James Hardie™ cladding, weatherboards and building facades are made from fibre cement which is deemed as a non-combustible material in accordance with C1.9 and part 18.104.22.168 of the National Construction Code.
All James Hardie™ and Scyon™ cladding and weatherboards (6mm thick or greater) can be used in bushfire prone areas to help resist bushfire attack from burning embers, radiant heat and/or flame contact as part of Australian Standards AS 3959-2009 Construction of Buildings in Bushfire Prone Areas.
When installed and maintained correctly, in accordance with James Hardie's published manuals at the time of installation, James Hardie warrants its products to be resistant to rotting, fire, impact, moisture damage and termites.
The following FAQ’s are designed to provide clarity regarding the fire performance characteristics of James Hardie™ and Scyon™ cladding products.
- Do James Hardie™ fibre cement products contribute to the spread of fire?
No. James Hardie™ fibre cement products are deemed non-combustible in accordance with the National Construction Code; they will not contribute to the spread of fire. Additionally, James Hardie™ fibre cement achieves a ‘0’ Flame Spread result (on a scale of 0 to 10 with ‘0’ representing the best possible result) when tested in accordance with AS/NZS 1530.3. Under this test the material also achieves ‘0’ for ignitability and heat evolved, and ‘0-1’ for smoke developed.
- Are James Hardie™ and Scyon™ cladding products suitable for use in applications where non-combustible materials are required?
Yes. All James Hardie™ and Scyon™ fibre cement products are suitable for use where non-combustible building materials are required.
For residential buildings covered by Volume 2 of the National Construction Code, clause 22.214.171.124 specifically indicates that fibre cement is suitable for use where non-combustible materials are required.
For residential and commercial buildings covered by Volume 1 of the National Construction Code, clause C1.9 similarly indicates that fibre cement is suitable for use where non-combustible materials are required.
How do James Hardie™ and Scyon™ cladding products meet the fire resistance requirements of the Australian National Construction Code?
Fire Resistance Levels or ‘FRL’ rating are measured in accordance with AS/NZS 1530.4. This method of testing is based on a full system as opposed to individual system components. James Hardie™ and Scyon™ cladding products have been tested in multiple wall system configurations to determine the respective FRL of each system.
