ABSTRACT:
The shroud is formed from sheet material and is cylindrical in shape. A plurality of spacers are associated with the sheet material. These spacers are designed to engage the outer surface of a duct to hold the cylindrical sheet material in radially outwardly spaced relationship to the duct, defining thereby an insulating air gap between the outer surface of the duct and the shroud. The angular space between the spacers serves as gas channels to permit gas to flow between the shroud and the outer surface of the duct, along the length of the duct. The shroud has a straight axially extending slot along its entire length for easy removal from a duct. An axially extending edge receiving pocket is formed on the shroud adjacent the slot for receiving the adjacent longitudinally extending edge of the slot to hold the shroud in a cylindrical shape and to provide a gas-tight closure for the slot.
