INVISI-GARD is Australia’s premier security screen brand because it’s made from the toughest material in its class & features unique patented product architecture. The combination of these two vital features provides the maximum protection for your family & your home.

At the heart of every INVISI-GARD security screen & security door is the high tensile 316 marine grade stainless steel mesh. The grade 316 mesh used in INVISI-GARD sets the world standard in terms of its quality, precision & longevity.

This class leading mesh is retained in an aluminium frame using the patented EGP (External Grip Protection) retention system. This unique design ensures maximum strength & durability through an assembly technique that avoids contact between the two dissimilar metals – a major cause of corrosion over time.

INVISI-GARD is designed first & foremost to protect your family & home from would-be intruders and performs this task better than any other product on the market. It also protects your home from flying insects & maintains your view.

INVISI-GARD security doors & screens are without question the best investment for your family’s safety. They are also the best investment for the look & value of your home.
