With the development of building energy-saving work, buildings with different structures and different insulation materials have appeared. The insulation technology of these different structures and different insulation materials has a great influence on the energy consumption of buildings. Thermal conductivity, heat storage coefficient, heat transfer coefficient, etc. are several performance indicators commonly used in thermal insulation building materials and architectural thermal design. Some of them have a great influence on the thermal insulation performance of buildings, and some have thermal insulation performance on buildings. The impact is great, and some have a great impact on the overall thermal stability of the building. Therefore, we should pay attention to the influence of the above coefficients on the insulation performance of buildings when choosing insulation materials and in the thermal design of buildings.
