That depends if your installation needs to meet the requirements of NFPA 13, NFPA 13R, or NFPA 13D. NFPA 13 is the most stringent and requires full attic protection and the CPVC piping must be protected. I believe you must use the special application sprinklers and insulate the pipe in order to meet the listing requirements.
