What does unfaced mean?

The roll has no paper or foil backing. You place it in the cavity and add a separate vapor barrier where your local code calls for one.

Attics, ceilings, interior walls and other framed cavities. It also works over existing insulation to add depth.

Do I need a vapor barrier with it?

In many cold-climate walls and ceilings, yes. Check local building code; attics and interior sound walls often go without one.

Use a sharp utility knife against a straight edge, or compression-cut with a board pressed into the roll. Wear gloves, eye protection and a dust mask.

Is it safe to handle?

Fiberglass can irritate skin, eyes and airways. Cover skin, wear glasses and a respirator, and ventilate the space while working.

Our take on the Guardian Knauf Standard Unfaced Roll Fiberglass Insulation - Single Pack

This is a single roll of unfaced fiberglass insulation from Guardian, sold under the Knauf name. Unfaced rolls have no paper or foil facing, so they are stapled in place or laid between framing and covered with a separate vapor barrier where code requires one. That makes them a fit for attics, interior walls and sound-dampening jobs rather than finished basement walls. Compared with faced batts, unfaced rolls are simpler and more flexible to place but give up the built-in vapor retarder.
