ARE YOU BUILDING IN A BUSHFIRE-PRONE

AREA IN NSW?

This guide provides a ready reckoner for acceptable timber products that can be used when building within bushfire-prone areas in New South Wales. Building for bushfire protection deemed to satisfy requires compliance with the following code, standard and guide:

Are you building in abushfire-prone area inNSW?

• The National Construction Code 2022 (NCC),

• Australian Standard 3959 – Construction ofBuildings in Areas•Planning For Bush Fire Protection, NSWRFS, 2019

When building in prone areas in New South Wales, there are additional requirements and limitations placed on construction. This ready reckoner is a quick visual guide to what can be built in timber and Flamefixx treated timber.

Building Types Requiring Bushfire Protection are summaries as;

• Single-family houses, duplexes or townhouses - Class 1

• Medium-density residential construction –apartments, hotels and motelsClass 2, 3 and 4

• Healthcare building; early childhood centre; andprimary or secondary school - Class 9 building

• Special fire protection purposes such as occupatedby mentally or physically incapacitated persons,seniors or retirement housing

• Sheds, garages or decks - Class 10a associated withany of the above

SPECIAL FIRE PROTECTION PURPOSES BUILDINGS

Healthcare buildings, early childhood centres,primary or secondary schools, buildings occupied by mentally or physically incapacitated persons, seniors, and retirement housing a respecial fire protection purposes buildings in NSW. There is no DTS solution for the exterior exposed timber for these building types. Where timber is preferred, a Performance Solution must be proposed. Performance Solutions are outside the scope of this guide.

BUILDING IN BAL AREAS

Building in BAL Areas up to BAL 29:

FLAMEfixx dFx Timber products are suitable for use with both enclosed and unenclosed decks for all BAL areas up to and including BAL 29. When building in these areas, it is crucial to adhere to AS3959 and we recommend installation in accordance with the Wood Solutions Domestic Timber Deck Design Guide.

Building in BAL 40 Areas:

For construction in BAL 40 areas, additional precautions must be taken due to the higher risk of bushfires. FLAMEfixx dFx Timber products used in BAL 40 areas are suitable for unenclosed applications.

Ember Protection:

FLAMEfixx dFx is compliant in all BAL areas up to and including BAL 40. However, if additional ember protection is required beyond what FLAMEfixx provides, supplementary protection measures,such as ember screens or additional fire-rated barriers, can be supplied and installed by others to further enhance the building’s resilience to bushfire attack.

TIMBER USED IN BUSHFIRE PRONE

AREAS

Many readily available timber products can be used within bushfire-prone areas without specific treatment or protection, including:

• There are no restrictions on the use of structural timber products for house framing that are not exposed to the outside.

• There is no limitation on the use of timber products for internal joinery,

• Some bushfire-resisting timbers can be used in external applications with out additional treatment.

• ITI’s Flamefixx can be used in all BAL levels up to and including BAL 40.

By selecting the appropriate materials and construction methodology, it is possible to build in timber while minimising the risk of ember attack, radiant heat, and even flame damage to your home during a bushfire.

WHAT IS A BRT? (BUSHFIRE RESISTING TIMBER)

AS3959 specifies timber used for construction in more bushfire-prone areas should not burn readily and that “timber may be ‘bushfire resisting’ by means of one or more of: the inherent properties of the material itself; or being impregnated with fire-retardant chemicals. The full lists of timber species is given in Appendix E of the Standard.

• Blackbutt

• Kwila (Merbau)

• Red Ironbark

• Red River Gum

• Spotted Gum

• Silvertop Ash

• Turpentine

• FLAMEfixx dFx®

BUSHFIRE ATTACK LEVELS NSW BAL RATINGS

As your home or building is subject to greater bushfire risk levels, the building will be subject to increasingly more stringent protection of the building envelope. To determine the risk level, the Bushfire Attack Level (BAL) must be assessed.

Check with your Local Council to determine the BAL of your property before planning your work. In NSW, the BAL is determined from the Planning For Bush Fire Protection, not the Australia Standard (AS 3959-2009) used in other parts of Australia. However, both methods are based on the same principles, considering the type of the surrounding vegetation,the distance of the vegetation from the site and the effective slope of the land under the classified vegetation.

The following provides a summary of the BAL as defined by the Planning For Bush Fire Protection:

Not Applicable (AS 3959 Classification BAL – LOW)

- Minimal attack from radiant heat and flame due to the distance of the building from the vegetation, although some attack by burning debris is possible. There is insufficient threat to warrant specific construction requirements.

BAL - 12.5

- Attack by burning debris is significant with radiant heat (not greater than 12.5 kW/m²). Radiant heat is unlikely to threaten building elements (such as unscreened glass). Specific construction requirements for ember protection and accumulation of debris are warranted.

BAL-19

- Attack by burning debris is significant, with radiant heat flux (not greater than 19 kW/m²) threatening some building elements (such as screened glass). Specific construction requirements for embers and radiant heat are warranted.

BAL - 29

- Attack by burning debris is significant, and radiant heat flux (not greater than 29 kW/m²) threatens building integrity. Specific construction requirements for ember and higher levels of radiant heat are warranted.Some flame contact is possible.

BAL 40

- Radiant heat flux and potential flame contact could threaten building integrity.

BAL - FZ

- Significant radiant heat and significantly higher likelihood of flame contact from the firefront will threaten building integrity and result in significant risk to residents.

If you are building a house in New South Wales, you can check your land’s BAL rating online.

The WoodSolutions Bushfire Calculator V2.1 is an online (to facilitate updating) design tool that enables building designers, builders, regulators, and homeowners to determine the relevant Bushfire Attack Level (BAL)for a specific building site.

NATURAL PRODUCT

FLAMEfixx dFx® is manufactured from timber, a natural product and it will react to climatic (moisture and temperature) changes during the life of the product.

FASTENERS

All fasteners and fixings used with FLAMEfixx dFx® are required to be Class 3 Galvanised, 304,or 316 stainless steel.

CLASS 3 GLVANISED

REGENERATIVE WOOD SPECIES

Radiata pine has a regenerative cycle of 28-30years – shortest in the world!

CARBON SEQUESTRATION WOOD SPECIES

Radiata Pine generates very high carbon credits (decarbonisation), 2-3 times that of indigenous species - 1 hectare of radiata pine trees will lock up 4-7 tonne of carbon per year. (or 15-26 tonne C02).

ENERGY EFFICIENCY WOOD SPECIES

Wood uses very little to produce compared to other building materials,

An externally rated corrosion method, Class 3 Galvanised fasteners can be used ingeneral outdoor applications.

• Externally rated

• Matte silver finish

Class 3 rated fasteners are not recommended for applications within 5km of breaking surf or in close proximity to swimming pools.

304 Stainless Steel is one of the most common materials used for fasteners.304 Stainless Steel:

• Protects the screw from corrosion in most external applications

• Has an attractive silver finish

• Is the material of choice for most decking professionals 304 Stainless Steel is not recommended for applications within 1km of breaking surf or in close proximity to swimming pools.

316 Stainless Steel is a marine grade of Stainless Steel. 316 Stainless Steel:

• Offers the greatest resistance from corrosion

• Can be used in severe environmental conditions

• Has an attractive silver finish

• Can be used in close proximity to salt water bodies like the ocean and swimming pools.

Coating FLAMEfixx dFx Products

FLAMEfixx chemistry is alkaline and consequently not compatible with every Wood Stain or Paint Coating. FLAMEfixx must be coated with penetrating oils like Cutek Extreme CD50 or Universal Timber Oil. Both penetrating oils offer a highly diverse aesthetic when used in conjunction with their array of colour tints.

304 STAINLESS STEEL
316 STAINLESS STEEL

PRODUCT IDENTIFICATION

Each FLAMEfixx dFx® product decking, screening and structural timber are edge-branded with the logo, BAL rating, treatment plant number & chemical identification number and Hazard Class [H3] all in a single,rectangular grid. And relevant Australian Standards.

Hot tip: For Joists and Bearers this should be facing down so it can be reviewed on site by a certifier or relevant authority.

INSTALLATION

FLAMEfixx dFx® Timber products are manufactured from Radiata Pine, a natural product that reacts to climatic changes during its life. While we attempt to minimise the effects, these changes may have on the appearance of the product, resin bleed, raised grain, surface checking, or uneven swelling may occur due to climatic conditions. To reduce the risk of adverse effects in the wood fibre, we recommend the following guidelines.

Installation Guidelines:

When cutting and handling FLAMEfixx dFx® products, it is recommended that all necessary PPE clothing including gloves, nose, eye and throat protection to prevent dust ingestion. Off cuts and sawdust are non hazardous and can be disposed of through standard waste collection and disposal facilities. Never burn FLAMEfixx dFx® offcuts.

SATEFY & DISPOSAL STORAGE

Store FLAMEfixx dFx® boards in a dry well ventilated area, and prevention measures should be used to minimise the impact of rising moisture from underneath the boards when stored.

STRUCTURAL PRODUCTS

Characteristic Strengths for FLAMEfixx dFx® structural products.

Follow standard preparation methods for installing treated timber and store it in a dry, well-ventilated location.

FLAMEfixx dFx® should be sized and installed in accordance with Australian Standards AS 1684 Residential Framed Construction Parts 2, 3or 4.

Ensure the boards are equal to the original size.

Any timber exposed through cutting or notching must be recoated with an approved preservative sealer (e.g., Protim Solignum XJ, Tanalised EnSeal,or Tanalised Ecoseal).

Apply a coat of penetrating oil (Cutek or Universal Timber Oil) to all cuts, notches, and holes before installation.

All fasteners should be Class 3 Galvanised or 304 or 316 Stainless Steel.

Remove all dirt, dust, or contaminants from the board surface or substrate.

Fill any defects, damage, or nail holes with compatible exterior filler. Once installed, apply a coat of penetrating oil to protect the product during construction.

Upon completion, apply one or two further coats of penetrating oil as per the manufacturer’s guidelines.
