[China Aluminum Network] The principle of broken bridge type aluminum-plastic composite window is to use plastic profiles (more than 1250 times of heat insulation than aluminum profiles) to separate two layers of indoor and outdoor aluminum alloys and connect them tightly to form a whole. The new heat-insulating aluminum profile uses this type of profile for doors and windows. Its heat insulation is in the same grade as the plastic (steel) window, which is a national standard. It completely solves the problem that the aluminum alloy conducts heat quickly and does not meet the energy saving requirements. Problems, at the same time taking some new forms of structural cooperation, completely solved the "aluminum sliding window is not strict" the old hard problem. The product is made of aluminum on both sides, with a plastic profile cavity as a thermal insulation material in the middle. This innovative structural design takes into account the advantages of both plastic and aluminum alloy materials, while meeting a variety of requirements for decorative effects, door and window strength, and endurance performance.
The super-bridge aluminum-aluminum plastic profile can realize the three-seal structure of the doors and windows, reasonably separate the water vapor cavity, successfully achieve the equal pressure of air and water, and significantly improve the watertightness and airtightness of doors and windows. The airtightness of this window is better than that of any aluminum or plastic window. It can ensure that there is no dust on the indoor sill and floor in areas with large sandstorms; it can ensure that residents within 50 meters on both sides of the freeway are free from noise, and its performance is close to leveling. window. This window combines the advantages of both aluminum and plastic windows, eliminating their respective disadvantages and making them ideal for users.
This window is currently priced at 360-400 yuan / square meters, although slightly higher than the current market, ordinary aluminum, plastic sliding window, but the comprehensive use of this window is much better than ordinary aluminum, plastic composite window, or even Compared to the double aluminum sliding window, it has a good effect, and it has a very high cost performance. In this sense, it costs more than 35 yuan to spend, and the use of this window can save heating costs and air conditioning electricity charges by 50% for 3 years. The energy-saving cost is enough to make up for the previous investment.
