Enter your area, thickness, and other relevant details into the calculator to determine your spray foam coverage.

Spray Foam Coverage Calculation Formula

The following formula is used to calculate the coverage from your spray foam application.

Coverage = Area * (Thickness / 12)

Variables:

  • Coverage is the total area covered by the spray foam (Sq Ft)
  • Area is the surface area to be covered (Sq Ft)
  • Thickness is the depth of the spray foam applied (Inches)

To calculate the coverage, multiply the area by the thickness divided by 12.

What is Spray Foam Coverage Calculation?

Spray foam coverage calculation refers to the process of determining the total area that can be covered by a given amount of spray foam. This involves understanding the area to be covered, the desired thickness of the foam application, and other relevant measurements. Accurate coverage calculation ensures efficient use of materials and cost-effective insulation projects.

How to Calculate Spray Foam Coverage?

The following steps outline how to calculate the spray foam coverage using the given formula.


  1. First, determine the total area to be covered based on your measurements.
  2. Next, decide on the thickness of the spray foam application.
  3. Use the formula from above: Coverage = Area * (Thickness / 12).
  4. Finally, calculate the coverage by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
