R-value of foam insulation.

Open-cell spray foam typically has an R-value ranging from 3.5 to 4.3 per inch, making it an excellent choice for interior applications where space allows for thicker insulation. Closed-Cell Spray Foam R-value. Closed-cell spray foam, on the other hand, is a denser material that offers exceptional rigidity and structural strength. The R-value for insulation measures how much resistance an insulation of a given thickness has against the heat flow. The unit of R-value is °F·ft²·hr/BTU/in or K⋅m²/W.
