What is a curtain wall?
A curtain wall is a cladding structure that hangs on the exterior wall of a building like a curtain. It does not bear any weight, nor does it play a role in the main structure or load-bearing. Generally, curtain walls are lightweight and strong, and they are also aesthetically pleasing, so they have a certain decorative effect on buildings. Curtain walls are the exterior wall cladding of a building, comprising panels and a support structure system.
Performance of curtain walls
Air permeability.
Good fire resistance and environmental friendliness.
Strong wind resistance and anti-deformation under pressure.
Waterproof and leak-proof.
Very beautiful appearance, thus serving as a decoration.
Very energy-efficient.
Planar deformation and seismic resistance.
Thermal insulation.
Sound insulation and lightning protection. Curtain walls including stick-type curtain wall are usually used on the outer side of the main structure and are generally covered on the surface of the main structure. Curtain walls are an independent and complete structural system. Curtain walls have a certain micro-movement capability relative to the main structure in the plane.
Advantages of curtain walls
Lightweight of curtain walls
In the comparison of the same area, the weight of a glass curtain wall is about 1/10 to 1/12 of that of a painted brick wall, and 1/15 of that of a marble or granite finish, and 1/5 to 1/7 of that of a concrete hanging panel. Using curtain walls can greatly reduce the weight of the building and thus reduce the foundation engineering cost.
Modernization of curtain walls
Can enhance the novelty and technology of buildings, such as the design of photovoltaic energy-saving curtain walls, double-layer ventilation breathing curtain walls, and other designs that match with intelligent technology.
Strong seismic resistance of curtain walls
Because unitised curtain wall system is all designed flexibly, they have strong wind and earthquake resistance and are the best choice for all high-rise buildings.
Flexible design of curtain walls
Curtain walls have a particularly good artistic effect. Architects can design various shapes according to people's needs and choose different colors to make them more coordinated with the surrounding environment. Coordination with lighting can also give the building a different visual effect. It can also reduce the sense of oppression of tall buildings.
Systematic construction of curtain walls
Systematic construction can better control the construction period, and the time-consuming is relatively short.
Convenient maintenance and replacement of curtain walls
Since they are built on the outer structure of the building, it is easy to maintain and replace them.
