| Attic | 1.52 lb/cu. ft | 1.52 lb/cu. ft | Open blow — PROFIB CELL reference density |
| Floor-ceiling | 1.87 lb/cu. ft | 2.5–3.5 lb/cu. ft | Dense-pack recommended between two storeys (acoustics + anti-settling) |
| Wall | 1.87 lb/cu. ft | 3.0–3.5 lb/cu. ft | Dense-pack in closed cavities to prevent settling |

⚠ Values of R-70 and above are extrapolated — confirm with the manufacturer before ordering.
⚠ Density below the recommended minimum for this application — risk of settling.
Based on the official PROFIB CELL coverage chart. The number of bags is adjusted in proportion to the chosen density relative to the reference density. Confirm quantities with the manufacturer for dense-pack applications.
