Johns Manville (JM), a Berkshire Hathaway company and leading building products manufacturer, today announced the addition of JM Corbond Open-Cell Spray Polyurethane Foam (oc SPF) and JM Corbond Open-Cell Appendix X Spray Polyurethane Foam (ocx SPF) 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 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.
