Enter the area and the thickness to see board feet of foam and the approximate R-value for open-cell and closed-cell.
These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual materials, depths, access, local rules and conditions. Only a site visit can confirm what a project needs, and we give you a written scope and price before any work begins.
