Thermal conductivity of Pterigota macrocarpa, Triplochiton schleroxylon and Nesogodonia papaverifera, all in the Steculiacea family was investigated. Samples of 50 mm by 50 mm were collected from the sawmill and turned into cylindrical form using the wood turning lathe machine with each sample having a radius of 20 mm and a thickness of 5 mm. The samples were placed between discs A and B of the modified Lee disc machine one after the other while the electrical plate was placed between disc B and C of the apparatus respectively and the thermal conductivity values for each sample taken while the temperature was monitored. The results showed that Nesogodonia papaverifera exhibited the lowest thermal conductivity with a mean of 0.22 Wm-1k-1followed by Pterigota macrocarpa and Triplochiton schleroxylon having a mean conductivity of 0.25 Wm-1k-1 and 0.27 Wm-1k-1 respectively. Also at hot rising and falling temperatures, Pterigota macrocarpa and Nesogodonia papaverifera exhibited highest and lowest thermal agitations at 0.32Wm-1k-1.The selected wood samples in the Steculiacea family possessed good thermal conductivity when compared with other wood species that their conductivity has been studied.
