What happens if insulation is installed backwards?

The problem is that the paper acts as a vapor barrier. So if it is installed upside down, the paper moisture barrier can actually keep moisture in-between the paper and the sub-flooring. This can lead to mold issues, as well as structural deterioration.

What is the difference between faced and unfaced insulation?

The Difference Between Faced And Unfaced Insulation Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn’t fall down as much. Unfaced insulation is just as good as faced, but it doesn’t have that paper attached to it.
