All Plastic
As a no spall bullet-resistant laminate, an All Plastic laminate is made entirely of specially engineered plastics that are bonded together with adhesive interlayers. There are two types of All Plastic constructions: (1) acrylic plastic core with a polycarbonate layer laminated to each side or (2) polycarbonate core(s) with a polycarbonate layer laminated to each exterior side. The exposed polycarbonate layer has an abrasion resistant coating on its surface for the purpose of providing excellent abrasion and chemical resistance. These offer exceptional bullet-resistance and support applications that require no spalling.
The benefits of All Plastic laminates include high clarity, lightweight construction, improved resistance to forced entry, and minimal risk of injury from flying debris. This type of laminate is designed for use in buildings or structures and is not suitable for outdoor environments or applications where it might be exposed to the elements. All Plastic laminates are often used in areas like school and office reception areas, security checkpoints, shopping malls, and gas stations where safety is a concern.
Make-Up Features
Acrylic
Thompson utilizes an optical grade bullet-resistant Acrylic plastic, a thermoplastic material known for its clarity, durability, strength and ability to withstand a bullet. Acrylic goes by various other trade names, such as Plexiglas or Lucite, and like Polycarbonate is a high transparent thermoplastic material. The acrylic properties are designed to deform and dissipate the energy of a bullet and prevent it from passing through.
Polycarbonate
Thompson utilizes an optical grade Polycarbonate, a thermoplastic material known for its clarity, durability and strength. They are responsible for absorbing and dispersing the energy of the bullet or projectile upon impact. Compared to a regular glass product, Polycarbonate’s strength makes it less likely to shatter upon impact which is an essential factor in the performance of the glass and the application. The exposed polycarbonate layers have an abrasion resistant coating on its surface for the purpose of providing excellent abrasion and chemical resistance. Take special care and follow specific instructions when cleaning polycarbonate as permanent damage may result if cleaned incorrectly.
Adhesive Interlayers
Thompson uses high optical grade thermoplastic polyurethane (TPU) to bond multiple layers of acrylic and/or polycarbonate. The interlayers act as the “glue” that hold the various layers together. TPU is known for its adhesion, flexibility and ability to absorb impact energy, making it appropriate for use in bullet-resistant glass constructions.
Ballistic Protection
The below chart refers to how much ballistic protection the Thompson Innovative Glass product provides, based on standardized testing. In the U.S., bullet-resistant glass is rated by UL 752 the standard for bullet-resistant materials set by Underwriters Laboratories (UL).
It defines testing methods and performance criteria for bullet-resistant glass, doors, panels, and other protective materials. and classified into a range of levels.

Applications-Security and Protection
Bullet-resistant and forced entry glass are critical components in protecting people and property across a wide range of high-risk environments. These specialized glazing solutions are trusted wherever enhanced security and peace of mind are essential, from public institutions to private facilities. Common applications include:
Gas Stations
Security glazing at gas stations protects against theft and vandalism while allowing for clear visibility and customer interaction at transaction points.
Convenience Stores
These retail spaces utilize protective glass to deter crime and protect staff, particularly during overnight hours or high-traffic periods.
Pharmacies
Pharmacies benefit from secure transaction windows and interior glazing that prevent theft and ensure controlled access to medication.
Ticket Counters
Secure glazing at ticket windows protects staff while allowing for efficient and safe customer interaction in arenas, transit stations, and entertainment venues.
Drive Up Windows
Glass at drive-thru locations must offer clear communication, impact resistance, and ease of service—often with ballistic or security ratings.
Financial Institutions
Banks and financial offices rely on secure glazing for transaction windows, teller areas, and entry points to protect employees and assets.

Frequently Asked Questions About Bullet-Resistant Glass
What is bullet-resistant glass?
Bullet-resistant glass, also known as ballistic glass, is a type of reinforced glass designed to resist penetration from bullets. It typically consists of multiple layers of glass and polycarbonate materials, laminated together to absorb and disperse the impact of projectiles.
How does bullet-resistant glass work?
When a bullet strikes the glass, the outer layer absorbs the impact, while the inner layers dissipate the energy and prevent penetration. The polycarbonate layers add flexibility and strength, ensuring the glass remains intact even after repeated hits.
Is bullet-resistant glass completely bulletproof?
No material is entirely bulletproof. Bullet-resistant glass is designed to slow or stop specific calibers of bullets based on its rating. Over time or with repeated impacts, even high-rated glass may fail.
What are the levels of bullet-resistance?
Bullet-resistant glass is rated according to standards such as the UL 752 in the U.S. or EN 1063 in Europe. These levels indicate the glass's ability to withstand specific types of firearms and ammunition.
Where is bullet-resistant glass typically used?
- Banks and financial institutions
- Government buildings
- Schools and universities
- Retail stores (especially jewelry or high-value merchandise)
- Private vehicles and armored transport
- Security booths and checkpoints
Can bullet-resistant glass be installed in existing structures?
Yes, retrofitting is possible. Bullet-resistant glass can be customized and installed in existing frames, though structural modifications may be required for proper support.
Does bullet-resistant glass look different from standard glass?
Modern bullet-resistant glass is designed to look clear and similar to standard glass. Some thicker or higher-rated options may have a slight tint due to the layers of materials.
How thick is bullet-resistant glass?
Thickness depends on the level of protection, ranging from 0.25 inches (Level 1) to over 2 inches (Level 8). Higher levels of protection generally require thicker glass.
Can bullet-resistant glass be combined with other features?
Yes, bullet-resistant glass can include additional properties like:
- Energy efficiency with low-E coatings.
- Fire resistance for enhanced safety.
- Privacy options like tinting or one-way visibility.
And now via Thompson Innovative Glass- we offer Bird Friendly properties with Bullet Resistant Glass.
How much does bulletproof glass cost?
Bullet-resistant glass typically costs 100% to 400% more than standard commercial glazing.
Pricing varies based on:
- Threat level (UL 752 Level 1–8)
- Glass type (all-glass, laminated, or glass-clad polycarbonate)
- Size, thickness, and installation needs
While more expensive, it provides vital protection in schools, government buildings, banks, and other high-risk environments.
What is bulletproof glass made from?
Bullet-resistant glass is made from multiple layers of glass and plastic (polycarbonate or PVB interlayers). These layers absorb and slow down bullets, dispersing the energy and preventing penetration.
How is bulletproof glass made?
At our state-of-the-art facility in Jenison, MI, bullet-resistant glass is fabricated by:
- Tempering or heat-strengthening the outer glass for durability.
- Layering sheets of glass and plastic.
- Laminating them under heat and pressure in an autoclave.
- Precision bonding for optical clarity and resistance.
The result is a strong, transparent barrier that can stop bullets while still functioning as a window.
How thick is bulletproof glass?
The thickness varies by protection level:
- Level 1 (handguns): ~1-1/8" thick
- Level 3 (high-powered handguns): ~1-1/4" thick
- Level 8 (rifles): can exceed 2"+
We offer several options depending on the security need, including all-glass and hybrid glass-polycarbonate constructions.
