  • Although NFPA 285 has been part of the building code since 2000, there are still misunderstandings as to how materials and assemblies meet its requirements. This course reviews the types of continuous insulation (CI) options and discusses the advantages and challenges of several CI assemblies that pass NFPA 285.

  • Continuous insulation (ci) was introduced in the IBC (International Building Code) in 2006 as a new topic primarily in the northern tier climate zones. Over the course of the next two code cycles, continuous insulation has become part of the prescriptive path in all climate zones and for virtually all types of wall assemblies. This course examines different types of insulation materials commonly used as continuous insulation. Attributes that affect material use, installation, and performance within exterior wall assemblies are compared and discussed.

  • This course focuses on the changing energy codes and how they affect commercial wall assemblies. The new concept of continuous insulation (ci)—and how it is used throughout the codes—is discussed. The NFPA 285 fire test and its role in code-compliant wall assemblies is also discussed for commercial building types I–IV. The thermal performance, physical properties, and compliance attributes of polyisocyanurate insulation are explained, as well as how it compares with some of the other insulation options available.

  • Ponding water on a low-sloped roof can greatly reduce the performance and lifespan of the roof membrane. Tapered roof insulation systems reduce or eliminate ponding water when a roof deck does not provide adequate slope. This course describes the benefits of tapered polyisocyanurate insulation and discusses the profiles, panel repeats, and design options available. Also addressed are cricket installation guidelines, tapered roof system average R-values, and specification tips.
