JM Corbond Open-cell Appendix X
Johns Manville Corbond® Open-cell Appendix X Spray Foam provides an R-Value of R-3.7 per inch, and meets AC 377 NFPA 286 Appendix X requirements for application without an ignition barrier in attics and crawl spaces. This low-density, nonstructural insulation allows for high yield while prodiving excellent heat, air and sound control. Recommended for use in residential, commercial and industrial applications.
Energy-Efficient: Helps to improve energy efficiency by filling in gaps and cracks while creating an air seal.
Air Barrier: Air-impermeable at 3.5”.
Sound Transmission: Performs well acoustically when used in an assembly.
Installation: Provides high yield with superior sprayability at an exceptional value and low odor. Meets requirements for application without an ignition barrier in attics and crawl spaces.
