Aluminum alloy window is a window with frame-sash structure made of aluminum alloy building profiles, which is divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. Aluminum alloy windows are beautiful, sealed and high in strength, and are widely used in the field of building engineering. In home decoration, aluminum alloy doors and windows are often used to encapsulate balconies.
The surface of aluminum alloy is bright and shiny after oxidation. The frame is large and can be inlaid with a large area of glass, which makes the indoor light bright enough, enhances the contrast between indoor and outdoor facades, and makes the room more layered. Aluminum alloy itself is easy to be extruded, and the section size of the profile is accurate and the processing accuracy is high, so many owners choose to use aluminum alloy doors and windows in decoration.
Development history
In the late 1980s, doors and windows were all aluminum alloy windows, and aluminum alloy profiles were used. Although some shortcomings of steel window are solved, the profile itself is made of metal, which has fast cold and heat conduction. The whole window K value of steel window and aluminum alloy window is above 6.0W/(m2 k), which does not fundamentally solve the problem of sealing and heat preservation. Although insulating glass can be installed, the K value of the whole window can only reach about 4.5 W/(m2 k).
Broken bridge aluminum alloy insulation doors and windows appeared in the door and window market in the middle and late 1990 s, which was a high-grade door and window product in the door and window market at that time. The middle of the profile design is made of high-strength insulating synthetic materials, and the surface treatment is made of powder spraying, fluorocarbon spraying, resin hot stamping and other high technologies. Can meet the ever-changing color matching needs.
The outstanding advantages of broken bridge aluminum alloy heat insulation doors and windows are light weight, high strength, good water tightness and air tightness, good fire resistance, large lighting area, atmospheric corrosion resistance, long service life, good decorative effect and good environmental protection performance.
However, with the improvement of people's quality of life, more and more attention is paid to health, environmental protection and energy saving. Heat-insulated aluminum alloy windows and plastic steel windows do not match the interior decoration, which can not satisfy the appreciation of modern people, and do not conform to the national energy-saving climate.
