Specifications

waterproof breathable membrane has water resistance and vapor breathability prevents moisture from entering roof.

waterproof breathable membrane :

 Microporous membrane is a very thin layer of polymer membrane, there are lots of microcellular on the surface, which diamteres less than 2μm, water drop diameter is about 100μm, water vapor diameter is about 0.0004μm. So it's available for waterproof and breathable.

 

 

waterproof 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.

 

The key point it can keep warm for the building ,environmental and energy saving .

 

It is irreplaceable to the building keep warm , and very popular in the domestic and abroad .
