MaterialCost/UnitBest For
Blown-In Cellulose (Standard)$1.00 - $2.00 per sq ft installedMost 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 installedHumid 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 installedExterior 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 installedNew 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 installedNew construction, below-grade walls, extremely cold climates needing maximum R-valueHighest R-value per inch, acts as vapor barrier, rigid structural improvement
