Each time a constructing is air-conditioned, the vapor-pressure gradient is from the outside towards the interior, where by condensation within the again side with the intentional vapor retarder might come about. The specific situation is aggravated Should the setting up's cladding is composed of a fabric, such as brick or split-face block veneer, that absorbs rainwater, as the vapor-stress driving power is significantly enhanced in the event the Sunlight raises the temperature with the veneer to that of liquid water.
