Invisi-Gard by Verosol Dynamic Impact Test: AS5039-2008

We put our Invisi-Gard by Verosol range through tough conditions in independent testing facilities to ensure our products are tested to not just meet, but exceed Australian Standards.

This Australian Standard test simulates a kick to a security screen door.

This test was introduced after it was found that grilles fitted to security screen doors were subject to impact breakage through kicking of the grille panel.

The test is performed with a sand and lead filled bag and weighing around 40kg.

At impact the bag imparts 100 joules of energy to the panel being tested. The test is repeated 5 times, simulating repeated kicking as the burglar attempts to break into your home.

The test panel fails the test if the infill material (mesh) comes out of the door or window framing, or if the impact breaches the material in any way.

The Australian Standard AS5041 requires security screens and doors to resist five consecutive impacts, each of 100 Joules.

Invisi-Gard by Verosol easily meets this requirement and can resist in excess of 50 consecutive impacts, each of 100 Joules without failure.

Invisi-Gard by Verosol passes because of our Patented EGP Retention System which runs around four sides of the screen.

This Patented retention system resists the tendency of the mesh to be pulled out of the frame.
