Our take on the Owens Corning R-19 Fiberglass Insulation Roll 15 in x 96 in x 6.25 in

This is a single unfaced fiberglass insulation roll from Owens Corning, 15 inches wide, 96 inches long and 6.25 inches thick, rated R-19. It is aimed at exterior wall and floor cavities, and the unfaced format means you add your own vapor barrier rather than relying on a facing. The best new price is $669.00 at The Home Depot as of November 4, 2026, and only one store lists it new, so there is no cheaper new option to compare against right now.

Pros
  • R-19 rating suits 2x6 exterior walls in many climates
  • Unfaced roll lets you control the vapor barrier placement
  • Fiberglass also cuts sound transfer between spaces
  • Long 96-inch roll covers a full wall bay with little waste
Cons
  • Single roll only, so a whole room needs several
  • Unfaced means buying and installing a separate vapor barrier
  • Fiberglass needs gloves, goggles and a mask to handle
  • 6.25-inch thickness needs a deep enough cavity
  • Only one store lists it new, so price competition is thin

Questions and answers

Is R-19 enough for an exterior wall?
R-19 fits standard 2x6 framing and meets or nears code in many moderate climates. Check your local code, since cold climates often call for more.
Do I need a vapor barrier with this roll?
Yes. It is unfaced, so plan on a separate vapor barrier or faced product on the warm side of the wall.
How much wall does one roll cover?
One roll is 15 inches by 96 inches, about 10 square feet. A typical 8-foot wall bay takes one roll per cavity.
Can I use it in floors?
Yes, Owens Corning lists floors as a suitable application. Keep the unfaced side correct for your assembly and add a barrier where required.
Is $669 a good price?
That is the only new price listed, $669.00 at The Home Depot as of November 4, 2026, so there is no competing new price to beat it. Compare it against the per-square-foot cost of other R-19 rolls before buying.
Where is the Owens Corning R-19 Fiberglass Insulation Roll 15 in x 96 in x 6.25 in cheapest?
At The Home Depot, for $669.00, as of our latest check.
