OXYMAG FLOOR BOARDS FREQUENTLY ASKED QUESTIONS
The primary reason is that OxyMag boards are reinforced with 6 layers of fibreglass mesh – 3 layers on either side of the board.
This is why a 16mm OxyMag board can be used to replace a 19mm fibre cement board; similarly, a 19mm OxyMag board can be used to replace a 22mm fibre cement board.
This was correct of chloride-based MgO cement boards in high humidity areas. OxyMag boards are made of the latest generation of non-chloride MgO cement (ie: magnesium oxysulphate (or MOS) cement). The University of the Sunshine Coast conducted a research project in which they compared the characteristics of various chloride MgO boards, a non-chloride MgO board and a fibre cement board. In their report, they concluded that while chloride MgO boards caused corrosion at high humidity levels, the non-chloride MgO board “performed similarly to the FC (fibre cement) board in the high humidity environment”.
OxyMag boards are sourced from China. Please note:
- Prior to finalising our source factory, we inspected about thirty MgO board factories in China. The partner with whom we have secured a long-term contract was head-and-shoulders above all other factories in terms of production capability, quality control and integrity.
- Our agents in China inspect and submit a thorough report of each and every consignment prior to despatch from the factory
- Pre-COVID, we visited and inspected our source factory at least twice a year. This will re-commence post-COVID.
Yes, they are. They have been tested and certified as non-combustible to AS 1530.1.
AS 1530.4 states that horizontal separating elements are tested to heating from the underside.
Accordingly, in a horizontal floor-ceiling system, the most important element to protect the frame/joists and, thus, the entire system from destruction by fire, is the ceiling. The floor boards, since they are on top of the joists and the fire/heating is from the underside, will not protect the joists (no matter how great their fire resistance).
Thus, testing floor boards for an FRL rating in accordance with AS 1530.4 is essentially pointless.
OxyMag floor boards only contain trace elements of crystalline silica. In contrast, fibre cement boards contain up to 60% crystalline silica and, thus, represent a health hazard when inhaled as dust particles.
