Curtain wall from the use can be divided into: building curtain wall, component building curtain wall, unit curtain wall, glass curtain wall, stone curtain wall, metal curtain wall, all glass curtain wall, point support glass curtain wall, etc.
Performance of curtain wall:
1, resistance to wind pressure deformation
2, rain leakage (water tightness)
3, air penetration (air tightness)
4. Deformation in plane (shock resistance)
5, thermal (insulation)
6. Sound insulation
7. Lightning protection
8. Fire prevention
9. Environmental Protection
10. Absorb sound
11, beautiful, decorative
12. Energy Saving
Advantages of curtain wall:
1, light weight
Under the comparison of the same area, the quality of the glass curtain wall is about 1/10 to 1/12 of the whitewashed brick wall, 1/15 of the wet work wall with marble and granite finish, and 1/5 to 1/7 of the concrete hanging plate. In general buildings, the quality of the inner and outer walls is about 1/4 to 1/5 of the total weight of the building. The use of curtain walls can greatly reduce the weight of the building, thereby reducing the cost of basic engineering.
2. Flexible design
The artistic effect is good, the architect can design a variety of shapes according to their own needs, can present different colors, coordinate with the surrounding environment, cooperate with lighting, etc., so that the building and nature are integrated, so that the high-rise building can reduce the sense of pressure.
3, strong earthquake resistance
With flexible design, strong wind resistance and seismic resistance, it is the best choice for tall buildings.
4. Systematic construction
Systematic construction is easier to control the construction period, and the time is shorter.
5. Modernization
It can improve the novelty and technology of buildings, such as photovoltaic energy-saving curtain wall, double-layer ventilation curtain wall and intelligent technology supporting design.
6. Easy to update and maintain
Because it is built in the outer structure of the building, it is convenient to repair or update it.
