Analyses the effect of the flooring material and insulation layer on the heat transfer and temperature distribution by numerical simulation using the SIMPLER program and obtains the temperature distribution inside the floor. The results show that the flooring material has a notable effect on the thermal performance of the system and the insulation layer has an important role on reducing the heat loss.
