JM Gen IV closed-cell spray polyurethane foam (SPF) is a next generation HFO blown, two-component, medium-density, Class 1 rated, SPF insulation system.

JM Gen IV closed-cell spray polyurethane foam (SPF) is a next generation HFO blown, two-component, medium-density, Class 1 rated, SPF insulation system. JM Gen IV is designed to insulate commercial, residential, and industrial buildings. The HFO technology allows JM Gen IV to be produced with a low Global Warming Potential (GWP) and with an Ozone Depletion Potential (ODP) of zero.

Advantages:

California Compliant: Meets HFC Reduction Requirements, zero ODP, and less than one GWP
Complete Coverage: Expands and adheres without shrinking or settling
Energy-Efficient: R-6.9 per inch
Fast Installation: Spray easily in a single pass from a minimum of .5" to a maximum of 4”. Multiple immediate passes, with no wait time, may also be applied. See Data Sheet for complete information.
Commercial Approvals: NFPA 285 assembly approvals
