high quality and low price Breathable Membrane for roofing and house wrap

Polypropylene breathable roofing membrane used for pitched roof underlay. High permeable membrane allows moisture to get of out roof easily, while pitched roof allows the few drop water caused by condensation on the upper surface of breathable membrane to flow down of roof edge quickly. Because the roof membrane has not only the function of breathable, but also the function good waterproof. As the polypropylene spunbond fabric is water repellent itself, the water drop will not be absorbent by the membrane, but will keep it as round water drop and fall off the roof. So the spunbond roofing membrane is the best choice for this roofing membrane, and it is very cheap compare to other material. 

1. KangDa" breathable membrane has excellent performance at water resistance, high vapour permeability, Good performance at UV resistance and 100% recyclable polymer materials, fit the ecologist requirements.
2. Water tightness of "KangDa" breathable membrane: Thanks to the prominent waterproof performance, "KangDa" breathable membrane can wrap building tightly, protect the building from corrosion of water vapour and rain, guarantee good insulation performance and well durability of building enable the building to be more energy conservation and environmental protection.
3. Permeability of "KangDa" breathable membrane: "KangDa" breathable membrane paves outside of the insulation system, enable the water vapour inside the insulation system to exhaust, solve the condensation problem, protect the insulation system.
4. Reduce construction cost: "KangDa" breathable membrane can protect the insulation system, saving the fine concrete or the film waterproofing materials which regularly paved on top of insulation system so that to reduce the construction cost.

About Breathable membrane

What is breathable membrane? It allows the moisture to get out of the pitched roof, avoiding mold and condensation, thus the functions of construction can be well protected. 

KangDa Breathable roofing membrane is a three layers membrane. (Thermal laminated by non woven PP + waterproof and vapor permeable membrane + non woven PP). It is a kind of roof deck protection, can protect the construction structure from being eroded by wind and rain and strengthen the gas tightness and water tightness as well as boast good breathability which expels water vapor out of the construction, thus avoiding mould and condensation.  

The specification of breathable membrane:

Weight (per square meter): 80gsm to 200gsm

Roll Width: 1m-1.5m-3m

Roll Length: 50m or Jumbo roll 

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.

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! Maxssive production is ver 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 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.

Testing:

Our lab is certified by National Certification Department.

Exhibition:

Batimat show in Paris!

International Builder's Show in Las Vegas!

Certifications:

Our company has ISO9001 and CE certification for years. Interteck or CCMC test has been passed by us.
