Abstract
IR thermography, as known, allows the analysis of structural building elements on the basis of the identification of areas at different temperatures and possible heat transfer processes in close relationship with the response of the materials used to thermal stresses to which they are interested. The thermal images, especially if acquired through instrumentation characterized by high resolution and sensitivity, allow to put in evidence, in addition to the presence of anomalies associated with processes of alteration and degradation of the materials used, any architectural transformations 704 Atti 16a Conferenza Nazionale ASITA - Fiera di Vicenza 6-9 novembre 2012 occurred in the history of the article and, in particular, original characters constructive hidden by later interventions. Based on these assumptions, the thermographic method has been applied to the study of some of the historical and religious buildings in the country of Siliqua (south-western Sardinia): the Church of San Giorgio, the Church of Sant’Anna and the Church of Santa Margherita. The research, in particular, has made it possible to highlight the structure and texture of the main elevations of walls, now covered by plaster, and, on the basis of historical documents and photographs of the past, adjust the thermal response acquired with the specific materials used. For the study of historic buildings has been carried out non-destructive telemetry investigations through the use of Thermal Imaging Camera IR Thermo Tracer TH9260 (NEC Avio Infrared
