Mould growth risk evaluation of internal insulation solutions in a historic building under temperate climates
Retrofit interventions in historic building’s envelope usually involve internal thermal insulation. Several authors show how this intervention could affect internal hygrometric conditions and cause mould growth especially in cold climate. Mould growth risk could be enhanced by specific installation conditions, as the necessity of wet bonding surfaces for a better adhesion of particular insulation typologies, which may determine high water contents in the envelope materials for long time. This paper reports the results of the hygrothermal experimental assessment of two internal insulation systems (one based on a capillary active insulation and the other one on a synthetic insulation) installed on the wall of a historic building in a temperate climate. Indoor and outdoor environmental conditions, as well as temperature and relative humidity in each layer of the renovated wall, have been detected for almost one year. Obtained results demonstrate that high water content in the wall surfaces and interfaces may last for a long time after the insulation installation and cannot be disregarded, as it can be very influential on the historic materials decay and mould growth risk.
