Crimsafe for Stacker Doors: What You Need to Know Before You Buy

Stacker doors are one of the most popular architectural features in new Sunshine Coast homes – and one of the most overlooked when it comes to security. Here’s what to consider before you commit.

There’s a reason stacker doors have become the go-to choice for new builds and renovations across the Sunshine Coast. When they’re open, the boundary between inside and outside all but disappears. A living room becomes an alfresco. A kitchen opens to a pool deck. A bedroom connects to a private garden. It’s the indoor-outdoor lifestyle this region is built around.

But stacker doors come with a security challenge that most homeowners don’t think about until after they’ve moved in.

Wide openings are harder to secure than standard doors. Multiple sliding panels create more potential weak points. And a door that’s designed to disappear when open needs a security solution that works precisely because it doesn’t disappear, one that holds firm when it needs to.

Crimsafe stacking screen doors can address this issue. As a licensed Crimsafe manufacturer on the Sunshine Coast, it’s one of the most common conversations we have with homeowners – often after they’ve already moved in and realised the gap.

What Makes Stacker Doors Different From a Security Perspective

A standard hinged or sliding door is a single panel with a single frame and a single set of lock points. Stacker doors are multi-panel systems, typically two, three or four panels – that slide and stack in front of each other to open up a wide span.

That multi-panel design creates specific vulnerabilities:

  • Each panel junction is a potential weak point
  • Wide openings are more exposed to forced entry attempts
  • The size of the opening means a standard security screen won’t span it
  • Without a purpose-built security screen, the door glass itself becomes the barrier – and glass is not a security measure

If you’re building or renovating with stacker doors and not factoring in a quality security screen from the start, you’re leaving a significant gap.

How Crimsafe Solves It

Crimsafe stacking door screens are engineered specifically for wide openings and high-traffic access points. They’re not a workaround or an adaptation of a single-door product – they’re a purpose-built solution.

Here’s what sets them apart:

Tensile-Tuff® Stainless Steel Mesh Every Crimsafe stacking door uses 0.9mm, 304 structural grade Tensile-Tuff® stainless steel mesh. This mesh is independently tested to exceed Australian Standards (AS5039) for impact, knife-shear and jemmy resistance. It’s the same mesh used across the entire Crimsafe range – no compromise for larger applications.

Screw-Clamp® Technology The mesh is secured to the aluminium frame using Crimsafe’s patented Screw-Clamp® system – not glued, not riveted, but mechanically locked with tamper-resistant screws at close intervals around the entire perimeter. This is the critical difference. When force is applied, the system absorbs and disperses the impact rather than giving way at the edges.

Interlocking Panel Design Where the panels meet, an interlocking frame edge creates a secure connection between each section. This eliminates the weak junction points that would otherwise exist in a multi-panel door system. The panels can be configured to lock in the centre or along the right or left door jambs – whatever suits your opening.

Custom Made-to-Measure Crimsafe stacking doors are fabricated to your exact opening dimensions. There are no standard sizes, no off-the-shelf compromises. Every screen is made to measure.

What Range Is Available?

Crimsafe stacking doors are available across the Regular, Classic and Ultimate ranges -each using the same Tensile-Tuff® mesh and Screw-Clamp® technology, with differences in frame strength and additional features.

  • Crimsafe Regular – proven everyday security, independently tested to exceed AS5039
  • Crimsafe Classic – enhanced frame strength for added confidence
  • Crimsafe Ultimate – up to 40% stronger than Regular, with a wider, stronger frame and CF6 carbon-fibre reinforced Screw-Clamp™ – the preferred choice for high-risk or high-priority openings

The right range for your stacker doors depends on the size of your opening, its location on the property, and your overall security priorities. This is exactly the conversation we have with every customer during a measure and quote.

All ranges are available in a wide choice of powder-coat colours, including Dulux and Interpon options, plus woodgrain and anodised finishes, so the screen integrates with your door frame and home aesthetic rather than competing with it.

What to Think About Before You Buy

If you’re in the planning, building or renovation stage, these are the questions worth asking before you commit to a stacker door installation:

1. How wide is the opening? The wider the span, the more panels you’ll need and the more important it is to have a purpose-built security solution that covers the full width, not just the primary panel.

2. Where does the door face? A stacker door that faces the street, a laneway, or a less visible side of the property is a higher security priority than one that opens directly to a secure, fenced backyard. The orientation affects which range and configuration makes the most sense.

3. Are you building or retrofitting? It’s easier and more cost-effective to plan your security screens at the build or renovation stage, when everything is accessible and measurements are readily available. Retrofitting is absolutely possible, but coordinating with your builder early means a cleaner result.

4. What’s your lifestyle use? If your stacker doors are open frequently, entertaining, daily indoor-outdoor flow, a poolside connection – your security screen needs to be durable enough to handle constant use. Crimsafe is built for exactly this kind of regular, high-traffic application.

5. Do you want the screen to disappear when open? Crimsafe stacking door screens are designed to stack with the door panels when open. When you push everything back, the screen panels stack with the door, keeping the opening clear. Security doesn’t mean visual compromise.

A Note on New Builds and Builder Quotes

One of the most common situations we see on the Sunshine Coast is homeowners who’ve completed a new build, moved in, and then realised their stacker doors don’t have any meaningful security screening.

Builder-supplied screens – where they’re included at all are often basic aluminium flyscreen products that meet minimum requirements but offer no real resistance to forced entry. They’re not Crimsafe. They don’t use stainless steel mesh. They won’t pass AS5039 testing.

If you’ve just moved into a new home with stacker doors, or you’re about to, it’s worth getting a quote before something happens rather than after.
