A number of common tropical timbers have been subjected to thermal analytical investigation as part of a wider research programme under air atmospheric conditions. Thermal parameters obtained were correlated with oven‐dry densities of the timbers. Two well‐defined pyrolysis stages have been observed which occur over the temperature ranges 201–426°C and 397–557°C. The kinetics of the thermal degradation of the timbers were obtained using Broido's analytical procedure. These results were interpreted on the basis of the known mechanism of pyrolysis and the calculated kinetic parameters were discussed within the context of other published values for cellulose.
