In the framework of historical buildings, the wall thickness as well as the wall constituents are often not known a priori and active IR thermography can be exploited for detecting what kind of material lies beneath the external plaster layer. In the present work, the transient thermal response of walls made of different known materials underneath the plaster layer are simulated by validated numerical models. Meanwhile the surface temperature temporal trend of an unknown wall is recorded by an IR camera. The experimental data are finally compared with the simulations in order to identify what material lies under the unknown wall. An interesting qualitative accordance between the experimental results and the most common materials used in this zone has been observed.

Abstract
In the framework of historical buildings, the wall thickness as well as the wall constituents are often not known a priori and active IR thermography can be exploited for detecting what kind of material lies beneath the external plaster layer. In the present work, the transient thermal response of walls made of different known materials underneath the plaster layer are simulated by validated numerical models. Meanwhile the surface temperature temporal trend of an unknown wall is recorded by an IR camera. The experimental data are finally compared with the simulations in order to identify what material lies under the unknown wall. An interesting qualitative accordance between the experimental results and the most common materials used in this zone has been observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
