Our bullet-resistant fiberglass panels Level 5 systems meet UL 752 Level 5 performance requirements. That means they stop 7.62mm rifle rounds under controlled test conditions. Security directors, architects, and risk managers specify this level when a threat assessment calls for protection beyond resistance to handguns. If your environment carries elevated risk, Level 5 protection provides the strength and confidence your team expects. Learn more about UL 752 Level 5 bullet-resistant barriers from ArmorCore.

Why Bullet-Resistant Barriers Are Critical

Security measures such as surveillance systems and access control are important, but physical barriers determine how well a facility resists forced entry and ballistic threats. Walls, doors, and transaction areas are often the most vulnerable points in a structure.

Bullet-resistant barriers reinforce these areas by strengthening wall assemblies, securing transaction counters, and protecting administrative offices and safe rooms. Properly installed ballistic materials are designed to slow or stop projectiles, providing critical response time during an incident.

UL 752 Level 5 standards require materials to stop a 7.62mm full-metal-jacket rifle round. This classification addresses higher-energy rifle threats that exceed the performance of lower UL levels.

Facilities that commonly specify UL 752 Level 5 protection include:

  • Government facilities: Courthouses, municipal buildings, and law enforcement offices requiring rifle-rated protection
  • Financial institutions: Banks and credit unions with high-value assets and controlled access areas
  • Corporate headquarters: Facilities protecting executives, proprietary data, and critical infrastructure
  • Educational campuses: Administrative offices and controlled-entry areas with elevated security requirements
  • Critical infrastructure sites: Utilities and transportation hubs supporting essential operations

Level 5 Bullet-Resistant Barriers

ArmorCore manufactures bullet-resistant fiberglass panels Level 5 using composite materials designed to absorb and disperse ballistic energy. These panels are engineered to maintain structural integrity after impact, limiting penetration and spalling.

Compared to steel plate systems, composite panels reduce weight and simplify installation. Contractors can cut and shape panels on-site and integrate them into standard wall assemblies without major structural redesign.

For glazing applications, Level 5 panels are often paired with separately specified UL 752 Level 5 bullet-resistant glass to maintain consistent protection across walls and openings. ArmorCore does not supply glazing products but works alongside project teams to align panel performance with overall system requirements.

Application

This Level 5 bullet resistant fiberglass barrier is most commonly used as a protection barrier against military ball full metal copper jacket ammunition fired from a hunting rifle, such as the 308 Winchester (7.62mm) or a military rifle with muzzle energy of 2519-3048 foot-pounds (3416-4133J)

Level 5 Bullet Resistance Features

ArmorCore works with architects, contractors, and security consultants to define coverage areas, panel thickness, and installation strategy based on project requirements. Material selection is aligned with threat level, structural constraints, and integration requirements.

ArmorCore builds Level 5 barriers with performance and real-world installation in mind:

  • UL 752 Level 5 performance: Panels are tested to meet rifle-rated ballistic standards
  • Lightweight composite construction: Reduces handling complexity compared to steel alternatives
  • Custom fabrication: Panels are waterjet cut to match project-specific dimensions and layouts 
  • Seamless integration: Designed for installation within conventional wall and door assemblies
  • Manufactured in the USA: Produced under controlled manufacturing conditions

Specify UL 752 Level 5 Protection with ArmorCore

When a project requires UL 752 Level 5 protection, selecting the right material and installation approach is critical to achieving consistent ballistic performance. ArmorCore provides bullet-resistant fiberglass panels Level 5 with custom fabrication capabilities and short lead times to support demanding project schedules.
