Wind load resistance

Windows, glass walls and doors should also be able to withstand strong wind. The higher up in a building the corresponding component is installed, the greater the wind load. The wind load to which a building or its components are exposed also depends on the location of the building itself.

Wind load resistance is classified in accordance with the DIN EN 12210 standard: from Class 0 (not tested) to Class 5 (high resistance). In addition, three classes (A, B, C) are distinguished according to the relative frontal deflection under wind load. The final classification of components with regard to their wind load resistance is expressed using a letter-number combination, where the letter indicates the class of relative frontal deflection and the number indicates the wind load class.
