Faced or unfaced insulation in attic floor.

This is usually kraft paper but sometimes other types of paper can be used. Unfinished or uninsulated attics need a layer of protection against air migration. Install batting between the attic s floor joists. To this end you insulate your home.

When adding more insulation to an attic that already has insulation use unfaced insulation. The same is true for an attic floor. If the attic doesn t have any existing insulation use faced insulation with the paper facing toward the heated living space. Unlike unfaced insulation faced insulation has a vapor retarder that keeps moisture out.

In crawl spaces unfaced insulation is generally only used when adding to existing insulation. It s important not to lay faced insulation on top of faced insulation. Among the many insulation options available for the homeowner there is one that stands above the rest. Paper faced insulation means that one side of the insulation material comes lined with paper.

Unfaced insulation is just insulation without an attached moisture barrier. More often than not faced insulation is made out fiberglass. The facing should aim down toward the living space. If you re using unfaced insulation in an area where a vapor barrier is required or recommended you may be able to add your own barrier using plastic sheeting.
