Why Uninsulated Ducts Cost More in Georgetown Attics
Fiberglass duct insulation wraps the exterior of rigid duct or reinforces the R-value of flex duct jacketing, and its job is preventing heat transfer between the conditioned air inside the duct and the extreme temperatures of the space the duct passes through, most commonly a Georgetown attic that regularly hits 130 to 150 degrees in summer sun. Without adequate insulation, a duct carrying 55 degree supply air through a 140 degree attic gains heat continuously along its entire length, meaning the air arriving at the register is measurably warmer than what left the coil, forcing the system to overcool the air at the source to compensate, which wastes energy and can leave rooms at the end of long duct runs perpetually underserved.
We install fiberglass duct wrap in thicknesses matched to current energy code requirements for the application, typically R-6 or R-8 for supply ducts in unconditioned attic space, with a foil-faced vapor barrier oriented correctly to the exterior of the insulation layer. Vapor barrier orientation matters more than people often realize, since installing it backward traps moisture inside the insulation rather than blocking it from the outside, which degrades the insulation's effectiveness over time and can lead to mold growth within the wrap itself. We wrap the insulation snugly without compressing it excessively, since compressed fiberglass loses much of its insulating value, and seal all seams in the vapor barrier with foil tape to maintain a continuous moisture barrier along the full duct run.
This service comes up most often in older Georgetown homes where original duct insulation has degraded, compressed, or fallen away from the duct surface after years in attic heat, and in situations where insulation was simply inadequate for current energy code standards at the time of original installation, which was common in homes built before energy code updates in the 2000s tightened these requirements. We also install insulation on any newly fabricated or replaced duct sections as standard practice, since leaving new metal duct uninsulated in an attic negates much of the benefit of the repair or replacement itself. Insulation installation typically runs 500 to 1,500 dollars depending on the length of duct run and whether it is a full re-wrap or supplementing existing insulation that is only partially degraded.
