EarthWool™ Sound Control Batts

Description

Knauf Insulation’s EarthWool™ Sound Control Batts are made from highly resilient, inorganic glass fibres bonded by ECOSE^® Technology, a revolutionary new binder based on rapidly renewable bio-based materials rather than non-renewable petroleumbased chemicals. ECOSE^® Technology reduces Knauf Insulation binder embodied energy and contains no phenol, formaldehyde, acrylics or artificial colours found in traditional glasswool insulation.

Application

EarthWool™ Sound Control Batts provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The batts’ consistent quality, low dust and clean-cutting resilient fibres make fabrication easy and installation fast.

Light Commercial Applications

EarthWool™ Sound Control Batts are available in a range of thicknesses. EarthWool™ Sound Control Batts can improve Rw ratings in wood stud construction by 3 to 5 points and in metal stud construction by 8 to 10 points, depending on the complexity of the wall configuration and the thickness/density. EarthWool™ Sound Control Batts can be used for exterior and interior walls, floors, crawlspaces and a variety of ceiling applications.

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™ Sound Control 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™ Sound Control Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
EarthWool™ 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.
