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 North America. Consumers, both residential and commercial, have never been so conscious of bringing the outdoors in - and the indoors out. Having pioneered the groundbreaking exterior bi-folding window and door technology causing a worldwide revolution in window and door installation, Centor Architectural continues to deliver on the promise of flexible, space-transforming openings which are easily installed and even easier to operate and maintain.   

Ranging from the E Window system to the heavy duty Eclipse E4 (openings up to 57' in width, supporting individual panel weights of up to 265lbs), the four Centor bi-fold systems allow for both inward and outward-folding windows and doors in wood, aluminum, PVC or fiberglass. The no-fuss Centor hardware creates bi-folds out of ordinary book-end doors using advanced Weatherseal technology, built-in systems allow the end-user to make their own vertical and lateral adjustments while stylish, robust Dropbolts anchor closed door panels firmly into place.

Think of the possibilities!  Centor’s bi-fold systems can add flair and flexibility to virtually any application, from a private residence to the most ambitious store front, restaurant or commercial project. Combined with appropriate door panels, they provide the ultimate in weatherproof exterior openings, tested to U.S. sea-coastal hurricane and Canadian standards. Engineered to withstand the most severe weather, the system is just as suited to indoor use, or where exterior doors are required between a sun room and the main part of the house.

Entertainment without the interruption of conventional sliding or hinged doors, views which become vistas, breezes when you please!  Create the magic with Centor bi-fold systems.
