Why Burglar Proof Windows?

You might be saying to yourself, “If I already have a home security system, why do I need to burglar proof my windows?” This is a valid question because you have your base system, motion sensors and door/window sensors as well (which is a positive step towards burglar proofing your home), but there are some additional steps you can take to help bolster your security for intruders who aren’t trying to come through the door. If intruders can easily crack your windows or get in without a lot of effort, it’s worth looking into the different ways you can further secure your home. Here are several recommended solutions you can look into.

8 Ways to Burglar Proof Your Windows

Window Locks

While your windows may already have locks, additional aftermarket locks can enhance your window security. The best type of aftermarket window lock may depend on the type of window you have. Several types of locks that you can purchase are:

  • Pin locks - These are recommended for installing on your ground floor windows. They can prevent intruders from lifting your windows.
  • Keyed locks - These locks will require use of a key to get them open and to keep them closed. You’ll just have to be sure to keep up with the key for this type of lock.
  • Hinged wedge locks - If you want to prevent a double-hung window, one that can open from both the bottom and top, from being opened, use a hinged wedge lock. You can adjust this type of lock so you can open the window partially if you install it higher on the frame of the window.
  • Sash locks - Sash locks will allow a window to open and also hold it shut in place. These are typically used for double -hung windows.

Window Sensors

If you already own a home security system, then you probably already have door/window sensors. These devices are designed to detect whenever your window is opened, and for some security systems, an alert will be chimed to let you know whenever this has happened.

Tempered Glass

Tempered glass is four times stronger than annealed glass, and when used in windows, these are known as safety windows. This type of glass goes through repeated heating and cooling phases to enhance its strength. If broken, this type of glass will crumble rather than break into jagged pieces. Burglars will have a harder time trying to get into your home with this type of glass, and they don't want to make a disturbance.

Plexiglas or Polycarbonate Windows

If you’re willing to pay more, plexiglas is impact resistant and ten times stronger than regular glass. This type of glass is made out of acrylic, and while it is not real glass, this type would also discourage burglars. Additionally, polycarbonate windows are stronger than plexiglas and can deter burglars. It wouldn’t be necessary to use these types of glass for all of your windows, but you could definitely be strategic in placement to lower the expense.

Security Cameras

One popular solution is adding security cameras to your home. If you want to keep an eye on what’s happening on your property, purchase an outdoor security camera and look for those that have HD video as well as night vision. If you want to monitor the interior of your home as well, look for HD indoor surveillance cameras. A great feature to have with an indoor camera is 2-way talk which allows you to chime in through your camera from your smartphone.

Window Bars

Window bar treatments provide an additional layer of security because even if a burglar smashes the glass, they won’t easily be able to squeeze through the bars. While you might feel hesitant to add bars to your windows, you don’t have to opt for the common ones that you may normally see on stores. There are decorative treatments that can be customized to fit your home’s style.

Floodlights/Motion Lights

Because burglars don’t want to be caught in their tracks, floodlights or motion lights can help to deter them from breaking into your home. Some motion lights are designed with security cameras so you can see activity outside your home. You can also find motion lights that will send motion-activated alerts to your phone and can even sound an alarm to scare off intruders.

Thorny Shrubbery

As an older tactic, adding thorny shrubbery around the windows of your home can help to prevent burglars from getting in. If a burglar attempts to break in at night and does not recognize the shrubbery you have planted, they’ll be in for an unfortunate surprise. When placed strategically around your home, plants can work for your security.

It’s especially important to keep children in mind and their safety. You can add thorny shrubbery in front of their windows, and for babies, you can even purchase a baby monitor that will allow you to check on your little one when you are not with them.
