What is Duct Insulation?

Insulating jacket on duct running through an attic or crawlspace. Where it is thin or has fallen away, cooling capacity is lost on the way to the room, and the duct surface can drop below the dew point and sweat — which soaks the insulation and keeps it wet. In a North Texas attic both effects are significant through the summer.
