Thanks to the patented 82 mm thick profile and the triple glass as standard, Winergetic Premium is a window that can achieve excellent thermal performance in any climate. The result of the continuous work of research and innovation at Oknoplast, the Winergetic Premium window uses a special insulating glass made of thin 3 mm sheets, that allow to lighten the weight of the door by 30% compared to a common double glazing with triple glazing. Thanks to this solution and to the thermal treatment of the glass, it will be possible to realize also large doors.
