Bullet Resistant Glass | 1-8 Interlayer Threat Levels
Bullet resistant glass is designed for projects that require an added layer of protection in commercial, institutional, and select residential applications.
Architectural Glass and Metal provides access to laminated bullet resistant glass options with interlayer threat levels from 1 through 8, depending on the required performance, glass make-up, thickness, and project specifications.
These laminated glass systems can be used for applications such as storefronts, transaction windows, ticket booths, security glazing, reception areas, entry systems, bandit barriers, and other areas where ballistic-resistant glazing may be required.
Available in multiple make-ups, panel sizes, thicknesses, and glass types, bullet resistant glass can help support both security performance and architectural design requirements.
Lightest Interlayers & First-Rate Safety
Bullet resistant glass is manufactured using laminated assemblies that may include combinations of glass, PVB interlayers, and polycarbonate materials, depending on the required threat level and performance criteria.
These laminated systems are designed to provide ballistic-resistant protection while managing overall thickness and weight. This can be especially important for framed applications, windows, entrance doors, and glazing pockets where excessive weight or thickness may limit installation options.
Because every project has different requirements, the final glass makeup should be selected based on threat level, frame compatibility, code requirements, project location, and installation conditions.
Bullet resistant glass can be specified to conform to recognized ballistic performance standards such as UL 752 and NIJ 0108.01, depending on the tested configuration and project requirements.
These standards are commonly used to evaluate ballistic-resistant materials based on ammunition type, weapon class, number of shots, test conditions, and penetration resistance.
The product information referenced for this page notes that these laminated assemblies are designed for no-spall ballistic protection, scratch resistance, and high-velocity impact resistance.

Laminated Make-Ups & Interlayer Thicknesses
Bullet resistant glass is fabricated as a laminated safety glass product, with make-ups selected according to the required threat level and project application.
Available glass types may include:
- Annealed glass
- Heat-strengthened glass
- Tempered glass
Available makeups may include:
- Clear glass
- Tinted glass
- Reflective glass
- Textured glass
- Mirrored glass
Interlayer color options may include:
- Clear
- Gray
- Blue
- Yellow
Overall thickness varies by threat level. In general, higher resistance levels require thicker laminated assemblies. Bullet resistant glass has an optimal thickness of approximately 1” overall , with increased thicknesses used for higher threat levels or specific performance requirements.
Specs: Sizes, Thicknesses, Make-Ups & Colors
Bullet resistant laminated glass can be fabricated in standard and custom panel sizes depending on the selected glass type, threat level, thickness, make-up, and project requirements.
Panel Sizes & Interlayer Thicknesses:
- Max Standard Sheet Sizes: Up to 48″ x 96″
- Custom Panel Sizes: Up to 60″ x 96″
- Interlayer Thicknesses: 1” & up pending threat level
Glass Types, Make-Ups & Interlayer Colors:
- Glass Types: Annealed, heat strengthened & tempered
- Make-Ups: Tinted, reflective, textured & mirrored
- Interlayer Colors: Clear, grays, blues, yellows & more
Common Applications
Bullet resistant glass may be used in a range of commercial, institutional, and residential security applications, including:
- Banks and financial institutions
- Transaction windows
- Ticket booths
- Reception areas
- Security gates
- Storefronts
- Entry systems
- Bandit barriers
- Panic door systems
- Government or administrative facilities
- Retail locations requiring added security
