Climacoustic External Duct Wrap (Faced)

FF Duct Wrap

Climacoustic® External Duct Wrap (Faced) is a thermal and acoustical insulation blanket made from highly resilient, inorganic glass fibers bonded with ECOSE® Technology. It has a foil-scrim-kraft (FSK) facing.


Climacoustic Duct Wrap (Faced) is used as external insulation on commercial or residential heating or air conditioning ducts.

It is suitable for the exterior of rectangular or round sheet metal ducts and spaces or surfaces where temperature and condensation must be controlled.

Proven Performance

  • Preferred by professional installers concerned with quality, appearance and  productivity.
  • Excellent acoustical properties reduce sound transmission in the home when  properly installed in walls, ceiling and floor systems.


  • Climacoustic External Duct Wrap is odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Superior Handling

  • Highly resilient insulation recovers quickly to full thickness for a snug fit and superior finished aesthetics.
  • Consistent quality materials feel good, cut easily and install fast. 
  • Low dust for easier handling and increased productivity.

Convenient Packaging, Easier Handling

  • Climacoustic External Duct Wrap is packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
  • Climacoustic External Duct Wrap packages feature easy to follow installation instructions.
  • MasterBag batt units (containing multiple packs) ensure reduced handling costs with improved compression – more square metres per bag, more square metres per truck load, fewer trips to the job site and less warehouse space for storage.
