Johns Manville Announces New JM Corbond® High Yield Open-Cell Spray Foam

JM Corbond High Yield Open-Cell offers the highest yield of any JM Corbond open-cell product. Its superior performance and exceptional sprayability make it an ideal choice for high-performing, energy efficient buildings.

JM Corbond High Yield Open-Cell insulation is a two-component, low-density, E84 Class A rated, nonstructural insulation system designed for interior commercial, residential and industrial applications. JM Corbond High Yield Open-Cell is 100% water blown and provides an R-value of 3.6 per inch.  Partnering with No-Burn, Inc. to offer their widely-accepted Plus ThB was the ideal choice for meeting interior finish requirements as an intumescent coating thermal or ignition barrier.  Plus ThB is JM’s preferred choice and the only intumescent coating providing fire protection when JM Corbond High Yield Open-Cell is sprayed.

“We’re excited to expand our line of insulation products with a high-yield spray foam insulation,” said Cassie Todtenhagen, Spray Foam Product Manager at JM. “This product is a win for installers because of its high yield and it’s a win for building owners and occupants because of its ability to improve energy efficiency.”
