Pavilions require little space, are often installed temporarily and are subject to less complex legal conditions than permanent structures. For these reasons, pavilions can be planned and installed in a much more experimental, even playful manner. For such projects, what would be better suited than a material matching the following criteria: light and economical, translucent and UV-stable, hardly inflammable and extremely resistant to temperature while at the same time applicable multiple times due to its flexibility and resistance to bending and finally completely recyclable.

This poses an extra challenge for the material that has to be highly flexible and resistant to bending. The silicone coating is harmless to the environment and meets all security regulations. The highlight of the structure is an organic photovoltaic plant that is installed over the membrane, complementing the translucent, futuristic look. With this feature, all requirements for energy efficiency are met through least possible material use.

Despite its impressive size (diameter 15m), the Pavilion weighs less than a middle-class automobile. Its small weight stems from the silicone-glassmembrane, confectioned and installed by Hightex. Including some specially developed details, it is attached to the steel-construction from the inside. The material’s high translucency of 21% creates warm and comfortable light inside of the Pavilion. On an area of 170m² and a height of 9m, the Pavilion offers space for exhibitions, seminars and presentation events.

Apart from Apolda, over the next years it will be set up at various other locations in Thüringen and provide citizens with information regarding climate change, environmental protection and responsible use of natural resources.
