AS5203-2016 asks one blunt question: can the screen take 250 newtons of outward force without letting go. That is roughly a small child putting their whole weight against it. Alu-Gard and Alu-Gard Edge are both tested to it, which is exactly why a security screen belongs on an upstairs bedroom window and a flyscreen does not. If fall prevention is the reason you are buying, say so when you enquire and we will spec accordingly.
The same screen passes AS5041-2003: dynamic impact, jemmy and knife shear. It is fastened to the frame and stays there, and that is not a limitation, it is the mechanism. A screen you can pop out from outside is a screen an intruder can pop out from outside, which is precisely why the standard attacks the retention system with a knife. The same system also runs as balustrade and as fencing, so one specification can cover a whole project.
Perforated aluminium runs 40% open area, so daylight and airflow carry on much as before. Invisi-Gard mesh is finer again. From inside a room, standing back, the screen reads as a faint shadow across the glass rather than something bolted over the window. Standing right against it you will see it, and any supplier who tells you their screen is invisible from a foot away is overselling.

Three things drive it and none is a mystery: the size of the opening, which system you choose, and whether we are installing. Riveted Alu-Gard is the entry point. Alu-Gard Edge sits a little above it for the cleaner pressure-fitted finish. Invisi-Gard is the premium end. Send your openings and you will get a real number rather than a range.
Yes. A casement needs its winder to still operate with the screen fitted, which is a measuring question rather than a product limitation. Tell us it is a casement when you send the sizes and we will allow for the handle and the throw of the sash.
Fixed. They are fastened to the frame and stay there, and that is what lets them hold under AS5041 and AS5203 in the first place. If you need something that opens, you are looking at a hinged or sliding security door.
Not by hand, and deliberately so. Clean it in place with warm water, a soft brush and a mild detergent, then rinse well with fresh water. Avoid strong detergents and abrasive cleaners, they can scratch or damage the finish. If a screen ever does need removing, we can do it.
Not on that window. A fixed screen is fixed by design, which is exactly what lets it hold under AS5041 and AS5203, and that makes it the wrong product for an opening you may need to climb out of. Purpose-built emergency egress screens exist for this and release from inside. Flag any window your fire plan depends on when you send the sizes and we will spec that one differently.
Up to a point that depends on the system. Alu-Gard and Alu-Gard Edge meet bushfire requirements up to BAL-29 on the strength of the 2mm hole diameter. Invisi-Gard is rated from BAL-LOW through to BAL-40. Alu-Gard also carries a fire attenuation result the others do not: up to 56% at 40kW/m2 incident energy under AS1530.4-2014 Appendix B7. Check your BAL assessment before ordering, because above BAL-29 the aluminium systems are out.
That is exactly what AS5203 covers, and it is the reason to fit a security screen rather than a flyscreen on an upstairs window. Alu-Gard and Alu-Gard Edge are tested to resist 250N of outward force. A flyscreen offers no meaningful resistance at all and should never be relied on for fall prevention.
Yes. Trinity Beach, Kewarra Beach, Clifton Beach and Palm Cove are all in our regular run. Beachfront homes usually go stainless rather than aluminium, because the salt air is harder on hardware than most people expect.
