Material prices below are national averages; availability in Las Vegas may shift costs slightly.
| Material | Cost/Unit | Best For |
|---|---|---|
| Blown-In Cellulose (Standard) | $1.00 - $2.00 per sq ft installed | Most retrofits - the default choice for drill-and-fill wall insulationRecycled content, excellent air-sealing properties, R-3.5/inch, fire-treated, widely available |
| Blown-In Fiberglass (Standard) | $1.00 - $2.00 per sq ft installed | Humid climates where moisture management is a concernDoes not settle, moisture-resistant, R-2.2-2.7/inch, lighter than cellulose |
| Dense-Pack Cellulose | $1.50 - $2.50 per sq ft installed | Exterior walls where settling would reduce performance, high-performance retrofitsHigher density (3.5 lbs/cubic ft) virtually eliminates settling, better air sealing than standard blown-in |

| Closed-Cell Spray Foam (R-6.5/inch) | $3.00 - $5.00 per sq ft installed | New construction, below-grade walls, extremely cold climates needing maximum R-valueHighest R-value per inch, acts as vapor barrier, rigid structural improvement |
