Birds entering facilities is one of the frequent problems encountered in industrial buildings. When designing Coversun, particular attention was paid to the problem which was effectively resolved. The special clamp-on aluminum section and seal system, positioned along the Y-beams of the building, necessary to anchor the Coversun structure, prevents any flying animals from entering the factory. The clamp-on frame system, also eliminates current bird-protection system, used with the traditional curved corrugated or ribbed fiber cement or asbestos cement roofing. It is instead possible to place special metal nets in the motorized ventilation windows to prevent flying animals and foreign bodies originating from outdoors entering. This special characteristic makes Coversun the best product especially for food industry facilities where maintaining an uncontaminated environment is of fundamental importance.
