Spray foam prices per board foot
Spray foam is priced by the board foot: one square foot, one inch thick. Multiply the area by the thickness to get board feet, then by the price per board foot.
| Foam type | Typical price per board foot | Notes |
|---|---|---|
| Open-cell | About $0.45 to $0.90 | Common on attic roof decks; lower cost per inch |
| Closed-cell | About $1.00 to $2.20 | Under floors, crawl spaces, metal buildings; resists moisture |

Spray foam insulation questions
Why is closed-cell foam more expensive?
It's denser, uses more chemical per inch and has a higher R-value per inch.
Is there a minimum charge for spray foam?
Many installers have a minimum because of setup time for the spray rig. Small jobs cost more per square foot.
