breathable waterproof membrane synthetic roofunderlayment roof felt

     Why use it?

KangDa Vapour Permeable Underlay (C100)   

        While being highly resistant to wind and water penetration from the outside Kangda breathable membrane is highly “diffusion open” on the inside giving it the ability to freely transport moisture from within the inner wall or roof cavity to the outside. This effectively prevents the mould and subsequent structural damage that can result when moisture becomes trapped during construction, and over time, from driving rain and internally driven dampness caused by condensation when humidity levels are high. Adding to the risk of structural decay is the wall and roof insulation which also becomes damp as a result of trapped moisture.

KangDa vapour barrier roof membrane

         Polypropylene breathable roofing membrane used for pitched roof underlay. High permeable membrane allows moisture to get of out roof easily, while pitched roof allows the few drop water caused by condensation on the upper surface of breathable membrane to flow down of roof edge quickly.
