Relevant data show that China is the largest market for doors and windows in the world. In addition to traditional aluminum alloy doors and windows, the development of plastic doors and windows is also in full swing. According to the current market share of plastic doors and windows, there are about 175 million square meters of plastic doors and windows construction tasks every year.However, China's plastic doors and windows industry is very large, but its output value is not high. There are three main reasons for this.

Consumption concepts need to be changed

At present, when Chinese buyers buy a house, they mainly pay attention to the qualifications of developers and builders, as well as the construction quality of the house. Buyers of doors and windows pay less attention.On the one hand, it is due to people's lack of knowledge about doors and windows, on the other hand, they always believe that doors and windows are accessories to the house in terms of concept, and their quality has little effect.But abroad, there is a popular saying: Whether the housing is good or bad, the key depends on the doors and windows.

Buyers in the United States often require what kind of doors and windows, what materials, and what standards are used by builders.For commercial housing with a price of 10,000 yuan per square meter, the price of supporting doors and windows is generally about 1,000 yuan per square meter abroad, while in my country it is only about 300 yuan per square meter.This shows that the quality and level of doors and windows in our country are generally low.

Vicious competition is serious

Because plastic doors and windows have many incomparable advantages of other materials, our country lists plastic doors and windows as one of the key national development building materials.Therefore, in the past 10 years, the production and application of plastic doors and windows in our country have achieved rapid development, but due to overheating development, the status quo of serious oversupply has been caused.

At present, the annual market demand for plastic doors and windows in our country is about 1.5 million tons, while the annual production capacity of plastic doors and windows has reached 3 million tons. The consequence of oversupply is that the industry has serious vicious competition at low prices, and products are shoddy and cut corners occur frequently, which has greatly affected the reputation of plastic doors and windows.The consequences of low-price competition have also caused the entire plastic door and window industry in our country to be at a loss.

Du Zonghan said that although the current market share of plastic doors and windows in our country is quite large, there is still a certain gap compared with developed countries abroad.According to statistics, the current average market share of plastic doors and windows in Europe is 40%, the market share of plastic doors and windows in Germany has reached 54%, and the United States has reached 45%.In terms of building energy consumption, the total unit energy consumption of residential buildings in our country is about 3 times that of developed countries, the energy consumption of outer windows is 1.5 to 2.2 times that of developed countries, and the air leakage rate of doors and windows is 3 to 6 times that of developed countries.This shows that the gap between the energy-saving level of our country's buildings and that of developed countries abroad is still large.

Industry standards are disorganized

According to President Du's introduction, at present, our country does not have an industry standard for doors and windows that matches the price of houses, and usually the requirements for the five major properties of doors and windows, namely wind pressure resistance, air leakage performance, rainwater penetration performance, thermal insulation performance, and sound insulation performance, are often only the samples sent for inspection can be qualified, and the pass rate for rear door and window testing is low when the house is built.
