Alarm glass

Alarm glass refers to glass products with an alarm loop. The following versions are possible: as an electrically conductive paste baked onto thermally toughened safety glass, as a meandering wire inserted in the composite foil of the laminated safety glass or as a conductive functional layer on thermally toughened safety glass. The electrical resistance changes when the glass, the wire or the conductor loop breaks. A system attached recognises this difference and triggers an alarm.
