Adding unique and formal features and concepts to the newly constructed house sounds appealing, but exclusive and complementing inventions also come with a high-security risk. Many homeowners prefer securing the regular doors, windows, and exit and entry points by installing a video camera or a digitalized sensory-based security-based alarm system directly linked with law enforcement agencies. Safeguarding regular entry points is the priority before moving to the house and considering overall home security. However, sliding doors are often neglected and overlooked in full-proof security, exposing the house’s back to would-be burglaries. This can ultimately be a massive breach of house security, allowing instant invasion resulting in a robbery or any other physical damage.

How to Secure Outside Track Sliding Glass Doors?

The best way to secure the outside track sliding glass door is to replace the latch with an actual lock. Next, you can drill self-tapping screws into the door’s upper track for additional protection. Finally, you can use a barricade (security bar) to make the door unopenable for additional security.

Please check the top 10 ideas on how to secure outdoor track sliding glass doors:

  1. Lock Replacement:
    • Most sliding doors come with a simple latch system which is not the most secure option.
    • Replace the latch with a robust, high-quality lock system.
  2. Install a Double Bolt Lock:
    • A double bolt lock provides added security because it requires the door to be locked at two points.
  3. Add Security Bars or Rods:
    • Place a metal or wooden bar along the track inside; it prevents the door from being opened from the outside, even if the lock is bypassed.
    • Ensure the bar or rod fits snugly into the track to work effectively.
  4. Install a Security Door Brace:
    • This device strengthens the door and makes it more difficult for intruders to force it open.
  5. Use an Alarm System:
    • Install an alarm system that triggers when the door is moved without deactivating the alarm.
    • Consider using a glass break sensor that triggers the alarm if the glass on the door is broken.
  6. Apply Security Film on Glass:
    • Apply a security film to the glass of the door.
    • The film makes the glass harder to break and slows down potential intruders.
  7. Install Security Cameras:
    • Having visible security cameras can deter potential intruders.
  8. Drill Self-Tapping Screws:
    • Insert self-tapping screws into the upper track of the sliding door.
    • The screws will prevent the door from being lifted off the track.
  9. Use Anti-Lift Devices:
    • These devices prevent the door from being lifted off its track from the outside.
  10. Consider using reinforced glass or Plexiglas:
  • Regular glass is easy to break, but reinforced glass or Plexiglas is a lot tougher, making it harder for an intruder to get through.

To increase sliding glass door security and protect the home from burglary, you can do the following:

Assessing Vulnerabilities

Before addressing security concerns, evaluating the vulnerabilities associated with sliding glass doors is essential. Typical weak points include:

  1. Flimsy Locks Many standard sliding glass doors come with basic latch mechanisms that can be easily bypassed or forced open.
  2. Fragile Glass panels can be shattered, enabling unauthorized access to your home.
  3. Accessibility Sliding glass doors often have large handles or locks visible from the outside, making them easy targets for burglars.

 Strengthening Sliding Glass Door Security

To enhance the security of your sliding glass doors, consider implementing the following measures:

  1. Install a Secondary Locking System Enhance the existing lock by installing a secondary locking mechanism, such as pin locks, Charley bars, or security bars. These additional locks provide an extra layer of security and prevent the door from being quickly forced open.
  2. Reinforce Glass Panels Consider reinforcing the glass panels to prevent break-ins. Options include applying security film, a transparent adhesive film that makes the glass more difficult to shatter, or using laminated glass, which consists of multiple layers with a plastic interlayer that increases its resistance to impact.
  3. Install a Security System Integrate a home security system with sensors specifically designed for sliding glass doors. This setup can deter intruders and alert you to unauthorized attempts to access your home.
  4. Implement Motion Sensor Lights Illuminate the exterior of your sliding glass doors with motion sensor lights. Well-lit areas can discourage potential burglars and make it more difficult for them to approach your home unnoticed.
  5. Use Window Treatments Consider using blinds, curtains, or frosted glass films to limit visibility into your home. This prevents potential intruders from scouting your property and reduces the temptation to break in.
