Security Screens
A guide to the home’s openings

Screens, doors and safe windows

What the security screen standard covers, how to get out past a locked screen in a fire, the rules for windows and children, locks in a rental, and mesh for bushfire country.

A plain-language guide published by Dotto, written from the official sources linked on each page: Standards Australia, the fire services and the state tenancy and strata bodies.

Drawing, not to scale. A screen is a frame holding an infill; the weave is what you see when you look closely.
Six guides

Six panels, one frame

Each guide answers one question about the screens, doors and windows of a home, written only from the official page it links.

The standard

The standard, as its own listing describes it

Standards Australia lists the security screen standard as AS 5039, in three parts. Its listing describes Part 1 as the performance requirements for every kind of security door and window screen, whether hinged, sliding, folding, removable or fixed, used in buildings of Class 1 to Class 10, and “concerned primarily with resistance to forced entry”.

From Standards Australia’s store listings, read 8 October 2026. All three parts are listed as current.

Keys and escape

A screen that keeps people out must still let you out

Fire Rescue Victoria

Whenever you are inside, leave the key in any door or security screen you have locked.

Tasmania Fire Service

Recommends that windows and locks be easy to open from the inside, and says the best option is deadlocks that open from the inside without keys.

NSW strata rules

A different job: stopping a fall. Security screens can be used instead of window safety locks in a strata scheme, but any gaps must be less than 12.5 cm.

What the fire services say about getting out · Windows and children

Two meshes

Not every screen is asked to do the same job

Against insects

Healthdirect’s advice is to use insect screens to stop mosquitoes getting inside, and to make sure they have no tears or holes.

Against embers

The CFA (Country Fire Authority) in Victoria says fly screens on doors should have a metal frame and a corrosion-resistant bronze or steel mesh with a maximum aperture of 2 mm.

And in a Queensland rental, a security screen or grille does not replace the working lock or latch the minimum housing standards ask for. The two kinds of screen, side by side.
