traditional and modern styles of property and enhance the overall appearance. We install our Casement windows across Northern Ireland, including Lisburn and Belfast.

UPVC Casement Windows Made for homes in Belfast and across Northern Ireland

Our PVC casement windows can be manufactured in a range of different styles, sizes and configurations to suit your requirements. Windows can be made fixed or open from the top, bottom left-hand or right-hand sides.

Casement windows can also be connected to create bay window styles and can even be combined with other types of window to create an ideal solution to your needs in Northern Ireland.

PVC is one of the nation's most popular materials as it's highly durable and robust, and is one of the most affordable window option materials available. A high-performance choice, PVC windows can improve your home’s energy efficiency and are available in a range of stylish colours and finishing touches.

Your Turkington windows will be bespoke to you and your home.
