The main body of the heat-insulating aluminum alloy is made of aluminum, and a plastic profile cavity is used as the heat-insulating material in the middle of the profile. This innovative structural design takes into account the advantages of plastic and aluminum alloy materials, while meeting various requirements for decorative effect, strength and aging resistance of doors and windows. The thermally insulated broken bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of air and water, and significantly improve the water and air tightness of doors and windows. The air tightness of insulated aluminum doors and windows is better than that of any aluminum or plastic windows. It can ensure that indoor window sills and floors in areas with strong wind and sand are dust-free; it can ensure that residents 50 meters on both sides of the highway are not disturbed by noise; and the thermal conductivity is better than Non-insulated aluminum alloy doors and windows reduce the cost by 40 to 70%.
