The improved insulative performance of ThermaSilver® comes from minute particles of graphite mixed with EPS that act as infrared reflectors that considerably reduce thermal conductivity.

This means that builders and designers seeking to achieve the six star energy rating can get vastly improved insulation performance with the same board thickness or conversely, achieve the same energy rating as normal EPS using a thinner board.

Unique Silver-Grey Colour

The unique silver-grey colour identifies ThermaSilver®. Producing thinner panels consumes fewer resources and when coupled with more efficient insulation, that will last the life of a building, means ThermaSilver® is a better environmental choice than other insulation systems.

ThermaSilver® is exclusively manufactured by RMAX, Australia’s leading producer of environmentally friendly EPS products, using BASF Neopor® technology.


BAL Bush Fire Attack Level.


After the Canberra bushfires in 2003, the Australian Standard relating to building was reviewed and a new Australian Standard (AS 3959) was introduced nationally in 2009. 

The new building standard has six risk levels (Bushfire Attack Levels-BALs). There are increasing construction requirements that range from ember protection at the lower levels to direct flame contact protection at the highest. The new building standard increases the construction requirements on residential buildings so they are better bushfire protected.

Products used in external construction of houses should have a BAL rating ensures that building is undertaken in such a way that risk to people and property is minimised. 

It is a requirement that a person or organisation who has suitable qualifications and experience undertakes the BAL assessment. RMAX commissioned EXOVA Warringtonfire, a NATA accredited testing authority, specialising in BAL testing and certification to undertake their BAL 29 conformance testing. 

To meet the BAL 29 conformance requirements as tested by EXOVA Warringtonfire, RMAX Orange Board render must be used and applied at a minimum thickness of 8mm.

PLEASE NOTE: The use of any render system other than the RMAX Orange Board render, applied at minimum thickness of 8mm, may meet the requirements of the BAL 29 certification. 

It would be expected that similarly formulated render products would deliver the same test results however RMAX has not tested other render systems.
