Proper application of Spray Polyurethane Foam (SPF) is critical for ensuring long-term performance, safety, and compliance with building codes. This guide outlines essential practices to follow when installing SPF around sensitive components such as CPVC piping and fire sprinkler systems.
SPF must be applied in accordance with manufacturer specifications regarding pass thickness, cure times, and environmental conditions. Both closed-cell and open-cell formulations require attention to detail to avoid performance issues and prevent damage to surrounding systems.
Special precautions must be taken when applying SPF around CPVC piping and sprinkler heads. CPVC piping should be depressurized prior to application, and sprinkler heads must be carefully masked to avoid interference with operable parts. These steps help maintain the integrity of fire protection systems and prevent chemical incompatibility or overspray issues.
Following best practices not only ensures code compliance but also promotes a safe and durable insulation system within the structure.
