Production Technology of breathable membrane:
   3 layer breathable roof membrane,  thermal laminated by high polymer material + polyolef in microporous membrane + high polymer material, we create this technology in China which is advanced  all over  the  world. Polyolefin microporous membrane has excellent breathability, as well as good duration. Polyolefin microporous membrane has not only acid and alkali resistance, but also good extensibility which enable the fasresilience after tearing by nail so that  to improve the sealing performance.

Roof Application
Kedebon breathable membrane is widely used for many roofs,including wooden pitched roof,metal roof and so on.Breathable membrane is placed under the exterior roof and its primary function is to work as a shield that protects the thermal insulation material and the building structure from the destruction of the weather.
For metal roof(widely uesed in China's market):

Wall Application
  Waterproof and breathable membrane is widely used as house wrap in buildings.It looks like the comfortable clothes of the house,keep the rain and condensate water away from the wall insulation,the most important is moisture may pass throgh the membrane,that is why we call it breathable membrane.
