Most Australian homeowners invest in security screens for their front door, back door, and windows — and rightly so. But there’s a door that security professionals consistently flag as one of the most vulnerable points in the home: the internal door between your garage and your house. For many households, that door is hollow-core, poorly locked, and entirely without a security screen.
Installing a quality security screen door on your internal garage entry is one of the most effective — and most overlooked — home security upgrades you can make.
Why the Internal Garage Door Is a High-Risk Entry Point
A garage offers a burglar something your front door doesn’t: cover. Once inside your garage — whether through a compromised roller door, an unsecured side entry, or a remote-cloning device — an intruder is completely shielded from view. They can work on your internal house door at their leisure, using your own tools if needed, with no risk of being spotted from the street.
The Queensland Police Service makes this explicit in their Home Security Guide, stating that homeowners should “ensure that all external doors, including your internal garage door, are solid and fitted with quality locks.” Victoria Police similarly advises that the internal garage door must be locked at all times, alongside all other external entry points.
The pattern is consistent across Australian policing agencies: the internal garage-to-house door is not a secondary concern. It’s a primary entry point.
What makes this worse is that most internal garage doors are not built to the same standard as front or back doors. They’re often hollow-core, swing on standard hinges, and have basic lever handles — none of which offer meaningful resistance to forced entry. A security screen door rated to Australian Standard AS5039 changes that equation entirely.
What a Compliant Security Screen Door Actually Provides
A genuine security screen door is a tested and engineered product — not an upgraded flyscreen. Under Australian Standard AS5039, security doors must withstand impact tests, jemmy attacks, knife shear, and pull tests before they can be labelled and sold as compliant.
Prowler Proof security doors and screens are manufactured to meet and exceed AS5039, with our ForceField and Protec ranges achieving Security Level 200 (SL200) — the highest rating available, meaning they withstand five impacts of 200 joules. Every product features our signature toughened welded corners, a construction method unique to Prowler Proof in Australia, which eliminates the structural weak points common in screwed or snapped-together frames.
For a garage-to-house door, this level of protection matters. It means that even if an intruder has free run of your garage, the security screen door is the barrier that stops them from going further.
The Right Prowler Proof Door for Your Garage Entry
Not every garage-to-house door is the same — size, framing, ventilation needs, and budget all play a role. Prowler Proof offers three ranges suited to this application:
ForceField — Maximum Security, Maximum Visibility
ForceField uses genuine Meshtec 316-grade marine stainless steel mesh, rated SL200. The fine mesh is nearly invisible from inside, allowing a clear line of sight into the garage without compromising security. It’s the premium choice for homeowners who want the highest protection level and excellent ventilation — both valuable in a garage space that can heat up significantly in Australian summers.
Protec — High Security with Added Privacy
Protec uses a single sheet of perforated aluminium set into a welded frame, also rated SL200. The perforation pattern provides good outward visibility while limiting sightlines from the garage into your home — a practical consideration for an internal door. Protec is a robust, low-maintenance option that suits a wide range of home styles and is available in over 300 powder coat colours.
Diamond — Strong, Visible Deterrence
Our Diamond grille designs offer a traditional aluminium grille in Welded or SnapLock construction. A strong visual deterrent at a more accessible price point, Diamond suits laundry entries, rear access doors, and utility spaces — making it a practical choice for a secondary garage-to-house entry or a rental property upgrade.
All Prowler Proof ranges are backed by Australia’s only 10-year full replacement warranty — meaning if your door fails, you receive a brand new product, not a repair.
Installation Matters as Much as the Product
A security screen door is only as strong as its installation. Incorrect frame fixings, wrong-size fasteners, or poorly set hinges can allow a compliant product to fail under real-world force — defeating the purpose.
All Prowler Proof doors must be installed by a certified dealer who is a member of the National Security Screen Association (NSSA). NSSA members are trained and audited for compliance with Australian Standards, and your installation will be accompanied by a Manufacturing Compliance Label on the door itself — your proof that the product and installation both meet AS5039.
Frequently Asked Questions
In most cases, yes. Prowler Proof doors are custom-made to measure, and our certified dealers can work with existing frames in most home configurations. During your free measure and quote, your installer will assess the frame condition and recommend the best fixing approach.
ForceField and Protec both allow excellent airflow while the door is closed and locked. This is especially useful in a garage space, where ventilation matters for comfort and safety. You can leave the solid internal door open and rely on the security screen for both airflow and protection.
A screen door features a mesh or infill that allows airflow and visibility. A compliant security door provides a physical barrier proven by independent testing. For an internal garage-to-house door, a security screen door is typically the preferred choice — it lets you keep the solid door open for airflow, with the screen providing security.
Secure the Door Burglars Are Counting On You to Forget
The internal garage-to-house door is the entry point that gets overlooked — and experienced burglars know it. A Prowler Proof security screen door, properly installed to AS5039 by a certified dealer, closes that gap with tested, warranted protection.
