Sliding Door Security – What are my Options?

Most Australian homes are fitted with sliding glass doors which typically create an accessway between a living room, dining room and/or laundry, to the backyard.

The addition of a sliding door security screen is the perfect option if you’re looking to add an extra level of security to your home. They are typically installed to the exterior brickwork, and provide many benefits in addition to bolstering your security –


Perth’s afternoon sea breeze can be a no-cost yet effective way to cool your home during the warmer months. A sliding door security screen allows you to keep your home secure while allowing air to flow through your home and, importantly, keep out pesky flies and insects. You may even be able to rely less on your air conditioning and reduce energy consumption/costs.

Privacy is not always a factor for side or back sliding doors, although it can be considered if you live in or around multi-story houses or apartments.

Visibility can be important, particularly if you have pets or small children who like to play in your backyard. Some screens are difficult to see out of, whereas others allow you to see out but not in, creating greater visibility, privacy and even security.

It’s important to note that different types of mesh provide varying levels of airflow, privacy and visibility, so try to select one that suits your individual requirements.

Security Sliding Doors


If you own a cat or dog, adding a pet door within your sliding door security screen will prevent you from constantly opening and closing your sliding door. This can also help to reduce the number of flies and insects that enter your home.

Modern pet doors are fitted with UV-stabilised plastic for added strength and visibility and a magnetic and lockable closure for greater security and insect prevention.

Please note that once a pet door is installed within a Security Door, it will no longer meet Australian Standards and can no longer be called a “Security Door”. Instead, it will be referred to as a Secure Door, Safety Door or Barrier Door. Furthermore, medium and large-sized pet doors may be large enough for a person to fit through and enter your home.

Sliding Door Security Screens


If you’re considering the addition of a sliding door security screen, there are many factors you’ll need to consider –

The Size of Opening / Style of Door

The size of the opening will dictate what style of doors are available. Smaller openings can only be fitted with single sliding doors, whereas larger openings can have single centre or even double slides to create a wider opening.

Another popular option is a stacking security screen which allows for larger openings.

Materials & Hardware

Most security screens have aluminium frames, however, the thickness/strength of the aluminium and system used to lock the frame to the mesh will vary considerably from one screen to another.

Invisi-Gard stainless steel doors are the only option on the market to incorporate the patented EGP retention method. This system locks the mesh into the heavy-duty extruded aluminium perimeter framing, which exceeds Australian Standard requirements.

For maximum strength, you’ll also want to select a screen with 316 marine grade stainless steel mesh – a high tensile woven mesh resulting in an exceptionally strong, corrosion-resistant product, powder coated in a very tightly controlled, chrome-free environment.

Last but not least, selecting a door with a 3-point locking system is essential. This is required by Australian Standards and creates substantially more security and strength than a single-locking system because it locks at 3 points on the jamb.

To simplify your selection process, you should select a sliding door security screen that, as a minimum, meets all Australian Standards.

Price & Installation

Sliding door security screens will vary in price considerably from one supplier to another. But paying more does not necessarily mean that you’re receiving a better quality and more convenient solution…
