We Didn’t Choose Brown, It Just Came Naturally. 

Knauf Insulation Friendly Feel^® 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 and renewable resources,
• Minimum 45% post-consumer recycled bottle glass and
• ECOSE Technology

Revolutionary New 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

New Friendly Feel® 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:

• Knauf  Friendly Feel® Duct Wrap with ECOSE Technology 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.
