During the World Exposition 2000 in Hannover, Germany, the ‘Duales System’, a German recycling project, had a pavilion that utilized Texlon® ETFE cladding façade and roof. The wall consisted of a three layer system – the two outer layers were printed with a positive and negative leaf pattern. These inflated panels were pneumatically operated to allow the wall to change from translucent to opaque. This enhanced visuals during the performances shown within the building.


The pavilion roof spanning over 25m in diameter was one of the largest Texlon® ETFE ‘cushions’ ever produced in the world. It featured a series of internal fabric tubes that allows the roof to expand or contract to adjust transparency. Texlon® ETFE was selected for its variable transparency technologies and for its low carbon footprint. The Texlon® ETFE technology has an extremely low energy consumption during their manufacturing process, and the complete system weighs between 50% and 90% percent less than alternative transparent cladding systems, further reducing the amount of structural steel and aluminium required to support the cladding.
