The SL 67 folding system can be combined with other fixed and tilt-turn elements.

The design of the external ventilated aluminium cladding follows the guidelines for aluminium/ wood windows of the Institute for Window Technology e.V., Rosenheim.

Product Options

Product reference:

SL 67u (Standard system):

A bottom running system with stainless steel rails. Floor mounted running gear has four stainless steel rollers with a loading capacity of 200 kg. Uses top track 5-66-08-x.

SL 67o:

A top mounted system. Top-mounted running gear units have four universally jointed (cardanic) rollers for even load spread. 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. Uses top track 5-66-05-x.


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

Bottom running:

  • Maximum panel width: 1000 mm (no more than 2200 mm high).
  • Maximum panel height: 2800 mm (no more than 600 mm wide).

Top hung:

  • Maximum panel width: 1100 mm (no more than 2200 mm high).
  • Maximum panel height: 2800 mm (no more than 700 mm wide).

Maximum panel weight: 70 kg.

Insulating glass units (2 x 4 mm) require 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.


Exterior frame/ sash cladding: Aluminium.

  • Finish: Powder coated in RAL colours.

Interior frame/ sash section: Wood – available in three standard species. Consult Solarlux for availability of alternative species.

  • Finish: Undercoated (Standard finish) – colour from SL colour card. Optional final finish of wood surfaces – colour from SL colour card.

Glazing details:

Standard glazing: Insulated glazing units with 2 x 4 mm float glass (k glass). Glass upgrade from 24 mm to 30 mm (maximum) possible. Special glazing is available on request.

Dry glazed with flush sills to allow for trouble-free pane replacement at a later date.

Track and running gear:

Running and guide rails are flush-mounted into the system. Height tolerances and expansion are allowed for in the design to prevent operational faults and ensure weathertightness. The bottom rail is available with or without a threshold and can, as an option, 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.

Aluminium track for top-hung applications can be EURAS eloxal coated in one of two colours.

Ironmongery/ Accessories:

All fittings are corrosion-free and concealed within the profiles. Low-maintenance, low-rattle, rustproof fittings ensure stability of the system.

Panels are latched and unlatched by means of internal flat handles with 180° rotation; lockable handles optional. Handles 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.

Hinges are finished in EURAS eloxal colours.

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

Fasteners are width-adjustable for optimum adjustment of the folding system and equipped with secured hinges to hinder break-ins.
