The principle of the断桥式铝塑复合窗 is to use plastic profiles (which have a thermal insulation property 1250 times higher than aluminum profiles) to separate and tightly connect the two layers of aluminum alloy, forming a new type of thermal insulation aluminum profile. Using this profile for doors and windows, its thermal insulation is on the same level as plastic (steel) windows—national standard level, completely solving the fatal problem of aluminum alloy's rapid heat conduction and non-compliance with energy-saving requirements. At the same time, it adopts some new structural combinations to thoroughly resolve the longstanding issue of "aluminum alloy sliding windows not sealing tightly." This product has aluminum on both sides, with a plastic profile cavity in the middle serving as thermal insulation material. This innovative structural design takes advantage of both plastic and aluminum alloy materials, while meeting various requirements for decorative effects, door and window strength, and durability. The super断桥铝塑型材 can achieve a three-seal structure for doors and windows, reasonably separating the water vapor chamber, successfully achieving gas-water equal pressure balance, significantly improving the water tightness and air tightness of the doors and windows. The air tightness of this window is better than any aluminum or plastic window, ensuring that there is no dust on indoor windowsills and floors in areas with heavy wind and sand; it guarantees that residents within 50 meters of highways are not disturbed by noise, with performance close to that of casement windows.

This window combines the advantages of both aluminum and plastic windows, eliminating their respective disadvantages, thus becoming an ideal choice for users. The current price of this window is around 360-400 yuan per square meter, which is slightly higher than the ordinary aluminum and plastic sliding windows on the market. However, the overall performance of this window is significantly better than that of ordinary aluminum and plastic composite windows, even outperforming double-layer aluminum sliding windows, offering a high cost-performance ratio. In this sense, spending an extra thirty to fifty yuan is very worthwhile, and using this window can save heating and air conditioning costs by up to 50%. The energy savings over three years can fully compensate for the initial investment.

Performance and Advantages:

1. Good thermal insulation: The plastic in the aluminum-plastic composite profile has a low thermal conductivity, providing thermal insulation 1250 times better than aluminum.

2. Good sound insulation: Its structure is carefully designed with tight seams, and test results show sound insulation of 30 dB, meeting relevant standards.

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

4. Good air tightness: Multiple sealing strips or rubber strips are installed at all gaps of the aluminum-plastic composite window, achieving first-class air tightness.

5. Good water tightness: The door and window design includes a rainwater prevention structure, completely isolating rainwater from the outdoors.

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

7. Good anti-theft properties: The aluminum-plastic composite window is equipped with high-quality hardware accessories and advanced decorative locks, making it difficult for thieves.

8. Maintenance-free: Aluminum-plastic composite profiles are not easily corroded by acids and bases, will not yellow or fade, and require almost no maintenance.
