If you’ve ever tried to enjoy a Queensland evening without choosing between airflow and security, you already understand the problem stacker doors are meant to solve. The issue isn’t the idea of a stacker door — it’s that most stacker doors come with standard flyscreen mesh that offers almost no protection against forced entry.
Crimsafe Stacker Doors change that equation entirely. They combine the wide, unobstructed opening of a stacker door with Crimsafe’s tested-and-certified stainless steel mesh — giving Queensland homeowners the airflow they want and the security their home needs.
What Is a Crimsafe Sliding Stacker Security Door?
A stacker door is a multi-panel sliding door system where each panel slides and stacks behind the other, creating a wide, clear opening — typically used on patios, alfresco areas, and indoor-outdoor living spaces.
Crimsafe Stacker Doors take the same frame and replace the standard screen with Crimsafe’s 304-grade stainless steel mesh, tensioned and locked into the frame using Crimsafe’s patented Screw-Clamp™ system. The result is a screen that cannot be pushed, pulled, or cut out of the frame — the most common method used in home break-ins.
The Independant Crimsafe v Other Security Screen Tests
Independent testing conducted through the University of Queensland and the Australian Defence Force Academy put a range of leading screen brands through the AS 5039 impact test and then kept increasing the force beyond the standard’s minimum requirement. The results were confronting: several well-known competitor products couldn’t even reliably survive the standard’s baseline requirement of five impacts at 100 joules — let alone anything harder.
This is the gap most homeowners never see, because it isn’t something a supplier volunteers on their website or in a showroom. A screen can technically be marketed as a “security screen” while barely — or not even — clearing the minimum legal bar.
The most telling part of that same independent testing round: even Crimsafe’s entry-level frame outperformed every competitor’s best-performing product by a wide margin. Crimsafe Regular — our standard, base-range frame — withstood a single impact of 500 joules. The strongest competing screen tested didn’t get close to that figure, meaning our regular frame is roughly twice as strong as the best-performing competitor screen on the market, not just an average one. That’s before you even step up to Crimsafe Ultimate.
Why Queensland Homes Suit Stacker Doors (And Why Security Can't Be an Afterthought)
South East Queensland’s climate is built for indoor-outdoor living. Homes in Brisbane, the Gold Coast, Sunshine Coast, and surrounding suburbs increasingly feature large alfresco areas, covered patios, and open-plan living that flows outside. Stacker doors are the natural fit.
But that openness comes with a trade-off if the screen isn’t up to the job. Queensland Police Service data consistently shows that unlocked or poorly secured doors and windows are the most common point of entry in residential break-ins. A wide stacker opening with a standard flyscreen is an easy target.
Crimsafe Stacker Doors let you open your home up without opening yourself up to risk.
What Makes Crimsafe Stacker Doors Different from Other Security Screens?
Not all security screens are built the same. Here’s what sets Crimsafe apart:
• Screw-Clamp™ system: The mesh is physically screwed into the frame — it cannot be kicked, punched, or cut away from the frame like mesh that is glued or crimped.
• 304-grade stainless steel mesh: Corrosion-resistant, suited to Queensland’s coastal and humid conditions.
• Tested to Australian standards: AS 5039 (security screen doors) and AS 5040 (security screen windows), plus impact, knife shear, and jemmy tests.
• Clear sightlines: The fine mesh maintains your view and airflow — it doesn’t feel like a barrier.
Alcom Security: Manufacturing Crimsafe In-House Since 1996
Alcom Security has been installing Crimsafe since its Australian inception in 1996. We manufacture Crimsafe frames in-house at our Loganholme facility — meaning we don’t outsource fabrication. Every frame is built, quality-checked, and fitted by our own team.
That matters for stacker doors specifically. Stacker systems need precise frame alignment to slide and seal properly. When the same team fabricates and installs, the tolerances are tighter and the fit is better. We’ve been doing it long enough to know every variable.
We service South East Queensland from our showrooms in Loganholme (South Brisbane) and Maroochydore (Sunshine Coast), covering Brisbane, Gold Coast, Ipswich, Toowoomba, and the Fraser Coast.
Pricing varies depending on the number of panels, size, and finish, the type of frame and how we are going to do the job. Contact Alcom for a free measure and quote specific to your home.
In many cases, yes. Our team will assess your existing frame during the quoting process. Where the existing frame isn’t suitable, we supply and install the full Crimsafe system.
Crimsafe products come with a 10–15 year warranty depending on the product range, and are designed to withstand Queensland’s coastal and subtropical conditions.
