Why vacuum glass is more expensive than insulating glass

People in the industry know that vacuum glass is more expensive than insulating glass due to its more complex production process, more expensive raw materials and smaller production scale. However, compared with vacuum glass, vacuum home decor glass has better performance and more expensive price. The use of vacuum mouthblown glass has the following advantages:

1. Vacuum glass has extraordinary heat insulation performance. It can be used as window glass to quickly heat up the room in winter, and the indoor heating is not easy to run off. Indoor air conditioning in summer is not easy to escape.

2. Due to the good heat insulation performance of vacuum glass, the surface temperature of indoor window glass does not decrease in winter, and the cold feeling caused by "surface wind" to the wind and the soles of feet is alleviated. It is cool in winter and warm and comfortable in summer.

3. Vacuum glass shall be used for external window glass. With its excellent sound insulation performance, it can prevent noise interference and achieve a quiet environment. The sound insulation performance (± 35dB, maximum 45dB) fully complies with the requirements of Shanghai "Notice on Sound Insulation Windows for New Buildings within 50m on Both Sides of the Road" and is applicable to the existing and planned red lines of expressways and main roads. Within 50 meters from the side, new houses, schools, schools and other buildings will be built on the exterior windows of buildings on the side of the street. It is difficult to realize single glass (<18dB) and insulating glass (<25dB).

4. Because of its excellent heat insulation performance, even if the outdoor temperature is very low, it is difficult to condense on the indoor side of the window glass. It ensures a clear view, does not often clean the condensation of the glass, and can also prevent condensation due to water pollution of walls, curtains and floors, damage to window frames, etc. It can also inhibit the reproduction of molds and wall worms and clean the living environment.

5. With its extraordinary heat insulation performance, vacuum glass reduces the energy emitted by window glass, reduces the cost of heating and air conditioning, and saves energy. For example, experts calculated that the total area of Tianheng Building in Dongzhimen, Beijing is 57000 square meters, The area of doors and windows is nearly 10000? All of these use vacuum glass, 1000 tons of coal per year. More than 1 million yuan of electricity cost was saved. It alleviates the energy pressure of the country and reduces personal expenditure. At the same time, due to energy conservation, the pollution caused by coal and oil combustion has been reduced, and the purpose of environmental protection has been achieved.

In short, the use of vacuum glass is good for individuals, countries and the earth.
