Characteristics of PVC windows

 Among many window decoration materials, pvc windows are very popular with community owners. However, the products on the market are mixed, some are good and some are not so good. How do we judge the quality of pvc windows? The editor of Lumei profiles will introduce to everyone the famous brands of pvc windows and the purchase methods of pvc windows, which can ensure to the greatest extent that community owners can buy good pvc windows.

   1. Pvc windows have strong process performance. In the molten state, plastic has high fluidity. Therefore, accurate cross-sectional structures can be produced through this mold to meet the functional requirements of the window. It can also form a segmented inner cavity to improve the thermal insulation, sound insulation and drainage functions of the window, and prevent the corrosion of building steel channels.

2. Pvc windows are environmentally friendly and energy-saving. Plastic windows are more environmentally friendly, energy-saving and improve the indoor thermal environment than other windows. According to experiments by the Institute of Physics, the heat transfer coefficient of single-glass reinforced plastic and aluminum windows is 64W/M2K; single-glass plastic-steel windows are The heat transfer coefficient is around 47W/M2K.

 Generally, the heat transfer coefficient of double-glazed steel and aluminum windows is about 3.7W/(m2·K); while the heat transfer coefficient of double-glass pvc windows and doors is about 2.5W/(m2·K). Windows account for 30% of the total housing area and 49% of the heating capacity. It can be seen that pvc windows have excellent environmental protection, energy saving and economic benefits.

   3. Pvc windows have good sound insulation and noise reduction. The heat insulation performance of steel aluminum windows is about 19 decibels, and the sound insulation performance of pvc windows can reach more than 30 decibels. In an increasingly noisy urban environment, the use of pvc windows can make indoor air more comfortable. According to the information provided by Japan, in order to meet the same noise reduction requirements, the distance between aluminum window buildings and main roads must be 50 meters, and the distance between plastic window buildings can be 18 meters.

According to tests conducted by the Beijing Labor Protection Research Institute, the noise in rooms using pvc windows is reduced to 32DB (A), and the actual effect is excellent. With the development trend of economic development, the problem of urban noise is becoming more and more serious. Pvc windows have a great effect on improving the acoustic environment in our daily life and work. In addition, pvc windows are corrosion-resistant and can be used in coastal areas, pharmaceutical factories and other corrosive environments.

   4. The appearance of pvc windows is good, which can meet the requirements of Chinese decorative design effect, and the body feels more comfortable than metal materials. Because of its outstanding advantages, pvc windows have been widely used in our country and have become a new development trend in the construction industry.

   5. Pvc windows are low-cost. Compared with aluminum alloy windows and doors, the cost of pvc windows that also use high efficiency is 30%-60% lower than aluminum alloy windows and doors, which is an important reason for the promotion of pvc windows.
