Our take on the CertainTeed R-19 Kraft Faced Fiberglass Insulation Roll

This is a fiberglass blanket insulation roll with a kraft paper facing on one side. The R-19 rating suits exterior 2x4 walls and other cavities where a mid-level R-value is needed. The facing acts as a vapor retarder and gives the roll a built-in flange for stapling. At $55.96 at Opentip.com as of November 4, 2026, it is the lowest of the three new prices we track.

Questions and answers

Is R-19 enough for a 2x4 exterior wall?
R-19 is a common target for 2x4 exterior walls in many climates. Check your local code, since colder zones may call for more.
Which way should the kraft facing point?
The facing goes toward the warm, conditioned side of the wall. In cold climates that means the interior; in hot-humid climates, follow local guidance.
Can I use this in a ceiling or attic?
Yes, it works in attic floors and ceilings, but the facing rules differ. In many attics the facing should not be covered or should be omitted.
How much area does one roll cover?
Coverage depends on the roll width and length, so check the roll label before ordering. Measure your wall area and add about 10 percent for waste.
Is it cheaper to buy in bulk?
Rolls are often priced per roll, and the best new price we track is $55.96 at Opentip.com as of November 4, 2026. Compare per-square-foot cost across stores before buying several.
