Breather membrane and breathable roofing felt avoid roof condensation

     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.

KangDa Waterproofing Membranes   

        High performance breather membrane with a highly reflective surface used to enhance the thermal performance of the final wall construction.

KangDa vapour barrier roof membrane

         Permeability of "KangDa" breathable membrane: "KangDa" breathable membrane paves outside of the insulation system, enable the water vapour inside the insulation system to exhaust, solve the condensation problem, protect the insulation system.
