FireCrunch is made up of a combination of primarily Magnesium Oxide (MgO) and special non-metal corrosive magnesium sulphate Magnesium Sulphate (MgSO4)


FireCrunch is made up of a combination of primarily Magnesium Oxide (MgO) and Magnesium Sulphate (MgSO4) This has been bonded with a small percentage of organic and IP composite materials, strengthened with fibre mesh.

MgSO4 is a new development in the FCA range and replaces Mag chloride ( MgChl2) with Mag sulphate and eliminates all metal corrosion, a common problem with ordinary MgO chloride boards (MgChl2).

What is Magnesium Oxide?

MgO or Magnesium oxide (sometimes called magnesia), is an absorptive solid mineral, white in colour, that occurs naturally in metamorphic rocks and is sourced from magnesium mining. Magnesium oxide is a waste by product of external use process in steel manufacturing .

ENVIRONMENTAL — FCA is 100% better

FireCrunch is produced by the addition of magnesium sulphate to the mag oxide and lime followed by a heat process using low CO2 kiln temperatures, 50% LESS than plasterboard products, so 50% less CO2.

During the carbonation process of manufacturing, FireCrunch draws back 90% of the 50% CO2 created to produce FCA and makes it a virtually carbon neutral product!

Further, FCA eliminates the “additional destruction“ of millions of oxygen producing trees each year to manufacture weak ineffective low R value insulation, paper lined plasterboard and protecting them from termites, floods and fire!
