Product Options

Product reference:

- SL 97u (standard system):

The bottom fitted runner assemblies run on low noise ball bearings, a combination of stainless-steel rollers with stainless-steel bearing surfaces which give a long service life.

- SL 97o:

The top fitted runner assemblies also run on ball bearings with low noise plastic bearing surfaces.


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).

  • Maximum panel height: 2800 mm (no more than 700 mm wide).

Insulating glass units (2 x 4 mm or 3 x 4 mm) require a midrail starting from a height of 2400 mm. Special sizes are available on request. Refer to technical literature for panel size diagrams. Maximum panel weight: 70 kg.

Exterior frame/ sash cladding:

Aluminium powder coated in a selection of RAL colours.

Interior frame/ sash section:

  • Material: Available in two standard wood 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 3 x 4 mm float glass (k glass). Glass upgrade from 24 mm to 46 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.

Ironmongery/ Accessories:

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

Hinges are finished in EURAS eloxal colours.

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