Fire Safety & Construction Insights

FireCrunch is produced in FIVE different thicknesses and 4 edge types: 10mm, 12mm, 16mm and 19mm TG which cover most 80-90% of all fire requirements. There are also a few different types of edges for different types of application. Sheets suit floors, walls interior and exterior, ceilings roofing and decks. To simplify this, please view the charts on the [...]

  The FireCrunch standard range of sizes is as follows:

FireCrunch has: Load bearing (steel frame FRL of 90/90/90 55Kn/ NATA LABS CSIRO NSW Load bearing (timber frame FRL of 60/60/60   NATA LABS RESOLUTE QLD on Load bearing FRL of —/120/120 more on application of additional 10mm sheet per side !!

Standard FireCrunch is a water resistant product before sealed, in that it does not retain water; if unsealed in warm weather it will release any moisture. This means that an “unsealed board will absorb some moisture in damp or wet areas” if left unsealed. You should not expect the board to hold it’s integrity if submerged in water or [...]

No. FireCrunch contains no formaldehyde, no asbestos and no toxic chemicals or CORROSIVE MAGNESIUM CHLORIDE. FireCrunch uses Magnesium Sulphate (MgSO4) being a non-corrosive element and in this regard is unique at present in Australia ( NO VOC).

Yes. Termites, one of the worst contributors to home damage, have no interest in FireCrunch, they cannot consume it and are repelled by (MgSO4) TOTAL PROTECTION FOR EXPENSIVE TIMBER FRAMING.

Yes. FireCrunch has a high sound insulation rating : Rw62 PLUS ctr NET Rw 52. FireCrunch exceeds BCA minimum requirements for airborne sound insulation between walls AS 717. See Certifications.

FireCrunch has a very high fire resistance and has been tested at temperatures up to 1200ºC for over four (4) hours and board did not ignite or pass flames) CSIRO. FireCrunch passed the following BCA ABCB AND NCC tests in 2015, re-assessed July 2020 to 2025, further re-assessed in 2025 to 2029 (CSIRO).

Yes. FireCrunch is recyclable, contains no toxic chemicals, FORMALDEHYDE, ASBESTOS OR VOC (Ask us for copy SDS or see Certifications, Australian Govt legal requirement) support@firecrunch.com.au or call 1300 933 102. FireCrunch has one tenth the carbon footprint of fibre cement plasterboard and due to the need for less repair, has less wastage. During the manufacturing process, in carbonation, FireCrunch draws [...]

FireCrunch differs from plasterboard in a number of ways in that it is: Approx. ten times stronger It won’t degrade in water* It cannot be eaten by termites so totally protects timber framing Is easier to handle and use (less chance of board damage) Can be used as both an indoor and outdoor lining Improves the thermal and sound [...]
