1. Breathable roofing felt: This material is added to the external covering of the roof/wall to protect the thermal isolation against unfavorable environmental factors such as rain, snow, and dust. It is recommended to use the best breathable roof membrane for optimal performance.
2. Breathable felt: This material ensures the windproofing of the roof/wall, preventing the loss of heat from the isolation layers caused by air circulation. Consider using an Amazon breathable membrane for effective windproofing.
3. Black breather membrane: This membrane has micro-perforations that allow vapor to escape to the outside, ensuring the dryness of the isolation layer. This is important as dry isolation functions properly. Look for a black breather membrane for enhanced moisture management.
4. Complete waterproofing: The membrane also acts as a barrier, preventing the penetration of water from condensation or leaking in the covering. Consider using a breathable membrane with excellent waterproofing properties.
5. Resistant to mechanical damage: The breathable roofing felt, breathable felt, and black breather membrane are all resistant to stretching and tearing, providing durability and protection. Look for a breathable membrane that offers high resistance to mechanical damage.
6. Stabilized and conforming to EU standards: These materials are designed to be resistant to UV radiation and excess temperatures, ensuring their longevity and performance. Choose a breathable membrane that is stabilized and conforms to EU standards for reliable performance.
7. Does not propagate fire: The materials used for the breathable roofing felt, breathable felt, and black breather membrane are non-combustible and do not contribute to the spread of fire. Look for a breathable membrane that is fire-resistant for added safety.
8. Safe for the environment and recyclable: These materials are environmentally friendly and can be recycled, reducing their impact on the environment. Consider using a breathable membrane that is made from eco-friendly materials and is recyclable.

Producing Process:

From making spunbond fabric,to membrane lamination,to logo printing and to rolls cutting,using our own machines! Lower production cost and control quality .Flow line production enable us to produce out one container quantity in two days only! Maximum production capacity is 60000m2 per day.

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 polyethylene, 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.

Question: What is the loading quantity?

Question: If pallet packing is available?
Yes, above loading quantity is for free loading, pallet loading quantity will be less.
Question: If customer logo is available?

Yes, but the price will be different. 

Question: What is the Lead time?
15-20 days for without logo
25-30 days for with logo
Question: How about the sample?
Free sample is available for small pieces, roll sample should be freight collected.
