Spray Foam Insulation
Johns Manville has added JM Corbond® Open-Cell Spray Polyurethane Foam (oc SPF) and JM Corbond® Open-Cell Appendix X Spray Polyurethane Foam to its complete line of building insulation products. The new products replace the previous JM oc SPF line and are recommended for walls, floors, crawl spaces and both unvented and vented attics and ceilings.
JM Corbond oc SPF is a 2-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 United States and Canada. JM Corbond ocx SPF is available only in the United States, as 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 spray-ability, energy efficiency and improved indoor air quality, among others.
