Is it necessary to use vacuum glass for home windows and doors?

[China Glass Net] Vacuum glass doors and windows are doors and windows made up of vacuum glass + door and window profiles. The so-called vacuum glass is to use two pieces of glass, one piece is white glass, and the other piece is made of glass powder with the low-radiation film glass (LOW-E glass) sealed with a small support, the thickness of which is 0.1 ~0.2mm, one matrix is formed for every 25mm, the atmospheric pressure is balanced, the vacuum is exhausted at high temperature, and then the exhaust port is sealed with glass to seal it. The pressure in the vacuum layer is 0.1 Pa (one atmosphere is 100000 Pa).

Working principle of vacuum glass insulation, sound insulation and anti-condensation

As we all know, there are three ways to transfer heat, direct conduction B, air convection C, and heat radiation. Since there is no air in the vacuum chamber of the vacuum glass, neither direct conductive medium nor convection can be formed, thus destroying the conduction conditions of A and B, and improving the thermal resistance of the vacuum glass. One of the two glass sheets for producing vacuum glass is LOW-E film glass, and the metal film is placed in a vacuum chamber, which can neither oxidize and ensure the service life, but also fully utilizes the efficiency of reflecting infrared rays, effectively reducing the radiation. Heat spread. In summary, the application of vacuum glass insulation is the principle of thermos. Therefore, its thermal insulation performance is four times higher than that of insulating glass, and is six times higher than that of single-layer glass. A standard vacuum glass insulation performance is equivalent to a 370mm thick concrete wall.

Due to the characteristics of the vacuum glass structure, the presence of the vacuum layer, no sound transmission medium, blocking the transmission of sound, its sound insulation performance is increased by about 10dB than the insulating glass. Sound insulation performance is excellent. There is no air in the vacuum layer of vacuum glass, no more steam molecules, the seal is very strict, the thermal resistance is large, and condensation will never occur in winter.

Vacuum glass door and window performance introduction

The area of the glass on the doors and windows accounts for 70% to 80% of the entire door and window area. The performance of the entire door and window system that changes the door and window profiles without changing the glass is not completely changed.

1. Excellent thermal insulation performance, which greatly improves the comfort of the interior. The heat transfer coefficient of vacuum glass doors and windows is 0.8~1.5W/m2K, which is more than twice the energy saving of insulating glass doors and windows (the heat transfer coefficient of hollow glass doors and windows is K=2.2~3.0W/m2K). After using vacuum glass doors and windows, both cold and heat radiation near the doors and windows are wiped out in the cold or in the heat. Extremely improve the comfort of the home, make your small home more welcoming, and save the cost of heating and cooling air conditioning, a long-term investment.

2, sound insulation and noise, but also your quiet living. With the development of metropolises, high-quality buildings are often located in busy roads such as traffic routes, supermarkets, shopping malls, schools, hospitals, etc., which facilitates your travel, shopping and other life, but also brings noise pollution, making you unable to stay late at night. Sleep, long-lasting neurasthenia, irregular heartbeat, high blood pressure, affecting your work and life, resulting in good health, so there is a market for sound insulation windows. The vacuum glass door and window cut off the sound transmission with its unique structure (the existence of vacuum glass). The sound insulation of the whole window system is RW=39~45dB, which is better than the sound insulation effect of the professional sound insulation window (the sound insulation amount is RW=35dB). about). Vacuum glass doors and windows are installed, even if you are in a busy city, you can still have a quiet room.

3, anti-condensation, so that your vision is open and clear. There is no air and no more steam molecules in the vacuum layer of the vacuum glass. The sealing is strict and the thermal resistance is very high. Dew condensation will never occur in the glass in winter.

4, good security performance, rest assured to use. Vacuum glass doors and windows from the perspective of safety, the outer glass can be used for tempering, laminating and other safety glass, increase the strength, do not hurt people after crushing, please feel free to use.

Vacuum glass door and window product series and configuration
