Invisi-Gard vs Crimsafe Security Doors: What’s the Difference?
When it comes to home and business security, choosing the right security door and screen can make all the difference. Two of the most commonly compared brands in Australia are Invisi-Gard and Crimsafe. Both offer strong protection, excellent visibility and airflow, and stylish design, but there are key differences that can influence which is right for your property.
In this post, we’ll break down Invisi-Gard vs Crimsafe — their construction, performance, aesthetics, warranties, and price — to help you make an informed choice.
What Is Invisi-Gard?
Invisi-Gard is a premium security screen system designed to provide:
– High-level intruder protection
– Excellent visibility and airflow
– Corrosion resistance for coastal areas
– A sleek, discreet look
Invisi-Gard achieves this with a tightly woven stainless steel mesh that’s tested to withstand forced entry while remaining nearly invisible from a distance.

What Is Crimsafe?
Crimsafe is a well-known security screen brand in Australia. It uses a patented “Screw-Clamp” system to lock a heavy-duty stainless steel mesh into the frame, ensuring the mesh stays in place even under force.
Crimsafe products are recognised for:
– Strong physical barrier performance
– Ability to be installed on doors, windows, and large openings
– Tested compliance with Australian standards

Invisi-Gard vs Crimsafe: Comparison Overview
| Feature | Invisi-Gard | Crimsafe |
|---|---|---|
| Mesh Type | Ultra-fine woven stainless steel | Heavy-duty stainless steel |
| Security Strength | Very high | Very high |
| Visibility | Excellent (almost invisible) | Good |
| Corrosion Resistance | Excellent for coastal environments | Good |
| Warranty | Typically strong | Wide range depending on installer |
| Appearance | Sleek, modern | Slightly more industrial look |
1. Mesh Type
The mesh is the heart of any security door or screen. It determines how secure the product is, how clearly you can see through it, how much air flows through, and how well it resists corrosion over time. That’s why mesh type should always be the first thing you compare when looking at Invisi-Gard vs Crimsafe.
Invisi-Gard Mesh
– Uses ultra-fine woven 316 marine-grade stainless steel
– Designed to be high-tensile, allowing slight flex under force rather than snapping
– Excellent corrosion resistance, especially in coastal or high-humidity areas
– Offers superior visibility — the mesh is almost invisible from a distance
– Provides strong airflow while maintaining security
Crimsafe Mesh
– Uses heavy-duty welded stainless steel mesh
– Each strand is welded at the intersections, creating a very rigid mesh panel
– Designed to work with Crimsafe’s patented Screw-Clamp fixing system
– Slightly thicker appearance compared to woven mesh
– Very strong, but less flexible under force
In essence, both mesh types are extremely secure, but they behave differently.
Invisi-Gard’s woven mesh prioritises visibility and corrosion resistance, while Crimsafe’s welded mesh focuses on rigid structural strength.
2. Security Performance & Testing
Both Invisi-Gard and Crimsafe are engineered to withstand forced entry and meet relevant Australian standards.
– Invisi-Gard relies on the strength and flexibility of its woven mesh combined with a secure framing system.
– Crimsafe relies on its rigid welded mesh and Screw-Clamp system to prevent the mesh from being pushed out of the frame.
In real-world terms, both provide excellent protection when professionally installed. The difference lies more in howthey resist attack rather than whether they do.
3. Visibility, Light & Airflow
One of the biggest reasons homeowners choose premium security screens is to maintain their view.
– Invisi-Gard offers exceptional clarity and allows more natural light through due to its fine woven mesh.
– Crimsafe provides good visibility but appears slightly more noticeable due to the thicker welded mesh.
If maintaining a clean, open look is important, this is where Invisi-Gard often stands out.
4. Corrosion Resistance & Coastal Performance
Australia’s climate — especially in coastal areas — can be harsh on security products.
– Invisi-Gard uses 316 marine-grade stainless steel, which is highly resistant to rust and corrosion.
– Crimsafe also uses stainless steel, but long-term performance can depend on model selection, coating, and environmental exposure.
For homes near the ocean or in high-humidity environments, mesh grade becomes critical, not just brand name.
5. Installation & System Design
Even the strongest mesh won’t perform properly without correct installation.
– Invisi-Gard systems are designed to be precision-fitted for a clean, modern finish.
– Crimsafe relies heavily on its patented Screw-Clamp system to mechanically secure the mesh into the frame.
Professional installation is essential for both — poor installation can compromise security, regardless of brand.
6. Price, Warranty & Overall Value
Both Invisi-Gard and Crimsafe sit in the premium security screen category.
– Invisi-Gard may be priced slightly higher due to mesh grade and corrosion resistance.
– Crimsafe pricing can vary depending on system type and installer.
Warranties differ by product and installer, so it’s always important to look at both the manufacturer warranty and the installer’s workmanship guarantee when comparing value.
Which Should You Choose?
Here’s a simple rule of thumb:
🔒 Choose Invisi-Gard if:
