JM Corbond IV® Closed-Cell Spray Foam

JM Corbond® IV closed-cell spray polyurethane foam (SPF) is a next generation HFO blown, two-component, Class 1 rated, medium-density, SPF insulation system. JM Corbond IV is designed to insulate commercial, residential, and industrial buildings. The HFO technology allows JM Corbond IV to be produced with a low Global Warming Potential (GWP) and with an Ozone Depletion Potential (ODP) of zero. Its high yield, superior thermal and moisture performance, and exceptional sprayability and adhesion make it an ideal choice for high-performing energy efficient buildings.
