In winter, the amount of water vapor in the air is greater indoors than outdoors. Because of this pressure difference, the warmer water vapor tries to move from inside to outside. This is called diffusion of water vapor, or in colloquial terms, "the plaster breathes". Depending on the plaster mix used, the diffusing water vapor encounters a certain resistance (µ). The higher the water vapor diffusion resistance factor, the slower the water vapor diffuses through the material. Thermal conductivity is the ability of the material to conduct heat, i.e. the ability of the material to insulate. This property is described by the coefficient of thermal conductivity λ (expressed in W/mK). The lower the λ-value, the better the insulation capacity of the material. It must be mentioned that MP-75 Diamond plaster has an excellent thermal insulation capacity (0.47 W/mK). Thus, the lower the coefficient λ, the less heat loss.
