 high quality econimocal ASTM roofing synthetic underlayment breathable membrane

 

 

     How the "water-drop" come out? In different temperature, the air will contain different amount of moisture in itself, the warmer the more moisture. In winter, the air close to inside of wall or roof will be warmer, and when it pass through insulation layer and touches the cold roof tiles or shingle, it will fast condensation and become "water-drop". These water drops will fall back to insulation material, because of this, the insulation material will become wet. As it is inside of roof or wall, it will not easy to dry. And then, the insulation layer material will be damp and mould, been damaged quickly.

        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.
