In Reply to: Fiberglass Insulation on Steam Pipes/Main Vents? posted by Ryan on November 16, 2005 at 17:55:11:
Fiberglass insulation of the type you describe could be used and then wrapped and banded with aluminum flashing.
Vents to eliminate air from the mains where needed is a benefit. Don't put them right at the end where they can be slammed, though. Put the vents a foot and 1/2 from the ends and up on 8-inch-long pipes if you can, to keep water from slamming them.
