SF 50

non-insulated aluminum system

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

SF 50c

non-thermal aluminum system with wood cladding

This unit offers all the advantages of an aluminum system, but also creates a cozy homelike atmosphere with its real wood cladding which covers the aluminum profiles on the interior.

Technical Details (Example SF 55)

Security
The panels are locked and unlocked by a user-friendly single-handed manipulation of robust flat handles. For additional safety, different types of locks are available.

Mushroom head lock
For optimal tightness and burglary resistance, the doorway panel (turn panel) is laterally connected to the frame or the adjacent panel through an additional mushroom head locking.

Safety function panel catcher
In any opening position of the folding sliding system an open turn panel may be safely locked to the adjacent panel by means of safety function panel catchers and be carried along in a controlled way.

Burglar resistance
By means of a safety screw all external hinges are additionally secured against knocking out of the hinge bolts.

Proper handle series
Handles matching the profile design guarantee a harmonized overall picture of the folding system in closed situation and a small panel package when being open.

Twin-Lock mechanism
To guarantee additional safety, the optionally available twin-lock mechanism offers a maximum of security.

Height compensation
The height of the installed folding system may be easily adjusted by a few hand grips, only – this is important in case of eventual structure sagging.

Assembly
The assembly shoes allow a fast and trouble-free assembly of the frame and a fine adjustment of the vertical frame profiles.

Profile system

  • Glass folding partition in thermally insulated aluminum profiles
  • Bottom-supported construction
  • Rear-ventilated wooden cladding inside (SF55c) (optional)
  • Construction profile depth: 2 3/16” (55 mm) (SF55c = 2 30/32” (75 mm))
  • Air permeability class 4 to EN 12207 (Test Certificates for air permeability)
  • Rain proofing class E900 to EN 12208 (Test Certificates for water tightness)
  • Resistance to wind load class B4 to EN 12210 (Test Certificates for resistance to wind load)
  • Sound insulation value (Rw or weighted sound reduction) = STC 36 dB according
  • Burglar-proof to resistance class 2 (WK2)
  • Recessed or surface-mounted floor track (optional)
  • Opens to inside or outside
  • Opens by sliding to one side or both sides
  • Roller track and guide tracks are flush to system faces
  • Design allows for height differences and expansion

Hardware

  • All fittings hidden within profiles
  • Low-maintenance, non-corroding and failsafe hardware components
  • Leaves lock via rods that engage in floor and ceiling tracks and/or via sliding doors that engage in the frames or with the neighboring leaves
  • Locking and unlocking via actuating levers with anti-intruder catches
  • Optionally fitted with different lock types
  • Hinges feature pivot pins that cannot be knocked out (anti-intruder feature)
  • A pivoting leaf can be securely clamped to the adjacent leaf using snap latches

Runner system

  • Simple adjustment due to a height-adjustable runner assembly system
  • Runner assemblies are situated above water drainage collection area
  • Low-noise, hard-wearing, heat and cold resistant running rollers

Sealing and ventilation

  • Rain and wind proofing ensured by EPDM seals at two sealing levels

Glazing

  • A glazing configuration of 5/16” to 1 1/2” (8 mm to 38 mm) possible
  • Glazing can be replaced subsequently without difficulty
