Water vapour permeability ISO 7783-1

When painting an exterior wall, it is very important that the paint protects the wall against water and rain, but it is also important that the wall continues to 'breathe', i.e. remain permeable to water vapour. The water vapour permeability of a paint layer is tested in the lab according to the ISO 7783-1 standard.
