ᐅ Resistance Classes for Windows & Doors (S2, RC2N, RC, etc.)

Hello everyone,

Last week we selected samples for windows and doors and now need to decide on the security class. This concerns 8 windows, 1 sliding door, and the apartment door.

The options are:

1. Windows in RC2 ~ additional cost approx. 6,000 euros
2. Windows in RC2N ~ additional cost approx. 3,000 euros
3. Windows in S2 (standard for houses) ~ additional cost approx. 1,000 euros

S2 includes the following features:

• Fittings: perimeter fittings with 7-14 mushroom head locking points + security strike plates
• Handle: drill protection and lockable with at least 100 Nm
• Anti-lift device: none
• Glazing: standard triple glazing
• Bonding: none
• Performance certificate: none

According to the supplier, the fittings for S2, RC2N, and RC2 are identical. The differences in RC2N mainly relate to the installation method and bonded glazing, which can be retrofitted for about 40 euros per window.

For the apartment and front doors, S2 would each cost an additional 200 euros. RC2N and RC2 would certainly be considerably more expensive.

My feeling leans towards the "standard for houses" option because a) we are in a newly built residential area, b) there is no increased risk of burglary, c) doors and windows would have the same standard, and d) it would not strain the budget.

I would appreciate your opinions on this topic.

Best regards,

In my opinion, the standard level of security for houses is sufficient. I don’t see any added benefit in having more security. Why? Based on my own experience over recent years. Break-ins have only occurred in sheds, garden huts, and neighbors’ garages. No one has attempted to break into the house itself because it is too complicated.

Choose RC2 if you live in an area where house break-ins are common.

I am not aware of an increased risk of burglary. Therefore, I also lean towards the "standard house" option. Personally, the likelihood of someone pulling the entire window out of its frame seems very low to me.

Yes, if you live in a quiet area, all the better. Here, RC2 is the minimum standard. Anything below that is not worth considering.

This is a subjective decision. If someone wants to break in, they can do so even with RC2 protection. The real question is whether you want to deter a "casual" burglar and avoid minor damage—in that case, RC2 is definitely the right choice. If professional burglars come, RC2 won’t be enough, but then you have a different problem. We also have everything on the ground floor rated as RC2 and accepted the additional cost. Why? Because the feeling that even a “casual” burglar was in the house is definitely worse for us than the investment. But as I said, everyone has to decide for themselves.
