Efficacy of High Lift Spray Foam Insulation

As project timelines get tighter, it can be tempting to specify insulation materials, like high lift spray foams, that help expedite the installation process. High lift foams allow the installer to apply the material in a single, thick pass, theoretically saving time during the installation. However, recent research has revealed that this installation method may have some flaws that impact the short-term and long-term performance of the insulation.

This white paper covers:

• Exotherm evaluation of JM Corbond III and pass thickness recommendations for spraying in immediate, successive passes
• Application time study
• Core density comparison
• Dimensional stability comparison
• Recommendations to ensure installation integrity
