Whereas open-cell foam is limited in its insulation range, closed-cell foam can vary greatly in density and insulation factors.

Open cell foam typically has an R value from 2.8 to 4.1 depending on the manufacturers blend. This means its heat resistance level is lower, which can cause insulation failures in extreme temperatures. Spray polyurethane foam comes in two versions: open-cell and closed-cell.
