A lower density, nonstructural spray foam, Johns Manville Corbond® Open-cell Appendix X Spray foam delivers incredible yield while providing air isolation, R-value and acoustical performance.

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.

ADVANTAGES:
Energy-Efficient:
Reaches R-3.7 when installed 1” thick.
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. Meets requirements for application without an ignition barrier in unoccupied and unvented attics and crawl spaces.
