Amplimesh Vs Crimsafe Vs Invisi-Gard – What’s the Difference?

Amplimesh Vs Crimsafe Vs Invisi-Gard

If you’ve started exploring different security screen options, you’re probably wondering about the differences between Amplimesh vs Crimsafe vs Invisi-Gard.

Crimsafe security doors are the most well-known brand in Australia because of their strong advertising presence in recent years, particularly on TV. Although this does not necessarily mean they’re the best option when it comes to Amplimesh vs Crimsafe vs Invisi-Gard.

Here are some of the main differences between each manufacturer –


Both Invisi-Gard and Ampliesh use 316 marine-grade stainless steel. This is considered the best and most durable mesh on the market for Perth conditions and is highly recommended if your property is located within 5km of the ocean. It offers higher resistance to corrosion when compared to 304 Structural Grade High Tensile Mesh, which is used in Crimsafe security screens.

All 3 options of Amplimesh vs Invisi-Gard vs Crimsafe security screens and doors include aluminium frames. However, it’s important to note that stainless steel and aluminium do not work well together, particularly in coastal areas. So, a critical element to consider is how the aluminium frame holds the steel mesh.

Invisi-Gard and Amplimesh use a similar fully insulated method which reduces the contact between the steel and aluminium and prevents corrosion, which is great in coastal areas. The insulated pocket used in the Invisi-Gard is deeper than that used in Amplimesh, and the frame is heavier. This means that Invisi-Gard surpasses what is required by the Australian Standards for security.

Like any structure, a security screen is only as strong as its weakest component, and the locks are often a forgotten element when it comes to choosing between Amplimesh vs Invisi-Gard vs Crimsafe security doors. All 3 options come with triple locks, fixed-pin security hinges, screen door closers and subframes where needed.

Invisi-Gard doors come with either a Lockwood or Austral lock, whereas Crimsafe doors generally come with an Austral lock, and Amplimesh are fitted with Lockwood.


Invisi-Gard security doors are accompanied by a 15-year standard warranty on the frame and mesh, whereas Crimsafe doors have a 10-year warranty, which can be extended to 12 years. The Amplimesh SupaScreen® holds a 16-year warranty, and IntrudaGuard® holds a 10-year warranty.


Amplimesh is considered slightly cheaper when comparing Amplimesh vs Invisi-Gard vs Crimsafe security doors prices. However, this will depend on the style and type of door you select.

They were a great business to deal with, came when they said they would. We’re very up front on how long it would take to manufacture the door and windows.
