  • EarthWool™ is a new, advanced generation of ‘super soft‘ and highly sustainable glasswool. It is thermally efficient and cost effective in saving energy and providing increased comfort in buildings. EarthWool™ is non-combustible and also reduces unwanted noise from outside the home and limits sound transmission from room to room. Made using recycled glass bottles, sand and using ECOSE™ Technology, EarthWool™ sets a new benchmark for insulation sustainability and ease of handling.

  • EarthWool™ Wall and Ceiling Batts provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The batts’ consistent quality, low dust, and clean-cutting resilient wool makes installation fast. EarthWool™ Wall and Ceiling Batts can be used in timber and metal frame applications in residential structures. These applications include thermal and acoustical treatments to walls, ceilings and floors. Knauf Insulation offers EarthWool™ Wall and Ceiling Batts in a wide range of sizes and R-values.

  • Performance

    Thermal Conductivity

    ASTM C 518 and AS/NZS 4859.1: 2002

     

    Thermal Resistance

    ASTM C 653 and AS/NZS 4859.1: 2002

    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. EarthWool™ products made with ECOSE® Technology contain no dye or artificial colours – the colour is completely natural.

    Technical Data

    Water Vapor Absorption (ASTM C 1104)

    •  Less than 5% by weight.

    Corrosion Resistance (ASTM C 665)

    • No greater than sterile cotton.

    Microbial Growth (ASTM C 1338)

    • Does not support microbial growth.

    Fire Resistance (ASTM C 136)

    • Non-combustible.

    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.  EarthWool™ has BRANZ certification.

    Features and Benefits

    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.

    Durability

    • EarthWool™ Wall and Ceiling Batts are 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. 
    • Low dust for easier handling and increased productivity.

    Convenient Packaging, Easier Handling

    • EarthWool™ Wall and Ceiling Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
    • EarthWool™ Wall and Ceiling Batts packages feature easy to follow installation instructions.
    • Master bag batt units (containing multiple packs) ensure reduced handling costs  with improved compression – more square metres per bag, more square metres  per truck load, fewer trips to the job site and less warehouse space for storage.

  • EarthWool Material Safety Data Sheet


  • Also available from the Energy Efficiency Group is the popular Foil Faced Blanket for use under all types of metal roofing material.

    This product provides three solutions in one - the 55mm Glasswool provides bulk insulation, while the foil facing provides both reflective insulation and a condensation barrier.

    Other advantages of EES Foil Faced Blanket include;

    • Foil Facing contains a Woven Heavy Duty Scrim
    • 16kg/M3 Density. Most other products are 14kg/M3
