To prevent the view into the assembly hall of a primary school, yet to allow daylight to enter the room, a screen facade was installed on the ground floor of the building. This job was done using 38 rotatable separate elements. The elements are fitted on the bottom with igubal® flange bearings and on the top with flange bearings made of iglide® G300. The elements are driven by electric motors. All components used are resistant to temperature variations and withstand any weather conditions.
