The windbreaks is made of aluminum for the side guides and windshields, inox for its mechanical parts and 2mm galvanized sheet metal for the windshield. It is also possible for all of the above to be made entirely of stainless steel. The windshield operates with an electric motor system for lifting the retractable sheets. The height of the movable sheets is exactly 1/3 of the total height of the construction (not standard). It can be optionally stopped at any location along the route.
