  What thickness is recommended? Assume it reduces from near piping > mains > returns.

  One inch thickness is recommended unless the pipe passes into non-conditioned space such as attic or crawl space.

  Make sure it is fiberglass insulation, at least 1 inch thick. Foam rubber will be a sticky mess!!
