TradeSelect FireSark®

For use in Non-Combustible Construction
Trade Select™ FireSark® is an Extra Heavy Duty radiant barrier, designed for multi-purpose use in all roof and wall types where fire performance is a priority. The reflective foil side provides extra R-Value when installed facing an air cavity, and the non-combustible glass fabric multi-layer structure provides excellent fire and ember resistance, as well as superior strength, flexibility and durability.

Trade Select™ FireSark® is suitable for use in Non-Combustible construction in compliance with NCC Volume One C1.9(e)(vi) and Volume Two Part 3.7.1.1(f). Superior fire performance results from the choice of Non-Combustible fibreglass weave for the bulk of the material and naturally non-combustible aluminium.

Classified as a Water Barrier, and Class 2 Vapour Barrier. Trade Select™ FireSark® is a barrier to embers, radiant heat, moisture ingress, draughts and dust penetration.

Product Advantages

  • Suitable for use in Non-Combustible construction
  • Ember-proof
  • Ideal for all BAL zones to FZ bushfire-prone areas
  • Water and Air Barrier
  • Class 2 Vapour Barrier
  • 97% Reflective

Applications

Trade Select™ FireSark® is designed for use as a roof sarking and wall wrap in residential and commercial buildings in all regions of Australia. Suitable for use in Non-Combustible construction and for external wall construction in all building classes, and particularly where superior fire performance is desired. The 97% reflective foil face provides extra R-value when installed facing an air cavity.
NOTE: Water Barrier, Class 3 to 4 Vapour Permeable is required for walls in Climate Zones 6-8.

Fire Performance
Trade Select™ FireSark® is suitable for use in Non-Combustible construction in compliance with NCC Volume One C1.9(e)(vi) and Volume Two Part 3.7.1.1(f). Superior fire performance results from the choice of Non-Combustible fibreglass weave for the bulk of the material and naturally non-combustible aluminium.

Trade Select™ FireSark® Offers a Triple Crown of Safety:

AS 1530.1—1994 Methods for fire tests on building materials, components and structures Part 1: Combustibility tests for materials. The fibreglass fabric and aluminium foil have achieved a result of not deemed combustible.

AS 1530.2—1993 Methods for fire tests on building materials, components and structures Part 2: Test for flammability of materials.
FireSark® achieves a flammability index of 1 or Low (≤5)

AS/NZS 1530.3:1999 Methods for fire tests on building materials, components and structures Part 3: Simultaneous determination of ignitability, flame propagation, heat release and smoke release
The early fire hazard indices are:
Ignitability: 0
Spread of flame: 0
Heat evolved: 0
Smoke developed: 2

Bushfire Attack Levels
Trade Select™ FireSark® complies with AS 3959-2009 Construction of buildings in bushfire-prone areas for use in BAL – LOW to BAL – FZ building construction. Seek independent advice regarding the selection of sarking prior to installation in the BAL design.
