Hi Kim, 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.
Does wiring go in front of or behind insulation?

Should I use Faced or unfaced?
Faced insulation is easier to install. This is because the insulation is held together by the paper vapor barrier, allowing the faced insulation to be rolled, moved, and stapled without falling apart. Unfaced insulation does not have the same cohesive strength, so it’s more susceptible to tearing during installation.
Is it OK to put plastic over faced insulation?
More than likely, installing an additional layer of poly over kraft facing won’t cause any problems — it’s no more risky than if the wall had only unfaced batts and poly — and the risk of using poly on the interior is relatively low in a cold climate like New York’s.
Is kraft paper a vapor barrier?
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.

What is the difference between R13 and R30 insulation?
There is a direct relationship between the amount of insulation and the amount of heat transfer. The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.
What's better R13 or R15?
Is R15 Better than R13? Answer: There isn’t much difference between R13 and R15. However, higher R values offer higher performance. Therefore, in the case of efficiency, R15 is better than R13.
What is a batt of insulation vs roll?
