Breathable membranes allow insulated structures to easily release excess moisture vapour into the atmosphere and so keep the internal components of wall and roof structures dry, whilst performing the task of a secondary protection membrane and preventing penetration by external environmental impurities such as dirt and rain. These types of membrane are installed on the cold side, or the external side of the insulation beneath the main outer building lining, roof-tiles or cladding.
