Johns Manville (JM), a Berkshire Hathaway company and building products manufacturer, adds JM Corbond Open-Cell Spray Polyurethane Foam (oc SPF) and JM Corbond Open-Cell Appendix X Spray Polyurethane Foam (ocx SPF) to its line of building insulation products. The products replace the previous JM oc SPF line and are recommended for walls, floors, crawl spaces, and unvented and vented attics and ceilings.

JM Corbond oc SPF is a two-component, low-density, nonstructural insulation system designed for commercial, residential and industrial applications. Its low-density nature allows for tremendous yield, while still affording air sealing of homes, offices and classrooms. This results in better air quality and increased comfort for building occupants.

Additionally, JM Corbond ocx SPF meets ICC Evaluation Service’s AC 377 Appendix X requirements for application without an ignition barrier in attics and crawl spaces. The basis for the Appendix X test method is NFPA 286. This eliminates an extra step and reduces the number of passes required, which saves contractors time and money while achieving the same performance level of JM Corbond oc SPF.

JM Corbond oc SPF is available throughout the U.S. and Canada. JM Corbond ocx SPF is available in the U.S. only, because it is an ideal match to building codes and climate zones.

Performance advantages of JM Corbond oc SPF and JM Corbond ocx SPF include:

  • Superior sprayability: Offers spray characteristics allowing for improved efficiency and ease of installation for contractors on jobs of all sizes.
  • Comfortable indoor environments: Stops air leakage with an effective air barrier that will not shrink or settle, which results in more consistent indoor temperature control year-round, and improves Sound Transmission Class (STC) rating to reduce noise pollution.
  • Energy efficient: Reduces heat transfer via conduction and radiation to improve thermal performance, and achieves R-values up to R-3.6 at 1 inch (JM Corbond oc SPF) and R-3.7 at 1 inch (JM Corbond ocx SPF).
  • Improved indoor air quality: Eliminates unwanted air exchange and controls moisture infiltration to decrease exposure to outdoor pollutants, allergens, dust, mildew and mold.
