John Manville's complete line of spray polyurethane foam (SPF) insulation solutions provides superior thermal energy efficiency, as well as advanced air and sound control. SPF insulation completely covers gaps and voids, works in hard-to-insulate areas and can exceed the performance of traditional fibreglass insulation. Both Johns Manville SPF product categories, open-cell and closed cell, deliver high yield, superior performance and exceptional sprayability.
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 25mm (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 13mm (0.5”) to a maximum of 89mm (3.5”).
