JM Corbond Open-Cell - Canada - Spray Foam Insulation

Johns Manville Corbond Open-Cell Spray Foam is a lower density, nonstructural insulation that offers RSI 0.63 (R-3.6) at 25mm (1 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.

Advantages
Energy-Efficient: Helps to improve the energy efficiency by filling in gaps and cracks while creating an air seal.
Air Barrier: Expands 120 times its volume to seal voids, gaps and crevices. Air-impermeable at 95.25mm (3.75”).
Sound Transmission: Performs well acoustically when used in an assembly.
Adhesion: Exceptional when properly installed.
Installation: Provides high yield with superior sprayability at an exceptional value. Meets requirements for application without an ignition barrier in unoccupied and unvented attics when properly installed.
