Doors and windows, as an important part of the external structure of the building, not only meet the basic requirements of people's lighting, ventilation, vision, but also have excellent insulation, heat insulation, sound insulation performance, in order to provide people with a comfortable and tranquil indoor environment, to meet people increasingly Improve the quality of life requirements. In 2001, China entered an all-round construction of a well-to-do society. The design, development, and construction of satellite cities and towns have been carried out throughout the country and the market has grown rapidly. The country has a city area of ​​6.255 billion square meters and a rural residential area of ​​34.575 billion square meters. The good development of the construction industry has also promoted the overall development of the doors and windows industry.
Aluminum alloy doors and windows have become China's major architectural doors and windows due to their light weight, high strength, good performance, strong decorative, economical and durable, and non-polluting ability to be recycled and reused. They are widely used in high-end public buildings and general civil residential and industrial plants. . In recent years, the Ministry of Construction has put forward specific requirements for building energy conservation. Common aluminum alloy doors and windows have been severely impacted because of poor energy saving effect. Fortunately, aluminum alloy profile manufacturers in China have been working on the research and development of heat insulation aluminum profiles. Over the past five years, There are more than a dozen manufacturers have produced a variety of heat insulation aluminum alloy profiles, completely solve the shortcomings of ordinary aluminum alloy doors and windows are not energy-efficient, to give aluminum alloy doors and windows regain market productivity, until last year, aluminum alloy doors and windows market share still Can maintain a 55% share, insulated aluminum doors and windows are gradually replacing ordinary aluminum alloy doors and windows products. China's earlier development of the broken aluminum alloy insulation doors and windows of the company Beijing Aluminium Co., Ltd. from the 1997 sales ratio of the two products to see, in 1997 ordinary aluminum alloy sales accounted for 95% of total sales, insulation aluminum alloy doors and windows accounted for 5% By 1999, sales of ordinary aluminum alloys were 68%, and insulation aluminum alloy doors and windows accounted for 32%; in 2001, sales of ordinary aluminum alloy doors and windows were only 11%, and insulation aluminum alloy doors and windows accounted for 89%. Aluminum alloy doors and windows were successfully completed. The product is converted into high quality insulation aluminum alloy doors and windows products.
According to market requirements, efforts to develop new products is a road that Beijing Aluminium has been actively developing. In order to meet the requirements of the market and the national building energy conservation in 1997, according to the requirements of the implementation of the “Energy Conservation Law†by the State, the organization of technical personnel research and development has succeeded in energy saving and heat insulation aluminum profiles with environmental protection, and will PU high hardness, high density resin and The combination of aluminum profiles has opened up a new path for energy saving in China's architectural aluminum profiles. It is hailed by experts as “a revolution in aluminum doors and windowsâ€, and the energy-saving effect can reach over 40%. Its price is only for foreign similar products. 50% were granted four patent rights by the state and have been used in projects such as the State Planning Commission Scientific Research Building, Fangzhuang Ancient Garden Phase II, the Red Sandals Palace, and the Peking University Tsinghua Blue Land Camp Residence. The Ministry of Construction has been designated as the “Key Technology Achievement Promotion Productâ€. It has passed the scientific and technological achievements appraisal organized by the Beijing Municipal Committee on Urban and Rural Development and won the second prize of the Beijing Science and Technology Achievement Award. It has become a competitive product in the market competition and was first developed in Beijing in 1999. The patented aluminum alloy radiators, in the two years 2000-2001, also disconnected and sent out embedded insulation aluminum profiles, cast-in-place insulation aluminum profiles and copper-aluminum composite radiators, and injected new products for the company's products in the market competition. vitality.
In 2001, after the introduction of new products embedded aluminum heat insulation aluminum profiles in the industry, in a short period of time within a short period of time, have developed a series of open windows and open windows, in October in response to the requirements of our customers, the successful development The embedded type 63 series inside and outside doors, 90 series embedded sliding windows, and passed the inspection of national construction engineering quality supervision and inspection. 63 Hollow series thermal insulation coefficient K value is 3.08W/square meter*k, which belongs to national standard level 3, physical three-characterity detection is national standard 1.2.2 grade. 63LOW-E hollow series thermal insulation coefficient K value of 2.42W / square meter × K is a national standard two, physical three-state detection for the country?
