What is broken bridge aluminum alloy door and window, why call broken bridge aluminum door and window?
Thermal insulation aluminum profiles and insulating glass are adopted for the bridge breaking aluminum doors and windows, with European style structure, beautiful appearance, energy-saving, sound insulation, noise prevention, dust-proof and water-proof functions. The heat conduction coefficient K value of this kind of broken bridge window 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. At present, the brands of broken bridge aluminum doors and windows in the market are: Guangdong fengaluminum, Zhongwang broken bridge aluminum, Central Asia broken bridge aluminum, Beixin broken bridge aluminum, etc.
Advantages of bridge broken aluminum alloy doors and windows:
1. Good thermal insulation: the thermal conductivity of plastic in aluminum-plastic composite profile is low, and the thermal insulation effect is 1250 times better than that of aluminum. In addition, it has good air tightness. In cold areas, although it is dozens of degrees below zero, indoor is another world.
2. Good sound insulation: the structure has been carefully designed and the joints are tight. The test results show that the sound insulation is 30dB, which meets the relevant standards.
3. Impact resistance: because the outer surface of aluminum plastic composite profile is aluminum alloy, its impact resistance is much stronger than that of plastic steel window profile.
4. Good air tightness: the gaps of aluminum plastic composite window are equipped with multiple sealing strips or rubber strips, and the air tightness is grade I, which can give full play to air conditioning interaction and save 50% energy.
5. Good water tightness: the doors and windows are designed with rain proof water structure to completely isolate the rain water from the outside, and the water tightness meets the relevant national standards.
Fire resistant material is aluminum alloy, 6.
High quality burglar proof and aluminum lock, no hardware
8. Maintenance free: aluminum plastic composite profile is not easy to be eroded by acid and alkali, will not turn yellow and fade, almost no maintenance is needed. When dirty and dirty, can be washed with water and detergent, clean as before after cleaning.
9. Best design: the aluminum-plastic composite window is scientifically designed and adopts reasonable energy-saving profiles. Therefore, it has been recognized and praised by the national authorities, which can add luster to the building.
