The Best Window Security Bars (aka Burglar Bars)

We all want to feel safe in our own homes, and we also want to protect our stockpiled reserves and equipment.

Window security bars can increase your home security, providing a visual and physical deterrent to anyone who is even thinking about breaking into your home.

Constructed out of steel or iron, they can withstand extreme pressure, making it almost impossible for anyone to force their way in without drawing attention to themselves.

Statistics indicate that around 23% of burglars use a first-floor window to access a property and 30% gain access through an open or unlocked door or window. Installing window security bars or burglar bars can significantly reduce the risk of burglary almost as much as reinforcing your front door.

Window security bars protect your home against intruders and safeguard your home’s inhabitants. They reduce the risk of accidents by making it impossible for children to fall out of the window and for pets to use it as an escape route.

Finding the best window security bars and installing them correctly will give you peace of mind and reduce the risk of intrusion.

The Pros and Cons of Three Types of Window Security Bar

In this article, we’ll look at the three main types of window security bars – permanent, hinged, and removable – and compare their effectiveness and suitability.


Permanent burglar bars provide robust protection but are banned in some states because they can trap people inside the house as effectively as they keep intruders out.

This is a safety hazard, preventing the inhabitants from escaping a fire or similar emergency.

Permanent burglar bars offer a visual deterrent and a physical one, but that means they will also obstruct your view through the window to a certain degree.


Hinged window security guards are similar to permanent ones but can be easily opened in an emergency. Both these styles provide a visual and physical deterrent to potential intruders, prevent pets from escaping, and eliminate the risk of accidental falls.


Removable window security bars are the least conspicuous and the easiest to install. They won’t provide the visual deterrent of a permanent window guard, but they will enable you to lock your windows even when they’re partly open. On the downside, they won’t prevent accidental falls.

To make this resource as informative as possible, we tracked down the best of each different type of security bar. Our criteria included ease of installation, material, cost, and legal compliance.

What To Look For In Window Security Bars

Ease of Installation

Maybe you’re happy to invest the time and energy required to install a permanent window guard correctly. On the other hand, perhaps you lack the skills or tools necessary to complete such a complex project.

A poorly installed window guard is even more dangerous than having none.

Not only could an intruder potentially break open or remove a poorly installed window security bar, but it could prevent you from escaping in an emergency.

Opt for a simple removable model unless you’re confident you’ve got the skills to install permanent or hinged window security bars correctly.


Most burglar bars are made of either iron or steel, which are strong and durable.

The best window security bars we found were made of carbon steel tubing. The downside of these materials is that they are neither rust nor weather-resistant. Some manufacturers are now creating invisible window security bars of transparent polycarbonate.

These are relatively rare at present but offer a rust-resistant alternative to metal.


If you only want to secure a single basement window, you shouldn’t have to spend more than $30 to $50 on window security bars. However, if you want to increase the security of your entire home, you’ll be looking at a significant investment.


Burglar bars can trap you inside just as easily as they keep intruders out, and that potential risk has led to some states introducing specific laws about what type of window security bar can be installed and where. These restrictions are known as the laws of egress.

For instance, permanent window guards are not permitted in California and Texas. The only type of window security bar allowed is one with an emergency release mechanism.

Rental agreements may also prohibit the installation of permanent security bars, limiting the options available.


Window security bars prevent intruders from accessing your home through a ground-floor window. Even if they break the glass, they will prevent them from entering.

Simple removable bars prevent the window from being forced open, while a hinged window guard will prevent anyone from removing or breaking the glass and gaining access that way.

Once you’ve chosen and installed your window security bars, you’ll want to ensure the rest of your home is equally well protected.

Whether you find out how to secure your door from being kicked in or commit to complete home security by applying these handy tips, your home and whatever you’ve stockpiled inside will be much safer than before you started.
