SPF and the net-zero energy movement

Spray polyurethane foam (SPF) is a commonly used building product with useful applications in roof system installations and insulating building envelopes. Ideal for use in residential and commercial construction, using SPF across multiple construction segments has increased steadily over time according to the American Chemistry Council's Center for the Polyurethanes Industry. SPF's high performance and energy-efficiency characteristics have contributed to its widespread adoption and use.

In roofing projects, SPF acts as a water barrier, air barrier and thermal insulator. Because of SPF's superb energy-efficiency capabilities, it has become a major force in the net-zero energy building movement that is picking up momentum across the U.S. The movement describes a push toward buildings with net-zero energy consumption. The energy consumed by a net-zero energy structure is roughly equivalent to the amount of renewable energy generated on the same site.


SPF is a lightweight material ideal for use in roofing projects when:

  • The roof deck is an unusual configuration or shape, such as a domed roof
  • A lightweight material is required
  • A slope application is required to provide controlled drainage
  • The roof substrate includes many penetrations, such as photovoltaic (PV) supports
  • The roof is being applied to a structure located in a region with extreme weather cycles
  • Maintaining the existing roof covering is desired
