Double glazing is well known for its energy-efficient properties, but its impact on home security is often a less discussed benefit. In recent years, more Australians have been opting for double-glazed windows as a means of improving insulation, reducing energy bills, and increasing comfort.
However, one question that homeowners frequently ask is whether double-glazing can also enhance the security of their homes. In this article, we’ll explore the security advantages of double glazing, how it works, and whether it should be a primary consideration when deciding on home improvements.

What Is Double Glazing?
Before diving into the security benefits, it’s important to first understand what double glazing is. Double glazing refers to windows that consist of two panes of glass separated by a layer of air or gas (usually argon). The purpose of this structure is primarily to improve thermal insulation, making homes more energy-efficient by reducing heat loss in winter and keeping cool air inside during summer.
The gap between the two panes acts as a buffer against the external temperature, leading to more stable indoor climates.While double glazing is often associated with energy savings, its thicker glass and increased structural strength also provide additional benefits, including soundproofing and, to a certain extent, improving the security of a home.
How Double Glazing Improves Security
Increased Glass Thickness
One of the primary ways double glazing can improve security is by increasing the thickness of the glass itself. Single-glazed windows are relatively easy to break, and they can often be shattered by an intruder with minimal effort—whether using a blunt instrument or a quick strike. Double-glazed windows, however, have two layers of glass that are far more resistant to impact.
Though not completely impervious to breaking, the combination of two glass panes and the space between them makes it more difficult for intruders to gain access quickly. Breaking through double-glazed windows requires more force, and most burglars prefer to avoid the noise and effort of trying to shatter multiple layers of glass.
Toughened Or Laminated Glass
In many cases, double-glazed windows use toughened or laminated glass for added durability. Toughened glass, also known as tempered glass, is heat-treated to make it much stronger than standard glass. Laminated glass, on the other hand, has a layer of plastic between two glass panes, which makes it far more resistant to shattering.
This kind of glass holds together even when broken, meaning an intruder would find it much harder to completely penetrate the window.Both of these types of glass are commonly used in double-glazing to enhance security. By opting for double glazing with toughened or laminated glass, homeowners can increase the resistance of their windows to breakage and reduce the likelihood of a successful break-in.
Reduced Window Vulnerability
Many burglars enter a home through a window because it is an easy target. A single-glazed window can be easily opened or smashed to gain access. In contrast, double-glazed windows tend to be more robust and difficult to open or tamper with. For added security, many double-glazed windows also come equipped with multi-point locking systems, which make it even harder for a burglar to open the window from the outside.
These features significantly reduce the chances of an intruder breaking in through a window.
Additionally, the increased strength of double-glazed windows means they are less prone to being damaged by extreme weather conditions, like storms or hail, which could potentially leave your home vulnerable if you rely on weaker, single-glazed windows.
Better Noise Resistance Can Act As A Deterrent
One of the less obvious benefits of double glazing is its ability to reduce noise. This can, in some cases, serve as an indirect security feature. Burglars often prefer to work under the cover of silence, hoping that their movements won’t be heard by residents or neighbours. Double-glazed windows, with their noise-reducing properties, can make it much harder for an intruder to move about undetected.
In a scenario where a burglar tries to break into a home at night, the reduced noise levels provided by double-glazing windows make it more difficult for the intruder to operate quietly, increasing the likelihood of attracting attention and discouraging break-ins.
Increased Privacy
Double glazing also offers better privacy, which can enhance security. Many double-glazed windows come with additional coatings or tints that make it harder for people to see inside.
This added level of privacy makes it more difficult for a potential intruder to gauge whether anyone is home or if valuable items are in plain sight. Since burglars often rely on knowing that a property is unoccupied to strike, the improved privacy offered by double-glazing could make your home a less appealing target.
Enhanced Energy Efficiency
While not directly related to security, the enhanced energy efficiency of double-glazed windows can indirectly deter burglars. Homes with double glazing tend to be more comfortable year-round, meaning you’re more likely to be at home during the day rather than out at work or on vacation. A house that appears consistently occupied is less likely to be targeted by burglars looking for easy opportunities.
Are There Other Security Measures For Windows?
While double glazing undoubtedly provides a degree of security, it is not a standalone solution. Burglars can still find ways to break into homes, and in many cases, additional security measures will be necessary. Here are some additional steps that can improve the overall security of your home:
Reinforced Locks
Installing high-quality locks on your double-glazed windows will further enhance their security. Opt for multi-point locking systems that secure the window in several places, making it much harder to force open. Additionally, some locking systems include key-operated bolts or security pins, which can prevent windows from being opened from the outside.
Security Grills Or Bars
For homes in high-risk areas, security grills or bars can provide an extra layer of protection. These can be installed over windows to make it even more difficult for a burglar to enter. While this may not be the most aesthetically pleasing option, it is one of the most effective security measures.
Window Alarms
Window alarms are another excellent addition to your home security system. They are triggered when the window is opened or broken, alerting you to potential intruders. When combined with double-glazed windows, these alarms create a strong deterrent against break-ins.
Cctv Cameras
Installing CCTV cameras around your property is another way to enhance security. Visible cameras can act as a deterrent, and the footage can be used to identify any suspicious activity.
External Lighting
Burglars are less likely to target homes that are well-lit. Installing motion-activated lights around your windows and doors can help reduce the risk of a break-in. The bright lights can startle intruders and alert neighbours or passers-by to potential criminal activity.
Conclusion
While double glazing is primarily known for its energy efficiency benefits, it does indeed have a positive impact on home security. The combination of thicker glass, tougher materials, and improved insulation makes double-glazed windows more resistant to breakage, tampering, and break-ins.
However, it is important to recognise that double glazing alone cannot guarantee complete security. It should be viewed as part of a broader security strategy, which includes installing reinforced locks, window alarms, security cameras, and proper lighting.
In summary, double glazing is a valuable investment not only for enhancing comfort and energy efficiency but also for providing an added layer of security for your home. Whether you’re upgrading existing windows or building a new home, considering double glazing as part of your security plan can be a wise decision for any homeowner looking to improve safety and peace of mind.
Frequently Ask Question
How Does Double Glazing Make Windows More Secure?
Double glazing improves security by making windows more resistant to breakage. The two layers of glass are held together by a spacer, and this makes it harder for an intruder to shatter the window quickly. In some cases, laminated glass can be used in double-glazed windows, which further strengthens them, making them much more difficult to break through.
Is Double Glazing Enough To Prevent Break-Ins?
While double glazing adds an extra layer of security, it is not a foolproof solution on its own. It can make it harder for burglars to break in, but it should be part of a broader security system. This includes strong window locks, security alarms, motion sensors, and even security screens. Combining these features provides a much stronger deterrent.
What Type Of Double Glazing Is Best For Security?
For improved security, double glazing with laminated glass is the best option. Laminated glass consists of two layers of glass with a plastic interlayer, making it much harder to shatter. This type of glazing is commonly used in high-security situations, such as banks and government buildings, and provides an added level of protection against break-ins.
