Curtain Wall, also known as suspended, it means that hang suspended on the outside of the main structure of the building light walls. Such wall requires both lightweight, but also to meet their own strength, insulation, waterproof, windproof sand, fire, noise, insulation, and many other requirements. Current material for the walls of a variety of natural stone plate, man-made stone plate (such as colored concrete decorative concrete), composite panels, metal plates and various glass. Curtain connection with the main structure of the use of flexible connectors that bolt through the angle, the walls hung suspended on the outside of the main structure, the formation of the suspension wall, that curtain. Building walls reason why there is vitality in recent years due to the world are working on new technologies and new materials. Over the years, scientists from various countries continue to develop a material having technical characteristics of energy-saving, environmental protection, fire prevention, such as Low-E glass, with thermal insulation properties of aluminum extrusions, vacuum glass, all kinds of man-made curtain wall plates, etc., application of these products greatly promote the development of traditional curtain wall industry. In particular, made a major breakthrough in energy-saving technologies, environmental protection, noise reduction, low-carbon energy in today's economic trends has injected new impetus.

Building walls is able to get a very short time in all areas of construction and promotion of widely used, because it has other materials can not match the unique functions and features:

1, good artistic effect. Curtain artistic effect produced is unmatched by other materials. It breaks the traditional boundaries of the window and the wall, they skillfully blend. It makes the building from different angles show different colors, giving change with the sun, the moon, and the lights around the scene dynamic beauty. This unique bright artistic effects with the surrounding environment organic fusion, tall buildings to avoid the sense of depression, and can change the indoor and outdoor environment, so integration inside and outside views.

2, light weight. Glass curtain wall is compared to other light weight. The case of the same area, the quality of the glass curtain wall painted brick wall about 1/10 to 1/12, is dry hanging marble, granite walls quality 1/15, concrete siding 1/5 ~ 1 / 7. As the quality of building facades of buildings total 1/4 to 1/5, the use of glass curtain walls can greatly reduce the quality of buildings, significantly reducing the impact of earthquakes on buildings.

3, installation speed. Since the curtain wall is mainly composed of a variety of profiles and sheet metal composition, timber specifications can be industrialized, simple construction, no wet work, step less operation, and thus construction speed.

4, updating and maintenance. It can be modified and strong, easy to replace. Because of its single material, light weight, easy to install, so after years of using damaged Change new curtain wall facade is very convenient, maintenance is also easy.

5, the temperature stress is small. Glass, metal, stone and other materials with a flexible frame is connected, reducing the temperature by the temperature change on the structure generated
