With unique fiber structure, the waterproof breathable membrane 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 expel water vapour out of the construction, thus avoiding mould and condensation. In this way, the functions of construction can be well protected, which guarantee the energy saving and durability and good living environment. Furthermore, the waterproofing membrane has low cost and small weight, ect and is now waterproof rolls which are easy to apply.

 

 

 

About waterproof breathable membrane

What is waterproof 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.

Application:

waterproof 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 waterproof 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 waterproof 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.
