KEY FEATURES

Corrosion Prevention of Invisi-Gard’s EGP

The construction of security requires stainless steel mesh to be attached to an aluminium frame, bringing two different metals together which can lead to corrosion.

To prevent this type of dissimilar metal corrosion, Invisi-Gard® have developed and patented a unique clamping system, called Extreme Grip Protection (EGP). This system cleverly captures the mesh within the frame using specially shaped co-extrusions of PVC. A PVC wedge is then used to apply uniform pressure around the frame which locks in the mesh.

The EGP system, used only by Invisi-Gard®, means the mesh is able to be locked into the frame without the uses of screws or mechanical fixing, and means the potentially harmful contact between the metals is avoided.

316 grade stainless steel offers superior corrosion resistance over 304 as it contains an additional substance, molybdenum, giving higher protection from corrosion, notably in marine environments.

In fact, 316 is regarded as the standard marine grade material for this very reason. In the case of window and door, required to be exposed to the elements over long periods of time, it makes sense that corrosion resistance is a fundamental consideration.

A final key factor which distinguishes Invisi-Gard® products from the market, is that only the highest quality mesh is sourced which is consistently quality controlled and accredited under international standards.

FAQs

What is Invisi-Gard?

Invisi-Gard is Australia’s premier stainless steel security screen brand, available through Accent Windows in Melbourne. It is made from 316 marine-grade stainless steel mesh and is designed to provide superior security without compromising the look or feel of your home. Unlike traditional security screens, Invisi-Gard does not use visible bars or heavy grilles. Instead, its fine stainless steel mesh maintains clear outward views while keeping intruders and insects out. Invisi-Gard is manufactured by Alspec and all products are backed by a 15-year warranty.
Invisi-Gard uses 316 marine-grade stainless steel mesh rather than the 304 grade steel found in most competing products. Grade 316 contains an additional element, molybdenum, which provides significantly higher corrosion resistance, particularly in coastal and marine environments. Invisi-Gard also uses a patented clamping system called Extreme Grip Protection, which according to Alspec, the manufacturer of Invisi-Gard, locks the mesh into the aluminium frame without screws or mechanical fixing. This eliminates the risk of corrosion caused by dissimilar metals coming into contact, a common issue with standard security screen products that use mechanical fixings.
Extreme Grip Protection, known as EGP, is Invisi-Gard’s patented method of securing the stainless steel mesh within the aluminium frame. Standard security screens attach mesh to aluminium using screws or mechanical fixings, which brings two different metals into contact and can cause corrosion over time. According to Alspec, the EGP system captures the mesh inside specially shaped co-extrusions of PVC and a PVC wedge is then applied to lock the mesh in place without any metal-to-metal contact. This approach makes Invisi-Gard significantly more durable and corrosion-resistant than standard mechanical-fixing security screen systems.
Yes. Invisi-Gard products are quality controlled and accredited under international standards. Invisi-Gard screens are designed to comply with AS 5039, the Australian standard for security screen doors and security window grilles, which covers requirements for strength, durability, corrosion resistance, and forced entry resistance. The mesh used in every Invisi-Gard screen is consistently quality tested to ensure it meets the performance requirements needed for a product exposed to the elements over long periods of time. For properties in designated bushfire-prone areas, selected Invisi-Gard systems can be specified up to BAL-40, subject to frame, mesh, hardware, and project requirements being assessed against AS 3959.
Invisi-Gard security screens can be fitted to a wide range of residential and commercial door and window types. Compatible applications include hinged doors, sliding doors, French doors, entry doors, sliding windows, awning windows, patio enclosures, and fixed screens. The aluminium frame of the Invisi-Gard screen offers a sleek, modern design that complements both the interior and exterior of your home without obstructing views or natural light.
Yes. Invisi-Gard is specifically engineered for environments where corrosion resistance is a priority, including coastal and marine locations. The 316 grade stainless steel mesh offers superior protection against salt air and moisture compared to 304 grade alternatives, which is why 316 is regarded as the standard marine grade material. For Melbourne homeowners in coastal suburbs or properties near Port Phillip Bay, Invisi-Gard is a well-suited security screen option given its marine-grade specification and patented corrosion prevention system.
Yes. One of the practical advantages of Invisi-Gard is that it can be retrofitted to most existing aluminium door and window frames without replacing the full door or window unit. Our team will assess your existing frames during the free measure and quote to confirm whether they are compatible with Invisi-Gard installation. In most cases, Invisi-Gard can be added to hinged doors, sliding doors, French doors, entry doors, and a range of window types including sliding, awning, and fixed configurations. This makes it a cost-effective way to improve the security of an existing home without a full door or window replacement.

The primary security function of an Invisi-Gard door comes from the 316 marine-grade stainless steel mesh and frame system, not the glass behind it. The glass in the door panel is specified separately to meet Grade A safety requirements under AS 1288. For standard applications, laminated safety glass is the baseline choice, holding the pane together with an interlayer if the glass is impacted rather than shattering. Toughened safety glass is an alternative depending on the door configuration, breaking into small blunt granules rather than sharp shards. For Invisi-Gard installations where thermal comfort is also a priority, a double glazed unit is available behind the screen and worth discussing with your Area Manager. Your glazing specification is confirmed based on your door type, orientation, and project requirements.
