The completely renovated and expanded Schulhaus Zentrum now has the Minergie standard, thanks in part to the innovative curtain wall system WICTEC Modul air from WICONA.

The Schulhaus Zentrum Horw, a steel system building from the 1970s, no longer fulfilled the requirements for space, climate skin, building automation, fire safety, etc.

Thanks to its technical features and the attractive design the more or less “new” school attracts plenty of attention. On what is now an area of 7,500 m² there are 28 rooms for classes and groups, two kitchens, a music room, a common room and a management room providing space for everything that a modern school with an ambitious teaching programme requires.
A special visual feature of the façade in Horw is the elements which are opaque from outside but transparent from inside. This is due to a special fabric made by the Swiss company Sefar AG (Heiden).
