About SprayFoamCalc

SprayFoamCalc is a free spray foam insulation cost calculator. You build your space in 3D, choose the surfaces to insulate, pick a foam type and thickness, and the calculator shows the spray area, the board feet of foam, and an estimated price for professional installation and for DIY materials.

Who we are

The site is run by an independent operator and published under the name SprayFoamCalc Editorial. We are not a contractor, an installer or a manufacturer, and we don't sell insulation. You can reach us at kundingwhale@gmail.com.

What the estimates are, and are not

Prices are planning estimates built from published price ranges and the DIY kit price noted on our methodology page. They are not quotes. Actual prices depend on your region, the condition of the building, access, and the installer. Always get written quotes before you commit to a job.

How the site is funded

Some links on the site are affiliate links. If you click one and buy something or request a quote, we may earn a commission at no extra cost to you. Affiliate relationships never change the numbers the calculator produces. See the affiliate disclosure for details.
