An insulated duct-wrap insulating product for an air duct that incorporates a wicking media to transport condensed water on the duct surface to be evaporated into the atmosphere. A wicking fabric, or fibrous media, incorporated as part of the insulating duct wrap is in contact with the metal air duct surface. A portion of the wicking fabric extends into the interior of the air duct, typically through joints in the duct system. When water vapor condenses on the air duct surface it is transported by the wicking fabric and evaporated from the wick surface within the air stream being transported by the ducting system.

Duct insulation having condensate wicking

An insulated duct assembly includes an elongated duct, an insulation blanket, at least one sheet of escape wick material and a tape layer. The insulation blanket has an inner wicking layer. The insulation blanket is applied to the elongated duct so as to create a seam aligned longitudinally with respect to the duct. The seam is defined by first and second edges of the insulation blanket. The at least one sheet of escape wick material is disposed along at least one edge of the insulation blanket. The at least one sheet of escape wick material has a &ldquo;C&rdquo; shaped cross-section surrounding the at least one edge of the insulation blanket. The tape layer is disposed along and covers the seam.
