Abstract
Interior insulation plays a key role in reducing the energy consumption of historic buildings. However, it might cause moisture accumulation and must be thoroughly analyzed. The use of recycled materials allows for further reduction of environmental impact. This paper presents the study of a new insulating plaster containing aerogel and recycled glass used as capillary active interior insulation system. Firstly, the hygrothermal properties of the material are measured in laboratory to obtain a complete characterization. Laboratory tests results are postprocessed to obtain the data required as input by the simulation software. Finally, hygrothermal simulations are carried out to investigate the material’s behavior in realistic application scenarios and to study how different input parameters affect the results.
