Knauf Friendly Feel® Duct Wrap with ECOSE® Technology


Description

Knauf Friendly Feel® Duct Wrap with ECOSE Technology and KwikStretch® Markings is a thermal and acoustical insulation blanket made from highly resilient, inorganic glass fibers bonded by a thermosetting resin. It is available unfaced, with a foil-scrim-kraft (FSK) jacket and with a white or black metalized polypropylene-scrim-kraft (PSK) jacket. Vapor retarders provide a 2" (51 mm) staple flange on one edge, and the factory-applied facing assures uniform quality. KwikStretch Markings on the staple flange allow for easy and accurate job site measurements.

ECOSE Technology

ECOSE Technology is a revolutionary new binder chemistry that makes Knauf Insulation products even more sustainable than ever. It is based on rapidly renewable bio-based materials rather than nonrenewable petroleum-based chemicals traditionally used in fiber glass insulation products. ECOSE Technology reduces binder embodied energy and does not contain phenol, formaldehyde, acrylics or artificial colors.

Application

Knauf Friendly Feel® Duct Wrap with ECOSE Technology 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.

Features
  • Low "k" factor significantly reduces heat gain or loss when applied with proper compression
  • Flexible
  • Lightweight
  • KwikStretch marketings on the staple flanges
  • Excellent acoustical properties
  • Tough and resilient
  • Certified for indoor air quality as a low emitting product by The GREENGUARD Environmental Institute to both the GREENGUARD Certification ProgramSM and the more stringent GREENGUARD Children and SchoolsSM standard
Benefits
  • Energy conservation, which lowers operating costs
  • System efficiency increases; energy usage/costs decrease
  • Conforms easily to flat or irregular surfaces
  • Rolls allow for faster installation, lower labor costs
  • Easier, faster measurement of stretch-out lengths
  • Reduces sound transmission through the duct wall
  • Assured condensation control when used with proper installations and sealed joints, seams and penetrations
  • Resists damage in shipment, and during and after installation
  • Carbon negative: meaning Knauf insulation products used for thermal insulating purposes recover the energy that it took to make them in just hours or a few days, depending on the application. Once installed, the product continues to save energy and reduce carbon generation as long as it is in place
Fiber glass insulation with ECOSE Technology
  • Contains three primary ingredients:
    • Sand, one of the world's most abundant and renewable resources
    • Post-consumer recycled bottle glass
    • ECOSE Technology which reduces binder embodied energy by up to 70%
