Robust façade solution for public school buildings
School buildings are exposed to high loads in everyday life. The demands on materials, design and maintenance are correspondingly high. For the Wiesental school, the focus was therefore not on a short-term effect, but on the question of a durable, robust façade solution that reliably supports the long-term operation of a public building.
The decision in favor of the chosen method was made in the preliminary project and was systematically refined as the planning progressed. The aim was to create a surface that is technically resistant, remains color and lightfast and at the same time blends in precisely with the overall architectural concept.
Solution and implementation
In close cooperation with BWB-Altenrhein AG, an anodized aluminium façade in Permagreen was created for the new Wiesental school building. Permagreen is a color shade from the Permacolor process, an anodizing process with metal salt deposits in which no color pigments are used. The resulting surface is 100% UV-resistant and lightfast, weatherproof and designed for low maintenance.
BWB supported the project with technical advice and comprehensive sampling. Sample series, large-format panels and a 1:1 scale mock-up enabled a well-founded assessment of the color effect, processing and application in façade construction. The final solution could only be reliably determined through the interplay of surface, light and surroundings.
The project is an example of how a clearly defined process, careful sampling and close coordination between planning, execution and surface technology can result in a durable, low-maintenance and design-differentiated solution for public school buildings.
