The workhorse batt for interior work.

01

Interior partitions and sound walls

R-11 is the standard spec for interior partition walls where thermal performance is secondary to sound attenuation. Hotels, multifamily, office spaces — anywhere you need to deaden sound between rooms without full mineral wool cost.

02

Retrofit and remodel work

R-11 is easy to cut, handle, and install in tight retrofit conditions. It's the go-to for remodel contractors adding insulation to existing 2×4 framing without disturbing interior finishes.

03

Unfaced for interior applications

Unfaced R-11 meets code for interior partitions in most jurisdictions — no vapor retarder required for non-exterior assemblies. Stocked in both faced and unfaced; specify when ordering.

Common questions.

When do I use R-11 instead of R-13?

R-11 is typically used for interior partition walls (sound, not thermal) or in mild climates where R-11 meets the code minimum. For exterior 2×4 walls in most U.S. climate zones, R-13 or R-15 is required.

What widths do you stock for R-11?

We stock 15" (for 16" OC framing) and 23" (for 24" OC framing) in both kraft-faced and unfaced. Specify when ordering.

Is there a minimum order?

No minimum. Order any quantity that fits your job. Volume pricing is available — ask when you call.
