When installed and locked, burglar-resistant doors and windows are designed to resist a forced break-in attempt for a certain period of time through the use of physical force and/or the use of defined tools.
This means that burglar-resistant components are not "burglar-proof", as it is only a question of time, the type of perpetrator and the tool used by the perpetrator before a burglar-resistant component can be opened. The press has repeatedly reported on the (non-standardised) methods used by perpetrators to gain access to buildings or valuables.
The resistance that building elements successfully offer to burglary attempts is specified in resistance classes. They range from RC1 to RC6.
Pragmatic resistance
In the private sector, resistance class RC2 or RC3 is considered common and sufficient. In the RC3 test, a cow's foot with a length of 70 cm is already used. From RC4 upwards, commercial properties are assumed where the perpetrators also use cordless drills and percussion tools. In the RC5 tests, jigsaws and angle grinders are added, while in RC6 many high-powered electrical appliances are used.
It is understandable that people often want the highest possible protection - however, it makes no sense to plan for the highest resistance classes in private homes - pragmatically speaking, a maximum of RC3 is sufficient.
Important: The structural elements must be installed in accordance with the manufacturer's installation instructions. It is precisely the pressure-resistant backing of the elements in conjunction with the correct number and dimensions of the fasteners that ensures that the elements withstand the test scenario.
