Research on Environment Dependence of Thermal Conductivity of Expanded Polystyrene Foam Board

Abstract:

Thermal conductivity of expanded polystyrene foam board (EPS) is affected by the environment when used as insulation material in the building. In order to simulate the impact on EPS in the building and test the thermal conductivity of EPS in different conditions, we conducted a simulation study, including temperature and humidity simulation tests, freeze-thaw tests and mechanical tests. This study of EPS in different environmental conditions established a good foundation for further research on environment dependence of thermal conductivity in national codes.
