How Much Does Spray Foam Cost Per Foot?

The overall cost of your insulation project will depend on a few factors, such as the size of your home, the area you’re insulating, etc. — but we can give you a general idea.

Spray foam (also known as polyurethane) is typically calculated by the board foot. To calculate the board footage of the space you need to insulate, multiply the area you want to insulate by the depth in inches.

In general, open-cell spray foam is 35 to 55 cents per board foot, and closed-cell spray foam is $1–$2 per board foot.

To get an estimate on how much new home insulation would cost, here’s an example:

  • 3,000 board feet of space at 0.50 = $1,500

Remember, this is just a general example and may not necessarily be accurate for your specific project. If you’d like to get an estimate for your Washington, DC-area home, an Accurate Insulation professional can assess your space.

How Much Insulation Does Your Home Need?

Color-coded map of U.S. showing R-value zones.

How much insulation your home needs depends on the R-value your home requires, where you’re installing the insulation and what kind of insulation you’re using. Spray foam has a high R-value, making it extremely efficient.

Maryland is in Zone 4, which requires R-values of R-38 to R-60 for attics, R-13 to R-15 for walls and R-25 to R-30 for floors. If you’re adding new insulation over old, you might not need as high of an R-value. Your insulation contractor will make sure your home has the appropriate amount of insulation to meet these R-value requirements.
