Abstract

Thermal properties of materials are a crucial area of interest in the building industry. This study investigated the thermal properties of Polyvinyl Chloride (PVC), Plaster of Paris (POP), asbestos, and cardboard, commonly used as ceiling materials. The steady-state method was employed to determine the thermal properties; thermal conductivity, thermal resistivity, thermal diffusivity, thermal absorptivity, and density). The obtained results of thermal conductivity of PVC, POP, and Asbestos cardboard are  0.1083 w/mk, 0.1314 w/mk,  0.1068 w/mk  and 0.0851 w/mk, respectively, and are within range of values 0.0851-0.1314 w/mk  The thermal resistivity of the cardboard, POP, Asbestos and PVC are 11.7509 (w/mk)-1, 7.6103 (w/mk)-1, 9.3633 (w/mk)-1 and 9.2336 (w/mk)-1 respectively. The results of thermal diffusivity of PVC, Asbestos,  POP,  and cardboard are 6.34 x 10-7 m2/s, 6.0 x 10-8 m2/s, 1.20 x 10-7 m2/s, and 8.0 x 10-8 m2/s respectively. The results of thermal absorptivity of cardboard, PVC, POP, and Asbestos are  21.31 x10-2 m-1, 7.57 x10-2 m-1, 17.40 x10-2 m-1, and 15.07 x10-2 m-1 respectively. The density results of POP, PVC, Asbestos, and cardboard are 79.84 kg/m3, 203.59 kg/m3, 824.13 kg/m3, and 645.81 kg/m3 respectively. The results revealed some materials' thermal properties to understand the materials' behavior as they interact with heat fluctuation. In comparison, the results revealed that PVC and asbestos are better materials for building insulation since they have good thermal efficiency.
