Purpose-built mesh protection for roof cavities, wall cavities, eaves, gaps and hard-to-protect building voids
Modern building designs leave more small cavities, gaps and concealed entry points than many people realise. These areas can become an easy access point for birds, rodents, possums, insects, wind-blown debris and, in bushfire-prone areas, ember entry.
At Screen Tech, we supply cavity mesh solutions designed to create a strong physical barrier while still allowing ventilation, drainage and airflow where required.
We have spent more than 20 years working with gutter guard, ember guard and screening products, and we understand that the wrong material in the wrong place can lead to poor results. That is why we help builders, architects, installers and homeowners select mesh based on the site conditions, the cavity size, surrounding vegetation, pest risk, BAL requirements, roof and wall materials, and the finish required.
Assess your cavity, ember guard & fire risk needs.
Match the mesh to your building type, space and Colorbond® colour.

Cavities and small construction gaps are often overlooked during design and build. Once pests or debris get inside, the problem can become expensive, messy and difficult to access.

ScreenTech supplies gutter guard and ember guard solutions to local professional installers Australia-wide. We team up with the best gutter guard experts in the business.
A complete bushfire protection solution includes protecting your solar panels. Ember guard does not work for solar panels as the hole size is too small, preventing optimal light and airflow. Our SolarMesh promotes increased airflow while reducing leaf litter or nesting material build-up that can ignite your roof cavity.
Our gutter guards come in a complete array of Colorbond® colours to perfectly match the roof-to-gutter. Our powder-coated mesh and accessories colour match for durability and optimal roofing aesthetics for your property.
Commercial buildings benefit from the commercial gutter and ember guards, preventing leaves and debris accumulation with BAL-rating products. We provide gutter guard specialist advice for architects, roofers and government bodies. Get access to commercial-grade gutter guards and ember guards.

## Why cavity protection matters
Cavities and small construction gaps are often overlooked during design and build. Once pests or debris get inside, the problem can become expensive, messy and difficult to access.
Screen Tech Cavity Mesh can help protect against:
* Birds nesting in roof and wall voids
* Possums, rats and mice entering concealed spaces
* Wind-blown leaves, bark, litter and organic matter
* Ember entry points in bushfire-prone areas
* Ongoing maintenance and difficult clean-outs
* Damage caused by pests, nesting material and blocked drainage paths
Birds, possums, rats and mice commonly use gutters, roofs, verandas, valleys, downpipes and concealed building spaces as nesting locations. The only reliable way to stop them entering is to deny access with a physical barrier.

## Designed for builders, architects and installers
Cavity Mesh is especially useful for:
**New homes and estates**
Greenfield sites can create ideal nesting conditions for birds because natural nesting sites are disturbed and new rooflines, gutters, eaves and solar areas provide warm, protected shelter. Screen Tech’s research with installers found many bird proofing jobs were on homes under five years old.
**Commercial and municipal buildings**
Schools, healthcare, warehouses, retail, government, retirement living and industrial buildings often have more complex rooflines, larger cavities and higher long-term maintenance risks. Screen Tech products are already positioned for these building types across gutter guard and ember guard applications.
**Architectural builds**
We work closely with architects so screening products blend into the building rather than looking like an afterthought. Colour, finish, mesh strength, aperture size and fixing method all matter when the product is visible or part of a high-end build.
**Bushfire-prone areas**
Where cavities could become ember entry points, mesh selection needs to consider BAL requirements, aperture size and material suitability. Screen Tech supplies ember guard products suited to BAL-rated applications, including aluminium and steel options depending on the fire risk level.

## Where Cavity Mesh can be used
Cavity Mesh can be supplied for a wide range of building gaps and protection points, including:
* Roof cavity entry points
* Eave and fascia gaps
* Wall cavities and cladding junctions
* Parapet and box gutter openings
* Valley and roofline voids
* Solar panel bird proofing interfaces
* Ventilation and drainage gaps where airflow must remain
* Custom architectural openings
* Retrofitted pest-proofing details

The mesh hole size is the critical difference between an ember and a gutter guard. Many gutter guards are fire-resistant, but only gutter guards with an aperture size less than 2mm meet the ember guard compliancy.
It depends on your gutter protection needs. A gutter guard protects your gutter from heavy downpours but is not ember guard compliant. If you need a gutter guard in bushfire-prone areas, you must get an ember or gutter guard that complies with your BAL ratings. If you live in tropical climates or areas prone to steady heavy rain, we recommend a commercial-grade mesh for added durability and strength. Visit our TuffMesh page for more details.
Aluminium gutter guard is the metal of choice. Aluminium gutter guards are more robust and non-reactant. Steel gutter guards systems are powder-coated, but they will react and rust more quickly as the coating breaks down. The aluminium gutter guard’s extruding process offers more longevity and strength than steel welding. View our GutterMesh & TuffMesh aluminium ranges and steel mesh ranges.

Yes. Ember guards that comply with Australian standard AS3959-1999, such as our TuffMesh® range can be used with rainwater harvesting solutions. A rural home in a bushfire prone area with water tanks for drinking water must comply with Australian standard AS3959-1999.
Ember guard does not work with solar panels as the hole size is too small to allow optimal light and airflow. Our SolarMesh is a wire mesh that promotes increased airflow meaning your panels do not heat up and diminish the energy your panels can collect per day. It also protects your solar panels from collecting leaf litter and bird materials that ignite in a bushfire.
