Of all the different insulation options available today in commercial construction, spray foam can provide outstanding thermal performance while also contributing to air sealing, moisture control, and even structural integrity. This learning unit will provide an overview of spray foam insulation, how it differs from conventional insulation types, its most appropriate applications, and how the material is allowed to be used in fire-resistant construction.

Learning Objectives

  • Explain the benefits of and the differences between open-cell spray foam insulation and closed-cell spray foam insulation.
  • Describe the most appropriate applications for open-cell and closed-cell spray foam in commercial designs.
  • Discuss how spray foam insulation can be used in assemblies requiring fire resistance.
  • Define the differences between thermal barriers and ignition barriers, and explain insulation fire ratings.
