Abstract: In recent years, with the development of modern society, people’s aspiration for a better life has grown increasingly strong, and their dependence on energy has also continuously increased. The further expansion of industrial production and the excessive emission of CO₂ have made it impossible for natural ecosystems and other professional equipment to completely absorb these excessive emissions, resulting in a continuous rise in greenhouse gas concentrations. Greenhouse gases are highly transparent to visible light from solar radiation, and global warming remains a looming threat. Disasters caused by extreme high temperatures occur frequently, posing a global challenge that cannot be ignored. To effectively alleviate the temperature rise caused by solar radiation, reduce the load on air conditioning and other cooling equipment, and promote the application of thermal insulation materials, this paper classifies various thermal insulation materials through a story, and introduces the thermal insulation principles, advantages, and limitations of several materials respectively.
