1. Superior energy-saving effect: the energy consumption of modern buildings is mainly air conditioning and lighting. The former accounts for 55% of the energy consumption, while the latter accounts for 23% of the energy consumption. Glass is a thin and easy heat transfer material in the outer wall of buildings. Because the desiccant in the aluminum frame keeps the air in the glass hollow dry for a long time through the gap above the aluminum frame, the insulating performance of the insulating glass is good.

2. High sound insulation: hollow glass can reduce the noise by 27-40 dB. When the traffic noise of 80 dB outside reaches the indoor level, it is only 50 dB.

3. Eliminate frost and dew: if the temperature difference between indoor and outdoor is too large, the single-layer glass will frost. For insulating glass, because the inner glass in contact with the indoor air is affected by the air partition, even if the outer contact is very low, it will not condense on the glass surface due to the temperature difference. The dew point of insulating glass can reach -70 ℃ (excluding adhesive strip insulating glass).

4. Improved wind pressure resistance: the curtain wall mainly bears wind load, and wind pressure resistance becomes the main index of the curtain wall. The wind pressure resistance of insulating glass is 15 times that of single glass.

5. Glass is not easy to self explode: the production method of insulating glass is bonding method, which is cold processing. The internal stress of the original glass sheet does not change, and the surrounding is sealed with elastic materials, so the glass is not easy to self explode.

6. The film layer of coated glass will not fall off: the metal film surface of coated glass cannot be exposed in the air for a long time, while the metal film surface of coated hollow glass will not fall off in the dry sealed air.

7. The original glass sheet will not burst: in an air-conditioned room, in summer, the outside of the single characteristic glass is directly exposed to the sun, gathering heat. There is a temperature difference between the inside and outside of the glass. When the temperature difference is too large, the glass will burst. This phenomenon exists in insulating glass.

8. Application scope of insulating glass: doors and windows, ceilings of buildings, schools, hospitals, stadiums, television, radio recording rooms and other places that need sound insulation, and it can also be used in refrigeration appliances, aircraft, ships, locomotives and other fields.
