French doors are one of the most attractive features in a Brisbane home, but they can also be one of the most vulnerable. If you’re in St Lucia, Indooroopilly, Paddington, Enoggera, Everton Park, The Gap, McDowall or anywhere across Brisbane’s west, and your French doors open onto a patio, verandah or garden, adding a security screen is one of the smartest upgrades you can make. This guide covers everything you need to know about French door security screens — how they work, what to look for, and how to get the right fit for your home.
Key Takeaways
French doors are often an easy break-in point for opportunistic burglars, thanks to large glass panels, a central join that can be pried apart, and hardware that’s typically lighter than a single entry door. French door security screens dramatically strengthen this vulnerable area with impact-tested mesh and multi-point locks.
Quality screens — like Prowler Proof’s ForceField and Protec ranges — deliver security, insect protection, natural light and airflow without changing how your existing doors open.
Custom-made screens are essential for a perfect fit around the existing door frame, flush bolts and hardware. My Security Company offers a free measure and quote across Brisbane’s western suburbs.
Modern security mesh doors can mirror the style of timber or aluminium French doors while meeting Australian Standard AS5039. Look for products listed with the National Security Screen Association (NSSA) and tested to the standards Prowler Proof builds to.

Why French Doors Are a Target for Burglars
French doors are often targeted because they present obvious weak spots: large glass panels, a central join that can be levered apart, and hardware that’s frequently lighter than what you’d find on a single entry door. For an intruder, that combination makes them an attractive, easy break-in point — especially when they face a rear garden or side courtyard hidden from the street.
Typical vulnerabilities include:
- Exposed hinges on hinged doors that can be tampered with
- Flimsy flush bolts on the inactive leaf
- Lightweight door frames and simple latches that can be forced
Queensland Police’s own home security guidance advises homeowners to “consider fitting security screen doors, designed and installed to Australian Standards” as part of a layered approach to protecting a home. In leafy, established pockets of Brisbane’s west — where older French and timber doors are common and rear gardens often back onto laneways or neighbouring properties — that advice is particularly relevant.
A strong French door security screen creates a physical barrier that absorbs impact and prevents the quick forced entry most opportunistic burglars rely on. If they can’t get through the screen in seconds, they move on.
How French Door Security Screens Work
French door screens are essentially a pair of hinged security doors installed in front of — or behind — your existing French doors. They mirror the double-leaf arrangement: one active leaf with the main lock for daily use, and a second inactive leaf secured with internal top and bottom flush bolts until you need the wider opening.
Here’s what separates a genuine security screen from a basic flyscreen:
Mesh retention — High-tensile stainless steel mesh (used in Prowler Proof’s ForceField range) or perforated aluminium (Protec) is locked into a rigid aluminium or steel door frame using a proprietary clamping or channel system — not simply glued or stapled. This resists pull-tests and prevents the mesh being removed.
Locking — Quality French door security screens use a multi-point locking mechanism that engages the frame at top, centre and bottom, resisting jemmying and prying at multiple locations rather than relying on a single latch.
Swing clearance — Screens are designed so your existing doors still swing freely. A professional installer positions the screen to avoid handle clashes and interference with your current French doors.
Security Benefits: From Easy Break-In Point to Tested Barrier
Adding a security screen transforms vulnerable French doors into a layered entry system. Instead of glass and a lightweight latch standing between your house and an intruder, there’s now a tested physical barrier that has to be defeated first.
Compliant security screens are tested to Australian Standard AS5039, which includes:
- Dynamic impact test — five hits at either 100 joules (SL100) or 200 joules (SL200), simulating kicks and shoulder charges
- Jemmy test — resistance to prying with a lever or screwdriver
- Knife shear test — the mesh must resist sustained cutting without yielding a usable opening
Prowler Proof’s ForceField and Protec ranges are both tested to the higher SL200 rating, while Diamond meets SL100 — still fully compliant, and a solid option depending on your home and budget. Beyond the mesh, multi-point locks and internal flush bolts prevent an attacker from forcing the door leaf away from the frame, which is a common failure point in cheap double doors and screen doors. A visibly robust screen also does some of the work just by being seen — most burglars are looking for the easiest option, and a tested screen and solid locks are enough to send them looking elsewhere.
Everyday Comfort: Insect Protection, Light and Airflow
French door screens aren’t just about keeping intruders out. In Brisbane’s warm, humid climate, they dramatically improve everyday comfort.
Insect protection — Security mesh with fine apertures keeps out flies, midges and mosquitoes, so you can leave a door open on summer evenings without letting bugs in.
Natural light and airflow — Prowler Proof’s ForceField mesh has a 42.5% open area, and Protec around 40%, so quality security mesh still lets a genuine amount of light and breeze through rather than shutting a room in.
Reduced heat and glare — Because the mesh sits between you and direct sun, it takes some of the edge off afternoon glare and heat gain compared with an open glass door, without blocking the view of your garden.
Being able to leave your French doors open while the screen stays locked means real cross-ventilation on hot afternoons — a genuine benefit in pockets of Brisbane’s west like Enoggera, The Gap and McDowall where the afternoon sun can be relentless, and it takes some pressure off the air conditioner.
Custom-Made French Door Screens: Getting the Fit Right
French doors vary widely in size, material and configuration, so custom-made security screens are essential for both performance and appearance. A custom fit eliminates the gaps and weak points that could be exploited by intruders or let insects through.
Common variations include:
- Timber door frames vs aluminium frames
- Rebated vs non-rebated central joins
- In-swing vs out-swing hinged doors
- Different flush bolt positions and existing hardware layouts
Matt from My Security Company carries out a free measure on-site across St Lucia, Indooroopilly, Paddington, Enoggera, Everton Park, The Gap, McDowall and the surrounding western suburbs — checking door frame condition, sill levels and clearances before manufacturing. Screens are built to millimetre-precise measurements so there are no gaps at the sill or head that could compromise security or insect protection, and lock and handle positions are set to avoid clashing with your existing French door hardware.
Installation Details: Door Swing, Handle Clearance and Hardware
Even the best security screen will underperform if it’s poorly fitted, so correct installation matters as much as the product itself.
Key installation details:
- Inward-opening French doors – Screen mounted externally for airflow
- Outward-opening French doors- Screen mounted internally to protect the mesh
The common “handle clash” problem — where the screen door handle collides with your existing door handle — is solved using build-out frames or offset handle positions, so both doors can pass through a full swing without interference.
Hardware choices include heavy-duty hinges rated for the extra weight of security mesh, quality internal flush bolts on the inactive leaf, and low-profile handles for a clean look. Get this right and the screen should operate smoothly and lock properly from day one — not just look secure.
