In recent years, all kinds of new insulation board materials continue to appear, but there are not many materials that can achieve such good insulation performance as glass wool board for external walls. With the rapid development of economy and the improvement of people's living standards, the demand for room comfort is also higher and higher. In addition, it is in the key period of energy-saving urbanization development, and the demand for buildings is rising, The proportion of building energy consumption is also increasing.

　　With the rapid development of China's economy, people have higher and higher cognition of architecture, and the requirements of economic and comfort of the construction industry are also higher and higher. After the concept of green building was put forward, new building materials emerged. The new building materials include wall material, heat preservation material, waterproof material and glass wool decoration material.

　　Glass wool plays an important role in the heat preservation material industry because of its advantages of good molding, small volume density, low thermal conductivity, heat insulation, sound absorption and corrosion resistance. With the continuous and stable development of China's national economy, the application field and market of glass wool are also expanding, and the production capacity has been further improved. It is mainly used in steel structure industrial buildings and public buildings, and the consumption of civil buildings is very small. It is predicted that the output value of glass wool will increase with the popularization of environmental protection concept in the next few years
