Guardian’s safety origins are based on the need to have a fully operable window, at height, which helps eliminate the possibility of people (especially children) falling out.


We believe kids, and all family members, should be safe in their home. Guardian window screens have been designed to meet the requirements specified in the National Construction Code for fall prevention. Like all Prowler Proof screens, Guardian is welded with no visible joints in the corners. With its fine 304 stainless steel architectural mesh, views are seemingly unrestricted. It delivers greater natural air-flow to help cool and freshen any room, and has been tested to exceed an outward force of 250NM (25kg) as required by the National Construction Code, meaning any existing window restrictions can be removed.



In May 2013, the National Construction Code (NCC) implemented the requirement for window barriers on openable windows in early childhood centres and bedrooms of residential buildings, such as houses, apartments, hotels – where the window is more than two metres above the surface beneath.

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


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.



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.


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.
