Difference Between Ember Guard and Gutter Guard

Bushfires devastate the country and hurt millions of homeowners with thousands of Aussie businesses and homes destroyed. 70% of residents living in bushfire risk zones are unaware of the importance of ember guard against flammable debris. Educate your customers on the significance of ember guards vs gutter guards.

So, what is the difference between gutter guards & ember guards? The primary difference is the aperture size in the gutter mesh. An ember guard compliant mesh must have a hole size of 2mm or less, while there is no size requirement for gutter guards.

A gutter guard stops leaves and debris from blocking gutters, while an ember guard prevents ember attacks in bushfire-prone areas. Ember attacks occur when windborne embers ignite unprotected gutters and gaps in homes and buildings.

There are minor differences between the two gutter mesh types, including non-combustible material requirements and BAL ratings for bushfire-prone areas. Continue reading to understand better the difference between your gutter guard products: ember guard mesh & gutter guard mesh.

What is Ember Guard Protection?

According to Australian Standard AS3959-2009, ember guards must cover any opening or roof cavity to protect from burning embers. In bushfire prone areas, 85% of homes burn down through windborne embers and not via direct contact with the bushfire.

Ember guards protect from burning embers meeting Australian Standards. Corrosion-resistant ember guards are non-combustible gutter mesh covers for roof ventilation openings, fascia, valleys, ridges, and hips. You can also intrinsically ember-proof roof ventilators, vent pipes, vented roof lights, roof light glazing and eaves ventilation openings.

 

Ensuring that houses are adequately protected from a bushfire is the best solution to such fire hazards. Installing ember guards to meet Australian standards is the best protective solution to the problem.

Ember Guards & Bushfire Attack Levels

Like gutter guards protect homes for a range of solutions, different ember guards meet different bushfire ember attack levels from BAL 12.5 to FZ BAL rated. These BAL standards are specified for new homes as a bushfire proofing measure. 

 

The Australian Standard AS3959-2009 mandates a different gutter guard product for a different BAL rating. For example, gutter guards in BAL 12.5 rated areas must have seal gaps that are more than 3 mm, such as that in roof sheeting, but BAL-Flame Zone ember guard mesh must be 2mm, steel or copper and cover all roof and gutter cavities.

Choose the right ember guard for your BAL rating:

  • BAL-LOW indicates low risk from burning embers, radiant heat, or flames, and your gutter guard choice should suit your gutter protection needs and not be restricted by ember guard requirements.
  • BAL-12.5 indicates some risk of ember attack, burning debris or radiant heat up to 12.5KW/m2, and aluminium ember guards comply with BAL 12.5.
  • BAL-19 suggests a risk of ember attack, burning debris or radiant heat up to 19KW/m2 with aluminium or steel ember guard complies with BAL 29.
  • BAL-29 means a high risk of ember attack, burning debris or radiant heat up to 29KW/m2 and aluminium or steel ember guards comply with BAL 29.
  • BAL-40 signifies extreme risk of ember attack, burning embers or radiant heat up to 29KW/m2 and only complies with steel or bronze ember guard mesh.
  • BAL-FZ means a severe risk of ember attack, burning embers and radiant heat over 40 kW/m2 and only comply with steel or bronze ember guard mesh.

Other ember guard application

The smaller hole size is also useful for other gutter guard solutions. Aluminium ember guards protect against fine-leaf trees like pines, jacarandas, and she-oaks. The smaller mesh hole size encourages other leaves and debris to filter through only a minimal rainwater runoff

Why Solar Mesh is a MUST & NOT an Optional Extra

Installing solar mesh on rooftop solar panels have become a necessity in Australia as it forms a protective barrier to potential bushfire threats. The installation prevent rodents, birds, and leaves from getting under the solar panels. This makes the solar mesh an absolute necessity and not an optional extra.

Bushfires have been raging through various regions of Australia destroying lives, business, and property. They have devastated our environment and neighbourhood. Accumulated leaf litter is one such factor that trigger bushfires. In the summer months, the accumulated dry leaves transform into dry fuel which increase the chances of a fire hazard.

It is best to protect housing and commercial property from the accumulation of dry leaves or nesting materials from roosting birds, especially under the space below the solar panels, as these may act as kindling for embers in a bushfire. A simple solar mesh will do the trick!

Solar Panel Bird Proofing protects from Damages Caused by Animals and Birds Nesting Underneath

Small birds and rodents prefer to stay in the space beneath the panels. These spaces protect the rodents from the elements, especially as they are dry and comfortable. However, they create a lot of mess on your customers’ rooftops and produce a rotten smell. The longer they remain, the greater the damage caused to the solar panels. Bird spikes are often  not an effective deterrent and other bird deterrents have mixed results.

Solar mesh prevent this from happening by bird proofing the solar panels. These leave no space for birds to roost and animals to rest underneath. The small mesh holes protect the panels from animals, but leave sufficient space for free airflow under the panels.

Though rodents do not cause any direct damage to the solar array, they bite into the wiring and the electric components, causing a short circuit in the wiring, which may lead to a fire hazard. When birds nest under solar panels, bird droppings accumulate in these spaces, which may then generate various types of diseases such as salmonella.

Pigeons have become prolific nesters under solar panels especially in Sydney and NSW. Pigeon proofing  solar panels will help keep these infestations away with a humane bird control solution

Solar Mesh Stop Debris Such As Leaves Collecting Under the Panels Which Become a Bushfire Hazard

Flammable debris like dry leaves have larger chances of igniting. It is feared that the leaves that pile up under the solar panel may be a cause for a fire waiting to take place. If your customer lives in a rural region where there are more trees, this causes a lot of concern to the people living there. Eucalyptus leaves are said to have oil content are considered easily flammable.  Flammable debris like leaves usually gather under the solar panels. Over a period of time, they accumulate as dry piles of leaves trap heat, which may also trigger a fire. This also worsens the efficiency of the solar panels.

Solar Mesh Prevent Wet Debris Accumulating Under the Panel That May Speed Up Corrosion on Metal Roofs

Storm and wet weather conditions can make the leaves under the solar panels wet and take a longer time to dry. The wet leaves corrode the metal roofs on top of the house, and there are chances of electrical arcing or equipment failure. If there is a build-up of ice from hail in the space under the solar panel, it may bring in an expansion strength, which puts pressure on the roof and the system. You can protect your customer’s precious solar panels from such hazards and prevent their investment from destruction with solar mesh.

Solar Mesh Provide a Finished Look and Blend In with Roofs with 24 Mesh Colours to Choose From

You customer can choose from our 24 mesh colours to beautify their rooftops and to match to the colour of their house. A bird mesh brings down cleaning and maintenance costs too. With protective steel mesh, you can keep out pests and prevent the solar installation from accumulating debris.
