A curtain wall is a type of wall embedded in the exterior of a building. Its functions are as follows, and it has many functional characteristics. For example, curtain walls have functions such as resistance to wind pressure deformation, water tightness, air tightness, seismic resistance, thermal insulation, sound insulation, lightning protection, fire prevention, environmental protection, sound absorption, aesthetic decoration, energy conservation, and so on.
Enclosure function: As the outer enclosure structure of a building, the curtain wall can provide a closed space for the building, resisting external wind, rain, sand, noise, etc., and protecting the internal structure and facilities of the building from the erosion and interference of the external environment. It creates a beautiful outer enclosure for the building and provides a protective function. For instance, it can prevent the impact of heavy rain. In heavy rain with strong wind and large impact of raindrops, with the protection of the curtain wall, the impact and damage to the wall can be directly reduced.

Decoration function: The curtain wall has rich expressive power in appearance. By choosing different panel materials, colors, textures, and shapes, various unique architectural styles and artistic effects can be achieved, making the building more modern and aesthetically pleasing. For example, glass curtain walls can create a transparent and light effect, making the building look simple and grand; metal curtain walls can show a fashionable and tough texture; stone curtain walls can endow the building with a stable and noble temperament.
Nowadays, much attention is paid to the decoration of any product. Because only a beautiful wall can attract people’s attention and make them remember you in a relatively short time. This gives customers a deep memory point. The next time they come to cooperate, the first thing customers will remember is the building with this special and artistic curtain wall design, and it is easier for customers to remember the company. The curtain wall can also provide breathability. Since glass is mainly used in the building, if you want to have a certain degree of ventilation and breathability indoors, you need to make use of the curtain wall as a decoration. The curtain wall is an external decoration, and there is glass inside it, and it is a decoration with the characteristics of opening and closing.
Daylighting function: Especially for glass curtain walls, they have good light transmittance and can provide sufficient natural light for the interior of the building, reducing the dependence on artificial lighting during the day and reducing energy consumption. At the same time, by adjusting the transparency, reflectivity and other properties of the glass, the indoor daylighting intensity and glare can be controlled, creating a comfortable indoor light environment. With this high daylighting function, in high-rise buildings during the day, there is a need for high transparency, and this kind of curtain wall can well meet this daylighting function.

Energy conservation function: The curtain wall can adopt a variety of energy-saving technologies and materials, such as Low-E glass, heat-insulating broken bridge aluminum alloy profiles, thermal insulation materials, etc., to improve the thermal insulation performance of the building, reduce heat transfer, and lower the energy consumption of the building. In addition, some intelligent curtain walls also have functions such as automatic adjustment of ventilation and sunshade, further optimizing the energy-saving effect of the building. The curtain wall also has an energy conservation function, because energy conservation is very important. For a high-rise building, the power consumption of turning on the air conditioner in summer is large. Then the curtain wall can block the direct sunlight and also well protect the indoor cold air from dissipating.
Sound insulation function: The panel materials and structural design of the curtain wall can effectively block external noise from entering the room, providing a quiet space environment for the interior of the building. For example, the air layer between the double-layer glass curtain walls or the filled sound insulation materials can greatly improve the sound insulation effect, so that the interior is free from external noise interference. The curtain wall has a sound insulation function. Because high-rise buildings and residential buildings all need a quiet environment for people to use. If it is a high-rise building by the roadside, an even quieter environment is needed for people to use. Then the sound insulation function of the curtain wall is particularly good. External sounds can be basically blocked and not heard, thus creating a more elegant environment.

Waterproof function: Through reasonable sealing design and the use of waterproof sealing materials, the curtain wall can prevent rainwater from penetrating into the interior of the building, avoiding damage to the building structure and interior decoration. Even in severe weather conditions such as heavy rain, the waterproof performance of the building can be guaranteed. The waterproof function is also one of the important functions of the curtain wall. Waterproof performance is very important, because with the impact of rainwater, the curtain wall can well prevent rainwater from seeping into the room, causing trouble to the indoor staff.
Seismic function: The curtain wall is usually connected to the main structure by a flexible connection method, which can, to a certain extent, adapt to the deformation and displacement of the main structure and has good seismic performance. When an earthquake occurs, the curtain wall can absorb and dissipate seismic energy through its own deformation, reducing the damage to the main structure and improving the overall seismic capacity of the building.
Space utilization function: The curtain wall can moderately separate and integrate the indoor and outdoor spaces of the building, expanding the visual perception of the indoor space. For example, all-glass curtain walls can make the indoor and outdoor spaces penetrate each other, allowing people to enjoy the outdoor scenery indoors and increasing the openness and transparency of the space.
