Application of new materials in curtain wall construction
In recent years, China’s construction industry has a good development prospect. According to statistics, 1,318 skyscrapers will be completed in the next ten years. China is the country with the largest number of super high-rise buildings under construction and planned to be built ,and a large number of projects in the future will provide demand for the curtain wall construction. At the same time, curtain wall materials are also developing in the direction of light weight, high strength, energy saving, fire resistance, environmental protection and integration. New building materials have become an indispensable link in the modernization of architectural curtain walls.
Under this background, new curtain wall products have gradually entered the field of vision. Among them, terracotta panels have high density, high flexural strength, good impact resistance, energy saving and environmental protection, thermal insulation, and rich products, good safety and strong decoration, gradually replacing traditional stone curtain walls and glass curtain walls, it may be used more in the decoration of curtain walls and internal and external walls of government buildings, airports, subways and other public buildings, greatly promoting the progress of high-rise buildings. At present, there are nearly ten terracotta panel manufacturer in China, such as LOPO Terracotta Corporation.
Application of new curtain wall materials in curtain wall construction:
- Terracotta panel curtain wall
The raw material of the terracotta curtain wall is natural clay, without adding any other ingredients, and will not cause any pollution to the air. The color of the pottery board is completely the natural color of pottery clay. It is environmentally friendly, non-radiate and has a mild color and will not cause light pollution. Moreover, there are up to 14 colors of ceramic plates, which can meet the requirements of architectural designers and owners on color selection. Terracotta panel is a new type of curtain wall material, with good moisture resistance, sound insulation and seismic performance. The terracotta panel is light in weight, flexible and easy to construct, and easy to install and operate. It only needs to connect the curtain wall to the building with metal components, which has good practicality. It is also because of this feature that many high-rise buildings use terracotta panels as curtain wall materials. In view of the low weight and low weight of the ceramic board, it can also effectively reduce the weight pressure of the high-rise building; and the terracotta panel curtain wall is a cavity material, which can effectively reduce the heat transfer coefficient ,and reduce the energy consumption of the building, and make the interior of the building warm in winter Summer cool effect. In addition, the cavity structure of the terracotta panels can also reduce noise and make the indoor environment quieter. These characteristics make the terracotta panel curtain wall material well adopted.
- Stainless steel composite panel curtain wall
Stainless steel composite panel curtain wall has many advantages such as long service life, beautiful appearance, convenient construction design and so on.
At the same time, the stainless steel composite panel is a curtain wall material, which can be finely processed and has a good visual effect, which can enhance the aesthetics of the building and the color of the city. Stainless steel composite panels have good yield strength, relatively low cost, and save 50% to 60% of the cost of similar curtain wall materials. They are inexpensive curtain wall materials, and therefore have been well promoted and applied in many places.
- Photo voltaic glass curtain wall
At present, the photo voltaic glass curtain wall materials have comprehensive characteristics. First, it can effectively meet the needs of building structure and function, and can effectively support the main structure of the building. Second, it has a certain thermal insulation effect, which can play a role in energy saving, and in many cities at this stage, it is used as the first choice material in curtain wall design. Third, it can effectively meet the aesthetic requirements. Photo voltaic glass is different from other general materials in that it has a certain effect of reflecting and refracting light .When sunlight and light change, the color of the glass itself will also change.
In general, with the continuous emergence of new curtain wall materials such as terracotta facade panel, it is still extremely important to choose curtain wall solutions according to local conditions. Not only must economic costs be fully considered, but also environmental adaptability. We must ensure the scientifically and rationality of the curtain wall design as far as possible, deal with the challenges faced in the design of the curtain wall, and make continuous progress in the new curtain wall.
