Spray Foam and cPVC Pipe: Industry Research Solves the Problem

摘要

For the past two years, several SPF insulation contractors have been frustrated when it comes to applying spray foam over cPVC piping used in sprinkler systems. A handful of contractors reported that some code officials were not permitting spray foam to be installed in contact with cPVC pipe. This was concerning, because cPVC is commonly used in residential sprinkler systems and hot water supply lines, Changes to the 2009 IRC model building code will require that all new homes use sprinkler systems beginning in January 2011 (subject to state and local adoption).
