The Alfresco bottom-rolling system for folding doors is the industry's first comprehensive bottom-rolling hardware technology, putting folding doors and windows into any existing building space without major structural changes.
Bottom-rolling systems allow the weight of the door to be transferred away from the top of the opening, eliminating the need for a strong and often restricting upper beam freeing up more design space.
Alfresco bottom-rolling system allows for the cost-effective remodel or retrofit of any opening that previously had a sliding door. Now everyone can enjoy the benefits of folding doors, combining the pleasures of a seamless indoor/outdoor lifestyle with fingertip operation.
Alfresco bottom-rolling system is based on simple but sophisticated technology using a range of strategically placed bearings to allow the bottom of the door to carry the weight, whilst remaining easy to maneuver. Unlike other bottom-rolling systems, Alfresco controlled windows and doors glide through tracks, not rails, with movement controlled by articulated carriers, appropriately sized wheels and side thrust bearings.
With Centor's new bottom-rolling technology, quality folding doors and windows are within reach of every existing building and to every door and window manufacturer. Equally suited for easy installation by both DIYers and professionals, the patented system installs with simple hand and power tools and requires no structural changes to the building.
Openings fitted with Alfresco controlled folding windows and doors include protective features not available with other systems. These include:
