Product Description:

Breathable Membrane

Description of 3 layer breathable membrane:
          Breathable membrane is thermal laminated by the high polymer material in the middle layer . Paving on the top of  the insulation system, it can strengthen the water tightness of the building, as well  as to eliminate humidity inside the containment by the unique breath ability,   thus  to  retain the duration of building effectively , playing a part  in thermal insulation,  energy conservation and living environmental improvement.

Building up principle of 3 layer breathable roof 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.

Operating principle:
          There are two kinds of operation principle for  breath:  microspore and hydrophilic group. Breawarf breathable roof membrane adopt  the principle of microspore. The minimum diameter of  water drop is  about 20 micron while the diameter of water  vapour molecule is about 0.0004 micron, because of the enormous difference, water vapour can get across according to the dif fusibility,  while water  molecule can't pass because of the surface tension.   As a result,  the breathable membrane can prevent osmotic water , so that to have the water proof  function.

Characteristics of 3 layer breathable membrane:
       A Excellent Performance at water resistance
       B Particular function of vapour permeability, so called breathable membrane


       C Good performance at UV resistance

       D Tear resistance, wear resistance, good extensibility.
       E Light and thin, antiskid, with good low temperature flexibility,  suitable for construction in different condition.
       F The 100% recyclable polymer materials, fit the ecologist requirements.

Function of 3 layer breathable membrane:
    Air-tightness of Breawarf breathable membrane
     Breawarf breathable membrane paves outside of the insulation system, wrap up the whole building, can strengthen air-tightness effectively and reduce air leak as well as convectional heat loss.

    Water tightness of Breathable roof membrane
      Thanks to the prominent water proof performance, Breathable membrane can wrap building tightly , protect the building from corrosion of water vapour and rain. Guarantee good insulat ion performance and well durability of building, enable the building to be more energy conservation and environmental protection.

    Permeability of Breawarf l3 ayer breathable membrane
      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.When condensation appears because of the temperature difference, the water drop will forming at the top of roof or surface of wall, incursion of such water drop into the insulation system will result in the lower thermal efficacy and shorter duration of building. After pave Breawarf breathable membrane, water vapour will exhaust easily . The water drop condensate inside the roofing tiles will drop to the Breawarf breathable membrane, flow away from the drain tank.

Reduce construction cost
  Breathable membrane can protect the insulation system,  saving the fine concrete or the film waterproofing materials which regularly paved on top of  insulation system so that  to reduce theconstruction cost.

Application of breathable membrane
         Mainly used as underlay for pitched roof and enclosure protection for insulating layer of walls.
