When you choose glass windows, you may encounter various glass windows for comparison. For example, window manufacturers always say that vacuum glass windows are better than ordinary windows. You maybe feel confused and want to know why. Today we will explain to you about the difference between vacuum glass windows and ordinary glass windows.
Vacuum glass window means that the glass of the window is made of vacuum technology, while ordinary windows and glass are ordinary craftsmanship, and there is no other craftsmanship. Relatively speaking, the performance of such products is not as good as that of vacuum glass windows, but What are the specific differences? Let's make a specific analysis as follows:
• Thermal Insulation Performance
The heat transfer coefficient of vacuum glass is doubled lower than that of insulating glass, the thermal insulation performance is obviously better than that of insulating glass, and the thickness is also doubled. At present, the heat transfer coefficient of energy-saving walls in severe cold and cold regions is required to be 0.4-0.6 W (㎡/K), and a palm-thick vacuum glass window is as thermally insulated as a one-meter-thick wall. Ordinary insulating glass can no longer meet the energy-saving requirements of buildings in severe and cold areas in my country, and Low-E insulating glass cannot meet the index of heat transfer coefficient less than 1. Only vacuum glass can meet the requirements of all energy-saving standards in all regions of my country.
• Anti-condensation and Frost Resistance
Since there is no gas inside the vacuum glass, "internal condensation and fogging" will not occur, and the vacuum glass has high thermal resistance, and its anti-condensation and frost resistance performance is also improved accordingly. Compared with similar insulating glass, vacuum glass is used outdoors. Condensation occurs when the temperature is lower. By the way, the condensation of ICESUN tempered vacuum glass only occurs when the temperature is below minus 50 degrees.
• Sound Insulation Performance
In most frequency bands, especially in the middle and low frequency bands, the sound insulation performance of vacuum glass is better than that of insulating glass, and the overall sound insulation level is higher than that of insulating glass. At present, the sound insulation performance of ICESUN vacuum glass has reached more than 42dB. The average human ear is more sensitive to sounds with an absolute frequency of 1000Hz to 5000Hz, and vacuum glass is effective in this range. The difference in noise is 5dB, and the difference in human hearing is 3 to 4 times.
• Stable Performance
With low melting point technology, aerospace-grade welded glass edge sealing, the same expansion rate and no air leakage, ICESUN vacuum technology can fully guarantee the service life of vacuum glass to 50 years. Whether it is installed in the skylight of the roof or any other position, the thermal insulation performance of ICESUN tempered vacuum glass does not decrease with the change of installation angle and altitude.
