Bullet-proof windows

Bullet-proof windows with EN 1063 certified glazing (BR1 to BR7)

Bullet-proof windows are protected service window systems designed for public-facing environments where controlled interaction and ballistic protection are required. These solutions are typically specified for banks, embassies, government facilities, security companies and other high-exposure service points, combining a reinforced frame system with bullet-resistant glazing certified to EN 1063.

What EN 1063 certification means for glazing

EN 1063 is the European standard used to classify the ballistic resistance of security glazing. Glazing is classified into BR1 to BR7 (and, separately, SG1 to SG2 for shotgun threats). The correct class is selected based on the threat assessment, operational environment and the overall protected counter design.

EN 1063 glazing classes: BR1 to BR7

Below is a practical overview of the BR classes to help define the right protection level. The final specification should always be confirmed at project level, because glazing build-ups and integration details depend on the installation.

BR1

Entry-level bullet-resistant glazing class within EN 1063. Typically specified where the risk profile is lower and where a basic ballistic barrier is required.

BR2

Designed for enhanced resistance against common handgun threats. Often selected for exposed public-facing counters that require a stronger baseline than BR1.

BR3

Higher handgun resistance class used in service environments with increased risk of armed assault and higher-impact handgun threats.

BR4

Upper handgun resistance class within the BR range. Frequently specified for high-exposure counters where stronger handgun protection is required.

BR5

Rifle-resistance class typically associated with long-weapon threats. Used in environments with higher threat assessments and stricter protection requirements.

BR6

Higher rifle-resistance class. Often selected for critical infrastructure and high-risk service points requiring stronger protection against long-weapon threats.

BR7

Top class within the BR range. Commonly specified for the highest-risk environments and protection profiles, including scenarios requiring resistance against more severe rifle threats.

Other EN 1063 classes: SG1 and SG2 (shotgun)

In addition to BR classes, EN 1063 includes SG1 and SG2 classifications for shotgun-related threats. These are specified when the threat assessment includes shotgun munitions and the project design requires that protection profile.

System integration matters

Ballistic glazing performance depends not only on the glass but also on how it is integrated into the frame and service window system. For this reason, bullet-proof windows are specified as a complete solution (glazing, frame, fixings, and counter integration) rather than as glazing alone.

Options for protected service windows

Depending on the project, bullet-proof windows can be specified together with complementary components to create a complete protected counter:

• Intercom Systems for clear two-way communication through protected barriers.
• Transfer Trays for controlled drawer-based exchange of documents and cash.
• Pass-Through Trays for open tray-style exchange in protected counters.
• Dispenser Counters for integrated service counter solutions.

Installation guidance

Bullet-proof windows should be installed by qualified professionals. Correct anchoring, frame fixing and glazing integration are essential to ensure that the specified EN 1063 class is maintained in real-world conditions.

FAQs

Which BR class should I choose?

The correct BR class depends on the threat assessment, the service environment and the overall system design. Share your use case and we will recommend the most appropriate specification.

Is EN 1063 certification only about the glass?

EN 1063 classifies glazing, but real performance depends on correct system integration into frames and counter structures. That is why project-level specification is important.

Can bullet-proof windows be combined with transfer systems and intercoms?

Yes. Bullet-proof windows are often part of a complete protected service counter solution, combined with exchange trays and communication systems.
