Waterproof breathablemembrane composed of PP non-woven fabric + breathable membrane+ PP non-woven fabric.The characteristic is waterproofing, breathable, good tensile, anti-skidding and environment-friendly .
waterproof breathable membrane benefits:
1.Protect the thermal isolation of the roof/wall against unfavorable impact of environmental factor that might penetrate the external covering.(rain, snow, dust)
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)
6.Stabilized, conforming to EU standards, resistant to UV radiation and excess temperatures.
7.Does not propagate fire.
8.Safe for environment and recyclable.
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.
