Security glass: which options to choose?

An elegant opening… but must be secured

Bay windows have become an essential part of contemporary architecture. They offer luminosity, openness to the outside world and modern aesthetics, while enhancing living spaces. But this large glass surface also represents a sensitive point of entry for burglars, particularly when it’s located on the garden level, where it’s difficult to see or poorly protected.

To combine comfort and security, it’s essential to choose the right security options for your bay window, depending on its location, use and level of risk. Here’s an overview of the solutions available, from the simplest to the most advanced.

1. Choosing the right safety glass

The first line of defence for a bay window is the glazing itself. Unsecured single or even double glazing can be broken quickly. That’s why it’s crucial to opt for burglar-resistant laminated glass, certified to EN 356.

The most common resistance classes for residential use :

P2A: good protection against accidental breakage and rapid attempts.
P4A: delays break-in, resists several violent blows (ideal for private homes).
P5A and above: recommended for commercial showcases or detached housing.

This type of glazing remains in place even after several impacts, preventing any direct intrusion.

2. Reinforcing joinery and closures

Glazing alone is not enough. The frame and locking systems must also be secured:

Reinforced frame: aluminum or PVC with internal metal structure.
Multi-point locking: with top and bottom bolts to prevent unlocking.
Handle with integrated lock: to prevent opening from the inside by glass breakage.
Reinforced sliding stop: to secure the opening even when it is lifted.

These elements ensure complete mechanical strength, which is difficult to break in quickly.

3. Integrating a shutter or mobile protection system

Roller or sliding shutters provide an extra layer of security, especially at night or when you’re away for long periods. For a bay window, we recommend :

a motorized roller shutter with automatic locks,
anti-tear slides,
an extruded aluminum door leaf (more resistant than PVC),
or solid sliding shutters, attractive and sturdy.

A security shutter prevents glass breakage and direct access.

4. Installing an alarm or connected sensors

To complete the physical security, it is a good idea to add an alarm connected to the bay:

opening or impact sensor on the glass,
magnetic contact on closure,
exterior or interior camera facing the bay,
home automation scenarios: automatic shutter closing at certain times, motion detection, presence simulation.

These devices increase responsiveness to attempted break-ins and discourage opportunistic intrusions.

5. Opt for flame-retardant or solar-control glazing (as required)

In some cases, the bay window may also be exposed to particular risks:

flame-retardant glazing, for homes in dense urban areas,
solar control glazing, to limit overheating while maintaining safety.

These options can be combined with burglar-resistant glazing for multifunctional protection.

Professional installation, a guarantee of performance

Whatever level of security you choose, the reliability of the system depends largely on the quality of the installation. A poorly secured bay window or poorly installed glazing will lose its effectiveness, even if it is certified.
