Faced insulation has a vapor barrier or a vapor retarder (the facing) that helps prevent moisture from moving from one space to another. The facing also helps protect the surface, hold the insulation together and fasten the material to building components.
What is the difference between faced and single faced insulation?
The main difference between faced and unfaced insulation is that faced insulation typically has a paper vapor barrier or retarder attached to one side of the insulation. The purpose of the paper vapor barrier is to block moisture from permeating the walls and ceilings of the home.
What are the 3 types of insulation?
