Steel profile system also provide a sealing effect in the event of wind load
Windows, doors and facades consisting of steel profile systems also reliably withstand the pressure of the wind in the event of stormy weather. The wind load that can be expected depends first and foremost on the location of the building – experience has shown that it is stormier near the coast than inland. Germany can be divided into four wind zones with different base wind speeds (wind zone 1: base wind speed 22.5 m/s, 2: 25.0 m/s, 3: 27.5 m/s, 4: 30.0 m/s). However, wind load is also a factor that needs to be considered in the case of high-rise buildings, because: the higher a window is installed in the building and the higher the wind load zone classification, the greater the resistance to wind loads, driving rain and draughts must be.
