Unbreakable Views: The Security Features of Modern Architectural Glazing

For UK homeowners investing in premium architectural glazing—be it expansive sliding doors, sleek bifold doors, or contemporary rooflights—the aesthetic appeal and natural light benefits are often the primary drivers. However, paramount to any home improvement project is security. At Shard Architectural Glazing, we understand that true luxury means absolute peace of mind. Modern glazing systems are far more than just glass and aluminium; they are sophisticated barriers designed to withstand intrusion.

This comprehensive guide explores the cutting-edge security features integrated into today’s high-performance glazing. We delve into everything from the strength of the glass itself to the complexity of the locking mechanisms, ensuring your beautiful new installation doesn’t compromise the safety of your home.

The Foundation: Secure Glazing Materials

The glass itself is the largest component of any glazing installation, making its composition critical to overall security. Gone are the days when standard annealed glass was sufficient. Modern architectural glazing relies on specialised glass types engineered for resilience and resistance to impact.

Laminated and Toughened Glass

Laminated glass is often the gold standard for security. It consists of two or more panes of glass bonded together by an interlayer, typically Polyvinyl Butyral (PVB). If the glass is struck and breaks, the PVB interlayer holds the shards firmly in place, preventing a large hole from forming and maintaining the integrity of the barrier. This makes forced entry significantly more difficult and time-consuming, acting as a powerful deterrent.

Toughened glass (also known as tempered glass) is standard in most modern installations due to its strength. It undergoes a heating and rapid cooling process, making it four to five times stronger than standard glass. While toughened glass will shatter under extreme force, it breaks into small, relatively harmless granules, reducing the risk of injury—though for high-security applications, laminated glass is preferred or used in conjunction with toughened glass.

Advanced Locking Mechanisms and Hardware

A window or door is only as secure as its locking system. Shard AG specifies systems that utilise sophisticated, multi-point locking mechanisms, which engage at several points along the frame simultaneously when the door or window is closed and locked. This distributes the pressure across the entire frame, making it incredibly difficult to pry open.

Multi-Point Locking Systems

For large format products like our premium sliding doors and bifold doors, multi-point locking is essential. These systems typically include a combination of hook bolts, shoot bolts, and compression points (mushrooms or rollers) that securely anchor the moving panel to the frame or to the adjacent static panel. The sheer mechanical complexity and strength of these locks are a major deterrent to opportunistic burglars.

Cylinder and Handle Security

The lock cylinder is the vulnerable point often targeted by criminals using techniques like 'lock snapping'. Modern, high-security glazing systems incorporate cylinders that meet stringent standards, such as the TS007 3-star rating or the Sold Secure Diamond standard. These cylinders are designed to resist snapping, drilling, picking, and bumping. Furthermore, the handles themselves are often designed to be robust, sometimes incorporating features that prevent the internal mechanism from being manipulated from the outside.

Frame Integrity and Design

The strength of the frame material and the way the glass is secured within it play a crucial role in preventing forced entry. Aluminium, the material of choice for premium architectural glazing, offers exceptional strength-to-weight ratio and inherent rigidity.

Aluminium Strength and Slim Profiles

While homeowners often seek the slimmest possible sightlines for maximum views, this does not equate to reduced security. High-quality aluminium frames, like those used by Shard AG, are structurally robust. The profiles are internally reinforced and designed specifically to house the deep-set glass units securely. Crucially, the way the glass is beaded (secured into the frame) is often internal, meaning the glass cannot be removed from the outside—a common weakness in older window designs.

Secure Track Systems for Sliding Doors

For sliding doors, the track system is vital. Modern high-security sliders feature anti-lift mechanisms. These are cleverly designed components that engage when the door is closed and locked, preventing the panels from being lifted off the track from the outside, thereby eliminating a traditional point of attack for large glazed doors.

"The security features on our new Shard sliding doors are incredible. We have a huge expanse of glass, but knowing it has laminated glass and the multi-point locking system meets the highest UK standards gives us complete confidence. The installation team were meticulous about the security checks."

— Mr. & Mrs. Davies, Surrey

Industry Standards and Certifications: What to Look For

In the UK, security standards provide a clear benchmark for assessing the performance of glazing products. Homeowners and specifiers should always look for products that comply with recognised industry certifications, ensuring the system has been independently tested against realistic attack methods.

PAS 24 and Secured by Design

The most important standard for residential doors and windows is PAS 24: Enhanced Security Performance Requirements for Doors and Windows. A product certified to PAS 24 has been tested to resist common methods of forced entry, including manipulation, cutting, and impact. Choosing a PAS 24 certified product guarantees a baseline level of security performance.

The Secured by Design (SBD) initiative, backed by the UK Police, goes a step further. SBD accreditation is only granted to products that have been tested and certified to meet the highest security standards (often exceeding PAS 24) and incorporate effective crime prevention features. Shard AG prioritises systems that achieve SBD status, offering our clients maximum assurance.

Integrating Smart Technology for Enhanced Protection

Beyond the physical barriers, modern glazing seamlessly integrates with smart home security systems, adding layers of electronic protection and monitoring. This combination of mechanical strength and electronic intelligence offers the highest level of home defence.

Integrated Sensors and Monitoring

Many premium glazing systems can accommodate discreet magnetic sensors within the frame profiles. These sensors connect directly to your alarm system, detecting if a door or window is opened or tampered with. Because they are hidden within the frame, they maintain the sleek aesthetic of the architectural glazing while providing instant alerts.

Access Control and Automation

For large, heavy sliding doors, automated systems are increasingly popular. These systems often include sophisticated electronic locking mechanisms that are controlled via keypads, biometrics, or smart phone apps. This not only enhances convenience but also provides a traceable record of access and ensures the door is always fully secured when closed.
