The special design: Structural Glazing. The outside level provides a unified glass envelope. The glass joints are without profile at the outside and project clean modern lines

  • System

    The windows are lowered into a special technical room, where the counterweight is located and all the equipment is installed. The facade is completely hidden and compared to the floor of the room.

  • System

    The panel rises and hides behind the facade in a special case or behind the upper transparent part of the system. Counterweights and automation system are hidden in the side profiles.

  • System

    The overlay for the threshold of the system can be made of any material. Most often it is made from an individual floor covering. Thus, the absolutely flat threshold merges the two spaces together.

  • System

    To increase the thermal and acoustic properties, a pneumatic seal is additionally installed. When the window is closed, the compressor pumps air into the tubular seal, which significantly increases the tightness of the system.

  • System

    A set of laser sensors monitors the space along the descending panel and immediately stops its movement when something enters the monitoring zone.

  • System

    Hirt systems can be telescopic. The panels are connected into each other and when they are lowered, no vertical guides remain for the entire length of the glazed opening.
