Aluminum alloy doors and windows are upgraded with plastic steel doors and windows. Aluminum alloy doors and windows are widely used indoors, beautiful and durable, and the price is high. There are also the following features.
Comprehensive analysis of performance characteristics of aluminium windows and plastic steel windows
1. Wind pressure resistance and water tightness:
Due to the low material strength and rigidity of plastic-steel window, although it has been processed and lined steel enhanced, its wind pressure resistance and water tightness are about two grades lower than that of aluminum window. Moreover, because the lined steel of the plastic steel window is not connected into a complete frame system in the corner of the inner cavity of the profile, the plastic welding angle strength of the window frame, the four corners of the fan and the T-shaped node is relatively low, according to the analysis of the three performance examples of 425 batches of plastic-steel windows submitted by Shanghai enterprises at the end of 1998, it is seriously pointed out that "instrument frame should be used carefully in high-rise buildings."
2. Air tightness:
Since the frame and fan components of the plastic-steel window are welded, the air tightness of the plastic-steel window should be slightly better than that of the threaded aluminium windows, but the size accuracy of the aluminum window profile is higher, and the frame and fan are closely matched, so the two are still at the same level.
3. Thermal insulation performance: the thermal insulation performance of aluminum window is not as good as that of plastic steel windows, but the ratio of the heat transfer coefficient of the two whole windows is only 1.36 times (single window) and 1.44 times (single frame double glass window).
4. Lighting performance:
The lighting performance of plastic-steel windows is worse than that of aluminum window, and the shading area of single frame component is about 10% larger than that of aluminum window. The visual field and decorative effect are poor, which is not conducive to energy saving and consumption reduction of building lighting.
5. Sound insulation performance:
Aluminum window is basically the same as the gap sealing level of plastic steel windows, and its sound insulation performance is also basically the same.
6. Fire prevention performance:
The fire performance of flame retardant PVC plastic steel windows is better than that of combustible wooden window, but it is worse than that of non-combustible aluminium windows.
7. Lightning protection and static electricity problems:
Aluminum Alloy is a good conductor, so when it is used as a building periphery structure-enclosure construction, effective grounding measures can be taken as device against thunder bolt and static electricity can be prevented.
8. Decorative:
As the exterior windows of buildings, plastic-steel windows can only be mainly white, which cannot meet the needs of various kinds of building exterior wall decoration.
9. Aging problems:
PVC plastic profiles will age. Under the action of ultraviolet rays, macromolecular chains of polymer PVC resin break, which makes the surface of the material lose luster, change color and powder, and the mechanical properties of the profiles decrease. While aluminum alloy has anti-aging function.
10. Deformation and expansion:
Plastic-steel windows are easy to deform when heated, become brittle when cold, and have poor stability in size and shape. It is often necessary to use the rigidity of glass to prevent the window frame from deforming. However, aluminum alloy has the advantages of high temperature resistance and not easy to deform.
Introduction:
1. Advantages and characteristics of insulated aluminum profiles.
2. Excellent energy saving effect. K. Value 2.0-3.0W/M2K. Energy saving 30%-40%
3. Excellent sound insulation performance, reducing noise 30-50dB
4. Anti-condensation Hydra Zen cream function, clean and bright windows.
5. High strength, resistance to wind can reach level 1 standard.
6. Good air tightness and watertightness, all of which meet the level 1 standard,.
7. Three-chamber design principle. High structural stability and excellent mechanical properties.
Middle seal design. Double seal effect.
8. It is produced by European advanced double threading Institute. It has the characteristics of complete structure, firm combination, good rigidity, large thermal resistance, etc. Compared with the existing single-injection adhesive strip insulated aluminum profile. Better heat insulation effect.
9. Insulation aluminum alloy profiles are anodized. Electrophoresis painting and powder spraying. Rich variety. Excellent:; Three properties, ideal energy saving and sound insulation effect, can be called the essence of modern door and window materials.
