A hygroscopic material has the ability to adsorb and store moisture from the surrounding air. When the RH changes, a difference in the vapour partial pressure results in the material absorbing or desorbing moisture in order to reach equilibrium. Most materials have a hygroscopic potential which is too low to have any impact on indoor […]
Relative Humidity

In addition to the energy performance and durability of the building envelope, one of the most significant factors within the indoor environment is the relative humidity of the air (RH), which influences the comfort of occupants and the indoor air quality (IAQ). A steady indoor environment, with a small range of temperature and RH variation […]
