Frequently Asked Questions Correctional Facilities Glass
What makes detention-grade glass different from standard glass?
Detention-grade glass is specifically engineered for high-security environments, offering superior resistance to impact, forced entry, and ballistics. Unlike standard glass, it often incorporates laminated layers, polycarbonate interlayers, or reinforced materials to prevent breakage and spalling (dangerous glass shards).
What are the main types of security glazing used in correctional facilities?
Correctional facility windows rely on a few common types of security glazing:
- Laminated Security Glass - Multi-layered glass and plastic interlayers for impact resistance.
- Glass-Clad Polycarbonate - A combination of glass and polycarbonate for bullet resistance and flexibility.
- Insulated Security Glass - Provides thermal efficiency along with security.
- Fire-Rated Security Glass - Meets fire protection codes while maintaining strength.
Does detention glass prevent breakage?
While no glass is completely "unbreakable," detention glass is designed to resist breakage and prevent penetration. Some variations will crack but remain intact to maintain security. The level of protection depends on the glass construction and rating.
Is bullet-resistant glass required in all correctional facilities?
Not necessarily. Bullet-resistant glass is typically used in control rooms, sally ports, prison visiting room glass installations, and entry points where firearm threats are a concern. Lower-security areas may use impact-resistant but non-bulletproof glazing.
How is the strength of detention glass measured?
It is tested against various industry standards, including:
UL 752 – Bullet resistance (rated from Level 1 to Level 8- See our Defender® product line).
ASTM F1915 – Forced entry and attack resistance.
NFPA 80 – Fire-rated glazing compliance.
ASTM F1233 – Glass security glazing classification.
Can security glazing be used in inmate cells?
Yes, but it depends on the application. Laminated glass with polycarbonate layers is often used in jail cell windows to prevent self-harm while maintaining visibility for monitoring.
How does detention glass prevent contraband passing?
By using multi-layered laminated glass or polycarbonate, the glazing remains intact even if struck, preventing inmates from creating openings to pass objects through.
Can security glass be tinted or one-way for privacy?
Yes, security glass can include tinted, frosted, or one-way vision coatings to allow correctional officers to monitor inmates without inmates seeing out.
