Abstract: Thermal conductivity is an important index for evaluation of the thermal insulation performance of thermal insulation materials. The thermal conductivity of extruded polystyrene (XPS) boards with different surface structures was investigated. The results indicated that the thermal conductivity of XPS boards with a grooved surface was slightly influenced by their surface structure. There is a fair structural influence on the thermal conductivity of XPS boards with the one side removed from the skin. However, the thermal conductivity of the XPS board with the doublesides removed from the skin was reduced significantly.

Key words: extruded polystyrene boards, thermal conductivity, plastic foam, surface structure
