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.
