Abstract
Through this study, the analysis of 6 types of plaster suitable for the rehabilitation of historical monuments is proposed. The proposed types of plaster have superior thermal insulating properties compared to commonly used plaster. The study is purely theoretical and aims to compare the efficiency of each type of plaster when applied as a rehabilitation solution to a case study building. The case study building is an historical building located in Timisoara for which classical facade insulation system cannot be applied due to its historical status. Their analysis and comparison will be carried out from an economic perspective, thermal transfer and water vapour behaviour and impact on the energy consumption of the building. The purpose is to identify the solution that is the most cost-effective.
