This course provides architects, specifiers, and building engineers with a comprehensive overview of spray polyurethane foam insulation. Participants will learn about the features of low- and medium-density spray polyurethane foam insulation including thermal performance, physical properties, characteristics, environmental impact, economics, and resiliency. This course concentrates on the use of medium-density SPF as continuous insulation in exterior commercial wall assemblies and how SPF can provide design flexibility by adhering to common building materials and seamlessly adapting to any shape. Special attention is devoted to code compliance and wall system fire performance.
