Sky-Frame Classic

The name “Classic” not only evokes the timeless appeal of the rectilinear window assembly, but also highlights its historical significance as the first ever Sky-Frame system. The sliding windows comprise insulating glass units with perimeter aluminium or glass-fibre-reinforced plastic (GRP) sections. Mounted in aluminium frames that are fitted flush with floor and ceiling, the sliding units offer minimum rolling resistance when operated. The system drainage for the flush assembly is via recessed channel or is installed below the raised outdoor floor covering.

Multi-point locking

  • Unlocking handle fitted flat on frame, operated by gentle upward movement
  • Optional: integrable, elegant locking cylinder

  • Plain Hidden, seamless transition


    Hidden, seamless transition

    Plain What sets Sky-Frame Plain apart is the hidden, seamless transition between the inside and the outside that is completely flush-fitted with the floor: the sliding window glides over an opening in the floor with a width of just 10 mm. The space between these tracks is covered by the same flooring as the interior of the room, which reinforces the feeling of a free-flowing transition between indoors and outdoors. Sky-Frame Plain is perfect for use in warmer regions.
