INVISI-GARD Security Screens offer an unparalleled combination of security and clarity of vision. Constructed from aluminium and marine grade 316 stainless steel, they also use a unique, patented INVISI-GARD Pressure Retention and Isolation Method, which ensures the door’s mesh will defy even the most determined attack. Whether it’s from an intruder or corrosion!

INVISI-GARD Stainless Steel Security products don’t require screws or any other form of mechanical fixing to secure the mesh into the perimeter frame. As a result, the potential for corrosion through dissimilar metal contact is avoided.

  • 10x the strength of the Australian Standard in terms of absorbed energy
  • Heavy duty extruded aluminium perimeter frame for extra strength
  • The 316 marine grade stainless steel mesh can withstand  harsh environments such as coastal or industrial areas
  • Clean look with no unsightly screws or other fixings
  • All INVISI-GARD hinged doors are fitted with three-point locks and hinges for added security

Tested and approved in accordance with Australian Standards, INVISI-GARD delivers confidence in security across a wide range of products suitable for residential and commercial applications:

  • Hinged doors
  • Patio enclosures
  • Sliding doors
  • Emergency escape systems
  • Sliding windows
  • Pool fencing
  • Security screens
  1. Dynamic Impact Test: AS5039-2008This test is performed with a 40kg sand- and lead-filled bag. At impact the bag imparts 100 joules of energy to the panel being tested. The test is repeated 5 times, simulating the repeated kicks of a burglar attempting to break into your home. INVISI-GARD easily meets this requirement and can resist more than 50 consecutive impacts without failure.
  2. Lock and Hinge Lever Test: AS5039-2008
    This test simulates the effects of a jemmy attack against a security screen door or window grille. A standardised narrow-bladed lever (representing a large screw driver) is inserted against the locking, fastening and hinging points, and a turning force (torque) is applied. INVISI-GARD products pass this test, thanks to the quality of our hardware and the stiffness of our aluminium section framing.
  3. Knife Shear Test: AS5039-2008
    This Australian Standard test simulates a knife attack on INVISI-GARD as a burglar tries to cut through the screen with a Stanley knife or similar. INVISI-GARD is able to pass this test thanks to the strength of its 316 marine grade stainless steel mesh.
  4. Cyclone Rated: AS1170.2-2011
    One of the toughest tests of strength for a security system is the Cyclonic Missile Impact Test, in accordance with Australian Standards AS1170-1989. In this test a 4 kilogram piece of hardwood is aimed at the centre of the security screen and launched, reaching a speed of 15 metres per second (54 kilometres per hour) at the time of impact. Not only did the INVISI-GARD screen stop the timber missile in its tracks, but there was no breakage of the mesh and only a minor deformation in the centre of the panel!
  5. Bush Fire Testing to AS1530.8.1
    The INVISI-GARD system is known to be a robust fire attenuation screening solution, and has been proven even further with an Australian-first application of a Breezway Altair Louvre window system achieving a BAL40 level compliance.
