How to choose aluminum alloy door and window glass

There are glazes on both sides of the glass. After sanding, the film on the surface of the glass is removed, and a layer of glaze is applied. Once destroyed, the glass is easily broken. Mosaic glass is the most unsafe glass, because it is sharp and sharp after the smash, and the fingers hit the glass fragments and easily scratch the skin. In the process of transporting ordinary white glass, it is also easy to break and hurt people, and it is better to choose less.

Heat absorbing coated glass

The aluminum alloy door and window glass of the Chaoyang or Xitan room should be made of heat-absorbing coated glass; for the room facing the sun or the west, the outdoor side can be made of heat-absorbing coated glass, and the indoor side is made of ordinary white glass.

Since the heat absorbing glass absorbs infrared light, it can attenuate 20%-30% of solar energy incidence, thereby reducing the heat energy entering the room. In summer, the load of the air conditioner can be reduced; in winter, the temperature of the air is increased due to absorption of infrared light, thereby It can resist the cold and achieve energy saving. Since the heat absorbing glass is a color glass, the decorative effect is also obvious while saving energy.

Insulating glass

Insulating glass is more energy efficient. Since the thermal conductivity of the sealed intermediate air layer is much lower than that of the glass, the insulating performance of the insulating glass can be doubled compared to a single piece of glass, and the power consumption of the air-conditioned building can be greatly reduced. Insulating glass can be insulated more than 70% in summer. In winter, indoor heating is not easy to lose, reducing heat loss by up to 40%, and it plays a role of heat preservation, thus turning summer and winter warm into reality.

Tempered glass

Tempered glass is a safety glass. Tempered glass is actually a type of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, impact, etc. Tempered glass is now widely used in high-rise building aluminum alloy doors and windows, glass curtain walls, indoor partition glass, lighting ceiling, sightseeing elevator access, furniture, glass fences and so on.

If both indoor and outdoor glass are made of tempered glass, the impact resistance and safety of the glass are greatly improved both indoors and outdoors. Because the impact resistance of tempered glass is 5-10 times that of ordinary glass, its bending resistance is 3-5 times that of ordinary glass, and the safety performance is greatly improved.

Explosion-proof glass

An ordinary white glass and tempered glass can not withstand the strength of 30-50 kg, but after the lamination treatment, the surface is covered with a layer of things (such as Li Shiyi glass PVC, PT, PP and other explosion-proof glass film into the film ), after strengthening, also called laminated glass, explosion-proof glass.

Ordinary glass can withstand 50 kilograms. After adding laminated glass, it can reach 300 kilograms, which is called explosion-proof glass.

Tempered glass

The tempered glass is a tempered glass and ordinary glass with a decorative film called tempered glass. The tempered glass is based on the existing tempered glass, plus a layer of film that is not easily damaged, called tempered glass.

Ordinary people misunderstand the tempered glass, the PVC film is attached to the glass, and the impact force of the glass is increased. After the impact, it will not hurt people. It can only be called reinforcement, and it cannot be called explosion-proof.
