The SL 60 folding system has fixed and tilt-turn elements as part of its suite. The panels can be folded inwards or outwards (bi-folding). A separately operated entry/ exit door can be integrated.


  • Complies with ‘Guidelines for the Verification of the Stability of Metal/ Synthetic Combined Profiles’ (DIBt).
  • Air permeability to EN 12 207. Class 4.
  • Climatic stress to DIN 18 055: Group C.
  • Water tightness to EN 12 208: Class E1200.
  • Windloading to EN 12 210: Class 4B.

The profile system is equipped with multi-chamber insulating cells at the perimeter to meet thermal performance requirements of the EnEV (German Energy Efficiency regulations). Thermal transmission of the aluminium profiles is 2.6 W/m²K, in accordance with DIN V 4108-4:2002-02.

Product Options

Product reference:

SL 60 /u:

The standard arrangement of a bottom running system, with stainless steel rails and floor mounted running gear with three track options. The running gear consists of four stainless steel rollers with a maximum loading of 160 kg. The running gear should lie above the level of water run-off.

SL 60 /o:

A top mounted system. Each running gear unit has four universally jointed (cardanic) rollers for even load spread. The bearings run quietly on a sealed, heat and cold resistant running surface of glass fibre reinforced polyamide. The 200 kg capacity trolleys are height adjustable. There are three track options for bottom track.


Panel sizes are restricted in height and width according to the type of glass used:

  • Maximum panel width: 1000 mm (no more than 2300 mm high).
  • Maximum panel height: 2700 mm (no more than 700 mm wide).

Maximum panel weight: 90 kg.

Maximum glass/ infill weight: 20 kg/m².

Double glazing (2 x 4 mm) requires a glass-dividing rung starting from a height of 2550 mm. Special sizes are available on request. Refer to technical literature for panel size diagrams.

Frame finish:

Standard frame finish/ colours: Powder coating, RAL (9016 or 8077), or EURAS eloxal (E6 EV1 or E6 C34). Other finishes are available on request.


Standard glazing: Insulating glass units with 2 x 4 mm float glass (k glass). Glass upgrade from 5 mm to 40 mm (maximum) possible. Special glazing on request.

Glass is fixed into sills with a continuous snap-in bead to allow trouble-free pane replacement at a later date.

Track system and running gear:

Running and guide tracks are flush-mounted into the system. Low-maintenance, low-rattle, rustproof fittings ensure stability of the system. Height tolerances and expansion are allowed for in the design to prevent operational faults and ensure weathertightness.

Bottom rail is available with or without a threshold, and can be set into the floor. The design without threshold is available for shop fronts or for ‘barrier-free dwellings’ in compliance with DIN 18 025.

– Stacking: Inside or outside stacking.

Ironmongery/ Accessories:

All fittings are corrosion-free and are concealed in the profiles. Panels are sturdily connected by insulated, die-cast corner fittings with integrated hinge pins.

Panels are latched and unlatched by means of internal flat handles with 180° rotation; lockable handles are optional. Handles are available in four RAL colours as standard – other finishes available on request. Aluminium locking bars with minimum 24 mm travel, act on the top and bottom track; bar ends are fitted with polyamide caps to prevent metal to metal contact.

Panel connectors are finished powder coated.

Standard ironmongery for entry/ exit door: Handle inside and outside; three point locking handle and cylinder available as an option for greater security and weathertightness.

Top mounted, inward opening balcony elements are provided with special pins to facilitate cleaning from inside.
