Specifications

Breathable membrane 130g/m2:
has good water resistance and vapor breathability, let building breathe freely.

Breathable Membrane 130g/m2 roofing waterproofing membrane :

 

Nelumbo  breathable membrane, which has good water resistance and vapor breathability, e.g., prevents moisture from entering the buildings, while permits water vapor exit the building. And the breathable membrane can thus improve building durability by protecting wall sheathing and framing from moisture.

 

One key point :   Nelumbo Waterproof breathable membrane can keep the warming  for the building ,so it is very good to energy conservation . It is very popular in the domestic and abroad.

 

How does Nelumbo  Breathable Membrane 130g/m2 roofing waterproofing membrane works?

 

Nelumbo breathable membrane is made by two layers of non-woven fabrics and one layer of microporous polymeric membrane in the middle. 

 

1. It has superior air resistance that helps to protect insulation from drafts, reducing energy costs.

 

2. It provides water resistance that  helps to prevent water from entering walls, avoiding costly damage.

 

3. It allows moisture vapor to escape while protecting against air and bulk water instrusion.

 

4. It has excellent tear strength and allows 120days of UV exposure.
