Water vapor permeance is a measure of how easily water vapor can pass through a material. It is expressed in perms, which are the number of grains of water vapor that can pass through a square foot of material in an hour at a pressure difference of one inch of mercury. The higher the perm rating, the more easily water vapor can pass through the material.

Water damage can lead to a number of health problems, including mold growth and respiratory infections. It can also damage building materials and furnishings, leading to costly repairs.
