Why are the sound insulation effects of broken bridge aluminum doors and windows good?

I believe many customers know Fenglu broken bridge aluminum doors and windows, because it is a product of China Aluminum Industry十strong, it is also a well-known trademark in China. Feng Aluminum Industryis the current level of equipment technology in China’s aluminum profile industryComparisonHigh, product seriesalso veryOne ​​of the leading enterprises in the world . So many people choose it. Broken bridge aluminum doors and windows are widely used in construction, transportation, machinery, chemical industry, electronic and electrical, shipbuilding, military industry, aerospace and other fields. Broken bridge aluminum is also called heat-insulating broken bridge aluminum profile, heat-insulating aluminum alloy profile, broken bridge aluminum alloy, cold-breaking bridge profile, and broken bridge aluminum-plastic composite profile. It has superior heat insulation and sound insulation properties than ordinary aluminum alloy profiles to achieve energy-saving and heat preservation functions. In order to save national resources, the National Development and Reform Commission requires ordinary aluminum alloy profiles to gradually withdraw from the market. Broken bridge aluminum doors and windows are a social development trend. Broken bridge aluminum, The“bridge” in the name refers to the insulating material, while the word “break” means action, that is, “to separate the cold and hot bridges.”

Because aluminum alloy is a metal, the temperature conduction is relatively fast, so when the indoor and outdoor temperatures are very different, the aluminum alloy can become a “bridge” that conducts temperature, so that If doors and windows are made of high-quality materials, their sound and heat insulation properties will be poor. The broken bridge aluminum is passedPolyurethaneThermal insulationglueThe aluminum alloy is guided and separated from the middle by temperature. It uses high-strength thermal insulation materials to connect the aluminum alloy profiles. As a whole, it is not easy for heat to pass through the entire material, and the thermal insulation performance of the material becomes better. This is the thermal insulation of broken bridge aluminum doors and windows, and the same sound is used for thermal insulationglue It will also reduce the transmission accordingly. This is the sound insulation of broken bridge aluminum. Break bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. . The thermal conductivity coefficient of broken bridge aluminum doors and windowsK value is below 2W/m2K, which reduces the heat loss by half compared with ordinary aluminum alloy doors and windows, reducing heating costs by about 30%, and the sound insulation It reaches more than 29 decibels, and has good water tightness and air tightness, both of which meet the national A1 category window standards. Although the sound insulation effect of plastic steel and broken bridge aluminum is relatively good, plastic steel is prone to aging over time, while the broken bridge outside the broken bridge has better anti-aging.
