uPVC bi-folding doors

Terrace doors must be functional, and present your garden or terrace in the best possible way. We manufacture three types of terrace uPVC doors: back doors, patio, and bi-folding terrace doors. Just make your choice. Have a look at our bi-folding doors:

  • Produced using a KBE 70 profile system
  • Inward- or outward-opening
  • Higher uPVC frame threshold for superior tightness
  • One-sided handle
  • Siegenia FS Portal fittings
  • Standard colour – white (RAL 9016)
  • Installation ONLY with frame mounting screws (6 mm holes pre-drilled in the frame)
