Keep out thieves!

Burglary protection starts with your windows!

Are you interested in burglar-proof windows? Rightly so!

Burglary resistance is an important point to be considered when buying new windows as, in most cases, this is where thieves tend to break in. And the burglars will take anything they want; anything but the risk of wasting too much time trying to open a burglar-proof window. Every minute that the window resists a break-in counts. Experience has shown that perpetrators usually give up after only a couple of minutes. That's why the police recommend a burglary protection class of at least RC2 when buying new windows.

With aluplast uPVC windows, you have already opted for ultimate safety in the sash.

Overview of RC resistance classes

In the past, a range of resistance classes were used to differentiate between categories of burglary resistance. In September 2011, a new series of European standards was published in relation to burglary protection. The new standard (DIN EN 1627) now differentiates between RC 1 N to RC 6. RC stands for resistance class.
The following table lists the assumed mode of break-in for resistance classes RC 1 N to RC 6.


DIN EN 1627 DIN V ENV 1627 (valid until 09/2011) Period of resistance Type of burglar / method used
RC 1 N
3 min Components in this category only offer basic protection against attempted break-ins using physical strength, such as kicking, pulling, etc. In this class, only windows with standard glass are listed.
RC 2 N without safety glass 3 min Here, opportunist burglars use simple tools, such as screwdrivers, pliers, chocks, etc., to force open the locked component. As an attack on the glass should be ruled out, this glass uses standard glass only.
RC 2
3 min The type of burglar and method used are the same as the previous class. However, safety glass in accordance with EN 356 is required from class RC 2 and above.
RC 3
5 min The practised criminal uses an additional screwdriver and crowbar to break open the locked element.
RC 4
10 min To break in, the experienced criminal uses impact tools, saws and a cordless drill.
RC 5
15 min In addition, the experienced criminal uses electrical tools, such as drills, jigsaws, reciprocating saws and angle grinders with a maximum diameter of 125 mm.
RC 6
20 min The only difference to the previous resistance class is the use of an angle grinder with a maximum diameter of 250 mm.
