1. Types of energy-saving glass industry
Energy-saving glass undertakes important tasks such as indoor and outdoor temperature connection, air exchange and other important tasks in the entire building. Energy-saving glass mainly includes insulating glass, heat reflective glass, laminated glass, Low-E glass, vacuum glass, etc.

Second, the production process of energy-saving glass industry
The complete deep processing process of energy-saving glass includes seven steps: slicing, edging, color glaze, tempering, lamination, coating and hollowing, of which tempering, coating and hollowing are the core processes.

3. The application and prospect of energy-saving glass in the construction industry
At present, China has become the largest producer of flat glass in the world. Data from the National Bureau of Statistics shows that China's flat glass output from January to July 2020 was 540.3442 million weight boxes, and China's flat glass output in 2019 reached 926.7 million weight boxes.

However, the pressure of overcapacity of low value-added flat glass still exists, the production capacity of medium and low-grade glass is seriously oversupplied, and the glass products with high technical content are relatively in short supply, which is difficult to meet the needs of the domestic processing glass market, and a large number of products need to be imported from abroad. , industrial integration and upgrading urgently need to be strengthened.
The upgrading and development of the glass industry will undoubtedly promote the development of energy-saving glass, and product upgrading is the only way for industrial upgrading. From the perspective of downstream demand for energy-saving glass, the construction industry is the main application field of energy-saving glass. my country is the second largest energy-consuming country in the world, with building energy consumption accounting for more than 33% of the country's total energy consumption, and the unit energy consumption level of buildings is 4% in Europe. times, 3 times that of the United States. In 2019, the construction and completion areas of real estate in my country were 8.94 billion square meters and 960 million square meters, respectively. From January to July 2020, the real estate construction and completion areas reached 8.18 billion square meters and 330 million square meters, respectively. With such a large building volume, more than 80% of the houses are high-energy-consumption buildings, and more than 90% are high-energy-consumption buildings, using non-energy-saving glass.

In recent years, the energy saving of buildings in my country has been increasing year by year. In 2018, the energy saving of new buildings in my country reached 18.3 million tons of coal equivalent (Mtce), and the energy saving of existing residential buildings was 2.38 million tons of coal equivalent (Mtce). The gap is still relatively large, and energy-saving glass companies need to seize this opportunity to expand the domestic building energy-saving glass market.

Fourth, the development target analysis of energy-saving glass
The Ministry of Housing and Urban-Rural Development and the Ministry of Science and Technology and other relevant departments have accelerated the implementation of building energy-saving standards for new houses and implemented measures that are conducive to building energy-saving. Building Evaluation Standards", a large number of energy-saving building materials are used, including energy-saving glass such as insulating glass and Low-E glass. China Construction Glass and Industrial Glass Association proposed in the "Guiding Opinions on the Development of Glass Industry "Thirteenth Five-Year Plan"" that the glass deep processing rate will further increase to more than 60% this year, and the LowE utilization rate will increase to more than 70%. It is expected that energy-saving glass will be used in the construction field in the future. penetration will continue to increase.
