Climacoustic Internal Duct Liner Roll

InternalDuctWrapClimacoustic® Internal Duct Liner roll is a flexible, insulation bonded with ECOSE® Technology.

It is faced with a tightly bonded woven tissue to give the airstream a smooth, tough surface, resisting damage during installation and operation.

The encapsulant edge coating eliminates airstream flaring.


Specifically designed as an interior insulation material for sheet metal ducts used in heating, ventilating and air conditioning.

Provides an optimum combination of efficient sound absorption, low thermal conductivity and minimal airstream surface friction.

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 Internal Duct Liner roll 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.
