Abstract

Thermography is excellent for a fast characterisation of building materials, both at laboratory or in situ. A great advantage is the possibility to analyse many samples at the same conditions and time. A technique has been applied for new materials, oriented to radiating floor systems, evaluating different approaches. Samples are submitted to a stepwise, uniform heating. Surface excess temperature is recorded by thermography evaluating thermal inertia. At first, thermal diffusivity has been measured using a modified version of the Flash Method, then applied on a single face, for in situ application. Heat capacity and thermal conductivity have been inferred for each samples by definitions and the independent measure of the volumic mass.
