Closed-Cell Polyurethane Foam


The cost of heating and cooling portion of your energy bills is rising and expected to continue to rise. According to the EPA, you can save up to 20 percent on your heating and cooling bills by adding insulation and sealing air leaks in your home. JM Corbond III closed-cell spray polyurethane foam (SPF) is one of the most effective forms of insulation. It creates a virtually impenetrable “building envelope” around the outer shell of your house, making your home more energy efficient, quieter and structurally stronger. JM Corbond III SPF also improves indoor air quality by reducing moisture accumulation.

With its superior energy savings, JM Corbond III SPF will pay for itself in the long run, making it a smart investment. Additionally, an energy-efficient, comfortable home increases resale value while making it a more enjoyable and healthy living environment.


JM Corbond III SPF is a closed-cell spray-in polyurethane foam insulation that can be installed only by a professional. Sprayed in a liquid form, it quickly solidifies and binds to the application area creating tiny foam cells that insulate. Once the foam solidifies, it forms a dense plastic air barrier that prevents outside air from infiltrating your home and conditioned air from escaping the confinements of your home. It also adds strength to your home’s structure.

JM Corbond III SPF provides an extremely high R-value,* it attains an R-21 when sprayed at a thickness of 3 inches and an R-42 at 6 inches. Not only does JM Corbond III SPF provide a great resistance to air leakage, it also provides increased protection from water vapor and outstanding noise reduction. JM Corbond III SPF and its unique Lavender color have become a symbol of uncompromising quality, performance and environmental commitment.

*R-value means resistance to heat follow. The higher the R-value, the great the insulating power.
