4 things to remember about the cost of spray foam insulation
A common question from homeowners researching into spray foam insulation is “How much does spray foam insulation cost?” Much like buying a car, there are variable factors that can influence the final cost per square foot of a spray foam insulation installation. Below are four things to remember about the cost of spray foam insulation.
- Spray Foam Type: What kind of spray foam insulation is being used? Does the project require closed-cell insulation or can open-cell spray foam insulation be used? Open-cell spray foam insulation is more cost effective than closed-cell and is equally as effective in residential and commercial projects in providing thermal comfort, air-sealing and moisture management.
- Quantity: How much material will be needed to complete the job? Consider than open cell spray can cover more surface area than closed cell spray foam insulation. This is due to the soft, sponge like texture 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 required thickness of the material, dictated by 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. Unlike painting, spray foam insulation is not a DIY project and requires a certified professional to apply the material throughout the building envelope. Investing in a certified spray foam contractor will also provide peace of mind.
- Location/Climate: Southern climates are different to northern climates and the cost of spray foam insulation will also be affected by the location of the building. Closed cell spray foam is typically used in areas prone to flooding (since closed cell is recognized by FEMA as a flood resistant material), while open cell is a great option for southern climates due to its ability to breathe. Also consider that regional building codes may guide what product is required and how much.
For a general sense of what spray foam insulation costs, if you choose a light density product the cost can be roughly about $0.44 to $0.65 per board foot while opting for a closed-cell insulation product can cost roughly $0.70 to $1 per board foot. Again, these costs should be regarded as a guide only.
