PVC Doors & Windows

Welcome to SuperSeal, one of Northern Ireland's leading manufacturers of double glazed PVC Windows , doors and conservatories . We supply trade installers throughout Northern and Southern Ireland with products of superior quality, and offer unparalleled levels of customer service .

Personal service backed up by decades of experience

SuperSeal was founded in 1990 by Managing Director Ken Taylor. Originally a qualified joiner by trade, Ken has over 30 years experience in the construction trade, and it is this in-depth knowledge that drove the company's early development.

Though SuperSeal has grown rapidly since its early days, that personal level of service based on hands on experience remains at the heart of everything we do.

Unlike other suppliers, our staff are not merely call-centre workers with little or no experience of the trade. We pride ourselves on understanding the product and fitting requirements of individual projects, and this enables us to not only provide our customers with high levels of personal service, but to also help them with any technical issues they may have.

At SuperSeal we don't think of ourselves as simply suppliers of double glazing and PVC doors . We aim to provide a full service that few can match. Furthermore, we understand what factors are most important in the double glazing market today to both trade installers and homeowners.

Quality, security and energy efficiency

We strive to maintain high levels of quality in all our products, and to constantly improve on the windows , doors and conservatories which we offer. Energy efficieny is at the forefront of all our product designs, while security has always been a primary concern. Our range of PVC doors and other products utilise Safeware security hardware accredited by the Secured by Design police initiative, so homeowners can rest easy, while those in the trade can be sure of offering their customers secure and desirable products.

Whether you are an installer or a homeowner, you can count on us to deliver top quality PVC double glazed windows, doors and conservatories, and high levels of service to match. Contact us direct or browse our website for more information on our full product range.
