Summary/Abstract: Researcher have used the microscale combustion calorimetry (MCC) in order to test thermal properties of common materials used in construction [such as the cardboard found in the componence of the plasterboard (PBD), expanded polystyrene (EPS) used for seiling decorations, wallpaper made of polyvinyl chloride (PVC) and wood particleboard (PB)] having masses between 3 and 20 milligrams. All four commercial materials have a long history in construction field with over 100 years of being used for design or insulation and they have different fire behaviours performances. The analysis were conducted under controled conditions which suppose a gradual increase of the temperature in the pyrolyzer with a heating speed equal to 1,5 ⁰C/s up to 750 ⁰C in a nitrogen atmosphere at an 80 cm3/min flow and a constant temperature value in the combustion chamber equal to 900 ⁰C in a nitrogen (80 %) and oxygen (20 %) atmosphere at a 20 cm3/min flow.
