At 3.5" thick, R-13 is engineered to fill a standard 2×4 stud bay completely — no gaps, no compression. It's the most popular batt sold in the U.S. for a reason.
Beyond exterior walls, R-13 is ideal for interior partition walls where sound control matters — bedrooms, bathrooms, media rooms. Also used in retrofit projects where 2×4 framing is already in place.
Because it's the most widely used batt in residential construction, we keep deep stock of R-13. Short-lead orders and volume pricing are both available — call to discuss your project.
Tell us: R-13, batt width (15" or 23"), quantity, zip code, and delivery date. We respond same business day.
We confirm stock and send an itemized invoice with your exact delivery window — no guessing.
Delivery next business day on stocked product. Verify the order, then pay at delivery. No upfront required.
For above-grade walls in cold climates, codes typically require R-20 or higher — which means R-13 alone doesn't satisfy code for exterior walls in zones 4+. However, R-13 can be used as part of a continuous insulation assembly, or for interior partition walls, in any climate zone.
R-15 is the high-density version for 2×4 cavities — same thickness, higher density, better thermal performance. Both fit the same framing. If your spec or code requires R-15, ask about it when you call.
Yes. Kraft-faced is for exterior walls and basement walls. Unfaced is for interior walls, retrofit, and double-layer attic applications. Specify when you call.
No minimum. You can order a few bags or a few pallets. Volume earns better pricing — ask about it.
