What is thermal insulation broken bridge aluminum doors and windows: thermal insulation strip is composed of aluminum alloy profile and thermoplastic mixed material heat insulation strip, and rolling heat insulation aluminum alloy profile is made of high-density polyamide PA66 adhesive strip or PVC rigid plastic adhesive strip with good heat insulation function, so that aluminum and plastic can be connected into one. Both hope to push the new type of thermal insulation profile into the market. As an environmental protection and energy-saving product, customers generally accept it. However, the production cost is higher than that of ordinary profiles. It runs through the processes of oxidation, spraying and threading. Broken bridge material from the insulation function and sealing function, the new type of bridge broken energy-saving aluminum alloy window is leading the fashion. The silver oxide white material can be connected with color spray coating, sand fabric and coloring material by connecting the strip and broken bridge, so as to increase the decorative feeling of the profile.
  
The thermal insulation broken bridge aluminum door and window is an improved type based on the old aluminum alloy window in order to improve the heat preservation function of the door and window. The aluminum alloy profile is divided into two parts by strengthening the nylon spacer, which blocks the heat conduction of aluminum. Major aluminum profile manufacturers have been competing for the introduction of foreign heat insulation broken bridge threading equipment, and domestic enterprises engaged in aluminum processing equipment have also developed heat insulation broken bridge threading equipment.

The principle of thermal insulation bridge broken aluminum alloy doors and windows is to use plastic profiles (heat insulation is 1250 times higher than aluminum profiles) to separate and connect two layers of aluminum alloy Indoor and outdoor into a whole, forming a new type of thermal insulation aluminum profiles. Using this profile as doors and windows, its thermal insulation is in the same level as plastic (steel) windows - national standard level, which completely solves the problem of aluminum alloy heat conduction and heat dissipation fast and not At the same time, some new structure matching forms are adopted to solve the old and difficult problem of "the aluminum alloy sliding window is not tightly sealed".

The two sides of the product are aluminum, and the middle is made of plastic profile cavity. This innovative structural design takes into account the advantages of plastic and aluminum alloy, and meets the requirements of decoration effect, strength and aging resistance of doors and windows. The super bridge broken aluminum-plastic profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully realize the gas water isobaric balance, and significantly improve the water tightness and air tightness of doors and windows. The air tightness of this kind of window is better than that of any aluminum or plastic window. It can ensure that there is no dust on the windowsill and floor in the windy and sandy area, and the residents within 50 meters on both sides of the expressway are not disturbed by noise, and its performance is close to that of the casement window.


As building thermal insulation bridge cut-off aluminum alloy doors and windows, can not be separated from the requirements of the building, including installation, lighting, mechanical properties, etc. At the same time, it is necessary to lead out the current in the thermal insulation bridge broken aluminum door and window assembly, which involves the design and selection of junction box, cable, controller, battery and other devices. At present, there is no large-scale application at home and abroad, and demonstration projects are mainly used in China.


According to experts, thermal insulation broken bridge aluminum doors and windows is a new type of building doors and windows, which combines traditional broken bridge aluminum doors and windows with household battery photoelectric conversion technology. It is mainly a new and green energy technology for household power generation. Strengthening the research and development of thermal insulation broken bridge aluminum doors and windows technology has become a new topic to promote the application of renewable energy in buildings. Yang Ge, Standardization Engineer of Shenzhen Chuangyi science and Technology Development Co., Ltd., said that there are 53 compulsory national standards related to the electrical design of aluminum doors and windows with thermal insulation and broken bridges. However, there is no subdivision of relevant standards. The lack of relevant standards at home and abroad makes each design unit, production unit and construction unit design, produce and construct according to their own experience It can reduce the interchangeability and increase the design and maintenance cost of the system.
