Variations in wood thermal properties of triploid clones of Populus tomentosa were reported. Significant differences among triploid clones of P. tomentosa were observed. Clonal repeatabilities of specific heat coefficient, thermal conductivity and warm-transfer coefficient were 0.59, 0.77 and 0.62 respectively, indicating that wood thermal properties were under moderate or strong genetic controls. Positive correlation existed between wood thermal property and wood density. There was a significant correlation between thermal conductivity coefficient and wood density.
