Where Kontek Glass Makes a Difference

Ballistic glazing strengthens the most vulnerable openings in both public and private facilities. Whether protecting personnel, controlling access, or securing high-value assets, the right system must perform without compromising visibility or operations.

Common Applications Include:

Bank and credit unions
Retail and commercial storefront glazing
Government and municipal buildings
Courthouses and law enforcement facilities
Schools and administrative offices
Places of worship
Industrial and utility control rooms
Corporate headquarters

Insights & Information:

What is Ballistic Glass?

Ballistic glass, also called bullet-resistant or bulletproof glass, is a type of security glass made to withstand strong impacts from firearms and other dangerous objects. It’s constructed by layering materials like polycarbonate with glass to create a tough, clear surface that absorbs and spreads the force of bullets or hits, preventing breakage or penetration.

Three common types of bulletproof glass include Acrylic, Polycarbonate, and Glass-Clad Polycarbonate (GCP). You’ll often find ballistic glass in places that need extra protection, like banks, government buildings, schools, and other high-security locations.

Understanding Ballistic Glass Ratings

UL-752 is a widely recognized standard developed by Underwriters Laboratories (UL) that classifies and tests the ballistic resistance of transparent materials commonly used in security applications. The UL-752 standard consists of multiple levels, ranging from Level 1 to Level 10, with each level indicating a different degree of protection against various ballistic threats.

The testing process involves subjecting the materials to controlled firing of specific ammunition types at varying distances and angles, including handguns, rifles, and shotguns. The materials are evaluated based on their ability to withstand penetration, spall (fragmentation), and deformation.

The importance of these ratings cannot be overstated. When it comes to protection, the difference between an adequate rating and an insufficient one can mean the difference between life and death. At Kontek Industries, we are committed to providing our customers with the highest level of protection possible providing UL-752 standards up to .50 cal AP protection.

Frequently Asked Questions

What is ballistic glass made of?

Ballistic glass is constructed from multiple layers of glass and high-strength polycarbonate materials bonded together to form a protective glazing assembly. The layered design allows the system to absorb, slow, and disperse the energy of a ballistic impact rather than shatter on contact.

The number of layers and overall thickness vary depending on the level of protection required and the expected threat environment.

How does ballistic glass differ from security film?

Ballistic glass is designed to stop bullets, while security film is intended to delay forced entry. Security film may resist shattering but cannot provide bullet-resistant protection like laminated ballistic glass.

How long does ballistic glass last?

Ballistic glass can last 15–25+ years depending on the material type, environment, and maintenance. Glass-clad polycarbonate (GCP) systems typically offer the longest lifespan because they protect the inner polycarbonate layer from UV exposure and abrasion.

Can ballistic glass be installed in existing windows?

Yes. Many ballistic glass systems are designed for retrofit applications, allowing existing openings to be upgraded without full structural replacement, depending on framing conditions and protection requirements.

How thick is ballistic glass?

The thickness of ballistic glass depends on the required level of protection and the anticipated threat. Lower handgun-rated assemblies are typically thinner, while higher rifle-rated configurations require additional layered construction and increased overall thickness.

How do I determine the right ballistic glass level for my facility?

The appropriate protection level depends on the facility’s risk profile, location, and operational use. Factors such as expected threat type, public exposure, and structural conditions all influence system selection.

Kontek works with clients to evaluate these considerations and recommend a suitable configuration.
