The principle of the broken bridge aluminum-plastic composite window is to use plastic profiles (1250 times higher heat insulation than aluminum profiles) to separate and tightly connect the two layers of aluminum alloy indoor and outdoor into a whole, forming a new heat-insulating type Aluminum profile, using this profile to make doors and windows, its thermal insulation is at the same level as plastic (steel) windows-the national standard, which completely solves the fatal problem of aluminum alloy conduction and heat dissipation and does not meet energy-saving requirements. At the same time, it adopts some new The structural coordination form completely solves the old and difficult problem of "aluminum alloy sliding window is not tightly sealed". The product is made of aluminum on both sides, and the plastic profile cavity is used as the thermal insulation material in the middle. This innovative structural design takes into account the advantages of both plastic and aluminum alloy materials, while meeting various requirements for decorative effects, door and window strength, and aging resistance. The super-broken aluminum-plastic profile can realize the three-way sealing structure of the doors and windows, reasonably separate the water vapor cavity, and successfully achieve the equal pressure balance of air and water, and significantly improve the water and air tightness of the doors and windows. The air-tightness of this kind of window is better than any aluminum or plastic window, and it can ensure that the windowsill and floor are free from dust in areas with heavy sandstorms; it can ensure that residents within 50 meters on both sides of the expressway are not disturbed by noise, and its performance is close to flat opening. window.

This kind of window combines the advantages of aluminum and plastic windows and removes their respective shortcomings, thus becoming an ideal choice for users. The current price of this kind of window is about 360-400 yuan per square meter. Although it is slightly higher than the ordinary aluminum and plastic sliding windows on the market, the comprehensive use effect of this kind of window is much better than that of ordinary aluminum and plastic composite windows, and even It is better than double-layer aluminum sliding windows and has a very high cost performance. In this sense, it is worthwhile to spend thirty or fifty yuan more, and the use of this type of window can save heating costs and air conditioning electricity costs by 50%, 3 years The energy saving cost is enough to make up for the initial investment.

Performance and advantages:

1. Good thermal insulation: the plastic in the aluminum-plastic composite profile has low thermal conductivity, and the thermal insulation effect is 1250 times better than that of aluminum.

2. Good sound insulation: the structure is carefully designed, the seams are tight, the test results, the sound insulation is 30 db, which is in line with the relevant

3. Impact resistance: Because the outer surface of the aluminum-plastic composite profile is aluminum alloy, it is more impact resistant than the plastic-steel window profile

4. Good air-tightness: each gap of the aluminum-plastic composite window is equipped with multiple sealing tops or rubber strips, and the air-tightness is level one.

5. Good water tightness: The doors and windows are designed with rain-proof structure to completely isolate rainwater from the outdoors.

6. Good fire resistance: aluminum alloy is a metal material and does not burn.

7. Good anti-theft: aluminum-plastic composite windows, equipped with excellent hardware accessories and advanced decorative locks, make thieves helpless

8. Maintenance-free: Aluminum-plastic composite profile is not easy to be corroded by acid and alkali, will not turn yellow or fade, almost no maintenance.
