This paper presents the thermal performance of the thermal insulation installed under the metal sheet roof. Three test houses were utilized in the experiments. First test house installed the glass wool thermal insulation (HGW), the second test house installed the asbestos thermal insulation (HAB) and the third test house was a reference house (Ref). The roof was fixed 5° (shed roof), and the volume of the room and the attic was 22.5 m3 and 5.4 m3, respectively. The thermal performance of the thermal insulation was expressed in terms of temperature, ceiling heat gain and percent heat gain reduction. The experiments show that the HGW had an insulation temperature lower than the HAB between 0.2°C to 3.2°C, while the maximum attic temperatures reduction of HGW and HAB were 5.7°C and 4.8°C, respectively. Moreover, the HGW and HAB were reduced the ceiling heat transfer than a reference house, while the percentage ceiling heat gain reduction of HGW and HAB achieved to 50.75% and 37.60%, respectively.
