Our take on the Certainteed R-19 Kraft Faced Fiberglass Insulation Batt

This is a single kraft-faced fiberglass batt, 15 in. wide by 93 in. long and 5.5 in. thick, rated R-19 and covering about 87 sq ft. The kraft facing gives it a built-in vapor retarder, so it suits exterior walls in stud bays where a separate vapor barrier would otherwise be needed. It is a standard-density batt aimed at the same jobs as Owens Corning and Johns Manville R-19 batts, and it is cut to fit 16 in. on-center framing. It is a commodity product: the choice comes down to fit, facing and availability rather than performance, since all R-19 fiberglass batts insulate about the same.

Questions and answers

What does R-19 mean here?
It is the batt's thermal resistance rating. R-19 is the usual target for 2x6 exterior wall cavities in most climate zones.
Does the kraft facing need a separate vapor barrier?
No. The facing is the vapor retarder. Install it toward the warm, interior side and seal the flanges to the studs.
Will it fit 16 in. on-center studs?
The batt is 15 in. wide, sized to friction-fit between studs set 16 in. on center, with room for slight compression at the edges.
How much wall does one batt cover?
About 87 sq ft, from a 15 in. by 93 in. batt. Divide your wall area by that to estimate how many you need.
Can it be used in ceilings or attics?
It can, but R-19 is low for most attic floors. Check your local code for the R-value required there before using it overhead.
Where is the Certainteed R-19 Kraft Faced Fiberglass Insulation Batt cheapest?
At Walmart, for $152.25, as of our latest check.
