JailGuard™ – Specially Designed for Correctional Facilities » Viridian Glass


Specialist security laminate

JailGuard™ is a specialist security laminate for use in correctional facilities such as police stations, jails and remand centres.

Manufactured using a variety of glass types and thicknesses combined with high end security interlayers, JailGuard™ is tough enough to meet the standards of correctional facilities.

JailGuard™ is designed to resist attacks from typical hand tools that might be found within correctional facilities such as brooms, mop buckets, billiard balls and hammers.

Simulated attack conditions using axes, wood splitters, crowbars and other hand tools have shown products within the JailGuard™ range capable of resisting invasion with repeated blows for up to 30 minutes.
