ABSTRACT This work investigates the thermal properties of polyvinyl chloride and asbestos ceiling sheet. We have studied the thermal properties of these materials in terms of the thermal conductivity (TC), thermal resistivity (TR), thermaldiffusivity, thermalabsorptivity, and specific heat capacity (SHC). With the view to establishing their suitability as ceiling materials in building designs for tropical regions. The result showed that thermal conductivity, thermal resistivity, thermal absorptivity, thermal diffusivity and specific heat capacity values of PVC and asbestos ceiling sheets falls within the range of good insulating materials like pine fibre-board and oak wood. With these properties and further improvement, they possess properties that can be harnessed for possible usage as ceiling materials.
