Installing spray foam insulation looks dead simple, you just spray some foam and you're done.…
The cost of spray foam insulation is calculated using the measurement of board feet. If you’re trying to determine your own project cost, you’ll have want to multiply the area that you want insulated by the price per inch. This calculation looks like this: square foot x $ of insulation per sq.ft.
Depending on which section of your house you want to insulate, the cost per square foot can range between $1.25 to $6.50. Let’s assume you are renovating the first floor of your house and you want to have the exterior walls insulated which is around 800 square feet. The recommended insulation rating for above-grade exterior walls is R22 which has an estimated cost of $4.25/square foot. The total cost of having these exterior walls insulated would be 800 * $4.25 = $3,400.
