Abstract

Due to the ozone layer depletion, many houses suffer from high thermal solar radiation effects during the dry season in Nigeria's southern and northern parts. This issue makes the use of an insulated roofing system more significant to have a comfortable environment. This research aims to proffer a solution by evaluating the performance of Polyurethane's (P.U.) foam as a thermal insulation material embedded in the aluminum roofing system for adequate human comfort. The thermal analysis was carried out using a data logger to obtain the temperature data with time variation for the two house models' indoor and outdoor environments. The study was carried out for two hours in the morning, afternoon, and evening for both the Polyurethane Aluminum roofing and the Non-Polyurethane roofing. The authors employed a contour plot for one-factor analysis to study the time variation effects on the roofing house models. The results show that the P.U. embedded aluminum roofing sheet reduces the temperature by 5% in the morning, 16% in the afternoon, and 10% in the evening compared with the Non-Polyurethane roofing sheet. Furthermore, the P.U. foam application on the aluminum roofing shows a uniform heat distribution and provides a sustainable, eco-friendly environment. This study recommends that the manufacturing industry producing roofing sheets should be use PU-form as an insulation material for cleaner and eco-friendly thermal comfort.
