When you are looking for external cladding panels in Australia you cannot go past ThermaWallPlus®. The ThermaWallPlus® insulation core is made from high quality Expanded Polystyrene (EPS) pre-finished with an enhanced coating system and reinforced with fibreglass mesh for strength.

The EPS used is treated with Perform Guard®, an inorganic material that is a deterrent to termites. It provides fully integrated protection for the life of the external wall cladding products used in a building's construction. It is not a surface additive.

How the render panel insulation works

Heat flow is restricted from passing through the panels by trapped air. Temperatures are more easily controlled as heat does not readily escape or enter. Our wall cladding, together with the completed wall rendering panel (built in accordance with the installation manual), meets the Bush Fire Attack Level (BAL) 29 which offers peace of mind to customers and allows you to buy with confidence.


Strong external cladding panels

The insulating core is reinforced with the fiberglass enhanced surface coating technology, providing strength and impact resistance against everyday backyard knocks.


ThermaWallPlus® has been developed and made in Australia by RMAX specifically for Australian conditions and building codes in all states. It is manufactured in RMAX plants under controlled production processes to maintain consistent quality. Australian made building products support the industry and help build a more vibrant economy that benefits all Australians.

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.
