State "Eleventh Five-Year Plan" The introduction of plastic doors and windows to allow enterprises Hi on the brow Tomicus as explicitly set forth the plan to reduce energy consumption 20% of the national goal of reducing energy consumption of building energy conservation has become an important measure, and the plastic doors and windows is the state's key chemical building materials to promote energy conservation. But the question is whether the plastic door and window industry policy to seize this opportunity and realize the whole industry by leaps and bounds.
       Last year, China's plastic doors and windows in cities and towns in the new residential market share has reached 55%. Although the proportion of high, but in fact than the decline in 3 years ago, especially in the southern market, the market share of plastic doors and windows fell more new cities and towns in China in more than 70% of residential use of plastic doors and windows.
      2000 before and after the rise of plastic doors and windows, in the short term with good insulation, and corrosion, and diverted a lot of the traditional market of aluminum alloy doors and windows, aluminum alloy doors and windows can be said was almost forced out of major cities in new residential market. But over the past 2012 years, aluminum alloy doors and windows to increase research into the industry, the new thermal insulation properties of high-grade alloy bridge windows, decorated in good color of aluminum alloy doors and windows, good insulation properties of the aluminum decorative wooden doors and windows and other new products, aluminum alloy doors and windows so that the competitiveness has improved significantly, began to be able to grab the market with plastic doors and windows.
       On the other hand, plastic doors and windows are also long-term overcapacity, low-quality competition, slow new product development consequences. As a result of overheated investment, plastic door and window industry since 2003 there have been serious overcapacity, fierce competition to make the whole industry into a price war quagmire, leading to the quality of plastic doors and windows is very prominent, and seriously affect the competitiveness of the industry, and long-term price war is more a direct result of the slow new product development.
       Reference plastic door and window industry mature countries such as Germany, the pattern of the plastic door and window industry in general is more than a dozen large-scale enterprises and medium-sized businesses around 1000, large scale enterprises, a high degree of automation and to occupy the main market, medium-sized technology - a single species with a high level to win.
