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.

　　Under the premise of ensuring indoor comfort, glass wool building energy saving can reduce the use of electricity, improve the utilization rate of energy, and reduce the total level of building energy consumption as far as possible. Glass wool insulation board has excellent thermal insulation performance, thus realizing people's economic expenditure.

　　Glass wool is developing towards the integration of energy saving, thin layer, heat insulation, waterproof and external protection. While developing new thermal insulation materials and related technologies, it is also necessary to understand what problems need to be paid attention to during installation, use thermal insulation materials more specifically, and design and install according to standards and specifications, The joints of glass wool and felt must be closely connected. If there are multi-layer insulation, all joints need to be interwoven to achieve heat resistance.
