Building Curtain Wall

1. Ventilated double-layer curtain wall or ventilated curtain wall, as a more popular building envelope, originated in North America and has been widely used in Europe. In terms of ventilation methods, it can be divided into two major systems: internal ventilation and external ventilation. The outer layer of the internal ventilation double-layer curtain wall is a closed structure. Ventilation is performed in the two-layer space of the curtain wall. Usually, the cooperation of a centralized forced ventilation system is required to exchange with the natural world to achieve the final effect. Internal ventilation double-layer curtain wall system is widely used in Italy; external ventilation relies on the external air of the building to rationally organize airflow through the air inlet and outlet of the double-layer curtain wall, and directly exchange with nature to achieve the final effect. Externally ventilated double-layer curtain walls are widely used in Germany and Britain.
