Guardian Fall Prevention Window Screens

Open up second storey windows without the risk of falls.

Guardian Product Sheet

Guardian window screens have been designed to meet the requirements specified in the National Construction Code for fall prevention. They have been tested to exceed an outward force of 250NM (25kg), and are perfect for second storey window applications, to prevent falls, especially by young children.

guardian screen mesh

The aluminium frame and 304 architectural, stainless steel mesh are joined together in a mechanical and chemical bond. It is virtually unbreakable and provides complete insulation of the two metals...eliminating a major cause of corrosion.

Window Screens

The seamless corners make Prowler Proof ForceField the strongest and best looking security window screen in Australia.

A closer look...

Take a look at Guardian's features. It's the quality of manufacture, and focus on the small details that make Guardian unique. If you're looking for superior quality and functionality, look no further than Guardian.

screen welded corners

Welded Corners

All Prowler Proof products feature fully welded frame corners. A weld can be stronger than parts joined by a screw or rivet. It looks better too. The weld means the screen looks like it's made in one piece. You will immediately notice the difference when you compare Prowler Proof with a product that is held together by screws or rivets.

304 stainless steel mesh

Stainless Steel Mesh

The black powder coated, 304 stainless steel provides excellent resistance to corrosion. The 1.3mm aperture and 44.8% open area means Guardian provides excellent visibility and airflow. While the 304 steel mesh is .6mm diameter wire, it is ultra high tensile giving the mesh its strength to ensure it passes the requirements of the National Construction Code for fall prevention.

qualicoat powdercoat

Qualicoat Accredited Powder Coating

Prowler Proof is one of only 10 powder coating applicators in Australia to be approved by Qualicoat International. Qualicoat is an international benchmark of quality. Qualicoat International audits Prowler Proof’s powder coating line twice a year, to allow us to retain our certification. The powder coating is a key element in the appearance of a security screen. The long term benefit of choosing a Qualicoat certified screen is superior corrosion protection – as evidenced in the fact that Prowler Proof is the only security screen to pass the acetic acid salt spray test and the only manufacturer to offer a 10 year replacement warranty.

maximum transparency

Maximum Transparency

Guardian's mesh design ensures maximum visibility through the screen. Your views of outside will not be impeded by your screen.

full perimeter bond

Full Perimeter Bond

An adhesive is used to join the mesh to the frame. The frame is designed with special grooves that ensure when the adhesive is set you get both a mechanical and chemical bond. The adhesive is also used in other extreme applications such as aerospace and motorsports, where reliable bond through all sorts of conditions is required. The use of adhesives eliminates the corrosion associated with dissimilar metals joining, such as the joining of steel with aluminum. The use of adhesive as bonding material does not produce any deformation in the materials, improving the aesthetics of the product.

10 year replacement warranty

Full Replacement Warranty

All Prowler Proof product is covered by our 10 year replacement warranty. It's Australia's only screen replacement warranty and means you will get a brand new product if something goes wrong with your screen.


All Prowler Proof Guardian products come in 50 standard colours and another 250 optional colours. There is no extra delivery time and only a small premium on optional colours.

Tested to perform

Guardian has passed the testing requirements of the National Construction Code for fall prevention.

There's also a range of other performance tests that Guardian has met.

bushfire test


Bushfire prone zones require 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 (AS 3959-2009).

corrosion test


Whenever two different metals interact there is a risk of corrosion. The tests (AS 2331.3.2 and AS 2331.3.1) to show corrosion-resistance are the acetic acid salt spray test and neutral salt spray test.

insect protection test

Insect Protection

The mosquito protection test tests a screens ability to keep mosquitoes out over an extended period of time.

fall prevention test

Fall Prevention

The National Construction Code (NCC) (BCA 2013) requires that window openings be either restricted or screened, in certain circumstances, to prevent children falling. Screens that resist an outward horizontal action of 250 N meet the code and mean that window restrictors, that prevent the window being open more than 125mm, can be removed.
