Our take on the R-19 Unfaced Fiberglass Batt Insulation for 2x6 Walls

R-19 unfaced fiberglass batts are a standard cavity insulation for 2x6 exterior walls, fitting the 5.5-inch stud depth without compression. Unfaced batts have no vapor retarder, so they suit walls where a separate vapor barrier or house wrap handles moisture control. The R-19 rating meets common code minimums for above-grade 2x6 walls in many climate zones.

Questions and answers

Is R-19 enough for a 2x6 wall?
R-19 is the typical code minimum for 2x6 above-grade walls in moderate climates. Colder zones often call for R-20 or R-21, so check your local code before buying.
Do I need a vapor barrier with unfaced batts?
Yes, in most walls. Unfaced batts have no facing, so a separate vapor retarder or properly detailed house wrap is needed to control moisture.
Can I compress R-19 into a 2x4 wall?
No. Squeezing it into a 3.5-inch cavity cuts its R-value well below 19. Use R-13 or R-15 batts for 2x4 walls instead.
What's the difference between faced and unfaced?
Faced batts have a kraft or foil vapor retarder attached. Unfaced batts are plain fiberglass and rely on a separate barrier, which gives more flexibility in wall assemblies.
How do I cut fiberglass batts?
Compress the batt with a straightedge and slice through with a sharp utility knife. Cut slightly wide so the batt friction-fits the stud bay.
