Aug. 27, 2018

With the rapid development of our national economy and the continuous improvement of people's living standards, as well as the improvement of the architect's design concept of "human nature to architecture", buildings are developing toward high-rise, high-grade, multi-functional direction. Therefore, building curtain wall products are bound to develop in the direction of high-tech and multi-functional, in order to adapt to people's increasing awareness of environmental protection and energy conservation, to meet the market demand for building curtain wall function.

Double curtain wall or ventilation curtain wall as a more popular building envelope structure, originated in North America, has been widely used in Europe. In terms of ventilation mode, it can be divided into two systems: internal ventilation and external ventilation.

Generally speaking, the cost of double curtain wall is much higher than that of ordinary curtain wall, so it is necessary to explore new curtain wall structure to make it not only has the advantages of double curtain wall, but also has the economy of ordinary curtain wall.

The economical double-deck ventilation curtain wall adopts the structure form of integral unit system. The space between inner and outer curtain wall panels is 155mm. The whole structure is light, concise and economical. The curtain wall frame adopts aluminium alloy keel, which is processed, manufactured and assembled in the factory; the surface material adopts Noise Reduction Laminated Glass, single-layer glass and interior insulation decorative board; waterproof and sealant strip (cushion) adopts EPDM or silica gel, and the hardware accessory of aluminum alloy contact parts adopts stainless steel material. And then transported to the scene directly suspended on the main structure of the building.

Noise Reduction Laminated Glass

Glass curtain wall is a kind of building envelope or decorative structure composed of supporting structure system and glass, which can be positioned relative to the main structure and can not share the function of the main structure. There are single and double glazed walls. Reflective insulating glass thickness of 6 mm, wall weight of about 40 kg /, has the advantages of light and beautiful, not easy to pollute, energy saving and so on.

The glass curtain walls of modern high-rise buildings are also made of a combination of mirror glass and ordinary glass, with the insulating layer filled with dry air. The hollow glass is divided into two layers and three layers. The two layers of 15mm Tempered glass are enclosed by two layers of glass to form a sandwich space. The three layers of glass are composed of three layers of glass to form two sandwich spaces. Insulating glass has the advantages of sound insulation, heat insulation, frost prevention, moisture resistance, and high wind pressure resistance.
