waterproof breathable housewrap felt / water resistant / vapour permeable / breathable housewrap felt / weather barrier

Breathable Housewrap is a water-resistant material which will allow water vapour to pass through when there is a difference in humidity on opposite sides of it. 

Breathable Housewrap are used on the outside of frame walls under the exterior finish material. They have three functions to perform:

to shed moisture and restrict any rain water which penetrates past the exterior finish from reaching the wood wall,to perform as a breather material allowing any moisture within the wall cavity to escape by diffusion through the membrane to the exterior, andto act as a wind barrier to restrict movement of air through the wall.

To qualify for the above functions the breather housewrap must have good "water resistance", good "water vapour permeability", and good "air barrier properties".
