μ Vapour diffusion resistance factor
The water vapour diffusion resistance (μ value) is a parameter to determine the exchange of moisture of a construction material. The lower the μ value, the easier it is for vapour to penetrate a substance.

Definition: Ratio of the vapour diffusion coefficients of the air and that of the relevant substance.
