Atmosphere™ Duct Wrap

Atmosphere™ Duct Wrap

Knauf Insulation Atmosphere™ Duct Wrap with ECOSE® Technology sets a new industry benchmark for sustainable, high-performance, cost-effective insulation solutions.

To create the next generation of sustainable insulation, we combined:

  • Sand, one of the world’s most abundant resources,
  • Minimum 61.9% post-consumer recycled bottle glass and
  • ECOSE Technology

ECOSE Technology

The natural brown color comes from ECOSE Technology, a revolutionary, more sustainable binder.

  • Patented technology born from five years of intensive research and development.
  • Based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals commonly used in our traditional fiber glass insulation products.
  • Does not contain phenol, formaldehyde, acrylics or artificial colors.
  • Reduces binder embodied energy by up to 70%, and global warming Potential (GWP) and total insulation
  • embodied energy by an anticipated 4% to reduce our carbon footprint.
  • Converts natural, rapidly renewable organic materials into a totally inert polymer for superior environmental sustainability.

Great Performance Benefits

Atmosphere Duct Wrap with ECOSE Technology meets all the specifications and performance requirements for your projects.

Excellent Acoustical Barrier

  • Reduces sound transmission through the duct wall of noise generated by air turbulence and mechanical equipment for quiet, efficient air delivery

Conserves Energy

  • Low “k” factor significantly reduces heat gain or loss.
  • Lowers operating costs—increases system efficiency and reduces energy usage.

Controls Condensation

  • FSK or PSK facings assure condensation control with proper installation and sealed joints, seams and penetrations.

Great Appearance

  • White and Black PSK facings are a desirable solution for exposed duct work because of their appearance and resiliency.

Applications:

  • Atmosphere Duct Wrap is a thermal and acoustical insulation blanket bonded with ECOSE Technology for use as an external insulation on commercial or residential heating or air conditioning ducts.
  • Suitable for the exterior of rectangular or round sheet metal ducts and spaces and surfaces where temperature and condensation must be controlled.
  • Ideal for cooling, heating or dual temperature service.
