SF 20

All-Glass Sliding System

The new SUNFLEX all-glass sliding system SF 20 enables the individual parallel sliding panels to be moved horizontally to one or two sides. On opening and closing the first sliding panel the other sliding panels are automatically opened and closed by integrated followers. The floor-mounted construction means that wide openings can be achieved without additional roof supports. The lower ball-bearing mounted carriages ensure optimum and smooth running of the individual sliding panels. Height compensation of the ceiling rail up to 20 mm and height adjustment of the rollers up to 5 mm allows the sliding system to compensate for structural sagging of the eaves or a lintel without problem and permit quick and simple installation.
