Open-cell foam is relatively vapor-permeable. Three inches of open-cell foam have a permeance of 16 perms. When installed in a cold climate, the interior face of open-cell SPF should be covered with a vapor retarder (for example, vapor-retarding paint). Some of the low-density foams are made in part from bio-based raw materials—for example, soybean oils—in place of a portion of the petrochemicals. Open-cell foams use water or carbon dioxide as the blowing agent.
