In modern buildings, glass curtain walls can be seen everywhere, belonging to a decorative structure, the biggest characteristic is modern, beautiful. There are many classifications of glass curtain walls, and what advantages and disadvantages they will have? Today we follow the glass curtain wall manufacturers to understand.

The basic classification

1. point glass curtain wall (metal support structure point glass curtain wall)

A glass curtain wall is a glass curtain wall composed of the glass panel, point supporting device, and supporting structure. Point glass curtain wall has the characteristics of stable steel structure, lightweight glass and high mechanical strength.

The glass of point glass curtain wall can be fixed reliably through pre-drilled holes on the glass by stainless steel claw, while the glass curtain wall is generally fixed on the frame with structural glue. The surface glass is drilled in the corner and connected to the full glass curtain wall of the supporting structure with metal connectors, while the general glass curtain wall is mostly the structure of the plane frame and vertical rod stress system. Compared with ordinary glass curtain walls, the stress system of the point glass curtain wall is not in the frame, but in the support system.

Glass curtain wall with glass panel by only a few points on the supporting structure is linked together, almost no shade, visual field, the largest glass transparency high limit, so the choice of light pollution on the use of glass white glass, ultra-white glass and Low-E glass, etc., especially the use of hollow glass, saving energy effect is remarkable. But the glass curtain wall has no fans.

2. hidden frame glass curtain wall

Hidden frame The metal frame of the curtain wall is hidden behind the glass. Hidden frame glass curtain walls can be divided into fully hidden frame glass curtain walls and half-hidden frame glass curtains walls. The semi-hidden frame glass curtain wall can be horizontal or vertical. The structural characteristics of the hidden glass curtain wall are: the glass is located outside the aluminum frame, and the glass and aluminum frame are bonded by silicone sealant. A load of the curtain wall is mainly borne by a sealant.

3. Open-frame glass curtain wall

Glass curtain wall is a glass curtain wall that is displayed to the outer surface through metal frame components. A special section aluminum alloy profile is used as the frame, and the glass panel is fully embedded in the groove of the profile. Aluminum alloy profiles have the double function of skeleton structure and fixed glass, which is the characteristic of aluminum alloy profiles themselves. Glass curtain wall is the most traditional structural form, the most widely used, reliable performance. Compared with hidden glass curtain walls, it is easier to meet the requirements of the building technical level.

Second, advantages and disadvantages analysis

1. advantages 

As a contemporary new wall, glass curtain wall endows organic unity of architectural aesthetics, architectural function, architectural energy-saving, architectural structure and other aspects, presenting different colors from different angles, with the change of sunlight, moon, light, giving people dynamic beauty.

Reflective insulating glass thickness of 6mm, wall weight of about 50kg/㎡, with light and beautiful, not easy to pollution, energy-saving characteristics. Add trace metal elements to float glass, toughen into color transparent plate glass, can absorb infrared ray, reduce solar radiation, reduce indoor temperature. Not only can it reflect light like a mirror, but it can also pass through light like glass. The inner side of the glass outside the curtain wall is coated with color metal coating. From the appearance, the whole outer wall is like a mirror. Under the reflection of the light, the interior is not exposed to strong light, and the vision is soft.

2. disadvantages

But the glass curtain wall itself also has its limitations, such as light pollution, energy consumption and so on. The curtain wall of the building is made of coated glass or coated glass. When the sunlight is direct and the sky shines on the glass surface, the reflected glare is caused by the glass mirror (that is, the positive reflection).

However, with the development of glass curtain wall technology and the continuous emergence of new material technology, the materials used for building glass curtain wall have solved the problems of light pollution and energy consumption.
