Intrusion protection

Windows, doors and façades that offer resistance - for when uninvited guests should remain outside.

Spectacular raids such as the theft of the priceless treasure from the Grünes Gewölbe in Dresden Castle make the headlines.

But, every day, countless robberies take place in homes and the perpetrators not only steal everything they can make money from but also leave behind a trail of destruction. What remains is the horrible feeling of being the victim of arbitrary aggression.

Burglar-proof windows and doors made from steel profile systems offer protection from this traumatic experience.

Burglar-proofing and resistance

Burglar resistance is classified according to DIN EN 1627. The standard tests the resistance of various building components and puts them in resistance classes RC 1 N, RC 2 N and RC 2 to RC 6.

The N in the first two categories refers to the possibility of certain aspects being regulated on a national level. For example, in Germany, none of the requirements from the lower resistance classes RC 1 N and RC 2 N are applied to window glazing, but in Austria they are.

Bullet resistance

If bullet resistance of a building component is required, it is usually advisable to make the accessible entrance and facade areas burglar-resistant at the same time.

Selecting the appropriate level of resistance

In the private sphere, RC2 is recommended as the minimum requirement. This resistance class provides protection against break-in attempts with simple tools such as screwdrivers, pliers and wedges. Windows and doors of resistance class RC3 offer greater levels of protection: They must withstand at least five minutes of crowbar assault.

Experience has shown that burglars give up the longer the building part resists.

RC4 to RC6 are resistance classes that impose even higher requirements for intrusion protection. These components offer resistance against even experienced burglars brandishing powerful electric tools such as drills, jigsaws and angle grinders.

Reliable protection

Burglar-proof door, gate, window and façade systems constructed from Jansen steel profile systems are used on government buildings, museums and galleries as well as correctional facilities, banks and police stations.

In high-end residential housing, too, glazed burglar-proof constructions that use slim steel profiles can reliably satisfy the occasionally contradictory requirements of greater transparency and openness on the one hand and protection against burglary and vandalism on the other in an aesthetically pleasing manner.
