General Non Combustibility

The Australian Standard AS 3959-2009 Construction of buildings in bushfire-prone areas requires certain performances of building materials for various determined levels of Bushfire Attack Level (BAL).

This standard currently comprises six categories, namely BAL-LOW, BAL-12.5, BAL-19, BAL-29, BAL-40 and BAL-FZ.

For categories BAL-12.5 to BAL-40 all of UBIQ’s INEX>BOARDS meet the requirements for construction of buildings in bushfire-prone areas for external walls and protection of floor structures in so much as all INEX>BOARDS are deemed non-combustible by the standard*.

This includes; INEX>FLOOR, INEX>DECKING, INEX>MAXIDECK, INEX>RENDERBOARD, INEX>WEATHERBOARD and INEX>WALLBOARD.

There is no such requirement for BAL-LOW.

MAG003-General-Non-CombustibilityThis downloadable report prepared by Exova Warringtonfire on behalf of UBIQ confirms that INEX>BOARDS have been tested for Combustibility under Australian Standard AS/NZS 1530.1:1994 Part 1: Combustibility test for materials and that;
INEX>BOARDS are deemed Non-combustible.
This is the standard of non-combustibility that is required by the Australian Standard AS 3959-2009 Construction of buildings in bushfire-prone areas – clause 1.5.19 Non-Combustible.

Building Specifiers are free to download this report for submission to Building Certifiers if/as necessary.

* It is noted that there is a requirement for a minimum thickness of approved non-combustible external wall materials depending on the BAL-Level, which is as follows:-

BAL-12.5 to BAL-29: Minimum 6mm thick
BAL-40: Minimum 9mm thick
