James Hardie HardieFire™ Rockwool Fire Resistant Insulation is a premium, high-density mineral wool insulation designed for demanding residential and commercial fire-rated applications. As a core component of James Hardie’s fire-rated wall systems, this insulation is essential for achieving the required Fire Resistance Level (FRL) in boundary walls and multi-residential separations.

Manufactured from stone wool, HardieFire™ is inherently non-combustible. It can withstand temperatures exceeding 1000°C, providing a vital barrier that slows the spread of flame and heat transfer. This performance is critical for meeting Australian Building Code requirements and ensuring the safety of occupants.
