The doors and windows of the house have to withstand tens of thousands of times of switching, which requires doors and windows to withstand the test of tens of thousands of times. Aluminum alloy doors and windows and plastic steel doors and windows are able to bear such a heavy burden of doors and windows, then aluminum alloy doors and windows and plastic steel doors and windows which is better to use, the price sex ratio is higher?

 Famous brand of doors and windows: comparison of aluminum alloy doors and windows with plastic steel doors and windows

Thermal insulation performance: thermal insulation is a standard to measure the door, indoor heating, air conditioning and other requirements on the door insulation is very high. The thermal insulation performance of aluminum alloy doors and windows is not as good as that of plastic steel doors and windows.

Daylighting performance: the lighting performance of plastic steel doors and windows is worse than that of aluminum alloy doors and windows, and the shading area of its frame and fan components is about 10% larger than that of aluminum alloy doors and windows. The vision and decoration effect are poor. It is not conducive to building lighting energy conservation and consumption reduction to rely on lighting to supplement indoor light shortage.

Sound insulation performance: the gap sealing level of aluminum alloy doors and windows is basically the same as that of plastic steel doors and windows. Under the same glass thickness, structure and sealing condition, the weighted sound insulation loss RW values of plastic steel doors and windows and aluminum alloy doors and windows are similar.

Fire resistance: the fire resistance of flame retardant PVC plastic doors and windows is better than that of combustible wood doors and windows, but it is poor compared with non combustible aluminum alloy doors and windows. Plastic doors and windows emit toxic gases such as hclcoco2 when burning. Therefore, some European countries stipulate that PVC doors and windows are not allowed to be used in public buildings. Compared with steel doors and windows, aluminum doors and windows are relatively good, and plastic doors and windows and wooden doors and windows are relatively poor.

Decoration: color decoration is very important to the effect of architectural art. Plastic steel doors and windows, as external windows, can only be white. Color decoration is very important to architectural art effect. The heat resistance and weather resistance of colored PVC profiles are greatly reduced, so they can only be used indoors. Relatively speaking, aluminum alloy doors and windows have a wide range of surface colors, including white, green and other colors, wood grain, granite and other surface colors.

Aging problem: aluminum alloy profiles are durable, there is no aging problem, and PVC plastic profiles do age. After 1500 hours of irradiation, the color of PVC plastics turns yellow obviously, and PVC plastics are easy to be polluted and dirty, which is not easy to clean, and accelerates its aging speed.

Performance / price ratio: the cost performance ratio of aluminum alloy doors and windows is higher than that of plastic steel doors and windows. The price of aluminum alloy doors and windows is 1.5 times that of plastic steel doors and windows, that is, the price of plastic steel doors and windows is 33% cheaper than that of aluminum doors and windows. However, aluminum alloy doors and windows are far better than plastic steel doors and windows in terms of high strength, high performance, excellent corrosion resistance (spray paint), decorative effect and long service life.
