Defense and Security

Armored glass

Armored glass is designed to provide the highest level of protection and security for people and property in private homes, commercial premises, sensitive targets, or vehicles.

It consists of laminated glass made with multiple layers of glass and plastic interlayers.
Standard UNI 7697 sets the performance parameters that bulletproof glass must meet in order to be classified as anti-vandalism glass and anti-burglary glass (DIN EN 356) or as bullet-resistant glass (UNI EN 1063).

Anti-vandalism and anti-burglary glass

Standard UNI EN 356 (“Testing and classification of resistance against manual attack”) classifies laminated safety glass based on its resistance to external forces. It defines two categories of glass through different testing methods:

• Anti-vandalism glass
• Anti-burglary glass

Anti-vandalism glass

Standard requirements

Resistance to vandalism is tested by a drop test using a hard object: a steel ball approximately 100 mm in diameter and weighing about 4.11 kg is dropped from various heights. All three test samples must prevent penetration by the impact body.

Based on this test, anti-vandalism glass is classified into five categories, in ascending order of performance:

• Anti-vandalism glass P1A
• Anti-vandalism glass P2A
• Anti-vandalism glass P3A
• Anti-vandalism glass P4A
• Anti-vandalism glass P5A

Test Conditions for Anti-vandalism Glass

Anti-burglary glass

Standard requirements

Resistance to burglary is classified using the so-called axe test, in which all three test samples must withstand at least the minimum number of blows required to create an opening. The axe head weighs around 2 kg and is made of forged steel.

Based on this test, anti-burglary glass is classified into three categories, in ascending order of performance:

• Anti-burglary glass P6B
• Anti-burglary glass P7B
• Anti-burglary glass P8B

Test Conditions for Anti-burglary Glass

Examples of Applications
Anti-vandalism and anti-burglary glass is used in museum display cases, showcases for jewelry and luxury goods, banks, post offices, framed artwork, and private collections.

Veneto Vetro’s Offering
Veneto Vetro produces anti-vandalism and anti-burglary glass that meets the requirements of all resistance classes.

Bullet-resistant glass

Standard requirements

Bullet-resistant glass is tested according to the European standard UNI EN 1063. This standard defines performance requirements and test methods to classify the resistance of glazing and glass/plastic composite panels to bullets.

Three shots are fired at the test sample in the shape of an equilateral triangle with 100 mm sides. The test is passed if at least one of the following criteria is met:

• No penetration of the glass or glass fragments on the rear side, and no perforation of the witness screen – classified as “NS” (No Spall).
• No penetration by the bullet, but fragmentation perforates the witness screen – classified as “S” (Spall).

Seven classes are defined for pistol and rifle fire:

• Bullet-resistant glass BR1
• Bullet-resistant glass BR2
• Bullet-resistant glass BR3
• Bullet-resistant glass BR4
• Bullet-resistant glass BR5
• Bullet-resistant glass BR6
• Bullet-resistant glass BR7

And two additional classes for shotgun fire:

• Bullet-resistant glass SG1
• Bullet-resistant glass SG2

Available in both “spall” and “no spall” versions

Classification and Test Requirements for Bullet-Resistant Glazing (Pistols and Rifles)

Examples of Applications

Bullet-resistant glass is widely used in buildings: private homes, glass partitions and entryways in banks, post offices, courthouses, public buildings, and showcases in luxury and jewelry shops.
Another important field of application is transport: windows for vans and armored vehicles, cash-in-transit vehicles, and military vehicles.

Veneto Vetro’s offering

Veneto Vetro has certified two different families of bullet-resistant glass:

HeroShield is a family of bullet-resistant glass composed of various combinations of glass and plastic layers, optionally with anti-spall film, covering resistance classes from BR2 to BR6 (both “spall” and “no spall” versions).

TitanShield is a bullet-resistant glass family that incorporates a final polycarbonate layer to reduce overall glass thickness and improve optical quality, while maintaining resistance performance in classes BR4 to BR6 (both “spall” and “no spall” versions).
