seele GmbH has its own test centre for proving new types of façade. Loading and performance tests for rain, wind, solar gains and thermal insulation, e.g. thermal cycling tests, are supplemented by special tests for hurricane resistance under realistic conditions. Engineering input and façade designs are tested on full-size mock-ups according to international guidelines and test scenarios developed by seele itself. Individual approval by the building authorities is necessary for virtually every building skin. Motivated by ambition and a passion for solving the apparently impossible, seele explores new ways of building the architecture of the future.
