ALFRESCO BOTTOM ROLLING BI-FOLD WINDOW SYSTEM
The Alfresco bottom-rolling system for folding windows is the industry's first comprehensive bottom-rolling hardware technology, putting folding windows into any existing building space without major structural changes.
Bottom-rolling systems allow the weight of the window 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.
Industry's first comprehensive technology
Bottom Rolling Bi-Fold Window Systems
Alfresco bottom-rolling system allows for the cost-effective remodel or retrofit of any opening that previously had a sliding window. Now everyone can enjoy the benefits of folding windows, 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 window to carry the weight, whilst remaining easy to manoeuvre. Unlike other bottom-rolling systems, Alfresco controlled windows 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 windows are within reach of every existing building and to every 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 include protective features not available with other systems. These include:
-
Sill covers to avoid dirt collecting in the tracks
-
Guards which work like a snow plough to remove any debris
-
Drainage holes to flush away water and dust
-
The new slimmer frames fit unobtrusively beneath glazed panels with fixed and irremovable adjustment pins providing maximum security.
All these features mean that Alfresco bottom-rolling system folding windows can continue to open and close as new, long past their 10 year guarantee.
