PPI releases technical document on applying spray foam insulation on and around plastic pipes
A new technical document that addresses techniques for the safe and proper use of spray polyurethane foam insulation on and around plastic pressure pipe materials has been published by the Plastics Pipe Institute, Inc. (PPI) with input from the Spray Polyurethane Foam Alliance (SPFA).
Prepared by PPI’s Building & Construction Division, PPI TN-69 Recommendations when Applying Spray Polyurethane Foam Insulation on and around Plastic Pressure Pipes & Fittings discusses the proper application of spray polyurethane foam insulation to avoid damage due to heat generated by the foam. Pipe and fitting materials include CPVC, PEX, PEX/AL/PEX, PE-RT, PP-R, PP-RCT, PSU, PPS, PPSU, and PVDF.
