The purpose of using a household wrap is to prevent moisture from entering the wall cavity from outside. While home wrap is water resistant, it's generally not waterproof or waterproof, for good reason. Just as rain and humid air can enter a wall cavity from outside the house, moisture-laden air can also enter a wall from inside the house.

Most WRBs have a permeability index between 5 and 60; most building codes require a minimum of 5.
