Material Options

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

Material	Cost/Unit	Pros	Cons	Best For
Fiberglass Batt Insulation	$0.50 - $1.50 per sq ft installed	Lowest cost, widely available, DIY-friendly, good R-value per dollar for rim joists	Absorbs moisture, can harbor mold if wet, not a vapor barrier, less effective on cold concrete walls	Rim joist insulation and interior stud wall cavities in dry basementsLowest cost, widely available, DIY-friendly, good R-value per dollar for rim joists
Rigid Foam Board (EPS or XPS)	$1.00 - $2.50 per sq ft installed	Moisture-resistant, adds R-value without moisture risk, can be cut to fit, some types act as vapor retarder	Requires fire protection (drywall) if left exposed, more labor to install neatly, seams need tape	Foundation wall insulation - best practice approach for most basementsMoisture-resistant, adds R-value without moisture risk, can be cut to fit, some types act as vapor retarder
Closed-Cell Spray Foam	$2.00 - $4.00 per sq ft installed	Highest R-value per inch (R-6 to R-7), complete air and vapor seal, fills gaps and irregular surfaces, longest-lasting option	Must be installed by licensed applicator, most expensive option, cannot be removed once cured, off-gassing during cure	Rim joists, irregular surfaces, and homeowners who want maximum energy performance and moisture controlHighest R-value per inch (R-6 to R-7), complete air and vapor seal, fills gaps and irregular surfaces, longest-lasting option
Open-Cell Spray Foam	$1.00 - $2.00 per sq ft installed	Good air sealing, softer and more flexible, lower cost than closed-cell, fills cavities completely	Lower R-value per inch (R-3.5 to R-4), absorbs moisture, needs vapor barrier in some climates	Interior applications where moisture is controlled and air sealing is the primary goalGood air sealing, softer and more flexible, lower cost than closed-cell, fills cavities completely
Mineral Wool (Rockwool) Batts	$1.00 - $2.00 per sq ft installed	Moisture-resistant, fire-resistant, excellent sound absorption, holds shape better than fiberglass	More expensive than fiberglass, heavier and slightly harder to cut, itchy to handle	Basements where fire resistance and sound dampening are priorities alongside thermal performanceMoisture-resistant, fire-resistant, excellent sound absorption, holds shape better than fiberglass
