Aluminium curtain wall is designed to resist air and water penetration. It is also used to absorb the building sway induced by wind and seismic forces. Since the structure of these walls is made from aluminium frames, it is sturdy and has space to be filled with glass. Besides, curtain walls are ideal for use because they allow natural light to pass through them, making a building more energy efficient as fewer lights and bulbs are used to ignite the place. Compared with other outer walls, aluminium curtain walls also give an excellent look to the face of the building.
