How does climate impact permeability? In general, water vapor moves from the warm side of a wall to the cold side of a wall. This means that it tends to go from the inside out in northern climates and from the outside in .Permeability of Common Building Material to Water Vapor WHAT IS A PERM RATING? If a material has a perm rating of 1.0, 1 grain of water vapor will pass through 1 square foot of the material, provided that the vapor pressure difference between the cold side and the warm side of the material is equal to 1 inch of mercury (1 inch Hg).Materials which are able to take in or let out moisture either need to be porous or selectively permeable. Membranes are products which are permeable to low molecular weight products or ions. In this work we will discuss mainly microporous or hydrophilic films, coatings and impregnations, i.e. materials permeable to water vapor.

for water vapor it is given in units of mass of water vapor. Sometimes, the amount of permeant is given in moles. Sometimes the term “diffusion coefficient” is used incorrectly instead of permeability, which are different properties, leading to additional confusion. Another complication involves the water vapor transmission rate (WVTR). Cup experiments are the most widely used method to measure the water vapor permeability of porous building materials. For this test, cup assembly is designed to create a vapor pressure gradient across a sample and, thus, to allow vapor diffusion through it. Water vapor permeability is assessed by weighing cup assembly over time.
