Aluminum and plastic composite doors and Windows of broken bridge are made of insulating aluminum profile and insulating glass, which is similar to European style structure.The heat conduction coefficient K of aluminum doors and Windows under the bridge is 3W/m2·K, which is half less than that of ordinary doors and Windows, and about 30% less heating cost. The sound insulation is over 29 decibels, and the water tightness and air tightness are good, both reaching the national standard of A1 Windows.
Performance and advantages of broken bridge aluminum:
1. Good insulation property of broken bridge aluminum: low thermal conductivity of plastics in aluminum-plastic composite profile, heat insulation effect ratio convergence?250 times, and with good air tightness, the interior is a world away in cold regions, even if it's minus a few dozen degrees outside.
2. Good sound insulation of broken bridge aluminum: its structure is carefully designed with tight joints, and the test results show that the sound insulation is 30db, which conforms to relevant standards.
3. Impact resistance: the external surface of aluminum/aluminum/plastic composite profile of broken bridge is aluminum alloy, so it has much stronger impact resistance than the profile of plastic steel window.
4. Good air tightness of the broken bridge: multiple sealing woolen strips or rubber bands are installed at every gap of the aluminum-plastic composite window of the broken bridge. The air tightness is the first level.
5. Good water tightness of broken bridge: the doors and Windows are designed with rainproof structure to completely isolate the rain water outside, and the watertightness conforms to the relevant national standards.
6. Good fire-resistance of broken bridge aluminum: the broken bridge aluminum and aluminum alloy is a metal material and does not burn.
7. Good anti-theft property of broken bridge aluminum: broken bridge aluminum and aluminum plastic composite window, equipped with excellent hardware accessories and high-grade decorative locks, making thieves helpless
8. Free maintenance of broken bridge aluminum: the composite profile of broken bridge aluminum and aluminum plastic is not easy to be corroded by acid and alkali, and will not yellow and fade. Maintenance is almost unnecessary.When dirty, can add clean agent to scrub with water, clean after clean clean as before.
9. Better design of broken bridge aluminum: the composite window of broken bridge aluminum and aluminum plastic is scientifically designed and adopts reasonable energy-saving profile, so it is recognized and praised by the authority of the state and can add luster to the building.
