Thermal conductivity, specific heat capacity and density were measured for Musanga cecropioides (Corkwood) heartwood sample obtained from a bush at Afaha Oku in Uyo, Akwa Ibom State, Nigeria. Thermal resistivity, diffusivity and absorptivity were also determined for the sample to establish its suitability as construction material for cooler, food flask and refrigerator, from an energy conservation point of view. Results showed that the thermal properties of Musanga cecropioides heartwood compared favourably with those of similar construction materials. In fact, Musanga cecropioides heartwood is a better thermal insulator than most known resources. The material could be used as an efficient heat insulator in various interior spaces, if properly harnessed.
