SF 75

thermally insulated aluminum system

Despite its very low construction depth, the SF 75 aluminum system has comparatively unique thermal insulation properties and is therefore particularly suitable for closing off heated living spaces.

SF 75c

thermally insulated aluminum system with wood cladding

Like the SF 75 system, the SF 75c aluminum system is fitted with a real wood cladding on the inside, but with the added advantage of a thermal insulation which is particularly persuasive during the cold months.

Technical Details (Example SF 55)

Profile system

  • Glass folding partition in ultra-thermally insulated aluminum profiles
  • Bottom-supported construction
  • Rear-ventilated wooden cladding inside (SF75c) (optional)
  • The construction profile depth is 2 30/32” (75 mm) (SF75c = 3 45/64” (95 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
  • Burglar-proofing to resistance class 2 (WK2)
  • Recessed or surface-mounted floor track (optional)
  • Opens to inside or outsidev
  • 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 are locked by rods that engage in the 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
  • The hinges feature pivot pins that cannot be knocked out (anti-intruder feature)
  • The door leaf can be securely clamped to adjacent leaf using snap latches

Runner system

  • Simple adjustment due to 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

  • Glazing configuration of 1 1/32” to 2 1/4" (26 mm to 58 mm) possible.
  • Glazing can be replaced subsequently without difficulty
