What are the performance improvements of insulating glass for windows?

Sources:Website | PublishDate:2021.07.12

Glass occupies 80% of the area of the window. The quality of a piece of glass depends on the sound insulation and heat preservation of the window. So, what exactly is the insulating glass we often say? What are its advantages?
First, what is insulating glass? The
insulating glass uses a distance bar to separate the two glasses, and uses butyl glue for sealing treatment to make the middle Multi-layer glass structure with air or special gas. Work is generally indicated by numbers and plus signs. For example, windows are equipped with 5+9+5+9+5 glass as standard, which means three glass and two cavities, 33mm glass layer, including 5mm tempered glass + 9mm hollow layer + 5mm tempered glass + 9mm hollow Layer +5mm tempered glass.
2. Is insulating glass useful for making windows?
Hollow glass can significantly improve the energy-saving effect of windows. The energy consumption of modern buildings is mainly air-harmonic and lighting. The former accounts for 55% of the energy consumption and the latter accounts for the percentage of energy consumption. Of 23. And glass is a thinner and simpler heat transfer material in the outer wall of a building. Since the monotonic agent in the aluminum frame can keep the air in the hollow glass monotonous for a long time through the gap on the aluminum frame, the heat insulation function is better.

3. Highly sound insulation and not easy to fog
Insulating glass can reduce the noise by 27-40 decibels, and the traffic noise of 80 decibels outdoors is only 50 decibels indoors. Assuming that the temperature difference between indoor and outdoor is too large, single-layer glass will be frosted. For insulating glass, since the inner glass in contact with indoor air is affected by the air barrier, the outdoor temperature is -70%, and there will be no condensation on the glass surface due to temperature differences.
Fourth, good wind pressure resistance performance
The wind pressure resistance of insulating glass is 15 times that of a single piece of glass. Glass is not easy to burst. The production method of insulating glass is the bonding method, which is cold working, and the internal stress of the original glass is not changed. The surroundings are sealed with elastic materials, and the glass is not easy to burst.
Five, the film of the coated glass will not fall off
The metal film surface of the coated glass cannot be exposed to the air for a long time. The metal film surface of the coated insulating glass will not fall in the monotonous sealed air.
