As a big consuming country of energy, with the development of economy, energy consumption and utilization efficiency are low, and energy resources constraint is becoming more and more serious. Energy demand pressure is more and more urgent to be solved and improved. Data show that by the end of 2015, the proportion of building energy consumption in the total energy consumption has risen to 27.45%, while China's current construction of more than 97% of high energy buildings. The energy consumption of doors and windows occupies 45%~50% of the building energy consumption in the total energy consumption, accounting for 20% of the total energy consumption of the society, and the doors and windows become the weakest link of the building energy efficiency in our country. In such a huge energy consumption, energy-saving door and window industry rising. The following is the analysis of the present situation of 2017 energy-saving doors and windows industry building materials network consolidation.

 

At present, China's energy-saving door and window industry presents three characteristics:

 

1, energy-saving doors and windows industry scale continues to expand

 

After entering twenty-first Century, the annual demand of doors and windows in our country is nearly 500 million square meters. At the same time, the state government departments have repeatedly introduced new policies for building energy conservation, the provinces, municipalities and autonomous regions have also formulated the local building energy efficiency design standards. In this case, the building door and window industry has accelerated the pace of scientific and technological innovation, product upgrading, quality improvement, and launched a large number of new environmentally friendly energy-saving products to the community, so that the industry has been an unprecedented development.

 

It is understood that the design of energy-efficient buildings around the doors and windows products ratio of about 50%. It is reported that, due to energy-saving doors and windows products technical content higher than ordinary products, the national quality inspection departments of the supervision and inspection efforts, the larger "Street shop" and "guerrillas" do not follow the good and other reasons, led to the current energy-saving doors and windows products added value is much higher than ordinary products. Generally qualified energy-saving door and window products profit margins of about 12%-15%, compared with the profit margin of less than 5% of traditional door and window products, energy-saving doors and windows are obviously more favored by enterprises. Therefore, in recent years, many manufacturers and door and window curtain wall enterprises with certain strength have joined the energy-saving door and window industry to enlarge the scale of the industry.

 

2, energy-saving door and window industry backbone has been formed

 

It is understood that a few years ago, China's construction doors and windows industry in a small scale, technical equipment times, product quality is low. For energy-saving doors and windows market, with engineering, investment characteristics of the large amount of funds, the enterprise has relatively high ability of design, exquisite processing technology and mature construction technology for small scale enterprises, the formation of the capital barrier. And large-scale backbone enterprises with their strong strength, good reputation advantages, quickly occupied a large number of markets, scale advantages highlighted. Such as Shenyang's "ambitious" and Beijing's "Jiayu", "Shenzhen Guangdong" door window and curtain wall manufacturers, with its windows production, construction in the field of technological innovation and market development ability, has become the backbone of the region within the industry.

 

According to the survey, Beijing City metal doors and windows industry association in 2006, Beijing engaged in the production and processing of building doors and windows enterprises around 500, PVC plastic doors and windows, doors and windows products Aluminum Alloy annual production capacity of 20 million square meters, the output value reached 3 billion yuan, of which the output of products reach 50 thousand square metres of the 58 enterprises, more than 100 thousand square meters of enterprises 20, 300 thousand square meters of more than 3 enterprises. 2006 Jiayu company doors and windows production reached 400 thousand square meters, was named Beijing Construction Industry Association of Beijing metal doors and windows doors and windows 10 companies first. It is estimated that in 2007 the output of doors and windows will reach 500 thousand square meters, becoming the regional industry's real leading enterprises.

 

The behavior of these enterprises not only effectively promoted the implementation of the national building energy conservation policy, but also played a "escort role" for the healthy and rapid development of the industry.

 

3, energy-saving doors and windows industry innovation products great potential

 

It is understood that although China's energy-saving doors and windows industry has been considerable development, but compared with the market demand, there are still some problems, the main form has two aspects: one is the all-weather products, two is the cost problem. All-weather which is able to adapt to the requirements of China's vast expanse of doors and windows products in different climatic conditions, summer heat insulation, can meet the requirements of the northern winter, but also can reach the southern coastal areas of anti seawater corrosion and anti sunlight standard. Cost performance problem is how to let more new energy-saving door and window products into the current still living in the old house of ordinary people home.

 

In order to solve these problems, some domestic manufacturers have taken the lead. Beijing fangyunsheng fiberglass Co., under the assistance of experts in the industry, developed can meet the climate conditions in the coastal areas of Guangdong, and can adapt to the demand of energy-saving doors and windows of new composite materials, such as the Xinjiang alpine region of Liaoning. The factory is going all-out to cooperate with the implementation of building energy-saving pilot work in Hainan Province, once the "Fang Yunsheng" doors withstood the Hainan typhoon and seawater corrosion test, the product of this factory will be Everfount into Hainan.

 

And as the development of Beijing Jiayu company Aluminum Alloy energy-saving window system, has passed the expert appraisal of the Ministry of construction technology development center, its technical level has reached the international advanced level in the same period. The cavity design and connection material unique, using common raw materials to produce the heat preservation performance index K value can reach 9 2.3-2. "Jiayu" brand energy-saving doors and windows, the retail price of about 800 yuan / square meters, the price is in the forefront in the industry, therefore, Chinese Building Decoration Association and other specialized associations issued a document, "Jiayu" recommended products to the various construction units in Beijing city.
