Icynene-Lapolla’s OC-450 and OC-1350 open-cell spray polyurethane foam (SPF) insulation are two sizes of the same low-pressure, low-density, two-component SPF. OC-450 covers a maximum 450 board feet and OC-1350 covers 1,350 board feet. The open-cell SPF provides R-4.3 applied at 1-inch thickness. It fills and seals voids and surfaces, and creates air barriers.
