Creating Systems for Windows and Doors

Creating seamless transitions between indoor and outdoor spaces! That's the challenge being put to designers and window and door manufacturers right across Britain and Europe. Centor Architectural pioneered the groundbreaking exterior bi-folding window and door technology causing a worldwide revolution in window and door installation and continues to deliver flexible, space-transforming hardware with the functional precision and durability demanded by discerning specifiers and end-users.

Easily installed and even easier to operate and maintain, the no-fuss Centor bi-fold hardware creates bi-fold windows and doors out of any style of door panel. Advanced Weatherseal technology ensures an uncompromised internal environment, stylish robust Dropbolts anchor door panels firmly into place while built-in systems allow the end-user to make their own vertical and lateral adjustments. Ranging from the E Window system to the heavy duty Eclipse E4 (openings up to 17600mm in width, supporting individual panel weights of up to 120kg), the four Centor bi-fold systems allow for any configuration of inward or outward opening windows and doors in wood, aluminium, PVC or fiberglass. Custom premium grade stainless steel bearings guarantee silky smooth operation while the quality manufacture is underpinned by Centor’s 10-year warranty.

Centor’s bi-fold systems can add flair and flexibility to virtually any private residence or commercial application. Engineered to withstand the most severe weather, the system is just as suited to indoor use, or to link a conservatory to the main house. Entertainment without the interruption of conventional sliding or hinged doors, views which become vistas, breezes when you please! Centor bi-fold hardware systems rise to the challenge with quality you can feel, and ever so faintly hear.
