Fletcher Insulation 's FI wall batts are composed of mineral wool fibres, and have been specifically designed to provide fire protection in multi-residential constructions.

Typically installed between the party wall and the roofing material, these wall batts consist of specially formulated fibres that demonstrate remarkable resistance to shrinkage at high temperatures. This ensures their suitability as a fire resistant barrier between tenancies.

Two varieties of FI wall batts are available. The first measures 168mm wide and 1,200mm long, with a thickness of 100mm. The second variety measures 200mm wide and 1,000mm long, with a 50mm thickness.

Additional beneficial properties of FI industrial party wall batts include:

  • non-combustible when tested in accordance with AS/NZS 1530.1
  • moisture-resistant; and
  • non-corrosive.
