When burglars attempt a break-in, they target the weakest point—and that’s often your door glass. Standard glass shatters in seconds. Laminated glass doesn’t.
This guide explains why laminated glass has become the security standard in UK composite doors, how it compares to tempered glass, and what British homeowners should know before choosing their door glazing.
What is Laminated Glass?
Laminated glass is safety glass engineered to stay intact when shattered. Unlike standard glass that breaks into dangerous shards, laminated glass holds together—even under repeated impact.
How it’s made
Two or more glass panes are bonded with a tough plastic interlayer (typically polyvinyl butyral, or PVB). When struck, the glass may crack, but the interlayer prevents it from separating. This creates a “spider web” effect that maintains the barrier.
Why composite door manufacturers use it
Laminated glass transforms your door from a vulnerable entry point into a serious security barrier. It meets UK Building Regulations for safety glazing and passes the stringent tests required for PAS 24:2016 certification—the UK police-backed security standard.
Why Laminated Glass Matters for Home Security
Laminated glass doesn’t just meet minimum safety standards—it actively prevents break-ins.
The break-in reality:
Burglars want fast entry. If they can’t smash through your door glass within 30 seconds, most move on. Standard annealed glass shatters instantly. Tempered glass breaks into small cubes that still leave an opening. Laminated glass holds firm—even after multiple strikes.
How laminated glass resists forced entry?
Impact resistance: The PVB interlayer absorbs shock and distributes force across the entire pane. A burglar would need sustained, loud attacks to breach it—exactly what they avoid.
Retention after breakage: Even when the outer glass cracks, the laminated structure stays in the frame. No hand-sized opening appears for reaching through to unlock your door.
Noise deterrent: Breaking laminated glass requires repeated, violent impacts. The noise alone draws attention, forcing intruders to abandon the attempt.
PAS 24:2016 compliance:
To achieve PAS 24 certification—the benchmark for UK door security—composite doors must withstand manual attack testing. Laminated glass is essential for passing these tests. Standard or tempered glass fails immediately.
If your composite door has PAS 24 certification, it almost certainly contains laminated glass in the glazed panels.
Composite Doors
Laminated glass in composite doors enhances security and reduces noise. It also adds an extra layer of insulation, making your home more energy-efficient. Check out our composite doors for stylish and secure options.
UPVC French Doors
Due to having a large amount of glass, using laminated glass in UPVC French doors offers increased safety and is a popular option for homeowners.
Aluminium Bifold Doors
Much like uPVC French doors, laminated glass in aluminium bifold doors provides durability and strength. It also helps improve thermal insulation, keeping your home comfortable year-round. Discover our range of aluminium bifold doors.
Windows
Laminated glass in windows offer better security and noise reduction compared to standard double glazed toughened glass. They are ideal for homes in busy areas or those looking to maximise security.
Roof Lanterns
Laminated glass in roof lanterns is beneficial mainly for safety reasons. One of the advantages of laminated glass is that it holds together when broken. In contrast, toughened glass, while generally safe, would collapse all over your floor!
Benefits of Laminated Glass
Laminated glass offers numerous benefits that make it a superior choice for various applications in your home. Here are some key advantages:
Security
Laminated glass provides enhanced security. Its construction makes it difficult to break, and even if it shatters, the glass remains adhered to the plastic interlayer making it very difficult to get through. This makes it harder for intruders to gain access, providing peace of mind for homeowners.
UV Protection
Often overlooked, laminated glass is capable of blocking up to 99% of harmful UV rays. This protection helps prevent your furniture, flooring, and other interiors from fading, maintaining their appearance and longevity.
Noise Reduction
Another often forgotten benefit is that the plastic interlayer in laminated glass acts as a sound barrier, helping to reduce noise pollution. This is especially beneficial for homes located in busy or noisy areas, ensuring a quieter and more peaceful living environment.
Energy Efficiency
Laminated glass can contribute to better thermal insulation, helping to keep your home warmer in the winter and cooler in the summer. This can lead to lower energy bills and a more comfortable indoor climate.
Safety
One of the most significant benefits of laminated glass is its safety feature. Unlike regular glass, which shatters into pieces, laminated glass holds together when broken. This reduces the risk of injury from flying glass shards.
Durability
Laminated glass is highly durable and can withstand extreme weather conditions, including high winds and hail. This makes it an excellent choice for exposed areas like windows, doors, and roof lanterns.
Versatility
Laminated glass can be used in various home applications, including doors, windows, roof lanterns, and even glass floors or stairs. Its versatility makes it a practical and safe choice for modern homes.
Conclusion
Laminated glass is a smart choice for enhancing the safety, security, and comfort of your home. Its ability to hold together when shattered makes it a superior option for doors, windows, and roof lanterns. You should choose laminated glass for better:
With added benefits like UV protection, noise reduction, and improved thermal insulation, laminated glass not only safeguards your home but also contributes to energy efficiency and aesthetic appeal. Whether you’re upgrading your doors or looking to add value to your property, laminated glass offers a range of advantages that make it a worthwhile investment.
Consider incorporating laminated glass into your home to enjoy these benefits and more.
