IntruderGuard™ for Transparent Home Security » Viridian Glass


Residential security laminated glass

IntruderGuard™ is a specialised laminated glass that has an interlayer that is four times thicker compared to standard laminates. Specifically developed to offer a resilient and enduring barrier against intruder entry.

IntruderGuard™ aesthetically looks like normal glass but provides a barrier to forced entry that is 20 times harder to break through than standard float glass.

Typically used in residential applications with vulnerable entry points, IntruderGuard™ is ideal for providing extra resistance to invasion as it is designed to resist attacks from a variety of common hand tools and physical forced entry.
