Sunflex SF20 frameless terrace glazing - AMASVISTA Glass

a cosy place & well protected


The Sunflex SF20 is a frameless glass sliding door system which has a slender top and bottom aluminum rail. Choose from one panel sliding on an extended track, or up to 12 panels all sliding on a six track system. The versatility of this system enables the panels to slide from one side or to both sides creating additional opening options to your room. On opening and closing the sliding doors, each panel collects the next panel for added convenience and effortless operation. The bottom running construction enables large openings to be achieved without additional supports.
The Sunflex SF20 frameless glass sliding door system provides uninterrupted clear views, excellent operating performance and noise reduction. Designed for use as a balcony and patio enclosure or an internal room divider. The system can also be used in a stand-alone external structure. For example as a conservatory
