Many suppliers specialise in just one or two window systems, not giving you much flexibility if you want to offer your customers a wide choice. At Synseal Group we manufacture four leading PVC-U systems and the hugely popular WarmCore warm aluminium system, giving you more options to satisfy all domestic and commercial, new build and renovation projects.

Our full range includes casement, flush sash, tilt & turn, vertical sliders, top reversible, bow, bay and specialist curved windows using our own state-of-the-art machinery. 



With a wide range of window styles using various material options, our window systems are recognised as market-leaders. Using the latest innovations, Synseal Group will remain at the forefront of fenestration for many years to come with our wide range of Brands.
