3 layer waterproofing breathable roofing membrane

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

Breather membrane for timber frame wall construction





About Breathable membrane Application:

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:


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 ma
ke 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.




Our lab is certified by National Certification Department.
