KangDa Breathable Membrane (MF160)   

        "Breathable membranes for walls tend to be of a generally lower specification than those used within roofs due to the nature of the application. Normally a roof breather would also be suitable as a high specification wall breather, but a wall breather would almost certainly not be suitable for use in a roof.

         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.
