Thermal conductivities, specific heat capacities and bulk densities were determined for
some fibre samples from oil and raffia palms. Thermal diffusivities and absorptivities were
evaluated for each sample. Results show that the thermal conductivity values for the different
samples are within he range of the thermal conductivities of construction and heat insulating
material which is between 0023–29 Wm" K". Raffa palm frond fibre has the greatest thermal
diffusivity of 34 x 10" m's" while oil palm frond fibre has the least diffusivity of 19 x 10" m's". A …
