In recent years, the superiority of the aluminum doors and windows curtain wall has begun to highlight, and gradually become the mainstream product of the door and window curtain wall industry. Reviewing the development of the door and window industry, it is not difficult to see that wood windows are limited by resources, and the basic trend has gone; steel windows have been significantly eliminated due to lack of function; since the advent of aluminum doors and windows, due to their characteristics of lightness, corrosion resistance and other characteristics, they have been favored by consumers; Plastic doors and windows have developed rapidly in recent years and have caused a significant impact on the market of aluminum doors and windows. At present, aluminum doors and windows and plastic doors and windows have their own advantages and disadvantages in the exterior decoration market. From the comparison of the two functions and a number of comprehensive performance, although the plastic window is slightly better than the aluminum window in the insulation performance, but most of the performance is still better than the plastic window window, performance: plastic window wind pressure strength (1500 ~ 2500Pa) is 2 levels lower than aluminum window (2500-350Pa); plastic window and aluminum window are in the same level of hermeticity (2.5-0.5m3/mh); single-layer aluminum window insulation performance (6.4w/m2k) is poor , But insulation aluminum windows (1.8w/m2k) insulation performance is much higher than the plastic window; plastic window lighting performance is worse than aluminum windows, about 10% reduction, visual field and decorative effects are not as good as aluminum windows; plastic window noise performance and aluminum Similar to the window, no big difference (single glass window 20 ~ 26dB, hollow glass window 20 ~ 26dB).
