Cost of Spray Foam Insulation
Spray foam insulation offers an effective way to improve your property's thermal performance. Understanding the factors that influence its cost can help you plan your project efficiently and ensure you receive quality results tailored to your needs.
Larger spaces require more material and labor, increasing overall costs.
Open-cell and closed-cell foams have different prices, with closed-cell being more expensive due to its higher R-value.
Hard-to-reach areas may require specialized equipment or techniques, adding to the cost.
| Factor | Estimated Cost Range |
|---|---|
| Small attic (up to 500 sq ft) | $1,000 - $2,000 |
| Large attic (over 1500 sq ft) | $3,000 - $6,000 |
| Cavity walls | $2,000 - $4,000 |
| Exterior walls | $2,500 - $5,000 |
| Roof insulation | $2,000 - $4,500 |
The cost of spray foam insulation varies significantly based on the project's scope and specific conditions. Factors such as the type of foam chosen, the size of the area, and accessibility influence the overall expense. For larger projects, economies of scale may reduce the per-square-foot price, but complex or hard-to-reach areas tend to increase labor and equipment costs. Investing in proper installation ensures optimal performance and longevity, making it a worthwhile consideration despite the initial expenditure.
Additional costs may include surface preparation, such as cleaning or repairing existing structures, and finishing work like sealing or painting. Professional installation is recommended to ensure safety and effectiveness, which can add to the overall budget but guarantees quality results and compliance with safety standards.
Applying spray foam inside walls enhances thermal performance and reduces sound transmission, with costs typically ranging from $2 to $4 per square foot.
Attic spray foam installation generally costs between $1.50 and $3.50 per square foot, depending on thickness and foam type.
Insulating basements with spray foam usually costs $2.50 to $4.50 per square foot, offering moisture control and thermal efficiency.
