Wall ventilation units

Vertical ventilation is usually done through windows that can be opened. However, there are also situations where other solutions are chosen, such as with automated louvers or flaps in the façade. For daily ventilation, this is an excellent solution that is mainly used in non-residential buildings such as warehouses, industrial and agricultural buildings.

Using a vertical ventilation device in the façade for N-SHEV purposes is of course also possible. However, this requires careful planning/calculation because the ventilation capacity is highly influenced by wind force and wind direction.
