Knowledge explanation of broken bridge aluminum doors and windows

As people pay more and more attention to balcony space, the functional requirements of balcony windows are getting higher and higher. Broken bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. . How much do you know about broken aluminum doors and windows?

　　Broken Bridge Aluminum Advantages:

1. Reduce heat conduction: the use of thermally insulated broken bridge aluminum alloy profile, its thermal conductivity coefficient is 1.8～3.5W/㎡·k, which is much lower than ordinary aluminum alloy profile 140～170W/㎡·k; adopts hollow glass structure, its thermal conductivity coefficient The value of 2.0～3.59W/m2·k is much lower than that of ordinary aluminum alloy profiles of 6.69～6.84W/㎡·k, which effectively reduces the heat conduction through doors and windows.

　2. Prevent condensation: the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, reducing the possibility of indoor moisture condensing on the surface of the profile due to oversaturation.

3. Energy saving: In winter, window frames with heat insulation strips can reduce 1/3 of the heat lost through the window frames; in summer, if there is air conditioning, window frames with heat insulation strips can Reduce energy loss more.

　　4. Protect the environment: Through the application of heat insulation system, energy consumption can be reduced, and environmental radiation caused by air conditioning and heating can be reduced at the same time. Good for health: The exchange of heat between the human body and the environment depends on the temperature of the indoor air, the air flow rate and the outdoor air temperature. The most comfortable environment has been achieved by adjusting the indoor temperature of doors and windows so that it is not lower than 12～13℃.

　　5. Noise reduction: The use of hollow glass structures with different thicknesses and a cavity structure of thermally insulated aluminum bridges can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30dB.

　　6. Colorful colors: aluminum profiles of different colors can be produced after surface treatment with anodizing, powder spraying, and fluorocarbon spraying. After rolling and combination, the insulated aluminum alloy doors and windows produce indoor and outdoor two-color windows with different colors.

Broken bridge aluminum performance:

　　 1. Broken bridge aluminum doors and windows have good thermal insulation. The inner and outer frames of the heat insulation profile are combined with the softness. The frame adopts a three-sealed form of one rubber strip and double tops, which is tightly closed, has excellent airtight and watertight performance, and has excellent thermal insulation performance; the window sash adopts hollow glass structure, which makes the window truly soundproof , Heat insulation, heat preservation, excellent functions, a large amount of savings in heating and cooling costs, the heat transfer coefficient K value is tested to be 2.23—2.94w/2K or less, the energy saving effect is significant, and the energy saving costs in several years are enough to make up for the initial investment.

　　2. Waterproof function of aluminum doors and windows of broken bridge. The structural drainage system is designed using the principle of pressure balance, and the slope is designed to slide down and stepped, with drainage outlets, smooth drainage and good water tightness.

　　 3. Broken bridge aluminum doors and windows prevent condensation and frost. The broken bridge aluminum profile can realize the three-way sealing structure of the doors and windows, reasonably separate the water vapor cavity, successfully achieve the equal pressure balance of air and water, and significantly improve the water tightness and air tightness of the doors and windows, and achieve the effect of clear and bright windows.

　　4. Design of anti-mosquito screens for broken aluminum doors and windows. The invisible screen window can be installed and used inside and outside. It has anti-mosquito and flies, especially suitable for mosquito-prone areas in the north.

　　 5. Anti-theft and anti-loose device for aluminum doors and windows of broken bridge. Equipped with standard hardware locks to ensure the stability and safety of the windows in use.

　　 6. Broken bridge aluminum doors and windows prevent noise and sound insulation. The structure has been carefully designed and the joints are tight. According to the test results, the air sound insulation can reach 30-40db, which can ensure that residents within 50 meters on both sides of the expressway will not be disturbed by noise, and the neighboring downtown can also ensure that the interior is quiet and warm.

　　7. Fireproof function of aluminum doors and windows of broken bridge. Aluminum alloy is a metal material, and the material of the insulation strip is PA66+GF25 (commonly known as nylon insulation strip), which does not burn and has good high temperature resistance.

　　 8. Broken bridge aluminum doors and windows, sand and wind resistance. The straight material of the inner frame adopts a hollow design, which has strong resistance to wind pressure and deformation and good anti-vibration effect. It can be used in high-rise buildings and civil residences. Large-area windows can be designed with large lighting area; this kind of window has good air tightness and can ensure that indoor windowsills and floors are dust-free in areas with heavy sandstorms.

　　 9. Broken bridge aluminum doors and windows have high strength and no shape, maintenance-free. The aluminum window of the broken bridge has high tensile and shear resistance and high resistance to thermal deformation. The aluminum profile of the broken bridge is not easy to be corroded by acid and alkali, is not easy to turn yellow and fade, and almost no maintenance is required.

　　 10. Broken bridge aluminum doors and windows have a variety of colors and are very decorative. Different colors of indoor and outdoor surfaces of doors and windows can be achieved, meeting customers' preference for color effects, color gamut space aesthetics, and meeting the individual design requirements of architects. The aluminum profile adopts streamlined design with luxurious style.

　　11. Broken bridge aluminum doors and windows, green building materials, circular economy. Broken bridge aluminum doors and windows not only produce no harmful materials during the production process, but all materials can be recycled and reused. They are green building materials and environmentally friendly products, which are in line with human sustainable development.

　　 12. Broken bridge aluminum doors and windows have many opening forms, which are comfortable and durable. There are flat opening, inward tilting, top suspension, push-pull, flat opening and inward tilting combined type, etc.
