How to Choose Interior Security Window Bars | Home DIY

Want to boost the security of your home windows? In this article we discuss tips for buying security bars, the difference between security window screens and window bars, and review the best interior security window bars.

We pay special attention to the windows when we build or rent residences. Among the factors we consider are the size, shape, location, trim and style. When making a decision, however, we seldom consider window security. If your window overlooks a busy road, your need for privacy will likely trump your safety concern.

However, when choosing between security and elegance, the latter is the better choice in most circumstances. Unwelcome guests like thieves (or wild animals) often use windows to enter. Who cares whether they’re human? Interior security window bars are excellent for keeping all these uninvited guests out.

Before you go to your local hardware store to buy the first thing you see, it is worth understanding the features to look for when buying window bars, and know the difference between window bars and security window screens to find out which is best for your needs. We’ll cover this, plus review some popular and well-rated security window bar products currently available.

Features to Look For When Buying Interior Window Security Bars

First and foremost, it is important for you to be clear on what your primary motivation for the window security bars is. There are two main reasons you might want to install window bars, with products specially designed for each purpose:

  1. Window bars for child safety
  2. Window bars for home security

Window bars for child safety

Window bars for child safety are designed to prevent children from accidentally falling from windows, especially if you live in an upper story apartment or have a multi-story house.

They are not designed to keep burglars out, instead they are intended to keep your children safe. Having said that, they may make it difficult for thieves to enter by obstructing their way, but if you are looking for window bars for home security purposes this is not the best product.

If you live on upper floors, then a window guard to prevent children falling from open windows is a must.

Window bars for home security

These window bars are designed specifically to enhance the security of your home, by preventing burglars from entering. You can get two different styles:

Full coverage window bars. These window bars cover the entire window. Brands include Grisham, Defender Security and Knape & Vogt. Even if someone breaks the window, they will not be able to get in. They prevent any access through the window, not only burglars, but also children, objects or large animals.

Single window bars. These feature one bar that prevents the window from sliding open. Brands include Wedgit and Jeacent. If someone smashes the window, they will still be able to enter. For basic security they are ok, preventing thieves from sliding open the window to get inside.

We have indicated in the reviews below whether they are single bar or full coverage, and whether they are designed for home security or child safety.

Essential Features – Window Security Bars Interior & Exterior

Here are some essential features to consider while looking for interior security window bars for your home.

  • Check the style, make sure it is what you want, either full coverage window bars or a single window bar. This depends on your personal requirements, but is worth mentioning so you don’t accidentally buy a product that is different from what you expected.
  • Choose security window bars that open from the inside for the best chance of keeping intruders out.
  • Ensure the security window bars enable users to escape the window in an emergency swiftly. In an emergency, like a fire, you need to make sure the window bars allow emergency escape.
  • It goes without saying that the window bars should be sturdy. Avoid any flimsy models that feel like they could be easily broken, cut or bent. Sturdy window bars ensure that intruders are unable to get indoors.
  • For exterior security window bars… check for tamper-proof screws. Security windows come with these screws, suitable for outside window bars. These screws make entering the house difficult.
  • For exterior security window bars… check for spears. The majority of them have spears around the perimeter for extra protection.

Window Security Bars vs Window Security Screens

Burglar bars and security screens are good choices for protecting your home’s windows. The first option resembles the bars of a jail cell, which is not at all appealing. On the other hand, security screens look excellent and can’t be simply cut since they’re constructed of a durable substance. Additionally, they may feature a sliding deadbolt and even an actual lock.

Security or burglar bars are beneficial, but it’s not ideal for homes if you have children or your house is prone to risks, like flood and fire. You need to find the easiest way out possible if that happens. Unfortunately, that will likely never happen with permanently installed security bars, although some DIY interior window security bars allow for opening.
