The inner and outer layers of the three-layered ETFE air-filled cushions are partly printed with organic lines and zones that lend the incoming sunlight a vibrant, ever-changing quality. Achieving a harmonious blend with the printed glass panes of the existing architecture was one aim of the printing. In addition, the printing on the membrane cushions ensures that sunlight is reflected, which prevents an excessive build-up of heat inside the building. Together with the architect and the owner, seele cover developed many models to create a unique pattern that was applied with digital printing using a new printing technology. The use of this method also influenced the production of the ETFE cushions, which could be successfully adapted to the new printing method.
The ETFE façade consists of 63 air-filled cushions with identical printing on the inner and outer layers of the three-layered ETFE units. The façade elements ensure an atmosphere filled with daylight inside the extension to the shopping centre. Employing membrane structures for the dome and the façade has resulted in attractive light-filled interior spaces that invite shoppers to take a break.
