A frequent question from homeowners researching spray foam insulation is “How much does spray foam insulation cost?” Much like buying a car, variable factors can influence the ultimate cost per square foot of a spray foam insulation installation. Below are four things to keep in mind about the cost of spray foam insulation.

Spray Foam Type: What kind of spray foam is being used? Does the project require closed-cell insulation or an open-cell spray foam insulation be used? Open-cell spray foam insulation is more cost-effective than closed-cell and is effective in residential projects in providing thermal comfort, air-sealing, and moisture management.

Quantity: How much material will be needed to complete the job? Open-cell spray can cover more surface area than closed cell spray foam insulation. This is due to the soft, sponge-like surface that expands up to 100 times its initial volume while closed-cell can expand between 40 and 60 times its initial size when applied, meaning more material is required to cover the space. The necessary thickness of the material, dictated by the building code or area of the home, will also contribute to how much material is needed.

Labor: Remember to factor in the price of the spray foam contractor’s labor cost. Unlike painting, spray foam insulation is not a DIY project, and it requires a certified professional to apply the material.

Location/Climate: Southern climates are different from northern climates. Closed-cell spray foam is typically used in areas prone to flooding (since FEMA recognizes the closed-cell as a flood-resistant material). At the same time, open-cell is a great option for southern climates due to its ability to breathe.
