Water vapour Permeable Breather membrane used for pitched roofing underlayment or steel construction Feature: Good tearing strength, waterproof, good breathability, soft handle, heat insulation Excellent performance of breather membrane allows vapour to pass through while keep water or rain outside, it can keep the construction structure dry and long term usage. Constructed from high tensile spun-bonded polypropylene layers Highest levels of water resistance Full moisture vapour permeability Breathable underlay for tiled and slated pitched roofs Eco-friendly to be completely recyclable UV resistant Others as buyers requirements
Material: A three layer highly breathable, fully waterproof membrane, constructed from high
tensile spunbonded polypropylene layers, combined with a microporous polypropylene film. The outer
layer forms the functional waterproof surface; the middle layer is the breathable waterproof
membrane and the inner layer protects the membrane from abrasion and damage, also
giving additional strength. Such structure enables the fabric to allow moisture vapour to pass through,
whilst remaining fully waterproof. We can provide various colors on upper surface, printed with
the customer’s logo and head lap lines.
Use: Breathable roofing underlay positioned immediately above the insulation layer in a warm
pitched roof, or in a cold pitched roof (ventilated or unventilated). Breathable roofing underlay
for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates

About Breathable membraneApplication:
Breathable membrane mainly for used as pitched roofing underlay for European customers, and mainly used for house wrap or wall wrap for America customers, as for our China mainland customer, the breathable membrane is used for steel construction. After years of deverlopment, we have reached out different ways to produce different breathbility membranes, which will sastisfy different customer's requirements.
Raw material: 100% top virgin grade polypropylene! The PP spunbond nonwoven is made of 100% polypropylene, and the breathable film inside is also made of polypropylene, added with our special breather pigment, which is made by ourselves!!
Printing and Slitting: As a OEM factory, we would like to make customer's logo on the breathable membrane. Our company now have 3 printing lines, two of which are silk-screen printing. The silk-screen printing makes the logo very clear, any kind of color is acceptable; the shortcoming is the low speed of production, higher cost. and only one color logo is available.
Packing and Delivery:
Packing: Normally is free PE wrap, with two inches paper core inside. Our new shrink film packing machine will be added by the end of this year. Free loading and pallet packing loading are both OK. Customer specialized label is available.
