Viridian JailGuard is a specialised security glass primarily geared for use in correctional facilities such as police stations, remand centres, juvenile justice facilities and jails. Products within the JailGuard range are designed to withstand a variety of attacks from hand tools and typical implements such as brooms, mop buckets, billiard balls and other objects found within correctional institutes. Simulated attack conditions using axes, wood splitters, crowbars and other hand tools have shown products within the JailGuard range capable of resisting penetration for extended periods.

JailGuard products are manufactured using a variety of glass types and thicknesses combined with high-end security interlayers. JailGuard can also incorporate low spall films if required.
