Moisture Dependent Thermal Properties of Hydrophilic Mineral Wool: Application of the Effective Media Theory

Popis výsledku v původním jazyce

Thermal properties of mineral wool based materials appear to be of high importance because the most widespread practice is using them as thermal insulation boards. Their thermal conductivity is easily found, i.e. data sheets from producers, often including specific heat capacity, but usually only characteristic values for dry state. Exposure to outside climate or any other environment containing moisture can negatively affect the thermal insulation properties of the mineral wool. This is why the presence of water inside the mineral wool is undesirable for the majority of applications; so, they are often provided with hydrophobic substances, whereas hydrophilic additives are seldom used. However, the later combination has good potential for some applications (i.e. desalination of masonries and green roofs). In those cases, mineral wool will work with a certain moisture content, which will change the thermal properties it had in the dry state. On this account, moisture dependent thermal
