Innovation meets high energy efficiency and minimal aesthetics.

This system has the same features with GV42000 in difference that the panel frame is hidden – Hide Sash. The implementation of this system is possible with aluminum panels or wood with a specific configuration around to cover the sash. Thus, at the entrance we see the face height of 67 mm perimetrical frame and the surface of the panel seamlessly with optimum architectural result.

Optionally, with the same system the  opening can be achieved by rotation of the panel around an offset axis at a selected point. In this case there is the possibility of oversized dimensions sheet of a weight of up to 400 kilos
The absolute minimalist aesthetics achieved with the same entrance system GV44000 when on the construction there is the ability to hide also the door frame so that the only visible part across the opening will be the rotating panel.
