RC3 burglar-resistant glazing
What is the RC classification for glazing?
The European Community has implemented the Resistance Class (RC) as a classification system for the burglary resistance of security systems, such as windows and glazing.
RC1 indicates the lowest resistance class, while RC2 is stronger and RC3 is well able to withstand burglary and opening attempts.
The Resistance Class measures the time of resistance: the longer a window, door, grille or window is able to maintain integrity, the higher its class.
