Benefits & advantages

  • solution for shading asymmetrical window shapes (upper frame is not horizontal, but inclined at a certain angle)
  • slats copy the angle of the upper frame and are parallel to it
  • the aluminium slats are guided in a steel string
  • a special mechanism compensating for the different lengths of textile straps when sliding down and lifting the blind
  • telescopic bottom slat, which is used to compensate for the different width of the bottom slat in the lower position (window width) and upper position (length of the sloping part of the window)
  • low height of the roll is achieved by using slats without a longitudinal fold of the slat
