Our take on the Owens Corning 23 in W x 470 in L x 6.25 in 19 Unfaced Fiberglass Insulation Roll

This is an unfaced R-19 fiberglass insulation roll, 23 inches wide and 470 inches long, covering about 75 square feet at 6.25 inches thick. R-19 is a mid-to-high cavity value aimed at 2x6 exterior walls, floors over crawl spaces and attic knee walls. Unfaced rolls are the plain, no-vapor-barrier version, so they suit walls where a separate vapor retarder or house wrap handles moisture. Against batts, a continuous roll cuts framing gaps and installs faster on long runs; against blown-in or spray foam, it is simpler for a DIY job but leaves more air-leak paths if edges are not snug.

Pros
  • R-19 value fits standard 2x6 framing
  • Continuous roll limits seams versus short batts
  • Unfaced design lets you add your own vapor retarder
  • Light, easy to cut with a utility knife
  • Friction-fits between studs and joists
Cons
  • Fiberglass irritates skin and lungs without gloves, glasses and a mask
  • Must be cut and fitted tightly or performance drops
  • Unfaced means no built-in vapor barrier
  • Compressing it lowers the R-value
  • Rolls are bulky to move and store

Questions and answers

What does R-19 mean and where should it go?
R-19 is the insulation's resistance to heat flow. It is sized for 2x6 wall cavities, floors over crawl spaces and similar spaces about 6 inches deep.
How much area does one roll cover?
At 23 inches wide and 470 inches long, one roll covers roughly 75 square feet. Measure your cavities and add about 10 percent for cuts and waste.
Do I need a vapor barrier with unfaced insulation?
Unfaced rolls have no built-in retarder. In most cold climates you add a separate vapor retarder on the warm side of the wall, following local code.
Can I compress it to fit a smaller cavity?
No. Squeezing it into a 2x4 cavity cuts its R-value. Use the right thickness for the cavity instead.
Is fiberglass insulation safe to handle?
It is safe when handled with care. Wear gloves, long sleeves, eye protection and a dust mask, and wash exposed skin afterward.
Can it be used in ceilings and attics?
Yes, but check the required R-value for your climate. Attics usually need more than R-19, so this roll suits walls and floors better than open attic floors.
