SF 50

non-thermal aluminium system

This system is based on the SF 45 system. It differs from it primarily by its improved running characteristics. In addition, the greater stability allows a higher wind load as well as the installation of elements of up to 3,800 mm in height without any problems.

SF 50c

non-thermal aluminium system with wood cladding

The system offers all the advantages of an aluminium system, but also creates a homelike feeling for timber lovers due to the cladding of all visible aluminium profiles with real wood on the inside. This makes the interior very comfortable.

Technical Details (Example SF 55)

Profile system

  • Glass folding door with non-thermally insulated aluminum profiles
  • Bottom-loaded construction
  • Rear-ventilated wooden cladding inside (SF50c) (optional)
  • The construction depth of the profiles is 55 mm (SF50c = 75 mm)
  • Air permeability class 4 according to EN 12207
  • Rain tightness class E900 according to EN 12208
  • Resistance to wind load class B4 according to EN 12210
  • Airborne sound insulation value Rw = 36 dB according to DIN EN ISO 140-3
  • Burglar-resistance up to resistance class 2 (WK2)
  • Option of flush or weathered bottom track
  • The flush bottom track is particularly suitable for use in "Barrier-free dwellings" according to DIN 18 025
  • Panel open to the inside or outside
  • Opening of panels by sliding to one side or to both sides
  • Flush running and guide tracks
  • Height variations and expansions may be compensated

Fittings

  • All fittings are concealed within the profiles
  • Low-maintenance, non-corroding and failsafe hardware components
  • Locking of panels in top and bottom track and/or via mushroom head-lock engaging into the frame or adjacent panel
  • Locking and unlocking of panels via flat handles with locking device for burglar resistance
  • Optionally fitted with different lock types
  • Hinges are secured against knocking-out of the pivot pins (burglar resistance)
  • An open turn panel may be securely fixed to the adjacent panel by panel catchers

Running assembly

  • Easy adjustment due to a height-adjustable carriage system
  • The running assemblies are located above the water drainage area
  • Low-noise, wear-, heat- and cold-resistant rollers

Sealing and ventilation

  • Using EPDM gaskets at two levels guarantees rain- and wind-proofness

Glazing

  • A glazing configuration between 8 mm to 36 mm is possible
  • Subsequent replacement of panes without difficulty
