This study determined the heat of combustion characteristics of selected building ceilings materials. The study was intending to appraise the flame affinity or retardance of building ceiling materials during combustion. Careful selection of ceiling composite was carried out in areas like Osun state, Ogun state, Lagos state, and Kaduna State. The heat of combustion was determined, having identified the heating value from the XRY-1C Oxygen Bomb Calorimeter. The heat flux and heat release rates were determined from the results of the combustion experiment. Based on the data obtained from the discrete experiments, the combustion integrity of the samples was appraised. Particleboard has the highest heat of combustion of 45.666J/kg, while asbestos failed to ignite. Other Polyvinyl chlorides (PVC) left ≤ 0.0007kg of char after combustion and became deliquescent after long minutes of exposure to air. The heat release rate is highest with particleboard, 118.9219 J/s, and lowest with sample 7, 2.230 J/s. The study thus establishes that PVC is safer in terms of combustion properties compared to plant-based building ceilings. Asbestos has the overall most reliable properties, but for asbestosis, its use isn't safe for use. It is necessary to develop building ceilings with flame retardant characteristics of asbestos as an alternative to it.
