Tillner & Willinger ZT GmbH
The office building lies on the edge of bustling Praterstern square, the most attractive open space resource in the city of Vienna. Covering an area of about 5,000 m², the new 8-floor office building consists of two almost parallel structures with a central atrium.
Although eight different facade types were used the highlight of the office building is the Texlon® ETFE Foil Roof. With a span of 26 m, the construction covers an area of about 1,000 m² and is supported on 13 steel trusses. Thanks to Vector Foiltec’s Texlon® ETFE Roof System, the supporting structure is considerably lighter than would be necessary for a glass roof. What's more, the double layered ETFE foil exhibits a certain self-cleaning effect due to the chemical surface properties, and provides solar shading as well as thermal insulation.
