Schüco Sliding and Lift-and-Slide System ASS 50

Thermally insulated sliding and lift-and-slide system with level threshold and narrow interlock

The Schüco ASS 50 sliding and lift-and-slide system combines outstanding thermal properties with versatile architectural design options.

The system provides barrier-free transitions thanks to the optional level threshold – perfect for public buildings and an accessible living environment. The narrow interlock with a face width of just 40 mm maximises transparency and emphasises the lightness of modern architecture.

The large-scale vents run smoothly and almost silently, while the design ensures maximum weathertightness. A wide range of fittings, handles and colours enables individual adaptation to diverse design requirements.

For additional comfort and convenience, optional fittings packages are available to make opening and closing the vent units even easier and more secure – ideal for both private and commercial applications.

  • Wide range of designs based on single, double and triple-track outer frames
  • Flat outer frame profile as continuous frame
  • Can be combined with toplights, sidelights and spandrel panels from the Schüco AWS 50, Schüco AWS 60 and Schüco AWS 65 window systems
  • Easy and virtually silent operation of the sliding units coupled with excellent weathertightness
  • Options available for support with operation using Schüco SmartStop and Schüco SmartClose
  • Can be designed as a burglar-resistant solution
  • Barrier-free transitions thanks to optional level threshold for maximum comfort and standard-compliant planning
  • Narrow 40 mm interlock for maximum transparency and slimline face widths

Schüco ASS 50, sliding/lift-and-slide window and door systems
Thermally insulated sliding and lift-and-slide windows and doors with basic depths of 120 mm (for single-track and double-track) and 185 mm (for triple-track).
Burglar resistance in accordance with DIN EN 1627 RC 2

Design features
Available as sliding/lift-and-slide construction with one / two / three guide tracks.
Vent profiles and vent glazing bars with composite strips, one-part (fixed insulating bar) / separated (split insulating bar)
Vent profiles and tandem rollers / roller carriages for vent weights up to 200 kg / 350 kg must be used.
A vent weight of up to 400 kg is also possible with the lift-and-slide version.
The order for the fixed glazing is outer frame / vent frame.
The lower, replaceable tracks are made from stainless steel. In the transition areas, the cover profiles of the outer frame are made from plastic. Availability of vent profiles with optional structural reinforcements in accordance with requirements.
Precise corner cleats are used for the frame joints of the outer frame and vent profiles.
The interlocking section has face widths from 94 mm.
The option of a narrow interlock security keep with a face width of just 40 mm means that transparency in the interlocking section can be increased further.

Enhanced functions:
Barrier-free and accessible level threshold of the lift-and-slide fittings option creates a seamlessly flush connection between the inside and outside areas.

Support spring reduces the operating force required to lift the moving vent and increases comfort levels.
