Abstract: This study aims to provide insights regarding the benefits of multilayer insulations in building applications placed in combination with two air gaps. For this purpose, a numerical approach was developed to determine the best multilayer insulation position. A combined radiation/conduction heat transfer numerical model was employed to predict the temperature distribution and heat transfer in multilayer insulation complexes comprised of insulating materials separated by multiple reflective foils. The radiation scheme was based on the two flux approximation, in order to model both optically thick and optically thin fibrous materials. The heat transfer equation was solved explicitly for a composite wall. Total nine different configurations were selected as initial state, where the theoretical thermal resistances were calculated and compared.
