What is the price of vacuum glass doors and windows
Vacuum glass of bridge broken aluminum doors and windows is the most important energy-saving building materials. With the continuous improvement of decorative requirements for building doors and windows, the use of glass doors and windows in the construction industry is also increasing. However, when choosing the window glass, people pay more attention to the thermal control, cooling cost and the comfortable balance of internal sunlight projection in addition to its aesthetic and appearance characteristics.
Vacuum glass for doors and windows is a new type of product. It is separated by properly distributed microparticles. The gap layer is only 0.1 mm ~ 0.2 mm. There is no gas in the vacuum cavity, and the vacuum degree is more than 0.1 PA. As a new generation of energy-saving glass, it has better heat insulation and heat preservation performance, which is about 4 times of that of single piece ordinary glass. Due to the high thermal resistance of vacuum glass, it has better anti condensation and frost performance, so it is very beneficial to the winter lighting in severe cold areas.
The energy consumption of building doors and windows is vividly compared to the energy consumption of each non energy-saving window, equivalent to the energy consumption of a tens of watt long-term lamp over the years. In this era of higher and higher requirements for energy conservation and consumption reduction, as the heat loss of the outer door and window glass is the main part of building energy consumption, the use of new glass which can effectively save energy and reduce consumption can greatly reduce the fuel consumption due to heating and cooling, thus reducing carbon emissions.
Vacuum glass is to seal two pieces of flat glass around, the gap between the two pieces of glass is 0.1-0.2mm, the two pieces of vacuum glass generally have at least one piece of low radiation glass, so as to minimize the heat loss through the conduction, convection and radiation of vacuum glass, and its working principle is the thermal insulation of glass thermos bottle The principle is the same. Vacuum glass is the result of the cooperation of glass technology and material science, vacuum technology, physical measurement technology, industrial automation and building science, etc.
Vacuum glass doors and windows are not only warm and comfortable, but also greatly improve the environmental comfort. Can let you in hot summer, still keep indoor comfortable, cool; if in cold winter, keep indoor warm. The thermal conductivity K value of double-layer vacuum glass can reach 0.7 w / m2 · k-0.9 w / m2 · K. If the outdoor temperature is minus 20 ℃, the inner surface temperature of the double vacuum glass is only 3-5 ℃ lower than that of the indoor air temperature. Let you even stand in front of the window, also won't have the cool feeling, can improve the indoor environment's body feeling comfort.
