Earthseal Foam .5 is foam insulation that can be sprayed onto ductwork and plenums, giving a rating of R-7. It is a renewable resource-based SPF open-cell insulation that replaces the use of petroleum-based polyols with those found in sugar cane and corn. According to the manufacturer, because of its agricultural-based content, this insulation is far more fire resistant than its petroleum-based counterparts. Earthseal Foam .5 can be used in commercial and residential applications. The insulation cures quickly to provide an airtight seal, which reduces air penetration. It is resistant to pests, will not wick up water, and is mold- and mildew-resistant.
