Low Preice Waterproof Membrane

1.   Breathable Membrane is a water resistant membrane but with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls

      1    Breather membrane functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior. 

      2    Breather membrane may also serve as an air barrier if it is sealed carefully at seams.

      3    Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".

2.Kingway breathable membranes are 3 layers thermal lamination:

PP non-woven fabric  on top and bottom layer for protection and reinforcement;

Micro-porous PE film in the middle layer as breathable membrane.

3. Advantages:

1)Excellent performance at water resistance

2)Particular function of water vapor permeability,

3)Good performance at UV resistant for 3 months

4)They are much lighter than bitumen felts, suitable for construction in different condition

5)They have excellent tensile and tearing strength, with good low temperature flexibility,

6)100% recyclable

7)Simple installation in new building, re-roofing and refurbishment situations

4. Application

 1) Mainly used as roof underlay and house wrap protection for insulating walls. 

 2) Prevent rain and snow meanwhile allow water vapor to pass to the exterior. so the moisture from leakage          and condensation can escape to avoid mold and rot of fiberglass or cellulose insulation, to keep its R-value.

 3) Used as windproof layer (Air barrier), reducing air leakage through the building envelope, ensuring insulation      materials maintain their optimum thermal efficiency by minimizing air infiltration

 4) Used as a temporary waterproofing barrier during the construction process.

Mainly used as underlay for pitched roof and enclosure protection for insulation layers of walls.
