What is the difference between backing&loft insulation?
14/02/2013 · First, the kraft paper is a vapor retarder meant to reduce the potential for moisture problems caused by diffusion. Sounds like a good idea, but the vast majority of moisture problems are caused by air leakage, not diffusion, even in places like Maine. Do the air sealing; stop worrying so much about vapor retarders.
Why does insulation have paper?
Vapor barriers—sheets of plastic or kraft paper—keep water vapor out of the wall cavity, so the insulation stays dry. Not every type of insulation needs a vapor barrier. But if it does, the barrier should face inside in northern, heating climates, and outside in humid southern climates.
Should insulation have a paper backing?
Regardless of whether fiberglass insulation is installed in a wall, attic, or crawlspace; the paper facing should always face toward the inside of the home. That's because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it.

What is the purpose of a facing on a wall?
The Purpose of Insulation Facing. The facing on kraft-faced insulation is made of kraft paper with an asphalt coating that makes the paper impermeable to water vapor.

Unfaced Insulations are made from fiberglass roll or batt insulation products and have no kraft paper attached to them. Unfaced Insulations, therefore, lack vapor barrier/retarder.
What R-Value Faced or Unfaced Insulation Do You Need?
R-value is used to determine the air resistance offered by an insulation product. R-value is often a correlation to the thickness of the insulation. As insulation compresses (either by age or contact), it loses R-Value.
