Which security level to choose for windows?

Hello! I wanted to ask which security level you chose for your windows? I was recommended RC2 on the ground floor and RC1N upstairs. The architect says that is not necessarily needed, and it would be an extra cost of about €1600. Best regards

We have chosen RC 2 on the ground floor and RC 2 n on the upper floor. For this, we will receive a certificate for the windows, but the installation cannot be certified due to the roller shutters and venetian blinds. We can live with that.

Is that really (your) architect or the planner of the construction company?

Sixteen hundred euros for more security on all windows of one floor would not make me hesitate for long.

Sometimes it makes sense to equip windows on the upper floor as if they were on the ground floor: for example, if they are difficult for neighbors to see and easily accessible over the garage roof.

That is indeed correct. 2 windows above the carport are equipped with RC 2.

which security level have you chosen for your windows?

On the ground floor RC2N and on the upper floor RC1. I don't really see the risk of glass breakage (exposed location of the property). Additional cost in total (including lockable window handles for 10 sashes) 1,000 euros for 15 sashes.

I would already take RC2 on the ground floor.
