What are broken bridge aluminum doors and windows? Why does this kind of door and window use broken bridge as its name? Li Fan came to tell you the origin of the name of the aluminum doors and windows of the broken bridge.

Bridge broken aluminum doors and windows generally refer to the doors and windows with energy-saving, sound insulation, noise prevention, dust-proof, waterproof and other functions using heat-insulating aluminum alloy profiles and insulating glass. Its profile structure is composed of aluminum alloy and heat insulation resistance bar, which disconnects and connects the aluminum alloy profile, which disconnects the thermal insulation and conductivity properties of the aluminum alloy, and also physically connects the two aluminum alloy profiles, so it is called bridge broken aluminum door and window. The heat conduction coefficient K value of the broken bridge aluminum doors and windows is less than 3W / m2 · K, which reduces the heat loss by half, reduces the heating cost by about 30%, and the sound insulation is more than 29 dB. The water tightness and air tightness are good, which all meet the national A1 class window standard.

The results show that the heat conduction coefficient of aluminum alloy is much lower than that of ordinary aluminum alloy, and the heat conduction coefficient is much lower than that of ordinary aluminum alloy Of heat.

Prevent condensation: the temperature of the inner surface of profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of indoor moisture condensation on the profile surface due to supersaturation. Energy saving: in winter, the window frame with heat insulation strip can reduce 1 / 3 of the heat loss through the window frame; in summer, if there is air conditioning, the window frame with heat insulation strip can reduce the energy loss more.

Environmental protection: through the application of thermal insulation system, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time. Good health: heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows to make it no less than 12 ~ 13 ℃, the most comfortable environment has been achieved.

Noise reduction: the hollow glass structure with different thickness and heat insulation bridge broken aluminum profile cavity structure can effectively reduce the resonance effect of sound wave, prevent the transmission of sound, and reduce the noise by more than 30dB. Colorful colors: after anodizing and powder spraying surface treatment, more than 200 types of aluminum profiles with different colors in ral color system can be produced. After rolling combination, the thermal insulation aluminum alloy doors and windows can produce indoor and outdoor dual color windows with different colors.

Broken bridge aluminum doors and windows have become the new force of domestic doors and windows. The principle of broken bridge aluminum plastic composite window is to use plastic profiles (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 profile. Using this profile for doors and windows, its thermal insulation is in the same level as plastic (steel) windows At the same time, some new structure matching forms are adopted to solve the old and difficult problem of "aluminum alloy sliding window is not tightly sealed".

Shanghai liefan decoration materials Co., Ltd. is a professional manufacturer specializing in aluminum alloy doors and windows, engineering doors and windows, luxury house doors and windows, wood aluminum composite bridge window, environmental protection low-carbon ecological door series, frameless balcony window, leisure sunshine room and supporting mosquito screen window series. It integrates six functions of development, research, production, sales, installation and maintenance. Our factory independently develops all kinds of new heat insulation windows, hollow windows, frameless balcony windows and other fashionable home furnishing products, which have been sold well in many areas at home and abroad. We have undertaken the door and window engineering of large-scale factories and buildings in China, retail and installation projects in Shanghai urban area. Among them, aluminum alloy windows and frameless balcony windows have been sold well for eight years, and are highly praised by the majority of users. With the leading technology, we have successfully launched new type of hollow windows, casement windows and top hung windows of European and American aluminum alloy and met the requirements of foreign investors. The products are exported to Europe, America, Southeast Asia and Africa. With the development and production capacity, the products have become one of the preferred brands of consumers.
