The Influence of Moisture on Thermal Conductivity for Building Materials

Abstract

The purpose of the study is to determine the influence of moisture on thermal conductivity for a range of building materials. A series of building materials and insulation materials have a porous, fibrous or granular structure, in which blanks are filled with air. If these areas are filled with moisture or water, the thermal conductivity of the material increases, and the insulation capacity decreases. The thermal conductivity of the analyzed materials was measured in accordance with ISO 8301 protocols.
