Testing & performance
Security isn’t a claim. It has to be proven.
A genuine security screen must do more than look strong.
PROWLER PROOF PERFORMANCE TESTING
Australian Standard AS 5039 covers how residential security screens are classified, installed and tested against forced-entry methods. Prowler Proof security products undergo independent testing to demonstrate the performance required for their security classification, with selected ranges tested beyond the minimum security requirements for other conditions and applications.The current Australian Standard is divided into three connected parts. AS 5039.1 covers classification and performance. AS 5039.2 covers installation. AS 5039.3 defines the methods used to test a screen’s resistance to attack.
To achieve security classification, the same test sample must withstand a series of demanding assessments designed to simulate forced entry. These include dynamic impact, jemmy, pull, probe, knife-shear and corrosion testing.
Prowler Proof ForceField and Protec have achieved Security Level 200 (SL200) in dynamic-impact testing, while Diamond has achieved Security Level 100 (SL100). Both levels represent compliant security classifications when the complete manufacturing and installation requirements are satisfied.
AS 5039.1
CLASSIFICATION & PERFORMANCE
Defines the performance requirements a residential security screen must satisfy to be classified as a security product.
AS 5039.2
INSTALLATION
Sets the requirements for how the security screen must be installed so that the completed installation performs as intended.
AS 5039.3
METHODS OF TEST
Defines the physical testing used to assess resistance to forced entry, including impact, levering, pulling, probing, cutting and corrosion.

DYNAMIC IMPACT
The Dynamic Impact test measures how well a security screen withstands a forceful impact. Products are struck five times at either 100 or 200 joules and must remain securely within the frame. ForceField and Protec have achieved SL200, while Diamond has achieved SL100.

JEMMY TEST
The Jemmy test simulates an intruder attempting to lever a security screen open. A 300 mm screwdriver is used at locking and hinge points, with up to 1.5 kN of force applied for 20 seconds to test the strength of the complete screen assembly.

PULL TEST
The Pull test simulates an intruder attempting to pull or wrench the screen away from its frame. Up to 2 kN of force is applied for 20 seconds at selected points to test how securely the screen and its infill remain held in place.

PROBE TEST
The Probe test checks whether an opening in the security screen can be widened enough for an intruder to reach through and operate the lock. A force of 1.5 kN is applied to opposite sides of the opening to test its resistance.

KNIFE SHEAR TEST
The Knife Shear test simulates an attempt to cut through the security screen. A heavy-duty knife is dragged along a 250 mm line with up to 350 N of force, repeated three times using a new blade for each attempt.

CORROSION TEST
The Corrosion test checks how well the screen withstands harsh conditions over time. Products undergo 240 hours of accelerated weathering to assess corrosion resistance.

Chalmers Security Installations supplied and installed a Prowler Proof external screen to a spare bedroom sash-style window that had not been able to be opened due to its 3rd level location with nothing underneath. CSI also supplied and installed a Prowler Proof hinged screen to the twin window in that room that does have an accessible roof. The complication for the most recent screen was needing to align with a major building repaint when scaffolding would be available. Stephen and Jennifer were extremely accommodating and patient and had the screen ready and able to get Chris (installer) to fit within a small time gap. I should add this was a minor piece of work from their perspective and they were responsive and flexible to get the job done. The increase in air flow is very noticeable and I don't have to worry about birds and other wildlife visiting that way.Posted on Google![]()

Wow, I made an online enquiry and I had a quote within 2 days and it was installed today after accepting the quote last Tuesday. They have been a pleasure to deal with and their customer service has been faultless. I would definitely recommend them and will use them again.Posted on Google![]()

My recent experience having a kitchen window screen replaced with Prowler Proof by Chalmers Security Installations can not be faulted. The price was great, they were efficient courteous, responsive and kept me informed at every stage of the process, with a fast turn around (just over 1 week from placing the order to installation). Installation was quick and seamless, respect and care was taken of my home. They arrived on time and the window looks amazing. A BIG thank you to the Owner, admin team and installers. Its an 11 out of 10 from me. I highly recommend this Company and will use again in the future.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
