|Residential (13D) Sprinkler Insulation|
I find in reading NFPA 13D that it has prescriptive ways to insulate the pipes in the attic. In talking with a plumber who claims to be well read with the standard, he says they use standard snap on pipe insulation (styrofoam tube with a slit cut to put on pipe).
In talking with a fire protection engineer, he said that in his opinion this would not be a satisfactory means of assuring the pipes would not freeze.
This is my question. Do you know somebody who is truly an expert?
I do not want to think the standard is the only way folks are doing these installations and would like to get a couple of 'expert' opinions on it.
