The automatic sliding door FST is designed to offer solutions for the operation of balcony or terrace doors where a high sealant is required. Standard automatic doors do not provide a watertight or as high resistance as that provided by FST doors. This can be achieved with the use of window profiles from any curtain-wall system. Together with the clever FST design, a sealed, comfortable and secure system is provided. The innovation behind the façade/ terrace sliding door is the pop-out drive system that slides out of the façade and positions the leaf parallel to the fixed side screen. During closing the door again slides automatically back into the façade opening and closes flush. The FST system is available in a manual or automatic (dead-man controlled) version.


  • Sealed and secured terrace/ balcony door where no conventional automatic door could provide a solution.
  • Aesthetically designed with a fully flush outer skin that offers an unique and impressive look, provides a secure and totally unique solution.
  • Comfortable use even for large door leaves at your balcony or façade opening.
  • Air and water tightness solutions in different designs available.
  • Window functions, system can be stopped anywhere for ventilation purposes.
  • APS design for high sealant and security requirements by using a standard window profile.
