Understanding the Cost of Spray Foam Insulation
Open-cell and closed-cell spray foam have different costs based on density and R-value.
The size and accessibility of the space impact installation costs.
Complex shapes or hard-to-reach areas may increase labor costs.
| Factor | Average Cost |
|---|---|
| Material (per board foot) | $0.50 - $2.00 |
| Labor (per hour) | $50 - $100 |
| Application area (per square foot) | $1.00 - $3.00 |
| Thickness of insulation | $0.20 - $0.50 per inch |
| Project size (total cost) | $1,000 - $10,000+ |
| Preparation work | $200 - $1,000 |
| Additional features (e.g., vapor barriers) | $100 - $500 |
| Permitting and inspection | $100 - $500 |
Applying spray foam inside walls enhances thermal performance and air sealing, with costs varying based on wall thickness and accessibility.
Attic spray foam insulation offers high R-values, with costs influenced by attic size and existing structures.
Insulating basements with spray foam can improve energy efficiency, with costs affected by basement size and condition.
