In addition to thermal conductivity, water absorption, combustion performance, strength, and other indices of the material should also be considered. Performance characteristics of different insulation materials can be found in the corresponding classification criteria.

　　Inorganic insulation materials are generally materials with thermal conductivity less than or equal to 0.2.

　　Using good insulation technology and materials in buildings and industry often yields twice the result with half the effort. Statistics show that every ton of mineral-wool insulation used in buildings can save one ton of oil per year.

　　Adoption in energy-saving communities shows that the coal saving per unit area is 11.91 kg of standard coal per square meter per year. For insulation of industrial equipment and pipelines, good insulation measures and materials can greatly reduce production energy consumption and cost, improve the environment, and yield better economic returns. For example, in industrial equipment and pipeline projects, good insulation can reduce heat loss by about 95%, and the investment in insulation materials can generally be recovered in about one year through energy savings.
