In the early 1980s, due to its unique advantages of corrosion-resistant aluminum doors and windows, it was gradually favored by consumers in China. However, the rapid development of plastic steel doors and windows in China in recent two years has caused obvious impact on the market of aluminum alloy doors and windows.
Some people think that the thermal conductivity of aluminum door and window frame is strong, which is unfavorable to heat insulation, while plastic insulation can save energy. In view of this view, the relevant experts of aluminum products committee of China Building Decoration Association believe that in fact, the heat insulation is mainly glass, not the window frame material.
Shanghai liefan decoration materials Co., Ltd.: what are the advantages and disadvantages of aluminum alloy doors and windows?
The advantages of aluminum alloy doors and windows are good weather resistance and aging resistance. Its heat insulation material, however, is not as good as the other two materials. The advantages of plastic steel windows are good sound insulation, heat insulation, fire resistance, air tightness, water tightness, corrosion resistance, heat preservation, etc. However, after all, it is PVC plastic profile, after a long time, the surface will turn yellow, the window deformation, then the service life is 20-30 years.
Why are plastic steel windows generally used in low rise residential buildings?
All along, plastic steel windows are generally used in low rise residential buildings. This is because, on the one hand, the plastic has aging, cracking and other problems; on the other hand, because of the gap between the plastic and steel plate made in China, air and water can enter and gradually corrode the steel plate, so the strength and stiffness can not be guaranteed. So at present, many plastic window frames are not straight, often can not be pulled and it is difficult to open. On the contrary, the unique advantages of aluminum alloy have long been recognized by the world, which can be used to make multi-functional doors and windows with complex cross-sections. The service life can be more than 50 years or even longer. It is difficult to replace ordinary materials, especially plastic steel doors and windows.
What are the main factors that make plastic steel windows popular?
Most people can accept that the cost performance ratio of plastic steel window is the main factor of its hot sale; bridge breaking alloy is a new material which appears in recent years, and its many properties can be compared with plastic steel, and it is more durable than plastic steel, and the price is generally in 400-1200 yuan / m2, generally used for villas, high-end sunshine rooms, etc.; only a few people catch up with the trend to use frameless window products, and the price of frameless windows is generally between 360-700 yuan / m2.
Plastic steel doors and windows, as a new type of building products, have sprung up in the door and window Market in the past two years. The market share of plastic steel doors and windows is much higher than that of ordinary wood, steel doors and windows, color plate doors and windows, and is close to aluminum alloy doors and windows. More information shows that the next century will be the world of plastic steel doors and windows, then, aluminum alloy doors and windows will retreat into a corner, into the ranks of being eliminated. So, which one is better, plastic steel doors and windows or aluminum alloy doors and windows? Please pay attention to the news of Shanghai liefan decoration materials Co., Ltd., and we will make corresponding explanations for you in the future.
