Waterproof Membrane for Roof and Wall

                    Nantong Kingway Complex Material Co.,Ltd

This product in a high performance vapour permeable roofing underlay for use in warm or cold pitched roof constructions.

Embossed wine red upper surface, white lower surface, printed with logo for ease of identification.Triple-ply construction, with a waterproof and vapour permeable core laminated and protected between two layers of spun-bonded polypropylene.

1.       Protect the thermal isolation of the roof/wall against unfavorable impact of environmental factor that might penetrate the external covering.(rain, snow, dust) housewap

2.       Ensures the windproof of the roof/wall (prevents the loss of heat from the isolation layers caused by air circulation.)

3.       Micro-perforation permeates vapor to the outside, ensure the dryness of the isolation layer.(only dry isolation functions properly)

4.       Complete waterproofing, the membrane prevent the penetration of water from condensation or leaking in the covering.

5.       Resistant to mechanical damage (stretch and tearing) housewap

6.       Stabilized, conforming to EU standards, resistant to UV radiation and excess temperatures.

7.       Does not propagate fire.

8.       Safe for environment and recyclable.

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.
