Protec bay window


Protec screens are made from perforated aluminium, making them a great choice for coastal areas. They provide excellent security and visibility at a cheaper price point than stainless steel security mesh.


Protec screens are made from a single sheet of perforated aluminium, with welded, seamless corners, and powder coated in over 300 colours to the highest standards. The perforations are small enough to keep insects out, and big enough to allow excellent airflow and transparency. The mesh is joined to the heavy-duty aluminium frame in a process unique to Prowler Proof.  

Protec is one of the strongest security screens on the market, passing all six tests required by the Australian Standards with ease. The 1000 hour neutral and acetic acid salt spray tests for withstanding corrosion were not much of a challenge either. Protec also meets requirements for bushfire prone areas, up to Bushfire Attack Level BAL-29.

Why choose Protec

Made from a single sheet of perforated aluminium, Protect feels more rigid than a stainless steel screen. With a slightly lower open area and viewing angle, it is great for applications where you prefer a slightly restricted view, such as an entry door or bathroom window.

Protec more than passes all the Australian Standards for security screens. Made from a single sheet of perforated aluminium, it has proven high resistance to corrosion. It also meets the bushfire requirements to BAL-29. And they come with an 10 year full replacement warranty to give you complete peace of mind. 



Protec screens are available in fixed windows, hinged doors, sliding doors, stacking doors and fixed screens.

If you need to open your security screens, Protec is available in side opening hinged escape windows, opening either in or out. And they are the only security screen windows you can completely remove!



Protec screens have seamfree welded corners, joined by state of the art welding robots. There are no screws and rivets, so no chance for corrosion that can occur when two different metals interact. And most importantly, Protec screens feel like they're made in one piece - they feel stronger because they are stronger. 

All security doors come standard with Lockwood triple locks. All doors come standard with bug strips; and hinged doors with door closers.

Industrial strength adhesive bonds the stainless steel mesh to the frame. The adhesive is applied to a dove tail groove in the frame, and penetrates through the mesh, filling all the gaps and creating a complete mechanical bond between the mesh and the frame. The adhesive is so strong it's used in aerospace and motor sports applications. 

A sleek retaining strip hides the join and finishes the frame, leaving you with the best looking screen on the market. 

102 standard colours

Protec is available in 102 standard colours, and an additional 200 colours at extra cost. All screens are powder coated at the Prowler Proof Brisbane factory to the highest standards.

Locally made

Protec screens are made right here in South East Queensland, at the state of the art Banyo factory. Prowler Proof has achieved a 'World Class' rating on the PROBE Manufacturing global benchmark. PROBE is an international diagnostic assessment that benchmarks an organisation across a selection of international companies. Prowler Proof achieved ratings 20 and 19 points above the industry average, and well above the requirement of a World Class rating.

Product information

Security screens must meet standards for both construction and installation in order to qualify as security screens, as well as passing stringent tests. Australian Standard  AS5041 sets out the required tests for security screen doors and windows. Key tests include the dynamic impact, jemmy  and knife shear tests. In addition, there are safety standards for fire, cyclones and corrosion. 

Security test results

Dynamic impact test

The dynamic impact test simulates an intruder trying to kick through a security door or window. A bag full of lead shot and sand weighing more than 40 kg is smashed into the security screen with a force of 100 joules, repeated 5 times. Protec screens pass the test with ease, withstanding forces that no human could apply.

Jemmy test

The jemmy test is designed to simulate an intruder using a lever to get past the security door or window. The test is performed with a large screwdriver at all locking, hinging and fastening points. The force applied is up to 450 N (45 kg) for 20 seconds – way beyond the capability of most potential intruders.​ Even with substantial force applied, Protec locking and fixing points just won't give way.

Pull test

Imagine an intruder trying to pull out your security screen…that’s what the pull test is all about. The security door or window must be able to withstand pulling forces of up to 2 kN (200 kg) for 20 seconds at various positions from various angles. Nothing could pull out the Protec screen!

Probe test

The probe test simulates an intruder having created a gap and trying to get a hand inside to unlock a door or a window. A deflecting force of 1.5 kN (150 kg) is applied to each opposite side of the opening to increase the space enough to get a hand through. Protec passed, of course - it is not possible to get a hand inside the aluminium sheet. 

Shear test

The shear test simulates a cutting plier attack on a security screen. The shearing tool applies increasing pressure until the sample chord breaks. The force required to break one chord must be at least 3 kN (300 kg). It is not even possible for the pliers to get a hold on Protec screens. 

Knife shear test

The knife shear test simulates a knife attack on your security screen. A heavy duty trimming knife is dragged along a 250 mm line with a force of 150 N (15 kg) vertically and up to 350 N (35 kg) horizontally. The test is repeated 3 times, each time with a new blade, along the same line. The test leaves hardly a scratch on Protec screens. 

Endurance test results

Bushfire test

Protec screens are suitable for bushfire prone areas. With perforated aluminium mesh, Protec screens are approved up to Bushfire Attack Level 29 (BAL 29). The Australian Standard for construction of homes in bushfire prone zones (AS 3959) states that openable windows must be screened with corrosion-resistant steel, bronze or aluminium mesh with an opening of less than 2 mm x 2 mm. 

Salt spray test
AS 2331.3.1

Two factors make Prowler Proof resistance to corrosion - it is fully welded with no untreated or raw edges and it is powder coated after assembly, eliminating the risk of damage to the paint during assembly.


​The salt spray test tests the integrity of the screen in response to a spray that is saltier than sea water, in a closed chamber, at almost 100% humidity and 35 degrees. All Prowler Proof screens passed more than 1000 hours with no corrosion. 

Acetic acid salt spray test (AS 2331.3.2)

The 1,000 hour acetic acid salt spray test is pure torture. Acetic acid salt spray is saltier than sea water and 10,000 times more acidic. The test takes place in an enclosed chamber at a temperature of +35ºC with almost 100% humidity.

​Prowler Proof Protec passes the acetic acid salt spray test - the only brand to do so. If you live in a coastal area and are worried about corrosion, Prowler Proof is your safe choice. 

Energy and UV light

Protec mesh helps keep you warm in winter and cool in summer, by keeping out solar heat and UV light and reducing heat loss. In the Window Energy Rating Scheme (WERS) test, Protec reduced solar heat gain and UV light by up to 62% (WERS rating 4.5 stars). Reduced heat loss was up to 18%, resulting in a 2.5 star WERS rating.
