Material prices below are national averages; availability in Las Vegas may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Blown-In Cellulose (Standard)	$1.00 - $2.00 per sq ft installed	Recycled content, excellent air-sealing properties, R-3.5/inch, fire-treated, widely available	Can settle slightly over time (dense-pack minimizes this), heavier than fiberglass	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	Does not settle, moisture-resistant, R-2.2-2.7/inch, lighter than cellulose	Slightly lower R-value per inch than cellulose, less effective air sealing	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	Higher density (3.5 lbs/cubic ft) virtually eliminates settling, better air sealing than standard blown-in	Requires specialized equipment and experienced installer, slightly more expensive	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
Open-Cell Spray Foam (R-3.7/inch)	$2.00 - $3.50 per sq ft installed	Excellent air sealing, fills irregular cavities completely, soft and flexible	Requires removal of existing drywall for application (open-wall install), expensive retrofit	New construction or gut renovations where walls are already openExcellent air sealing, fills irregular cavities completely, soft and flexible
Closed-Cell Spray Foam (R-6.5/inch)	$3.00 - $5.00 per sq ft installed	Highest R-value per inch, acts as vapor barrier, rigid structural improvement	Very expensive, not practical for closed-wall retrofit, off-gassing during install	New construction, below-grade walls, extremely cold climates needing maximum R-valueHighest R-value per inch, acts as vapor barrier, rigid structural improvement
