This closed-cell, medium-density spray foam insulation is Icynene’s follow-up to ProSeal Eco, the first water-blown closed-cell spray foam. ProSeal offers an R-value of R7 per inch, allowing for a higher initial pass of 3 inches, as well as a Class II Vapor Retarder in one pass. ProSeal is also suitable for year-round use, viable in temperatures as low as 23° F.
