KINGWAY vapor barrier breathable membranes are 3layers thermo-bonded: PP non-woven fabric of top and bottom layer for protection and reinforcement; Micro-porous PE film, between the two layers, is to form breathable membrane. They are polyolefin products that can easily be recycled and can even be categorized as a normal household waste.
1) vapor barrier Breathable membrane with excellent waterproofing properties.
2) High water vapor permeability.
3) Stable anti-UV & anti-aging performance.
4) 3-layers thermal laminated: PP+PE+PP.
5) Light weigth so easy handled.
6) Excellent tensile and tearing strength.
7) Good low temperature flexibility.
8) For both roof and wall application.
9) High quality with very competitively price.
Products characteristics and function
KINGWAY vapor barrier breathable membrane has excellent performance at water resistance, high vapour permeability, Good performance at UV resistance and 100% recyclable polymer materials, fit the ecologist requirements.
Water tightness of "KINGWAY" vapor barrier breathable membrane: Thanks to the prominent waterproof performance, "Complon" breathable membrane can wrap building tightly, protect the building from corrosion of water vapour and rain, guarantee good insulation performance and well durability of building enable the building to be more energy conservation and environmental protection.
Permeability of "KINGWAY" vapor barrier breathable membrane: "KINGWAY" 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.
Reduce construction cost: "KINGWAY"vapor barrier 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 the construction cost. Application Mainly used as underlay for pitched roof and enclosur protection for insulating layer of walls

KINGWAYTM vapor barrier breathable membranes are commonly use as waterproof underlay beneath the roof covering, which impervious to any wind driven rain or snow that gets blown through the roof covering, even when in direct contact with timber rafters and insulation.
Meanwhile as they are vapor permeable, allow the roof structure to breathe, so the moisture from leakage and condensation can escape, to avoid mold and rot of fiberglass or cellulose insulation, so won’t lose its R-value due to heat-conducting moisture.
