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 in ThermaWallPlus® is treated with Perform Guard®, an inorganic material that is a deterrent to termites. It provides fully integrated protection for the life of the ThermaWallPlus® used in a building's construction. It is not a surface additive.
How ThermaWallPlus® Insulates
Heat flow is restricted from passing through ThermaWallPlus® by trapped air. Temperatures are more easily controlled as heat does not readily escape or enter through ThermaWallPlus®.
The insulating core is reinforced with the ThermaWallPlus® fiberglass enhanced surface coating technology, providing strength and impact resistance against everyday backyard knocks.
ThermaWallPlus® is a quality Australian made product. It has been developed in Australia by RMAX specifically for Australian conditions and to meet the stringent Australian Building codes in all states. It is manufactured in RMAX plants in Australia in 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.
RMAX ThermaWallPlus® has been approved as an external cladding and wall insulation system and accredited by the Building Regulations Advisory Committee (BRAC) under the BRAC Certificate Number v11/10. Click to view.
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.
The results of the BAL 29 testing are summarised in the test certificate as shown below.
