We were involved in the design and production of this ETFE cushion, one of the biggest ETFE cushions in the world. The cushion is supported by parallel steel cables each 80 cm to remove the wind loads in the surrounding steel construction. Special issues concerning to the security concept and secure drainage of the 9m height cushions brought us a lot of experience and a new project in Costa Rica with a 45 sqm ETFE cushion.
