How much does it cost to spray foam 200 square feet?

Estimating the Cost of Spray Foaming 200 Square Feet: A Comprehensive Guide

When it comes to insulating a space with spray foam, understanding the cost is crucial for effective budgeting. Whether you’re insulating a small room or a larger area, such as 200 square feet, it’s essential to have a clear idea of the potential expenses involved. In this guide, we’ll walk you through the factors influencing the cost of spray foaming 200 square feet and provide insights into estimating the overall expenses.

Factors Affecting the Cost

Before diving into the calculation, let’s consider the key factors that influence the cost of spray foaming:

  • Type of Spray Foam: As mentioned earlier, there are two main types of spray foam: open-cell and closed-cell. Closed-cell foam typically costs more due to its higher density and superior insulating properties.
  • Thickness of Insulation: The desired thickness of the insulation layer (R-Value) plays a significant role in determining the amount of spray foam required. Thicker layers will require more material, impacting the overall cost.
  • Labor Costs: Labor costs will be a significant component of the total expense. Labor rates can vary depending on factors such as location, complexity of the project, and accessibility. We pay our staff, insurance and certifications for all our employees which come in to affect with overall labor costs.
  • Additional Materials and Equipment: In addition to the spray foam itself, other materials and equipment may be needed for the installation, such as protective gear, ventilation equipment, unforeseen obstacles and application tools. We use only the best tools for the job, making sure we get you the best result every time.

Estimating the Cost

Now, let’s calculate the potential cost of spray foaming 200 square feet. To do this, we’ll need to consider the following:

  • Type of Spray Foam: Let’s assume we’re using closed-cell spray foam, which typically can cost between $1.00 to $2.50 per board foot. (Keep in mind this cost changes due to foam prices and inflation of suppliers). Thickness of Insulation: For this example, let’s aim for an insulation thickness of 2 inches.

  • Labor Costs: Labor rates can vary widely depending on factors such as location and the complexity of the project. For the purpose of this estimate, let’s assume a labor cost of $1.00 to $3.00 per square foot.


  • Calculate the Volume: Since we’re aiming for an insulation thickness of 2 inches, or 0.167 feet, the volume of spray foam needed can be calculated by multiplying the area (200 square feet) by the thickness (0.167 feet), resulting in 33.4 cubic feet.
  • Determine the Cost of Spray Foam: Using the cost range of $1.00 to $2.50 per board foot, the total cost of spray foam can range from $33.40 to $83.50 per cubic foot. Multiplying this by the volume needed (33.4 cubic feet) gives us a total cost range of $1,116.76 to $2,784.90.
  • Add Labor Costs: Assuming a labor cost range of $1.00 to $3.00 per square foot, the total labor cost for 200 square feet can range from $200 to $600 additional.
  • Total Estimated Cost Range: Combining the cost of spray foam and labor, the total estimated cost range for spray foaming 200 square feet can vary from $1,316.76 to $3,384.90.


While the cost of spray foaming 200 square feet can vary depending on several factors, including the type of spray foam, thickness of insulation, and labor rates, this estimate provides a helpful guideline for budgeting purposes.
