Johns Manville Corbond III closed-cell spray polyurethane foam insulation offers RSI 2.1 (R-12) at 50mm (2 inches) and can be applied in a single pass to a maximum of 89mm (3.5 inches), providing superior thermal performance with seamless air sealing and moisture control in a single step. Multiple immediate passes, with no wait time, may also be applied. With high yield and excellent adhesion, it's an ideal choice for high-performing energy efficient commercial, residential and industrial applications.
Complete Coverage: Expands and adheres without shrinking or settling.
Energy-Efficient: Reduces air and moisture infiltration to the building envelope and provides continuous coverage for high thermal performance.
Air Barrier: Prevents leaks when properly installed at 25 mm (1”) thickness or more.
Superior Moisture Performance: Resists mold growth; meets current vapour retarder codes.
Wide Application Temperature Range: Can be applied at temperatures as low as -7°C (19°F).
Faster Installation: Spray easily in a single pass from a minimum of 13 mm (0.5”) to a maximum of 89 mm (3.5”). Multiple immediate passes, with no wait time, may also be applied. See Data Sheet for complete information.
