Crimsafe vs Invisi-Gard
Crimsafe and Invisi-Gard are both genuine, Australian Standard-tested security screens, so the honest answer is that neither one is universally 'better.'
AS Standards: AS5039 minimum impact rating is 100J; Crimsafe Regular is tested to 550J and Crimsafe Ultimate to 750J.
Specification comparison
| Aspect | Crimsafe | Invisi-Gard | Advantage |
|---|---|---|---|
| Mesh grade | 304 structural grade (Tensile Tuff) | 316 marine grade | Invisi-Gard, inherent corrosion resistance |
| Mesh thickness | 0.9mm | 0.8mm typical | Crimsafe, tensile strength |
| Corrosion approach | Multi-layer coating + clamp-point protection | Inherent 316 chloride resistance | Different approach |
| Fixing method | Screw-Clamp (patented) | Proprietary clamp | Both meet Australian Standards |
| Independent impact test | Up to 750J (Ultimate); UQ-tested | Not independently published | Crimsafe |
Coastal advice
For a heavily exposed beachfront property, the inherent 316 corrosion resistance in Invisi-Gard’s mesh is a genuine point in its favour on paper. In practice, Crimsafe’s multi-layer coating system, combined with the Saltwater Series gel Securelux applies to every clamp screw on security screens, is engineered specifically to close that gap.
Conclusion
Both Crimsafe and Invisi-Gard are legitimate, tested security screen brands well above the standard of a basic flyscreen. The right choice comes down to your specific priorities, corrosion resistance versus raw strength, finish, warranty terms, and, just as importantly, who is actually installing it.
