Among the many insulation options available for the homeowner there is one that stands above the rest.
Faced or unfaced insulation in walls.
That s how the barrier is made effective.
Kraft faced insulation should be installed in exterior walls exterior basement walls and attic ceilings by pressing the product into the wall cavity with the paper side facing outward towards the installer.
More often than not faced insulation is made out fiberglass.
It s also important that there be no air pockets in the insulation as this is where the cold spots spring up in rooms.
Paper faced insulation means that one side of the insulation material comes lined with paper.
Faced or the type with paper is typically used in first time applications such as in walls ceilings floors and in crawl spaces.
This is usually kraft paper but sometimes other types of paper can be used.
Unfaced means the insulation lacks a vapor retarder paper or plastic facing.
Unfaced insulation the type without paper is what you would use if you are adding insulation to your attic or to place between floors when living space is above and below.
Any time you use a faced insulation the paper needs to be facing toward the living space.
Unfaced batts on the other hand fit in wall cavities by friction.
Faced insulation is a type of fiberglass batt insulation wherein the facing is either stapled to the sides or to the face of the studs.
Without stapling moisture still has a path into the room.
Unlike unfaced insulation faced insulation has a vapor retarder that keeps moisture out.
Insulation comes either faced or unfaced which is when the paper is attached to one side.
To this end you insulate your home.
The primary function of the vapor retarder is to keep moisture from spreading within the walls and throughout the house.
