1. Comparison of sound insulation performance of aluminum alloy windows and uPVC windows: The gap sealing level of aluminum alloy windows and uPVC windows is basically the same, and the sound insulation performance of aluminum alloy windows is basically the same.
2. Comparison of wind pressure strength and water tightness between aluminum alloy windows and uPVC windows: uPVC windows have low material strength and rigidity. Although they are reinforced by processing lining steel, the wind pressure resistance and water tightness of uPVC windows are about two lower than those of aluminum windows. grade.Plastic windows should be used with caution in high-rise buildings
3. Comparison of thermal insulation performance of aluminum alloy windows and uPVC windows: the thermal insulation performance of aluminum alloy windows is not as good as that of uPVC windows, but the ratio of the heat transfer coefficient of aluminum alloy windows to uPVC windows is only 1.36 times (single-layer windows) and 1.44 times ( Single frame double glass window)
4. Comparison of air tightness between aluminum alloy windows and uPVC windows: Because the frame and fan components of uPVC windows are welded, the air tightness of uPVC windows should be slightly better than that of screwed aluminum alloy windows, but the dimensional accuracy of aluminum alloy window profiles is relatively high. High, the frame and fan are closely matched, so the aluminum alloy window and the uPVC window are still on the same level.
5. Comparison of lighting performance between aluminum alloy windows and plastic steel windows: the lighting performance of plastic steel windows is worse than that of aluminum windows, and the shading area of a single component of plastic steel window frames is about 10% larger than that of aluminum windows.
