Bullet-Resistant Glass & Ballistic Polycarbonate Laminates
For banks, government facilities, and secure reception areas across Houston, ballistic security is a critical operational requirement. Bullet-resistant glass systems are engineered to absorb the energy of bullet rounds, protecting personnel from high-level threats while maintaining clear lines of sight.
Understanding bullet resistant glass Science
Ballistic glass is a composite material made of alternating layers of glass and polycarbonate sheets. The hard glass layer flattens the bullet, while the flexible polycarbonate layer absorbs the impact energy and prevents spalling (glass fragmentation on the secure side).
Key Engineering Properties & Benefits:
- Structural Integrity: Designed to withstand significant wind load pressures and surface impact stresses.
- Safety Compliance: Meets strict local municipal building codes and safety regulations.
- Aesthetic Control: Available in low-iron, frosted, tinted, or back-painted configurations.
- Thermal Efficiency: Helps regulate internal temperatures, minimizing HVAC stress.
Texas Local Building Requirements
We engineer and install custom bullet-resistant window systems that meet UL 752 standards, ranging from Level 1 protection (9mm handguns) to Level 3 (44 Magnum) and higher, ensuring safety in secure spaces.
Frequently Asked Questions
What is spalling in ballistic glass?
Spalling refers to the dangerous shards of glass that fly off the back of a bullet-resistant window when it is hit. We install low-spall or no-spall polycarbonate-backed systems to protect personnel.
Can bullet-resistant glass be installed in standard window frames?
No. Ballistic glass must be installed in matching ballistic steel or armored aluminum frames. Standard frames will collapse under impact, causing the entire window system to fail.
