When it comes to protecting your Perth home, you want a solution that doesn’t force you to choose between security and comfort. Our Invisi-gard security screen mesh doors deliver both. It keeps intruders out whilst letting the sea breeze in, blocks insects whilst maintaining your view, and stands up to Perth’s harsh coastal conditions without rusting or deteriorating.

What Is Security Mesh?

Security mesh isn’t just a tougher version of your standard flyscreen. This is because most security screens use woven stainless steel wire. Its tight weave creates a barrier that’s nearly impossible to cut, tear, or push through, yet still allows for ample airflow and visibility.

Compare this to aluminium grilles or bars, which block your view and make your home feel like a fortress. Security mesh gives you protection without the prison aesthetic. You can see out clearly, light flows in naturally, and the afternoon breeze still cools your home on those hot Perth days.

The mesh is typically stretched across a powder-coated aluminium frame and secured with special fixings that can’t be easily removed from the outside. The result is a screen that looks relatively unobtrusive but provides serious security.

Main Advantages of Security Door Mesh

Stronger Home Security

Your front and back doors are the most common entry points for break-ins. WA Police statistics show that over 13,317 residential burglaries occurred across Perth in 2025, with many involving forced entry through doors.

Security door mesh addresses this vulnerability head-on. When fitted to a hinged or sliding door, it creates a barrier that can withstand significant force. Most quality security doors include triple-lock mechanisms that engage at three points along the frame, making them extremely difficult to force open.

The mesh itself undergoes rigorous testing. If your security door meets the AS 5039 standard, you can be confident it’ll hold up against attempted break-ins.

Safely Allows Fresh Air & Light Into Home

Perth’s climate makes window security particularly important. We want to leave windows open for ventilation, especially during summer evenings when the Fremantle Doctor brings relief from the day’s heat. However, open windows are an invitation to intruders.

Security screen mesh solves this problem. You can leave your windows open day and night, allowing fresh air to circulate whilst keeping your home secure. The mesh blocks insects and flies, too, so you’re not choosing between ventilation and comfort.

For homes in bushfire-prone areas, security mesh offers an additional benefit. When properly tested and certified, security screens can meet BAL-40 ember attack requirements. This means they act as an ember guard during bushfire events whilst providing everyday security and insect protection. That’s three functions in one product.

At Perth Window and Door Replacement Company, we’ve seen growing demand for this dual-purpose solution, particularly after several incidents raised awareness about bushfire preparation.

Extreme Strength and Durability

The type of stainless steel used in security mesh makes a significant difference, especially in Perth’s coastal environment.

Invisi-gard’s 316 marine-grade stainless steel has become the preferred choice for quality security screens. It contains molybdenum, which provides superior resistance to salt corrosion. If you live within a few kilometres of the coast, this isn’t a nice-to-have feature. It’s essential for long-term durability.

The mesh itself is incredibly strong. The tight weave and wire thickness create a barrier that maintains its integrity for decades when properly maintained.

Powder coating the frame adds another layer of protection. The coating seals the aluminium against moisture and salt spray, preventing the white corrosion (oxidation) that often appears on untreated aluminium in coastal areas.

Meets Australian Standards

Not all security screens are created equal. The Australian Standards for security screens (AS 5039 series) set minimum performance requirements that separate genuine security products from glorified flyscreens.

The testing regime includes:

• Knife-shear test: The mesh must resist cutting with a Stanley knife or similar blade
• Dynamic impact test: The screen must withstand a 200-joule impact without failing
• Pull test: The mesh and frame must resist being pulled apart
• Jemmy test: The screen must resist being pried open with a crowbar or similar tool
• Probe test: Small tools shouldn’t be able to penetrate the mesh to reach the window latches

Products that meet these standards carry certification marks you can verify. When you’re comparing quotes, always check that the security screens comply with AS 5039. If a supplier can’t provide proof of compliance, walk away.

Installation standards matter too. AS 5041 covers proper installation methods to ensure the screen performs as tested. Poor installation can compromise even the best security mesh, which is why professional fitting is worth the investment.

Comparing Mesh Security to Traditional Flyscreens

If you’ve got standard flyscreens now, you might wonder if security mesh is worth the upgrade.

Traditional flyscreens use fibreglass, aluminium, or nylon mesh designed to keep insects out. They’re cheap, lightweight, and easy to damage. A sharp object, a determined pet, or even a clumsy moment with the vacuum cleaner can tear them. They provide zero security and minimal durability.

Security mesh, by contrast, is built to last. It resists tearing, cutting, and impact. Pets can’t damage it (even large dogs). The UV-stabilised stainless steel won’t degrade in Perth’s intense sunlight. And whilst it costs more upfront, you won’t be replacing it every few years like you might with flyscreens.

The intruder resistance is the obvious difference. A flyscreen presents no barrier to anyone wanting to enter your home. Security mesh does. It’s that simple.

Things to Consider Before Choosing a Security Screen Solution

Getting security screens right starts with accurate measurements. Security screens are custom-made to fit your specific door or window openings, measured in millimetres. Even small measurement errors can affect fit and performance, which is why professional measuring is worth it.

You’ll need to consider:

• Mesh grade: 316 marine-grade for coastal areas, 304 for inland locations (though we generally recommend 316 across Perth)
• Frame colour: Powder-coated black is standard, but most suppliers offer a range of colours to match your home
• Door style: Hinged, sliding, or bi-fold, depending on your space and preference
• Lock type: Triple-lock systems are standard for hinged doors; sliding doors use different locking mechanisms

Professional installation done by our team isn’t just about getting the screens to fit. It’s about ensuring they meet Australian Standards requirements and perform as intended. Incorrect installation can void warranties and compromise security, so it’s not the place to cut corners.
