The CellGuard™ custodial window system has been designed to satisfy the stringent criteria set out within the Home Office Police Building Design Guidance and has been developed, tested and approved in conjunction with the Home Office for use in Police Custody Suites.

CellGuard™represents a new approach in custodial fenestration and delivers enhanced security, excellent thermal performance and light transmission, offering over a third more available light than traditional products. CellGuard™is designed to be aesthetically pleasing. The thermally broken steel frame houses a single pane of CellGuard™composite glass, which has been engineered to withstand  sustained attack.

Bars and grilles are no longer necessary, providing a less institutional environment for detainees, visitors, staff whislt reducing the visual impact on the wider community.
