THE ULTIMATE GUIDE TO

BURGLAR BARS

Burglar Bars

Burglar bars, also known as security bars or window bars, are physical barriers installed on windows to enhance security and prevent unauthorized access to a building or property. They consist of sturdy bars or grilles that are securely affixed to the window or door frame, forming a protective barrier.

The primary purpose of burglar bars is to deter potential burglars or intruders from gaining entry into a building. By providing a physical obstruction, they make it more challenging for unauthorized individuals to break through windows, thus acting as a deterrent against forced entry.

Where can Burglar Bars be used?

Burglar bars can be used in various locations to enhance security and prevent unauthorized access. Here are some common places where burglar bars can be installed:

Burglar bars are frequently used in residential settings. They can be installed on windows, or any other vulnerable points of entry in houses, apartments, or cottages. By adding burglar bars, homeowners can significantly increase the security of their homes.

Businesses often utilize burglar bars to protect their premises. These bars can be installed on storefront windows or areas containing valuable equipment or inventory. They serve as a physical barrier to deter break-ins and safeguard commercial properties.

Retail establishments often install burglar bars on windows and entry points, particularly in high-risk areas. These bars provide added security during non-business hours while allowing visibility of merchandise, even when the store is closed.

Burglar bars can be used in educational institutions to enhance security. They are commonly installed on windows in classrooms, administrative offices, or areas with valuable equipment to protect against theft or vandalism.

Public facilities, such as government offices, libraries, or community centers, may opt to install burglar bars to secure windows and doors. These bars help prevent unauthorized access and protect valuable assets or sensitive information.

Manufacturing plants, warehouses, or storage facilities often require robust security measures. Burglar bars can be used in these settings to secure windows or other access points, protecting valuable goods and equipment.

Hospitals, clinics, or medical centers may employ burglar bars to enhance security, especially in areas where medications, sensitive equipment, or confidential patient records are stored.

Who can use Trellidor Burglar Bars?

Homeowners looking to fortify their residences against break-ins and unauthorized access can install burglar bars on windows, or other vulnerable entry points. Burglar bars provide an additional physical barrier that helps deter potential intruders and increase home security.

Individuals residing in rental properties can also benefit from burglar bars. With the permission of the landlord, renters can install burglar bars to enhance the security of their rented homes, adding an extra layer of protection and peace of mind.

Commercial establishments such as retail stores, restaurants, and offices can use burglar bars to protect their premises from break-ins and theft. Burglar bars can be installed on windows, or storefronts to prevent unauthorized entry and secure valuable assets.

When to use Burglar Bars

RESIDENTIAL PROPERTIES

Burglar bars are commonly used in residential properties to protect homes, apartments, or residential estates. They can be installed on ground-level windows, basement windows, or other vulnerable entry points. Residential properties often benefit from the added security and peace of mind that burglar bars provide.

COMMERCIAL PROPERTIES

Burglar bars are also applicable to commercial properties such as offices, retail stores, warehouses, or any business premises that require enhanced security. They can be used on windows, or even storefronts to prevent unauthorized access during non-business hours or when the premises are unoccupied.

HOLIDAY HOMES OR SEASONAL RESIDENCES

If you own a holiday home or have a seasonal residence that remains unoccupied for extended periods, burglar bars can be valuable. These properties are often more susceptible to break-ins due to their temporary vacancy. Installing burglar bars can provide an added layer of protection during the property’s unoccupied periods.

HIGH-CRIME AREAS

If you live or operate a property in an area with a high crime rate, burglar bars can be particularly useful. These areas are often targeted by burglars, and having visible security measures like burglar bars can act as a strong deterrent and increase the overall security of your property.

GROUND-LEVEL OR EASILY ACCESSIBLE WINDOWS

Any windows or entry points that are easily accessible from the ground, such as basement windows or windows near trees or flat roofs, are potential targets for burglars. Installing burglar bars on these vulnerable points can significantly reduce the risk of unauthorized entry.

PROPERIES WITH PRIOR SECURITY BREACHES

If your property has experienced a previous security breach or break-in, installing burglar bars can provide a proactive security measure to prevent future incidents. It serves as a visible reminder that the property is secured, deterring potential burglars.

PRODUCT COMPARISON

Fixed Security vs Retractable
for your Windows

Fixed security gates for windows are permanently attached to either the window frame or to the wall around the window and does not move. These burglar bars can only be removed by unscrewing them. If you do this, you are left with no protection from criminals.

Retractable security gates for windows are burglar bars that can be opened without being removed. They do not have to be unscrewed or weakened in any way. The frame stays attached to the wall around the window but the burglar proofing inside the frame can be unlocked and opened or closed and locked as needed.  READ MORE

Steel Burglar Bars vs Transparent Burglar Bars

Polycarbonate is a virtually indestructible material, which is the primary reason why it is used in high demand applications such as cockpits of fighter jets, shields used by riot control police, Formula One cars, and high-speed trains. Polycarbonate boasts a high tensile strength and its burglar bars are also flexible and highly impact resistant. Even cutting the bar at a single point won’t provide access, as the part will snap back into its place.

Steel bars, arguably are the most common type of burglar bars. Steel bars feature a simple design, are durable and inexpensive. Unlike many other materials, steel does not easily twist, bend, or break. Steel bars are a potent deterrent for burglars. The more time a burglar spends on a property, the higher their chances of getting caught. Cutting and removing a steel bar takes time, which is why an average burglar would prefer targeting a home with unsecured windows. READ MORE

Cottage Guard vs
Burglar Guard

Cottage Guard is made from square aluminium tubing reinforced internally. They have horizontal and vertical square bars that cross each other. They look similar to cottage pane windows. Each unit is fully framed, meaning the frame is on all four sides of the burglar bar.

Burglar Guard is made from galvanised steel oval shaped tubing. The tubes are joined together in one of three ways: a single trellis pattern; a double trellis pattern; or flat bars without trellis, which can be installed horizontally or vertically. The units are semi-framed, meaning the frame is on two sides of the burglar bar. READ MORE

Louvre Shutters vs
Burglar Bars

Window security product choices today are far more varied than they used to be in the days of plain metal bars attached to steel window frames. Nowadays there is a wide range of material and style, which can be confusing. What you consider the best for your window security will depend on whether you are looking for the best price, the best protection or both.

Two of the most popular options are burglar bars and security shutters, each of which have particular benefits and features. Take a look at the pros and cons of both types before you make up your mind about which is best for your home. READ MORE
