07 Assessment
Advantages
- Excellent thermal performance with very low thermal conductivity (0.030-0.044 W/mK)
- Non-combustible per AS 1530.1 - does not contribute to fire load
- Most cost-effective insulation option in Australia ($6-12/m2)
- High recycled content (40-80% recycled glass)
- Excellent acoustic absorption (NRC 0.90-0.95)
- Wide range of R-values and sizes for all Australian climate zones
- Locally manufactured in Australia by multiple suppliers
- Lightweight and easy to handle and install in standard framing
- CodeMark certified for NCC compliance
Constraints
- Skin, eye, and respiratory irritation during handling and installation (fibres)
- Performance degrades significantly if compressed or wet
- Does not provide air sealing - requires separate vapour barrier in some climates
- Settles over time in vertical applications if not adequately supported
- Lower acoustic performance than mineral (rock) wool at same density
- Phenol-formaldehyde binder in some products (not ECOSE variants)
- Cannot be used in contact with soil or below-grade
08 Applications
A1 Residential ceiling insulation Primary thermal insulation for roof spaces in Australian homes, available from R3.0 to R7.0 to meet NCC requirements across all climate zones
A2 Wall cavity insulation Friction-fit insulation batts for timber and steel framed wall cavities providing thermal and acoustic performance
A3 Acoustic insulation Sound absorption and transmission loss improvement in party walls, floors, and ceiling cavities between rooms and dwellings
A4 Commercial building insulation NCC Section J compliant thermal insulation for commercial walls, roofs, and floors including rigid boards for ductwork
A5 Underfloor insulation Insulation batts for suspended timber floors, improving thermal comfort and reducing energy consumption
