As the net-zero energy building movement has gained momentum across the U.S., spray polyurethane foam (SPF) has been widely adopted for use in residential and commercial construction. SPF acts as a water barrier, air barrier and thermal insulator in roofing projects, and its high performance and energy-efficiency characteristics make it an ideal product for buildings designed to achieve net-zero energy consumption.
