Heat insulation strip is the German technology. The heat insulation strip is put in the middle of aluminum alloy, so that the temperature inside and outside the frame body reaches a good temperature difference and achieves a good heat insulation effect. By changing the heat insulation strip from 14 to 24, the wider the heat insulation effect is better. First of all, after the aluminum profile of the Broken Bridge is extruded, use a roller gear to roll it into the gear,
Heat insulation strip is the German technology. The heat insulation strip is put in the middle of aluminum alloy, so that the temperature inside and outside the frame body reaches a good temperature difference and achieves a good heat insulation effect. By changing the heat insulation strip from 14 to 24, the wider the heat insulation effect is better. First, after the aluminum profile of the Broken Bridge is extruded, roll the gear into the upper gear and then roll it. There are internal and external sides in China, the interior is white, and the outer side is the color of the outer wall. In foreign countries, it is usually to wear strips first, then spray them on the heat insulation strip, make the temperature in winter and summer reach a comfortable level.
The technology of heat insulation strip comes from Europe, and the domestic good heat insulation system basically comes from Europe. For example, well-known door and window system companies such as hydru, as well as accessory companies, Germany's door and window technology is relatively advanced.
With the continuous improvement of national energy conservation standards, new urban buildings are required to implement building energy conservation standards of no less than 65 in 2015, which may reach 75% in Beijing, Tianjin and other cities, the requirements may be higher and higher, reaching 2.0K.
In the evolution process of K value in Europe, Germany, the pioneer of energy conservation, had a K value of 1.3 in 2010 and reached 1.0 in 2012. The performance of 1.0 was very high. UW = 0.6,UF = 1.0, this is the k value of the window frame, and the door can reach the k value lower than 1.0. In China, there is a temperature division. For example, in cold and warm areas, Changsha belongs to the middle reaches of the Yangtze River and belongs to the yellow area, which is areas with hot summer and cold winter, and the configuration should be around 3.2. Thermal insulation curtain wall can accelerate air flow to achieve better thermal insulation effect.
First of all, the aluminum material transfers heat mainly through three parts through heat insulation strips, heat radiation and hot air flow in the cavity. The boundary of hollow glass is also a key position, which is used most in Wuhan and Changsha by 14.8%.
The design of Pu aluminum 14.8 to Pu aluminum 24.6 is becoming more and more complicated. When K value is 3.6, the whole window reaches 3.2 and 3.3, which can meet the needs of Hunan and Hubei regions. In the future, more and more party A will gradually involve the requirements of heat insulation bar profiles.
The heat insulation strip is connected to both sides, which mainly plays the role of stress. If the heat insulation strip is not good, some accidents may occur. Some heat insulation strips seem to be made of poor materials, so they are made of face brush layers of paint outside, which is easy to break. In fact, there are mainly profiles, hollow glass and hardware accessories. If the glass is broken, one piece can be changed. If the accessories are broken, the whole window and aluminum will be discarded.
