The accuracy and unique look of the products, its sophisticated design and the care of each detail are embedded in any KELLER product, together with the extremely low environmental impact resulting from its energy consumption standards. The more-than-precise fabrication and finishing are the fruit of the perfect marriage between aluminum and glass, in this high-precision quality line that has generated the most minimal systems in the world: a sliding glass with hidden frames and a 21-mm-profile, in special insulated panes ensuring acoustic, thermal, solar factors for the highest performance, and with a surprising easy sliding thanks to the high-tech movementing mechanisms completely hidden in the profiles that are in total co-planarity with the floor, walls and ceilings. A real jewel of the crown that GIOMMI wears with pride and seriousness.
