Hygric and thermal properties of selected materials suitable for interior thermal insulation systems

The properties of three thermal insulation wood fiber boards suitable for the application on the interior side of historical building envelopes are studied in the paper. Water absorption coefficient, apparent moisture diffusivity, thermal conductivity, and specific heat capacity of all materials, as fundamental hygric and thermal parameters, are measured in a dependence on moisture content. The measured data will be used as input parameters in computer simulation studies which will provide moisture and temperature fields necessary for an appropriate design of interior thermal insulation systems.The properties of three thermal insulation wood fiber boards suitable for the application on the interior side of historical building envelopes are studied in the paper.
