On the external cladding of the building, Sipral employed a mullion facade with strip windows of Schuco RS 60 system. The spandrels between the windows are made of thermal-insulating panels by Hunter Douglas, a Belgian company.Realized in the building interior were three polygonal glazed staircases with semi-structural zoning. On the horizontal dimension there are decorative caps; vertical connections are filled with a sealing compound. Forming an integral part of the design are the inner facades of the atrium. In rendering these, Sipral used the same system as for the external facade.
