How To Protect Your House From An Ember Attack

Proofing Your Gutters In Bushfire
Across Australia, bushfires have become a grave threat. However, the surprising fact is that the bushfire is not a direct threat to your house.

More than 85% of houses that become victims of bushfires do not directly come in contact with the fire but the embers that are windborne. This ember attack can burn your house down to debris, as it can not only set fire to other fuel sources near you but also cause an internal house fire due to the infiltration of embers through gaps that are as small as 3mm.

To prevent this, you need to be prepared for protection against an ember attack.

An Ember Attack
Ember attack is caused when there is flameless combustion. The burning remains of a fire scatter around outside or inside the house which then causes a fire. This debris can set alight various external sources, such as leaves in the gutters, or it can cause fire internally.

This is the reason why the Australian Standard (AS3959–2009) in construction that deals with bushfires have incorporated measures to handle ember attacks as well.

An Ember Guard
Ember guards are perforated or mesh sheets with a hole size/aperture of not more than 2mm. These sheets should be made from materials that are non-combustible to further qualify as ember guards. Your BAL (Bushfire Attack Level) tells you the level of risk you are at and the materials you should use. Gutter Guard King’s 2mm aluminum gutter mesh is a good option for an ember guard compliant mesh.

Gutter Guards
The problem at hand is that even though ember guards can help protect your house against ember attacks, they don’t really discuss the threat of external fires as a result of an ember attack. This is why an alternative at hand is using gutter guard-compliant gutter mesh. This not only prevents issues such as leaves clogging in the gutters but also decreases the number of sources through which external fires can ignite.

You are recommended to use an ember guard which complies with gutter mesh because it protects your gutters from embers and decreases the risk of external fires. You should use a gutter mesh that is non-combustible. This will ensure that it is a good pick for areas with a higher risk of bushfires.

Defense For Bushfire-Prone Areas
Even though no requirement guarantees that your house will withstand an ember attack, the mentioned measures do prepare your house for such an instance. The Australian Standard is applicable for new houses in bushfire-prone areas, but can also be used for old houses in such areas.

Ember Guard And Australian Standards (AS3959-2009)
Following the tragic Victorian “Black Saturday” bushfires during 2009, the Australian Standard for the way buildings should be constructed had been upgraded, especially in areas that are prone to bushfires. These new rules were introduced in the AS3959-2009, which were designed to reduce the risk of your home possibly catching fire. The new standards highlight construction details for new homes and buildings in areas where there is a bushfire attack level of 12.5 or above. Even though these measures do not fully guarantee protection against bushfires, they are still effective enough to prevent major damages.

What Is An Ember Attack?

AS3959-2009 was introduced and specifically tailored to protect homes from ember attacks. These take place when bark fragments, burning twigs, and windborne debris travel towards the fire igniting your house as they begin burning the fuel and vegetation surrounding it, or get pulled inside. 85% of bushfires that cause major damages result from ember attacks. Hence, to further strengthen and prevent your house from risks of Ember attacks, Gutter Guard King’ ember mesh and compliance with AS3959-2009 is a suitable solution.

What Does An Ember Guard Do?

Ember guard serves as a covering that is installed either inside or on top of an opening in your house as a shield from the attacks by blocking the entry of burning embers. Ember guards are made from several different materials, such as metal mesh with an opening of 2mm. Gutter Guard King’s 2mm gutter mesh acts as a compliant of ember guard, thus can be used in prescribed locations surrounding your house, assisting you to meet the requirements of AS3959-2009.

How To Use Ember Guard Compliant Mesh?

An ember guard compliant mesh can be used in a variety of ways to match the criteria of AS3959-2009. For homes between BAL 12.5 to BAL 29, the ember guard compliant mesh is required to be manufactured from either aluminum, bronze, or steel that’s corrosion-resistant.
In accordance with Australian Standards, the construction of new buildings in bushfire areas does not mandate equipping gutter mesh or gutter guards on new houses. Although, if you plan on installing or have installed gutter mesh in a new house located in a bushfire area, AS3959-2009 specifies that it should be produced from non-combustible materials. Gutter Guard King suggests the installation of a 2mm aluminum gutter mesh if your house is situated in a bushfire zone. Considering the fact that it’s non-combustible and small-sized to block out any embers, it should majorly prevent flammable debris such as leaves from entering your home, aiding protection against ember attacks.

Protect Your Home

No operation can guarantee the complete safety and protection of your home from the danger of ember attacks, however, by making use of ember guards as well as following the criteria of AS3959-2009, you can maximize the chances of your home’s survival!
