EarthWool Duct Wrap
Description
Knauf EarthWool® Duct Wrap is a new
generation of ‘super soft’ and highly sustainable glasswool and an
ideal solution for external duct insulation. Knauf
EarthWool® Duct Wrap is a thermal and acoustical
insulation blanket made from highly resilient, inorganic glass
fibres bonded with ECOSE® Technology. It is available
nude, or with medium or heavy duty foil facing.
Application
Knauf Insulation EarthWool® Duct
Wrap 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. Condensation
control can be achieved when the product is faced with a foil of
the appropriate duty classification.
Technical Data

1104)
Corrosion Resistance (ASTM C
665)
- No greater than sterile cotton.
Microbial Growth (ASTM C
1338)
- Does not support microbial
growth.
Surface Burning
Characteristics
- Does not exceed 25 flame spread, 50
smoke developed when tested in accordance with ASTM E 84.
Specification Compliance
AS/NZS 4859.1: 2002 Materials used in the
Thermal Insulation of Buildings and comply with the Building Code
of Australia (BCA) requirements.
Bio-solubility
Glasswool insulation fibres have been tested
in laboratory studies according to EC protocols ECB/ TM27 REV. 7,
1998 and shown to be bio-soluable. KNS3 fibres comply with the
short term biopersistence test and fulfill the requirements of
Australian and international authorities on biosolubility.
Features and Benefits
Low ‘K’ Factor
- Significantly reduces heat
gain or loss when applied with proper compression.
- Energy conservation, which
lowers operating costs.
- System efficiency increases;
energy usage/costs decrease.
Excellent Acoustical
Properties
- Reduces sound transmission through the
duct wall.
Condensation Control
- Assured condensation control when used
with foil facings, proper installation and sealed joints, seams and
penetrations.
Durability
- EarthWool™ Duct Wrap is odourless,
rot proof, non-hygroscopic, does not sustain vermin and will not
encourage the growth of fungi, mould or bacteria.
Superior Handling

ECOSE® Technology
Knauf Insulation’s EarthWool™ products with
ECOSE® Technology benefit from a formaldehyde-free
binder made from rapidly renewable bio-based materials instead of
petroleum-based chemicals which is up to 70% less energy intensive.
The technology has been developed for Knauf Insulation’s glass and
rock mineral wool products, enhancing their environmental
credentials without affecting the thermal, acoustic or fire
performance. Insulation products made with ECOSE®
Technology contain no dye or artificial colours – the colour is
completely natural.
