JM Corbond Open-cell
Johns Manville Corbond® Open-cell Spray Foam is a lower density, nonstructural insulation that offers an R-Value of R-3.8 per inch. It delivers high yield, minimizes sound transmission and virtually eliminates any air leakage. It's designed to improve energy efficiency for a wide variety of residential, commercial and industrial applications and can act as an effective air barrier.
Energy-Efficient: Helps to improve energy efficiency by filling in gaps and cracks while creating an air seal.
Air Barrier: Air-impermeable at 3.75”.
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 attics and crawl spaces.
