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.
