Electric door repair glass insulation and insulation, electric door repair box materials, construction and air tightness are closely related. Building electric door repair whatever form, materials have to use glass, which accounts for more than 70% of household glass area, so the building's energy and electric door repair considerations should first glass. That is why local regulations Beijing, Tianjin, Shanghai and other big cities have been promulgated, and vigorously promote energy-efficient buildings and mandatory, and invariably pursue hollow, inflatable, low emissivity glass reasons.
Japan's government has increased the popularity of electric door repair, and efforts to make the penetration rate reached 50%. South Korea is close to 90 percent penetration rate. In view of the insulating glass production technology is already quite mature, widespread practical use, energy-saving effect is obvious, while investment increased much, so say the building door repair electric energy in the world has entered the era of hollow glass, is also based.
As one of the four envelope components affect building energy consumption of electric door repair, is generally lightweight thin-walled components, is building insulation, heat insulation, sound insulation weak link. gewr_122 especially in the worst heat insulation performance, which passed through radiation, convection transfer, conduction four forms of transfer as a result of air infiltration and energy loss of buildings, energy loss accounts for ordinary single glass building insulation in winter and summer cooling energy consumption 50 %the above. Therefore, electric door repair is to improve the indoor heat, light environment the top priority, its performance directly determines the building energy-saving effect. Reinforced door repair electric insulation properties, reducing energy consumption of electric door repair, is an important step to improve building heat, light quality of the environment, building energy efficiency goals.


Of course, such as hollow LOW-E glass can or SUN-E glass to match, due to its excellent thermal properties of optical, thermal insulation performance is more prominent. In developed countries insulating glass has been widely promoted and applied. Application penetration rate has reached more than US 83%. German government no hollow glass not approved the construction of the proposed building, only 80 years ago the last century, the use of hollow glass Germany reached 210 million square meters, saving energy costs amounted to 5.2 billion marks. Application penetration rate has reached 50 percent in Europe.
Promote the use of hollow glass is a sign of progress of the times, the development of building energy situation dictates. Hollow glass is made of two or more layers of glass sealed air layer therebetween layer filled with the viscosity coefficient and thermal conductivity of the inert gas to reduce the inter-layer convection heat transfer, the main indicators of its energy-saving properties --- Biography heat transfer coefficient K (heat transfer means in a stable condition, both sides of the glass air temperature difference of 1 ° C, the heat transfer within a unit time through one square meter of insulating glass to W / m2K indicate lower .K value, indicating a hollow the better the insulation performance of the glass) of 2.7 to 3.3, while the ordinary monolithic glass 5.8
