A curtain wall is the outer covering of a building, with the exterior walls being non structural and designed only to block weather and personnel entry. Due to the fact that the curtain wall facade does not withstand structural loads beyond its own weight, it can be made of lightweight materials. The horizontal wind load on the walls is transmitted to the main building structure through connections on the building floor or columns. Curtain walls can be designed as a system that integrates frames, wall panels, and weather resistant materials. Steel frames have largely given way to aluminum profiles. Glass is commonly used for filling because it can reduce building costs, provide a pleasant appearance on the building, and allow natural light to penetrate into the interior of the building. But glass can also make it more difficult to control the impact of light on visual comfort and solar heating inside buildings. Other common fillers include stone finishes, metal panels, blinds, and operable windows or ventilation openings. Unlike storefront systems, curtain wall systems are designed to span multiple floors, taking into account design requirements such as building sway and movement, as well as thermal expansion and contraction; Seismic requirements; Water diversion; To achieve economical and efficient heating, cooling, and indoor lighting through thermal efficiency.

Curtain walls have become an important type of architecture due to their complete functionality, fast structure, light weight, and significant aesthetic appeal. It is a significant and unique invention in the field of civil engineering.
 
The curtain wall is prefabricated in the factory and assembled before arrival at the site. According to the assembly method of components, there are two common types of curtain wall systems: component type glass curtain wall and unit type glass curtain wall.

1. Component type glass curtain wall

Component type glass curtain wall is a classification form of glass curtain wall, which refers to the production of individual components (columns, beams) and pieces of glass (components) in the factory, and then transported to the construction site to install the columns with connectors on the main structure, and then install beams on the columns to form a curtain wall frame and install fixed glass (components). It is generally divided into several forms, including component type exposed frame glass curtain wall, component type concealed frame glass curtain wall, and component type semi concealed frame glass curtain wall.



2. Unit type curtain wall system

In this type of curtain wall system, the components have already been assembled in the factory. These components are installed as a unit and transported from the factory to the site. This eliminates the need for separate installation. The size of a unit curtain wall is directly proportional to the height of the structural floor. They are very popular in high-rise buildings and do not require external support such as cranes or scaffolding. Only small or temporary cranes are needed. This system has the advantages of fast construction speed and good quality, as the components are manufactured in the factory.
