Broken bridge aluminum alloy doors and windows and UPVC Profile doors and windows are two kinds of door and window materials that people often choose, so often some friends do not know how to choose the door and window material. UPVC Profile manufacturers compare the differences between broken bridge aluminum alloy doors and windows and UPVC Profile doors and windows from several aspects, so that you can choose the right doors and windows.
1. Wind pressure strength and water tightness
Due to the low material strength and rigidity of UPVC Profile doors and windows, although they are reinforced by adding linings, their wind pressure resistance and water tightness are about two grades lower than those of aluminum alloy doors and windows. Moreover, since the lining steel of UPVC Profile doors and windows is not connected to form a complete frame system at the corners of the inner cavity of the profile, the plastic welding corner strength of the window frame, the four corners of the sash and the t-bit point is relatively low.
2. Air tightness performance
Since the frame and fan components of UPVC Profile doors and windows are welded, the air tightness should be slightly better than that of screw-connected aluminum alloy doors and windows. on a hierarchical level.
3. Thermal insulation performance
The thermal insulation performance of broken bridge aluminum alloy is not as good as that of UPVC Profile doors and windows.
4. Lighting performance
The lighting performance of UPVC Profile doors and windows is worse than that of aluminum alloy doors and windows. The shading area of its frame and fan components is about 10% larger than that of aluminum alloy doors and windows. The visual field and decorative effect are poor, which is not conducive to energy saving and consumption reduction of architectural lighting.
5. Sound insulation performance
The sound insulation performance of the window mainly lies in the sound insulation effect of the glass which accounts for about 80% of the window area. The gap sealing level of broken bridge aluminum alloy doors and windows and UPVC Profile doors and windows is basically the same, and their sound insulation performance is basically the same.
6. Fire resistance
Regarding the fire performance of doors and windows: steel doors and windows and aluminum doors and windows are relatively good, plastic doors and windows and wooden doors and windows are relatively poor.
7. About lightning protection and static electricity
Broken bridge aluminum alloy is a good conductor, so when it is used as a building peripheral structure, effective grounding measures are used, which can be used as a lightning protection facility and can prevent the occurrence of static electricity; pvc plastic is a non-conductive insulator, when it is used in high-rise buildings. (The first type of lightning protection building is more than 30m, the second type is more than 45m, and the third type is more than 60m), and the side lightning strike problem cannot be solved.
Eight, decorative
As the exterior windows of buildings, plastic doors and windows can only be dominated by white. Because white or light gray pvc profiles have better weather resistance and light stability, and are not easy to absorb heat. The heat resistance and weather resistance of colored pvc profiles are greatly reduced, and they can only be used indoors. Color decoration is very important to the effect of architectural art. The single white color of plastic doors and windows is a huge defect, which cannot meet the needs of various kinds of building exterior wall decoration. Relatively speaking, broken bridge aluminum alloy doors and windows have a variety of surface treatment technologies such as powder spraying, anodizing, electrophoresis coating, wood grain transfer treatment, etc. The surface color has a large choice of white, green and other colors and wood grain. , granite and other surface colors.
The differences and differences between broken bridge aluminum alloy doors and windows and UPVC Profile doors and windows have been introduced to you.
