HOW TO CHOOSE THE GLASS OF ALUMINUM ALLOY DOORS AND WINDOWS

Glaze on both sides of the glass. After playing the sand, smash the glass surface of the film, a layer of glaze, once destroyed, the glass is easy to break. Inlaid glass is very unsafe glass, because of its smashing, are sharp water chestnut, finger touches the glass fragments easily scratch the skin. Ordinary white glass transport process, also easy to break and hurt people, less choice for good.

1. Endothermic coated glass

Exposed to the sun or west drying room aluminum alloy glass doors and windows should be used Endothermic coated glass. In the outside of the room, the heat absorbing coating glass can be selected, and the ordinary white glass is selected on the indoor side. Thanks to heat-absorbing glass absorbs infrared light, it can attenuate 20% -30% of incident solar energy, thereby reducing the heat entering the room. In summer, it can reduce the air conditioning load. In winter, because of absorption of infrared light to increase the temperature of its own, so that it can resist cold, and can also achieve energy saving effect. Because heat-absorbing glass is a color glass, so, while saving energy, the decorative effect is obvious.

2. Insulating glass

Insulating glass is more energy efficient. Due to the thermal conductivity of the sealed middle air layer is much lower than the glass, therefore, the insulating property of the hollow glass can be increased by two times compared to the single glass, and it can greatly reduce the power consumption for the buildings equipped with air conditioning. Hollow glass insulation in summer can be more than 70%, winter can keep indoor heating loss not easy to lost, reduce heat loss up to 40%, played a role in insulation, which will cool summer and winter into reality.

3. Tempered glass

The tempered glass belongs to the safe glass. Tempered glass is actually a prestressed glass, in order to improve the strength of the glass, usually using chemical or physical methods. The formation of compressive stress on the glass surface, glass to withstand external stress first offset the surface stress, thereby increasing the carrying capacity and enhance the wind resistance of their own glass, impact and so on. If indoor and outdoor are use both inside and outside the glass is made of toughened glass, the impact resistance and safety of the glass are greatly improved in both indoor and outdoor. Because the impact resistance of tempered glass is 5-10 times the ordinary glass, the bending resistance is 3-5 times that of ordinary glass, the safety performance is greatly improved.

4. Explosion-proof glass

An ordinary white glass and tempered glass can not withstand the power of 30-50 kg, but after doing the plastic sandwich, the surface is pasted with a layer of things, after strengthening, also called laminated glass, that explosion-proof glass. The original ordinary glass can withstand 50 kilograms, plus a laminated glass, can withstand 300 kilograms, called explosion-proof glass.

5. Reinforced glass

The reinforced glass is a toughened glass and a plain glass attached to a decorative film, which is called a reinforced glass. The reinforced glass is based on the existing reinforced glass and is added to a film that makes it difficult to damage. It is called enhanced glass. Ordinary people misunderstand the reinforced glass. When the PVC film is attached to the glass, it will increase the impact force of the glass, and it will not hurt if it hits the impact. It can only be called hardening, and cannot be called explosion-proof.

Through this simple glass introduction, I hope you will buy windows and doors when the glass can be a little help. Through this simple glass introduction, I hope it  can be a little help when you buy windows and doors glass.
