How to Secure a Sliding Glass Door – Our Invaluable Tips

How to Secure a Sliding Glass Door

Sliding glass doors are commonplace in Perth homes, allowing homeowners to create a seamless and effortless connection between the inside and back yard of their property. They offer convenience, visibility and some level of security; however, they can act as a potential entry point for intruders.

Sliding Glass Doors


So, how do intruders break into homes via a sliding glass door? Here are the most common ways –

  1. Bypassing the lock by “jiggling” or forcing the door until the basic latch lock breaks.
  2. Lifting the sliding door panel out of the track, as they are not hinged like regular doors.
  3. Smashing the glass panel with a heavy object like a brick or tool.
  4. Exploiting inadequate locks or outdated hardware on the sliding door.


To prevent the most common entry methods of sliding glass doors, some effective security measures include:

  • Installing a secondary lock like a deadbolt or sliding door lock at the top where the panels meet. These are much stronger than basic latches.
  • Use a security bar or “Charlie bar” that blocks the door from being opened even if the lock is bypassed.
  • Drilling a hole and inserting a lock pin/dowel through both door frames to prevent lifting the door off the track.
  • Applying shatterproof security film to the glass to prevent easy shattering.
  • Installing glass break sensors or a monitored alarm system as an additional deterrent.
  • Keeping curtains/blinds closed to obscure the view inside when not home.

However, if you’re looking for the most effective way to secure a sliding glass door, you’ll want to install an industry-leading security screen that meets or exceeds Australian Standards.

Secure Sliding Doors


There are several advantages to installing a security screen on sliding glass doors compared to DIY or other methods.


First and foremost, security screens and doors are a significant deterrent to would-be intruders and burglars. Unlike secondary locks, security bars, and alarm systems, security doors and screens are blatantly visible, and statistics show that homes with security doors and screens are less likely to be broken into.

Higher Level of Security

A robust and durable security screen adds a reinforced security barrier between your sliding doors and the outside. By selecting a security screen that meets or exceeds all relevant Australian Standards, you can rest assured that the lock, mesh and frame can withstand significant force.

Choosing a screen with an industry-leading warranty and maintaining it correctly ensures that your sliding door security screens stand the test of time.

These days, screens are available in 100’s of different finishes, styles, and materials, so you can custom-build a screen to your requirements.
