  • FireCrunch will not ignite from ember attacks. Ember attack is the largest single national contributor to home loss in bushfires.

  • FireCrunch is eight to ten times stronger than normal plasterboard products and is an interior exterior lining cladding board, which insulates from intense heat and cold when combined with suitable Australian climate zone insulation and fire batts.

  • FireCrunch will not swell or shrink in high variable and low variable temperatures will not swell in water so, once sealed is very ideal for use flood prone areas.

  • FireCrunch is of no interest to insect pests and termites and bacteria and mould will not grow on the board. FireCrunch is termite proof and protects all timber framing.

  • FireCrunch building board interior, exterior, wet areas product has been fire tested and assessed by the CSIRO to BCA standards to FRL 90/90/90 55kN.


  • BCA Volume One 2014: C1.8 Lightweight Construction, C1.10 Fire hazard properties and C1.12 non-combustible components, including state variations for NSW plus National Fire Test AS1530.4 (C1..C19)-/ 2025

  • BCA Volume Two 2014: Part, Fibre Cement Planks and Weatherboard Cladding. BCA Volume Two 2014: Part, Fibre Cements Sheet Wall Cladding.

  • BCA Volume Two 2014: Part, Eaves and Soffit Linings.

  • BCA Volume Two 2014: Part 3.7.1, Fire separation for FRL, including state variations for SA (refer to limitation).

  • BCA Volume Two 2014: Part 3.7.4, Bushfire areas to Part and, including state variations NSW, QLD, SA and TAS.

  • Group 1 Fire Rating from the CSIRO.
    AS/NZS 3837 (BCA) being the highest fire tested (Group 1) product.


  • FireCrunch has been tested by the NATA Labs for bush fire maximum BAL FZ AS 1530.8.2 plus FRL from 30/30/30 to 90/60/60 Glasswool batts and FRL 90/90/90 with mineral wool and rock wool batts.

  • FireCrunch has additionally been subjected to the most powerful and aggressive fire test under the BCA that of AS1530.4 (C1..C19)-/ 2025 on a 3m x 3m steel frame 1.0 BMT rising rapidly to 1200⁰C in a furnace test over a 98 minute period without flame out or board failure FRL 90/90/90 (55kN). Test report available.

  • FRL requirements over 90/90/90 under DTS/NCC should be directed to FireCrunch on 1300 933 102 or

  • FireCrunch has been tested to 1200°C with no combustion or flame out.

  • FireCrunch does not retain water; therefore, superheated steam will not "blow out" the product as it may do with standard building bricks in (BAL) fire storm conditions.

  • FireCrunch is completely fire resistant. It will not burn in a fire storm. FireCrunch is applicable in BAL 12.5 to 40 and BAL FZ, Flame Zone BAL 50Kw /m2 regulation areas and meets the AS 3959 requirements when used to protect exposed timber framing eaves joists etc., under AS/NZ 3837 materials.

  • FireCrunch insulation properties will protect internal furnishings in the home from internal combustion and ember attack if also used on doors and window shutters, and prevent flash burning from high external temperatures.
