Opposing Market Opportunity: Plastic Window Returns to First-tier Cities

Opposing Market Opportunity: Plastic Window Returns to First-tier Cities

In the downturn of the property market in 2014, Hangzhou's residential buildings, famous for their quality, have quietly become a choice for many developers in the retrograde market. They have used plastic windows in window and door materials (hereinafter referred to as “plastic windows”). However, in the view of Yan Leiguang, director of the Plastic Doors and Windows Committee of the China Construction Metal Structure Association, this is not the return of industry value.

"From the ever-increasing trend of building energy-saving standards, plastic windows still have good prospects for development." Yan Leiguang told the China Real Estate News reporter that plastic windows have obvious cost-effectiveness in building insulation.

It is not the return of value back in 2006 and 2007. Plastic windows have basically exited the Hangzhou market. Commercial housing projects generally use aluminum alloy windows, and individual high-end villa projects use aluminum-wood composite windows. Analysis of the local industry, is still using plastic windows is the lower grade of real estate or for the need to control costs. Under normal circumstances, using the same plastic window, in terms of material costs, compared to aluminum alloy windows can save half.

According to information provided by the Plastics and Windows Committee of the China Construction Metal Structure Association, the market share of plastic windows in the national window and door market has reached over 40%. Yan Leiguang said: “The proportion of plastic windows north of the Yangtze River is higher than that of the south of the Yangtze River. The requirements for building insulation in the Jiangnan region are not very high. The utilization rate of plastic windows is north of the Yangtze River, especially in the northeast, north and northwest regions. More than 70% of Harbin's usage rate may be above 90%.” Plastic windows occupy an absolute advantage in terms of sound insulation and thermal insulation. In the same price range, the overall performance of plastic doors and windows can be reached in terms of configuration, performance and function. good.

However, domestically-used plastic windows generally suffer from serious problems such as cutting corners and materials, and are difficult to maintain on a long-term basis. In addition, they have poor environmental performance and are considered to be middle- and low-end products. In addition, the plastic window is weaker than the aluminum alloy window in the lighting, corrosion resistance, watertightness, etc., and the wind pressure performance is also not significant.

Yan Leiguang believes that it is not a good thing for developers to control the cost of plastic windows, although some companies will be complacent, “but not a very good return, just feel cheap”.

The image of the industry is to be remodeled “In Europe and the United States, no one has said that the use of plastic windows will reduce the quality of life.” Yan Leiguang said, “It is the plastic window industry that is doing its own bad.” In the 1990s, the global energy crisis broke out. Energy conservation is highly valued. Plastic windows have been widely promoted by the government because of their unique thermal insulation properties. Plastic window applications have entered a stage of rapid development. Affected by this, in 1999 the output of aluminum alloy doors and windows was only half of 1995.

However, in the follow-up development, plastic window has overemphasized the ability to adapt to market consumption, reduce the cost, adulteration, and fraud, coupled with the immature design and production technology, lack of experience, and some problems in the project, these adverse effects lead to late promotion and application difficult.

In the memory of Ma Junqing, Chairman of Beijing Milano Window Energy Saving Building Materials Co., Ltd., the market share of plastic windows in Beijing was very high in 2000, but since then, the performance advantages of thermal insulation such as cracking and deformation have been cruel. Lost in the market competition, people began to produce a sense of disapproval."

Ma Junqing said that the plastic window has the highest market share in developed countries in Europe and America. China Real Estate News reporter from the Chinese Association of Architectural Metal Structures Plastic Doors and Windows Committee obtained in 2013 foreign heat transfer coefficient requirements for windows and doors and plastic window market share shows: Germany is 1.0W / (m2 · K), plastic doors and windows accounted for 65%; France is 1.6W/(m2·K), plastic doors and windows account for 56%; Britain is 1.4W/(m2·K), plastic doors and windows account for 60%; Russia is 1.4~1.8W/(m2·K), plastic doors and windows account for 70%; Korea is 1.0~1.4W/(m2·K), plastic doors and windows account for 62%; American plastic doors and windows account for 64%.

Yan Leiguang explained that the threshold of door and window technology is low, and those who have the investment ability dare to go to the production of plastic windows. The market has far exceeded supply, and some companies have taken a certain share in the market, the price has dropped to a certain extent, and fraud has appeared.

Counterattack broken bridge aluminum window?

However, in the past year or two, local governments have gradually upgraded the requirements for building energy efficiency, and the attitude of domestic developers has also changed. “In 2013, there was such a trend that market applications were returning to plastic windows from broken aluminum windows. The properties of plastic windows met the requirements for building energy conservation. Large real estate developers also began to use plastic windows, including Wanda, Vanke, and the coastal area. Pan Hai.” An aluminum alloy window business personage introduction.

“There is a residential project in Shanghai that requires the heat transfer coefficient of doors and windows to be less than 2.0 W/(m2·K). A company that owns a wholly-owned plastic window in China, the sample window is approximately 700 RMB per square meter, and several aluminum alloy windows in Shanghai are bidding. The quotation is about 1,300 yuan per square meter. In this way, plastic window is selected." Yan Leiguang said that with the continuous improvement of building energy efficiency standards, the price difference between the two is greater. The director of the Aluminum Doors and Windows Curtain Wall Committee of China Construction Metal Structure Association also recognized the thermal insulation performance of plastic windows. “The energy saving effect of plastic windows is better. There is no doubt about this. Afterwards, the energy efficiency standards for buildings have been raised. The insulation performance of windows has also been correspondingly improved. The advantages of plastic windows have become larger, and aluminum windows have reached the same energy efficiency indicators. The cost is a bit higher," Huang Xi said.

Taking 75% of Beijing's building energy efficiency as an example, the standard requires that the external window k is 1.5~2.0W/(m2·K). According to the standard window-to-wall ratio and window orientation, the k value of most exterior windows should be below 1.8 W/(m2·K) to meet the requirements. It is easy for the plastic window to have a k value of 2.0 W/(m2·K) or less, and the price is much lower than that of broken aluminum windows. In accordance with the window to achieve the same k value to calculate the price of plastic window and broken aluminum window, the price of aluminum alloy window is 1.5 times of the plastic window price, and the smaller the k value of the whole window, the greater the price difference between the two windows.

Plastic window technology is also developing. The industry has developed three sealed plastic casement windows with 65mm, 70mm, 82mm, 88mm, and 86mm series with four-cavity and above structure that are more excellent in insulation, sound insulation, watertightness, airtightness, and strength. , Texture has a better decorative effect.

“Nuremberg, Germany, hosts a world-scale door and window exhibition every two years, with an exhibition area of ​​more than 100,000 square meters. In the past, aluminum windows and plastic windows were equally divided. This year, we were also visited by people, almost all of which were plastic doors and windows. See Less than aluminum alloy doors and windows." Yan Leiguang told the China Real Estate News reporter, in this exhibition, plastic window exhibits are all 70mm series or more products. Among them, five-cavity or six-cavity three seal structure of plastic profiles, and even eight-cavity structure of the window frame material, the entire window K value up to 0.8W / (m2 · K) below.

However, the plastic window also faces the same problem with other types of windows: SMEs account for the vast majority, the design of doors and windows, processing and production is low, and the quality of products is not satisfactory. With the upgrading of building energy efficiency standards, plastic window can return to the first-tier cities, and from north to south, Ma Junqing believes that ultimately the industry can insist on doing a good job, "in the long run, this is an opportunity."
