I am looking for a source for fiberglass pipe wrap.
I want to insulate the mains.
Has anyone found a good resource?

    Depends on where you live

    Around here in Boston, Homans Associates is one good company. Industry-wide, Knauf, Owens-Corning, Johns-Manville are among other good names.

    Technically what you want is mulded fiberglass pipe insulation with All-Service Jacket (ASJ).

    "Wrap" is a soft blanket type covering or a sandwich.

    There are energy code dictates based on service temperature. Steam tends to be minimum 1.5" thick for 1.5" pipe size and 2" thick for pipe sizes 2" and up to 4" pipe size as a standard.

    Not to say that it is OK to cheat, but do not use less than one inch anywhere. Go to code if at all possible but the cost does take a jump.

    Metro Supply Company has locations in New Jersey and NYC. I had a good experience with them. They also ship UPS.
