Why vacuum glass is more expensive than insulating glass

Both vacuum glass and insulating glass belong to building glass. As we all know, the price of tempered vacuum glass is much higher than that of ordinary insulating glass. Let's discuss the specific reasons that safety vacuum glass is more expensive.

People in the industry all know that because the vacuum glass production process is more complicated than the hollow glass, the raw materials are more expensive, and the current production scale is small, the vacuum glass is more expensive than the hollow one. However, compared with vacuum glass, vacuum glass has much better performance and more expensive. The use of vacuum glass has the following benefits:

1. Vacuum glass has extraordinary thermal insulation properties. Use it as a window glass to make the winter room warm quickly and the indoor heating is not easy to lose. Indoor air conditioning in summer, air conditioning is not easy to escape.

2. Due to the good thermal insulation performance of vacuum glass, the surface temperature of the indoor window glass in winter does not decrease, and the feeling of coldness caused by “surface wind” on the inter-wind and the soles of the feet is alleviated. Cool in winter and cool in summer, warm and comfortable.

3. The vacuum glass is used as the outer window glass. With its extraordinary sound insulation performance, it prevents noise interference and achieves a quiet environment. The sound insulation performance (?35dB, up to 45dB) fully meets the requirements of the “Notice for Acoustic Windows in New Buildings Within 50m of Both Sides of the Road” of Shanghai and applies to the existing and planned redlines of expressways and main roads. Within 50 meters from the side, new houses, schools, schools and other buildings will be built on the outside window of the building on the street side. Monolithic glass (<18dB) and hollow glass (<25dB) are difficult to achieve.

4, due to its excellent thermal insulation properties, even if the outdoor temperature is very low, the indoor side of the window glass is also very difficult to condensation, it ensures a clear vision, do not often clean the condensation of glass, but also to prevent condensation due to Water contaminates walls, curtains and floors, damages window frames, etc. It also inhibits the proliferation of mold and wallworms, and cleans the living environment.

5. With its extraordinary thermal insulation performance, vacuum glass reduces the energy dissipated from the window glass, reduces the cost of heating and air conditioning, and saves energy. For example, expert calculations show that the Tianheng Building in Dongzhimen, Beijing has a total area of 57,000? , doors and windows area nearly 10,000? All use vacuum glass, one thousand tons of coal a year. Save electricity by more than a million yuan. It reduced energy pressure on the country and reduced expenses for individuals. At the same time, due to energy saving, pollution caused by the combustion of coal, petroleum, etc. is reduced and the purpose of environmental protection is achieved.

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