From Our Website

Super Seal are one of Northern Ireland's leading manufacturers of Double Glazed PVC Windows and Doors. We also manufacture GRP Composite Doors (Fire Doors & Secure By Design Doors) as well as Aluminium Windows and Patio Doors. We supply trade installers throughout Northern Ireland and the Republic of Ireland with products of superior quality and offer unparalleled levels of customer service. We strive to maintain high levels of quality in all our products and to constantly improve on the windows and doors which we offer.

Super Seal started out in 1990. Founded by Kenneth Taylor, Super Seal Window Systems Ltd, is one of Ireland's largest trade suppliers of uPVC windows and doors and incorporates PatioMaster Northern Ireland, part of the PatioMaster franchise. We aimed to be recognised as a highly customer focused supplier of UPVC Windows and Doors, providing truly exceptional products coupled with professional service. Today - a highly successful family-run business based in Castledawson - we are proud to be known as just that.

Aluminium Windows and Doors (Bi-Fold, Sliders) are becoming increasingly popular with commercial business and homeowners. Aluminium provides not only greater strength and the desired slim sight lines but is also more resistant to the elements and thus not likely to warp or rot. It is a material with a high strength-to-weight ratio that is easily formed into many shapes and configurations, remaining the most common commercial framing material. Our range of windows are compatible with a range of accessories, locking mechanisms and are available in a wide range of colours and finishes that comply with all relevant British and/or European standards.

At Super Seal we specialise in UPVC composite doors and on first appearance it's difficult to distinguish them from a traditional wooden door. Composite doors are combination of materials put together to form a particularly strong design. Composite doors differ from PVC panel doors in that the sash is manufactured in one solid part rather than having a glazing aperture encompassing an in-fill panel or glass unit. It's this construction that makes a composite door especially secure. This kind of door is highly recommended for exterior doors as in addition to high levels of strength and security, they are also more weather resistant and easier to clean and maintain than traditional wooden doors.

There are now many other window styles available, but the uniqueness of casement windows gives them a certain undeniable charm. Available either side-hung or top-hung, casement windows remain very popular, and today are effective in giving a property a degree of understated class and style. Unlike many types of window, casement windows are capable of being opened all the way. This makes them perfect for letting in air in the summer and providing extra ventilation, adding a high degree of functionality to their aesthetically attractive design.

We produce a full range of windows suitable for both replacement window purposes and for new builds. Our PVC Windows are fabricated using window systems made by Profile 22, the UK's foremost manufacturer of PVC Window frames. Available in a range of colours, finishes and styles, our windows are custom-made by professionals, with a 59mm, 67mm or 80mm outer profile suit your specific purposes.

PVC panel doors are made in a combination of styles and colours with the option of incorporating a traditional in-fill panel or glazed aperture in the opening, giving you a variety of looks and finishes to choose from. The result is an attractive, modern looking door that's great for both front and rear building entrances. PVC panel doors are versatile and infinitely customisable to a customer's specific tastes and preferences. Sidelights or toplights can be added to further enhance the design and provide a greater amount of light within the home.

Whether as an exterior door leading out into the back garden or as part of a conservatory, modern patio doors are every bit as secure as they are attractive and versatile. Sliding patio doors are ideal for completing a conservatory in style, and are the most space efficient option available on the market. Patio doors are particularly effective in bringing light into otherwise dull rooms and for creating a spacious natural ambiance. They can also be used as internal room dividers, providing a more dynamic layout, and provide the option of sliding the patio doors open to create more space, or closing them to provide privacy and as a barrier against sound.
