Our take on the Knauf Kraft Faced Fiberglass Insulation Batt

Knauf Kraft Faced Fiberglass Insulation Batt is a blanket-style fiberglass batt with a kraft paper vapor-retarder facing on one side. The facing staples to studs, so it works as both insulation and a vapor barrier on walls and ceilings. It is GREENGUARD certified for low indoor emissions. The best new price is $81.20 at Hiwassee as of November 4, 2026, with four stores selling it new.

Questions and answers

Is kraft-faced insulation worth it over unfaced?
Yes, when you need a vapor retarder on an interior wall or ceiling. The kraft facing staples to the studs and saves buying and installing a separate sheet. In very cold or very humid climates, check local code first.
Can I leave the kraft facing exposed?
No. The kraft paper is flammable and must be covered with drywall or another approved finish. It also needs to face the warm side of the wall.
Does compressing the batt hurt performance?
Yes. Squashing a batt reduces its R-value, so buy the thickness that fills the cavity without pressing it down. Fluff it back to full thickness before stapling.
What tools do I need to install it?
A utility knife, a straightedge, a staple gun and safety gear: gloves, long sleeves, eye protection and a dust mask. A tape measure helps with trimming around outlets and framing.
When is the price lowest?
Insulation prices tend to dip in fall and winter, outside the spring and summer building rush. The best new price was $81.20 at Hiwassee as of November 4, 2026; compare the four stores before buying.
