Danubeflats Wien

At 180 meters high and with 48 floors, the Danubeflats residential tower in Vienna sets new standards in Austrian architecture. The striking building on the New Danube impresses with its elegant silhouette featuring curved balconies that run around the entire building, providing natural protection from the sun and wind while also reducing operating costs. The light-colored façade forms an attractive contrast to the neighboring DC Tower and creates a striking urban gateway to Vienna's 22nd district.

The architectural challenge lay in the special geometry of the building with its cantilevered floors and continuous balcony rings, which have to withstand enormous static loads – especially from the installed plant troughs with irrigation systems.

Schöck Isokorb® XT K was used for the thermal separation between the ceiling and the balcony slab. With its insulation thickness of 120 mm, the load-bearing thermal insulation element enables a continuous thermal insulation layer despite the challenging rounded facade. The elements were individually adapted in close coordination between Schöck application engineers and structural engineers.

“If Schöck's custom-made option had not been available, we would have had to come up with another solution,” emphasizes Matthäus Groh, Managing Director of KS Ingenieure Wien. His colleague János Kállay adds: “What can be done with reinforced concrete can also be done with Schöck Isokorb®.”

For architects and planners, the project impressively demonstrates how an energy-efficient building envelope can be achieved even with extreme static and geometric requirements.
