How Secure Are Modern Windows? Locks, Glass and Frame Technology Explained
Security is one of the top concerns for homeowners — and rightfully so. Windows are potential entry points for burglars, so choosing products with robust technology and smart features is essential. With advances in locking mechanisms, reinforced glass and connected home security systems, modern windows aren’t just stylish — they’re engineered to protect your home and your peace of mind. In this guide, we’ll break down the key technologies that make today’s windows secure, including the Kubu Smart Security system offered by Kingfisher Windows.
🔐 1. Advanced Locking Systems: First Line of Defence
One of the most significant improvements in modern windows is the multi-point locking system. Unlike old single-point locks that secure only one part of the window, multi-point locks engage at several places along the frame, making it much harder for intruders to force the window open.
For example, Kingfisher Windows products can be fitted with Kubu Smart-upgrade-ready locks, giving homeowners an extra layer of control and integration with smart home tech. These advanced locks work seamlessly with the Kubu system to monitor and report lock status through a mobile app — so you can check whether your windows are securely locked no matter where you are.
Additionally, high-security locking systems are often tested to PAS 24 security standards and can carry Secured by Design accreditation, which means they’ve passed rigorous testing against forced entry attempts.
🪟 2. Toughened and Laminated Glass: Strength That Matters
Glass isn’t just about letting light in — it plays a big role in window security too. Ordinary glass can shatter easily, allowing quick access for an intruder. Modern windows offer toughened and laminated glass options that are far more resistant to impact:
- Toughened Glass is heat-treated so it’s up to five times stronger than standard glass. If it does break, it shatters into small, blunt pieces rather than sharp shards, making entry much harder.
- Laminated Glass has a strong plastic interlayer that keeps the pane bonded even if cracked — meaning the glass stays in place and delays access long enough to deter most break-in attempts.
Both options dramatically improve safety and security, especially for ground-floor windows or accessible areas.
🏠 3. Sturdy Frames and Internal Beading
A window is only as secure as its weakest point — and the frame matters. Modern frames use reinforced uPVC or aluminium, often with internal steel reinforcement to resist tampering and warping.
Another important detail is internal glazing beading. Older windows sometimes have external beading, which can be removed from the outside to pop out the glass pane. Today’s secure windows place the beading inside the frame, meaning only someone inside the home can remove it — a simple but effective deterrent.
📱 4. Smart Security Integration — Like Kubu by Kingfisher Windows
The future of window security isn’t just physical — it’s digital too. The Kubu Smart Security system integrated with Kingfisher’s windows and doors gives homeowners real-time remote monitoring via a smartphone app.
With Kubu, you can:
- Check if windows and doors are locked or unlocked
- Get instant alerts if something is tampered with
- Schedule notifications that fit your lifestyle
- Even integrate with smart home devices like Alexa or Google Home for extended automation features*
This combination of physical security and smart monitoring brings peace of mind, especially when you’re away from home.
✔️ 5. Certifications You Can Trust
When choosing secure windows, look for:
- PAS 24 compliance – ensures resistance to forceful entry
- Secured by Design accreditation – a UK police-backed certification for high security
- Accreditation and testing reassure you that your investment isn’t just strong in theory, it’s proven in practice.
Final Thoughts
Modern windows are far more than decorative openings — they’re engineered systems that combine robust locks, reinforced glass, strong frames and, increasingly, smart technology to guard your home. With solutions like the Kubu Smart Security system from Kingfisher Windows, you can enjoy the comfort and style of new windows without compromising on safety — and with the added peace of mind of real-time monitoring at your fingertips.
