Burglars are getting smarter, and they go through a lot to get into a house. Therefore, security is an important concern for homeowners, particularly when living in a high-risk or target-rich environment.

Securing your windows is one way to protect yourself from theft, and it doesn’t require any extra effort. However, if you don’t want to do it the hard way, plenty of other options are available.

To prevent this, you should secure your windows by adopting some potential techniques. However, if you’re looking for a DIY solution and don’t have much time or money to spare, this guide will provide some excellent tips on securing your windows cost-effectively.

12 Ways to Secure Your Windows Without Bars

There are several options for securing your windows without needing bars, which can be easy to tamper with. Here are 12 ways to secure your windows without installing expensive bars.

Improve security with a window alarm

A window alarm is a safety device used to deter the forcible opening of windows. The contact alarms typically used on doors can also be used on windows. However, these devices can’t differentiate between forced entry and regular window usage.

Door and window sensors are simple devices that monitor the opening or closing of a door or window. When these sensors detect motions in your window, it signals to the alarm, and you hear the sound.

Smart devices are compatible with these alarms, and you can control them from anywhere. You will also find three different options in the advanced window alarms. They are disarmed, home and away. You can set any of the options and keep your home secure.

Door or window sensors need not be hard-wired into your home as they can also be battery operated. They will work great with any of our security systems. For example, if you’re going away on a trip, it would be a good idea to set up an window alert system, so you’ll know if someone has broken into your house.

Install a Good-Quality Window Lock

Burglars won’t be able to get through your window if you’ve securely locked it. If a burglar tries to pry open a window and breaks the glass, there’s a chance for them to cut themselves.

Securing your windows with deadbolts or a roll-down locking bar will deter burglars from entering through these kinds of openings. Many windows are designed to include locks, but if that lock isn’t secure enough, or if a burglar can smash it out of the way and unlock your window, that lock won’t serve many purposes.

To ensure you’ve gotten the upper hand on possible burglars (or just wayward kids), consider buying a second lock that will be more secure than any standard model.

Install Window Security Film

Installing an alarm and locking in your window doesn’t protect your window glass from breaking. Burglars often avoid breaking the glass since they may get cut by the sharp edge of the broken glass, but that doesn’t mean they don’t do it. So, you can add this particular option to enhance security.

Installing a security film is easy to protect your home from broken and smashed windows. Anyone with a few essential tools can install this inexpensive solution.

Security films prevent the glass from shattering very effectively, and they are basically invisible, so burglars have no idea about this security method. As a result, the film helps prevent break-ins and protects against becoming a victim of burglary.

Also, this type of security film for home windows acts as laminated glass in case of an impact or break-in attempt. Therefore, it would be best to consider adding security film on all the windows in your home because you never know when someone might try to break in.

Use Motion detector

It would be best to find a way that doesn’t involve bars on the window. One option is to install a motion detector at the window so that if there is movement outside of the window, the alarm will go off and help keep us safe.

There are many motion detectors on the market, so it’s important to find one that fits our specific needs. Some motion detectors have a wide range to detect movement from far away. Others have a more focused range, so they can only detect movement within a particular area.

Add Altering the Glass

Adding altered glass to your home windows is a great security measure, especially for those living in areas with high crime rates. Installing this on windows, giving them more strength and making it harder for someone to break into your home.

With the addition of this security method, you can rest assured that your windows are secure against burglary, vandalism, and weather damage.

Laminated Glass

Adding laminated glass to your home’s exterior can also help improve your security. Laminated glass comprises two plies of glass sandwiched with a vinyl interlayer.

This is why these glasses are stronger than the regular ones and harder to break. Installing laminated glasses on our windows can give you superior safety and keep your family safe.

In addition, by making it more difficult for outsiders to see into your home, you significantly increase your chances of preventing burglary or theft.

Install outdoor motion sensor lights

Motion sensor lights work by detecting movement and automatically turning on. This way, you can easily see if someone is inside your house without turning on the light every time they enter.

Plus, since motion sensor lights are activated by anything that moves, they’re great for keeping an eye on things in corners and other areas you may not be able to see from regular light.

Of course, this will save you money in the long run, but it’ll also give you peace of mind knowing that everything in your home is safe and monitored.

Add Security Cameras

Security cameras are a great way to watch and record what’s happening outside your home, whether to keep your windows secure without bars or keep an eye on what’s happening inside.

Just make sure you choose one that is effective and fits your needs. This will enable you to see what is happening outside your home and may even help you detect unwanted visitors before they get too close.

Install window reinforcement hardware

Window reinforcement hardware is a necessary part of your home security. When the window frame is weak, the lock sits unnecessarily high on the window and can be more easily picked or broken through.

Also, installing window reinforcement hardware provides you with a more secure environment. Whether you’re looking to secure your home or even a commercial property, it can help prevent break-ins and intruders.

Use security grilles

Security grilles come in different shapes and sizes. However, they all work the same way: they attach to the outside of the window frame and prevent the window from being opened from the inside or outside without being first unlocked.

This is especially useful if you have children who may not be able to understand how to operate the security system on their own.

Polycarbonate Safety Shields

Polycarbonate shields protect windows, doors, and other building features from damage caused by balls or debris flying off the road. They come in various sizes and styles and can be installed on existing windows or over existing doors during construction or as an aftermarket retrofit.
