Hygrothermal Properties of Cladding Materials at Different Temperatures and Relative Humidities
The reliability of the analysis of heat, air, and moisture transfer phenomena in building envelopes depends on hygrothermal properties inputs of construction materials in the exterior layers of the building envelope, including cladding materials. Due to the dependency on temperature and relative humidity, determining hygrothermal properties for a building material is technically challenging and needs substantial time and resources. In this paper, thermal conductivity, adsorption isotherm, vapor permeability, and water absorption coefficient of stucco, clay brick, fiber cement board and western red cedar were measured at nine different climate conditions as a combination of the different temperature ranges of 3–60 °C and humidity range of 50–90%. Our results indicated that the water vapor permeability and water absorption rate in all cladding materials increased with increasing temperature, whereas the adsorption isotherm decreased with temperature. However, the thermal conductivity of all tested cladding samples increased linearly upon rising temperature.
