Standard FireCrunch is a water resistant product before sealed, in that it does not retain water if unsealed in warm weather it will release 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 exposed to multiple wet/dry processes, before use, particularly without adequate MgO sealing. Use special MgSO4 “vapour permeable Sealer” (See Recommended products). Klaas AquaCrunch S1. (Supplied by FireCrunch). FireCrunch should not be left out in the rain before sealing /priming. MgSO4 Sealer [...]

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.

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 back 90% of the CO2 used in manufacturing and makes it a virtually carbon neutral product. Any waste is just ground up and reused. Only 1% wood chip used in FireCrunch products, eliminating the destruction of millions of oxygen generating, [...]

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 insulation of your project Acoustics are Rw 62 plus ctr =net Rw52 BCA requirement Rw 50 net 90mm frame cavity using appropriate ( Mfg) insulation batts FRL 90/90/90 Is virtually fireproof (CSIRO certified).
