A double-glazed window is a glass piece consisting of two or more pieces of glass with aluminum frames filled with molecular sieve adsorbent, located at a certain width of the space, and the edge is sealed and glued with a sealant. The company has a number of automatic insulating glass production lines, a selection of high quality South Glass float glass and various auxiliary insulating materials to ensure that the insulating glass units have the following excellent properties.
A glass product in which two or more pieces of flat glass are separated by supports and sealed around, forming a vacuum layer between the glass.
plate type vacuum glass, support height of 0.1 to 0.5 mm.
side solder tight seal in low temperature.
the built-in getter, vacuum long-term stability.
unique seal and vacuum cavity effectively reduces the heat convection and heat conduction of glass, make its excellent thermal insulation, sound insulation performance.
1, good heat insulation performance
The heat insulation effect of tempered vacuum glass products is 4~6 times that of ordinary insulating glass, and the U value (also called heat transfer coefficient or K value)
As low as 0.4 W/m·K(European IFT laboratory report).
In winter, when the outdoor temperature is -20℃, the inner surface temperature of the vacuum glass is only 3-5℃ lower than the indoor air temperature, which can keep the indoor warm and comfortable.
2, sound insulation effect is good
The sound insulation of vacuum glass can reach 37dB, compound true
The sound insulation capacity of empty glass can reach 39-42dB, which is better than three glass and two cavity hollow glass.
3. Good anti-condensation effect
The vacuum glass is sealed around, and the inside is in a vacuum state. There is no possibility of condensation.
4, wide range of applications, comprehensive cost-effective
The inside of the vacuum glass is a vacuum state, which can be applied to plain and high altitude areas. The hollow glass can be transported to the plateau and low pressure area, and will not expand and crack. Vacuum glass can be used in plain and plateau areas and lighting tops.
5. Long life
Vacuum glass is sealed by inorganic materials, without organic adhesive materials, and processed under the condition of qualified technology through strict high temperature vacuum exhaust, in high temperature, low temperature, high humidity, ultraviolet irradiation and other harsh environment, there will be no performance attenuation, aging failure and other problems.
The suction material is placed inside the vacuum layer, which can keep the vacuum life for 50 years.
On the other hand, the low-E layer in the vacuum glass is located inside the vacuum layer. In view of the high vacuum inside the vacuum glass, it can play a role in protecting the low-E film, which can also ensure the Low U value of the vacuum glass for a longer time and improve the product life.
