Curtain wall (architecture)

A curtain wall is a type of building covering that can be installed on the outside of a building. It is made of many different materials such as glass, aluminum, steel, stone, or wood. It can be used to create a layer of insulation as well as provide a barrier between the inside and outside of the building. The main idea is that instead of having solid walls on the outside of the building, you have sections of glass, metal, or other materials that form a sort of "curtain" around the building. This can help to make the building look more attractive and allow light to enter the building more easily.
