The Development History of Aluminum Alloy Windows

In the late 1980s, doors and windows were aluminum alloy windows made mainly of aluminum alloy profiles. Although they solved some of the shortcomings of steel windows, the profiles themselves were metal materials with fast heat and cold conduction. The K value of the entire window for both steel and aluminum alloy windows was above 6.0w/(m2. K), and there was no fundamental solution to sealing, insulation, and other problems. Although insulating glass could be used, the K value of the entire window could only reach around 4.5w/(m2. K).
In the mid to late 1990s, broken bridge aluminum alloy insulated doors and windows appeared in the door and window market, which were high-end door and window products at that time. High strength insulation composite materials are used in the middle of the profile design, and high-tech methods such as powder spray coating, fluorocarbon spray coating, and resin thermal printing are used for surface treatment. Can meet the ever-changing color matching needs.
The outstanding advantages of broken bridge aluminum alloy insulated doors and windows are light weight, high strength, good water and air tightness, good fire resistance, large lighting surface, resistance to atmospheric corrosion, long service life, good decorative effect, and good environmental performance.
But with the improvement of people's quality of life, there is an increasing emphasis on health, environmental protection, and energy conservation. Insulated aluminum alloy windows and plastic steel windows cannot match indoor decoration, cannot meet the aesthetic taste of modern people, and also do not conform to the national energy-saving climate.
