hing quality pitched roof underlayment films

1, Description:
Pitched roof underlayment films have excellent performance at water resistance, vapor permeability and UV resistant, which is mainly used in construction as roof underlay and house wrap.
Roof underlayment filmsare 3 layers thermal lamination:
PP non-woven fabric on top and bottom layer for protection and reinforcement;
Micro-porousPEfilm in the middle layer as breathable membrane.
2, 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
6)100% recyclable
7)Simple installation in new building, re-roofing and refurbishment situations

3, 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 insulationmaterials 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.
