Determination of the thermal conductivity of some selected roof ceiling materials in Taraba State, Nigeria

In our homes, indoor thermal discomfort has been very challenging and it depends on one or more of the materials used either as ceiling board rock used as walling materials; woods used in making doors and wood sample used in making roofing supports the roofing sheet itself or combination of all of them. Observation in the present competitive world reveals that people that are economically favored usually go for the costliest ceiling materials without preference to the thermal conductivity of the most sought after ceiling materials. It is based on this premise that this work designed to determine the thermal conductivity of the most frequently used ceiling materials and to predict the most suitable ceiling materials to be used especially in tropical regions. This research work encompasses the variation of thermal conductivity (with different types) of roofing ceiling. The Lee disc method will be used to determine the thermal conductivity of Plaster of Paris (POP), Polyvinylchloride (PVC) and Aesthetic timber wood. This project shall provide guide for the choice of the types of roof ceiling materials to be used in tropical regions and the rate at which they conduct heat.
